Abstract: Solar assisted chemical heat pump drying system for tropical region has been studied. A simulation has been done under the meteorological conditions of Malaysia. The system consists of four mean components, solar collector (evacuated tubes type), storage tank, chemical heat pump units and dryer chamber. The monthly efficiency for evacuated tube solar collector has been predicted to be between the range (59 – 64%) with the deference between mean collector temperature and ambient temperature 20 ºC. The solar fraction as a function of solar collector area has been studied. It was found that as the collector area increases the loss increases and hence the solar fraction increases. A monthly coefficient of performance for heating (COPh) for chemical heat pump has been predicted and the maximum value of 1.8 as function for solar collector area 10 m2 and storage tank size 0.2 m3 were found. Any reduction of energy at condenser as a result of the decrease in solar radiatio!
n which in the final decrease the coefficient of performance as well as decrease the efficiency of drying.
Keywords: evacuated tube collector efficiency, solar fraction, collector area, chemical heat pump, coefficient of performance, drying.

Abstract: The requirements for significant computational resources imposed by dynamic security assessment applications have led to an increasing interest in the use of parallel and distributed computing technologies. This paper presents an adaptive scheme that involves user-friendly flat application program interfaces for scripting and an object-oriented programming environment for distributed dynamic security assessment implementation. Functional parallelism and data parallelism are supported by each of the message passing interface model and TCP/IP model. Adaptive stochastic-based objectives and conservative parameter prediction techniques are used to produce more efficient data parallelism. Tests for a 39-bus network and a 3872-bus network are reported, and the results of these experiments demonstrate that the proposed scheme is able to execute the distributed simulations on either stand-alone personal computers, cluster systems, or a computational grid infrastructure and!
provide efficient parallelism for the given environment.

Title of the Paper: An Algorithm for Creation of an Optimized Adaptive Grid for Improved Explicit Finite Difference Scheme

Abstract: This paper deals with the two main shortcomings of explicit finite difference schemes: the use of a discretization grid with the same resolution over the entire problem space, and low level of precision and stability. We present a combination of two improvements. Their application is illustrated with the numerical simulation of the propagation of a light beam in a photonic lattice. The discretization problem is avoided by using a multi-resolution grid. An algorithm for the grid creation is developed and that algorithm is optimized for software implementation and parallelization. The efficiency of the algorithm is increased by further improving the precision of the explicit method by use of a multidimensional generalization of the Runge-Kutta scheme. Due to the multidimensionality and nonlinearity of the considered problem, our improved explicit finite difference gave better results than Crank-Nicholson scheme.

Abstract: Abstract The notation of projective topological group for a category of topological groups has been defined by Hofman [3]. Free topological groups have been of interest in the study of topological groups since their invention by Markov [5]. We consider final group topologies and their relations to comactness properties.We consider situation ensuring that a final group topology is locally compact. We are interested in situations where a colimit or direct limit is locally compact, a kw-Moody groups can be described as the colimit of an amalgom of subgroups (in the category of Hausdorff topological groups, and the category of kw-groups).

Abstract: An analysis has been developed in order to study the unsteady mixed convection flow of an incompressible fluid past an infinite vertical porous plate with thermophorisis particle deposition effect. The governing equations are solved numerically using an implicit finite difference technique. The selected numerical method is validated by comparing the results with the analytical solutions. Numerical results for the details of the velocity profiles which are shown on graphs have been presented. It is found that the steady state values of thermophoretic deposition velocity reached faster as the thermophoresis constant decreased and the temperature ratio increased.

Abstract: The objective of this paper is to develop a hierarchical model of a systolic array which solves differential equations by using Upgraded Petri Net (UPN). The Upgraded Petri Net presents a formal modeling tool, based on mathematical apparatus, used for simulation and analysis of processes, particularly at the register transfer level. Original software for modeling and simulations of Upgraded Petri Nets, PeM (Petri Net Manager), is developed and used for all models described in this paper. This software supports: UPN formal theory, graphical modeling, simulation and analysis of an UPN model. This paper includes a preface on the UPN theory, the UPN models formulation, the UPN models of a processing element of a systolic array which solves differential equation, their simulation and analysis. The first hierarchical level refers to the high level systolic array modeling. This model shows processing elements that calculate or pass their input to the output. Thus, the nex!
t processing element uses the results from the previous one. The second level model is more detailed and refers to a single processing element. This model is capable to generate solution of a differential equation through UPN execution based on Taylor's method. This execution is based on parralel firing of a group of transitions. The results are stored into a *.mem file inside the PeM. The suitability of UPN for modelling of the systems at different levels of abstraction is examined and established.

Abstract: Mobile radio channel characterization using linear operators of affine group is presented. The foundation of this approach is primarily based on the natural extension of basic concepts of time-scale representations of wavelet-type to the analysis and representation the nonstationarity associated with the real-time mobile radio channel. We provide an operator-based characterization initiated by the need to present an intuitive and physical approach towards describing and representing the various effects of the channel. The concepts of delay-scale spreading function and operator as well as delay-scale scattering function and operator is introduced. We established the relationship between the continuous wavelet transform and these functions/operators by employing the powerful tool of group theory. We also derived canonical expression for the corresponding channel by discretizing the channel using frame concept. The practical relevance of our approach is illustrated vi!
a deterministic examples and the associated simulations.

Abstract: : Maintaining the glucose concentration in normoglycemic range in Type I diabetic patients is challenging. In this study H‡ control is applied for the insulin delivery to prevent the hyperglycemic levels in a type I diabetic patient. From a control theory point of view, the blood glucose regulation problem is reformulated as a tracking one. A glucose tolerance curve (GTC) validated from several healthy subjects is used as reference signal. A nonlinear compartmental model is linearized around nominal condition. And reduced for controller synthesis. H‡ design is carried out using Riccati equation based. The performance of the controllers was studied by implementing them into the nonlinear model. Sensitivity and Complementary sensitivity functions show the nominal and robust performance of the closed loop system

Abstract: In this paper, we propose a new method to design a grey prediction system controller using output feedback. The optimal reduced order model will be used to retain the physical meaning of the output states. By using only the output states feedback, the control strategy can be implemented easily. The grey prediction method adopts the forecasting information from the output state variables to control system behaviour. As a result, it reduces the oscillation and enhances the dynamic stability of the system. The advantages of the proposed method are verified through a detailed simulation of a multi-machine power system. Responses of the system with the proposed method and full state feedback optimal control are included for comparative analyses. In conclusion, the effectiveness of the grey prediction system controller in enhancing the dynamic performance stability is much better than the traditional optimal control methods.

Abstract: This paper optimizes the introduction of broadband internet service in an existing PSTN network, by the means of a techno-economical model. The proposed model determines the optimal timing of introduction of ADSL technology to an urban telephone network, as seen by the Network Access Provider perspective. The implementation strategy is determined on the basis of the maximization of the total income while keeping capital expenditures under a given budget. Costs and Incomes are predicted based on current prices of both charging rates and broadband equipment. The feasible policies concern the evolution of the Central Offices of the urban network, as well as the introduction of centralized equipment, such as routers and aggregators. The model first determines the number of feasible policies and the costs associated with each one, using inputs concerning the network status, i.e., the number, position and capacity of exchanges and links, broadband services demand predict!
ions, technical specifications as well as pricing predictions and, by the means of a charging (revenues) model produces the alternative policies for each Central Office (CO) as well as for the introduction of routers and aggregators along with their corresponding costs and incomes. These results are then fed to the second part of the model, which, using the costs and revenues associated with each alternative policy for each CO and for each type of centralized equipment, selects the overall optimal network policy, by estimating the most profitable combination of CO policies, one for each, as well as the policies concerning the introduction of routers and aggregators, by keeping the sum of the corresponding costs under certain limits. The overall policy is determined by the means of an IP (Integer Programming) algorithm. The Integer Programming algorithm consists of an objective function maximized with respect to a number of constraints. The model was implemented in the case !
of the urban telephone network of Patras/ Greece, using several realis
tic assumptions for the estimation of the costs and revenues, as well as typical current configurations for estimating the costs involved. The results obtained proved the validity of the model.

Abstract: With the structure miniaturization of SF6 Circuit Breaker in three-phase-in-one-tank GIS, improvement of internal structure design and layout should be taken into account to balance the electric field intensity distribution among phases. By calculating the three-dimensional electric field intensity distribution in GIS with FEM to guide and optimize its internal structure will improve the electric field intensity distribution status among each phase or whole field domain and can avoid insulated medium breakdown due to excessiveness of local electric field intensity. Based on the character of the complex structure of the SF6 circuit breaker in three-phase-in-one-tank GIS (Gas Insulated Switchgear), the modified preconditioned conjugate gradient (MPCG) algorithm applied to solve multi-nodes and multi-elements large sparse real positive defined symmetric matrix is analyzed. The program diagram of MPCG algorithm is also proposed. According to the sparse symmetric chara!
cter of coefficient matrix, the method of storing coefficient matrix effectively and rapidly is studied and new data structure is adopted. The finite element calculation mathematical model and physical equations of SF6 circuit breaker are founded in this paper. The large sparse matrix is solved by using the MPCG algorithm. The electric field intensity and potential distribution is calculated under power frequency voltage and their corresponding cutaway charts and planforms are given. They can provide a useful design parameter for designing the circuit breaker optimum configuration in GIS.

Abstract: E-learning leads to evolutions in the way of designing a course. Diffused through the web, the course content cannot be the direct transcription of a face to face course content. A course can be seen as an organization in which different actors are involved. These actors produce documents, information and knowledge that they often share. We present in this paper an ontology-based document-driven memory which is particularly adapted to an e-learning situation. The utility of a shared memory is reinforced in this kind of situation, because the interactions do not usually occur in the same place and in the same time. First we precise our conception of e-learning and we analyze actors needs. Then we present the main features of our learning organizational memory and we focus on the ontologies on which it is based. We consider two kinds of ontologies: the first one is generic and concerns the domain of training; the second one is related to the application domain and is!
specific to a particular training program. We present our approach for building these ontologies and we show how they can be merged

Abstract: In this paper a new rotor field orientation control of six phase induction machine is proposed. The machine has two three phase windings spatially shifted by 30 electrical degrees. The dynamic model of the machine is based on the three two dimensional orthogonal subspaces. The proposed method uses a simple estimator for identifying rotor flux and its orientation. To eliminate the extra harmonic currents of stator windings that produce losses, space vector PWM technique and double synchronous frame current controller is employed. The simulation results illustrate the validity and efficiency of the proposed method.

Abstract: Multi agent system (MAS) reputation has some shortcoming in the existing model, such as system dynamic analysis and storage capacity. Based on dynamic analysis of MAS trusting model and its problems on system storage, this paper proposes a new trust mechanism which uses combined dynamic time to modify the weight of time. To mimic the dynamic ability of MAS system, we introduce a new parameter of dynamic adjustment, in order to its problems on system storage. Simulation experiments show that the new mechanisms have significant improvements on trust evaluation and storage efficiency, compared with the traditional model of trust.

Abstract: In today¡¦s competitive environment, a successful company must provide better customized services, that are not only acceptable to customers but satisfy their needs as well, in order to survive and succeed in gaining an advantage against competition. It has been proven by many studies that it is more costly to acquire new customers than to retain old ones. Consequently, evaluating current customers in order to enhance their lifetime value becomes a critical factor to decide the success or failure of a business. This study applies data from customer and transaction databases of a department store, based on the RFM model, and does clustering analysis to recognize high value customer groups for cross-selling promotions. Study findings show that clustering analysis can locate high value customers, and the company can then apply appropriate target marketing to enhance their lifetime value effectively. The implication for the marketer is that leveraging techniques of d!
ata mining can make the most from data of customers and transactions databases and thus create sustainable competitive advantages.

Abstract: Kalman filtering is a powerful technique for the estimation of the speech signal observed in additive background noise. This paper presents a contribution in the enhancement of noisy speech with white and colored noise assumption. Some tests were performed with ideal filter parameters, others using the Expectation Maximization (EM) algorithm to iteratively estimate the spectral parameters of the speech and noise. Simulation results show that the application has the best performance evaluated with objective quality scores, observation of the waveforms, as well as informal listening tests in the case of Noizeus database.

Title of the Paper: Implementation and Control of Grid-Connected Power Conditioner for Distributed Generation System
Authors as they appear in the Paper: Jianfei Zhao, Jianguo Jiang
Email addresses of all the authors: zjfei@sjtu.edu.cn, jiang@sjtu.edu.cn
Number of paper pages: 11
Abstract: A new control system of grid-connected power conditioner for distributed generation system is proposed and studied. The power conditioner consists of a dc-dc boost converter and a three-phase dc-ac voltage source inverter. The proposed control system consists of voltage and current control strategy, compensation control strategy and anti-islanding control strategy. The interrelationships of the control strategies are also designed so as to form a protection system for the distributed generation system. Thus, it can be considered as a total solution of the control strategy for distributed generation system. The power conditioner with the proposed control system can operate with high efficiency, high power factor and low current and voltage total harmonic distortion in a wide output range. The operation of the proposed control scheme is confirmed by the experimental results on a 10 kW design example.

Abstract: In this paper, a trade-off between noise reduction and the preservation of actual image features has been made in a way that enhances the diagnostically relevant image content. Data is transformed into the wavelet basis. In this, large coefficients are mainly the signals and the smaller ones represent noise. By suitably modifying these coefficients, the noise has been efficiently removed from the data. In this paper, a wavelet based sub-band filtering method has been applied to enhance the micro calcifications present in digital mammograms by inhibiting noise. In this thesis work, we have used wavelet transforms to denoise the medical images. Quantitative evaluation of various image restoration method has been done based on quantitative ratios such as CII, contrast enhancement index etc. Results as obtained in this case demonstrate that the proposed method improves the quality of the image more than the other enhancement methods.

Title of the Paper: Modeling the nonlinear vibration response of a cracked rotor byTime Delay and Embedding Technique

Email addresses of all the authors: alugoaa@unisa.ac.za,alugongo@yahoo.com

Abstract: In this paper, a non-linear model for a cracked rotor is established based on constitutive equations and local flexibility due to a transverse breathing crack on a rotor shaft. The crack is characterized by a switching function and change in shaft stiffness, whose variation and value defines the closing-opening or breathing condition of the crack during rotation of the shaft. The model accounts for the rotor shaft weakening parallel and perpendicular to the direction of the crack opening. The system equation bears discontinuity, and its numerical solution exhibits bifurcation and chaos. The model is used to investigate the dynamics of the vibrating rotor system, and the crack force reconstructed' by Time delay and Embedding Technique. The crack force manifests the action of the crack on the rotor. It is observed that the largest computed Lyapunov exponent of the simulated time series is a good and sufficient indicator of the system's chaotic state. Various scenari!
os of the system at sub-critical and super-critical speeds have been simulated and discussed.

Title of the Paper: Full-scale Nonlinear Analysis of LHL Ga As IMPATT Amplifiers

Email addresses of all the authors: saidhassan1@yahoo.com
Number of paper pages: 13
Abstract: Abstract: The analysis of LHL Ga As IMPATT Diode structure has been developed on the basis of IMPATT nonlinear model. The paper presents a detailed analysis of the effect of peak value of the microwave signal and the operating conditions on the performance of GaAs IMPATT amplifiers. It is indicated that the variation of peak RF voltages gives rise to three modes of operation (conventional mode and two high-efficiency modes) . During the high-efficiency modes, the induced current has one or two additional peaks at the proper phase angles in the RF cycle due to the bunching and acceleration of the avalanche-generated packet of electrons. The diode conductance and the generated RF power increase sharply during the high-efficiency operation. Important conclusions concerning the effects of the dc bias current and operating frequency on the performance of this device are drawn. The results presented here are obtained using a full-scale computer simulation program tha!
t takes fully into account all the physical effects pertinent to the IMPATT diode operation .They will help optimize the Ga As IMPATT structure and its operating conditions.

Abstract: This paper proposes a new model to analyze the behavior of the WFQ scheduler in a DiffServ network node with LRD traffic. The model aims to simplify WFQ by treating queues separately. The RTT, Ploss and latency values for the model under several different circumstances (namely, different utilization factors, buffer sizes and weight setups) are compared to those obtained via NS-2 simulations. One of the advantages of this model is that much less processing time is needed to reproduce results that could otherwise only be obtained through lengthy simulations.

Abstract: In this paper is addressed the issue how to provide QoS control and improve performance in high speed Optical Burst Switching (OBS) networks. In order to provide better proportional differentiated services are proposed new algorithms: a burst assembly algorithm (named adaptive timer-based) with traffic shaping functions and a Delayed Burst Assignment (DBA) scheme, both able to reduce the variance of assembled traffic and to improve the burst loss performance. A precise analytical model to study the performance of the assembled traffic in high speed networks is also presented. The simulation results show that the proposed algorithms have better performance in terms of edge buffering delay and can lighten burst loss ratio for TCP flows of the OBS network.

Abstract: The problem of sorting an array $A=(a_1,a_2,...,a_n)$ is considered when the input elements are drawn from a linear range in $n,$ we call it integer sorting. We extend the domain of input data for the algorithm that solves the integer sorting on Sum-CRCW PRAM to be work on any distribution. The modified algorithm is deterministic with optimal cost, runs in $O(\frac{\log{n}}{\log\log{n}})$ time using $\frac{n\log\log{n}}{\log{n}}$ Sum CRCW processors and uses linear space.

Abstract: Recently, biology techniques become more and more popular, as they are applied to many kinds of applications, authentication protocols, biochemistry, and cryptography. One of the most interesting biology techniques is DNA and using it in such domains. Hiding secret data in DNA becomes an important and interesting research topic. Some researchers hide the secret data in transcribed DNA, translated RNA regions, or active coding segments where it doesn't mention to modify the original sequence, but others hide data in non-transcribed DNA, non-translated RNA regions, or active coding segments. Unfortunately, these schemes either alter the functionalities or modify the original DNA sequences. As a result, how to embed the secret data into the DNA sequence without altering the functionalities and to have the original DNA sequence be able to be retrieved is worthy of investigating. This paper applies reversible information hiding scheme on DNA sequence by using the revers!
ible contrast mapping technique. The reversible property makes the secret data hidden in anywhere in DNA without altering the functionalities because the original DNA sequence can be recovered exactly in our scheme

Title of the Paper: Incorporating Voltage Stability Limit in Competitive Energy Market Optimal Dispatch
Authors as they appear in the Paper: muwaffaq i. alomoush

Number of paper pages: 10
Abstract: In restructured power systems, it has been a common practice to maximize a social-welfare function to find the optimal dispatch schedules of generators and loads. Voltage stability limit is usually ignored in this dispatch decision process. Even though exclusion of voltage stability limits from dispatch process may yield more economic schedules, this dispatch may lead to a less secure operation of the system, where the system may operate very close to the voltage collapse point. Therefore, this paper explores the representation of the steady-state stability limit in the social-welfare optimization process of an energy market that involves both spot and bilateral contracts. The paper investigates impacts of considering satiability limit, with and without bilateral contracts, on energy market outcomes such as social welfare, degree of fulfillment of spot market transactions, energy prices, and total system generation or load. The paper shows that incorporating stabil!
ity limits in system modeling tends to decrease social welfare value, increase energy prices, reduce system utilization, and may reduce feasibility of desired spot market transactions.

Number of paper pages: 11
Abstract: Abstract: A simple span T-beam bridge was analyzed by using AASHTO specifications and Loadings as a one dimensional structure, then a three- dimensional structure was carried out by using finite element plate for the deck slab and beam elements for the main beam. Both models were subjected to 1.5 AASHTO Loadings and at the same locations to produce maximum bending moment and maximum shear. The results were analyzed and it was found that the results obtained from the finite element model are smaller than the results obtained from one dimensional analysis, which means that the results obtained from AASHTO loadings are consecutive.

Abstract: In this paper we present an efficient A* algorithm to solve the Directed Linear Arrangement Problem. By using a branch and bound technique to embed a given directed acyclic graph into a layerwise partition search graph, the optimal directed ordering is then be identified through a A* shortest path search in the embedding graph. We developed a hybrid DC+BDS algorithm to approximate the optimal linear arrangement solution, which includes directed clustering and bidirectional sort technique. Along with a lower bound based on the maximum flow technique, this approximation solution is used as an upper bound to prune the state space during the A* search. In order to reduce the memory requirement of the A* search, we also discuss a implementation of the relay node technique from Zhou and Hansen [22].

Abstract: This paper describes GRAF-ANT (Graphical Framework for Ant Colony Optimization), an object-oriented C# framework for developing ant colony systems that we have developed. While developing this framework, abstractions that are necessary for ant colony optimization algorithms were analyzed, as well as the features that their implementing classes should have. During creation of these classes, several problems were solved: implementation of individual ants and ant colonies, connection between visualization and problem spaces, creation of a multithread application in which multiple ant colonies can communicate, creation of a problem independent graphical user interface (GUI), establishing an opportunity for hybridization of ACO (Ant colony optimization). Effects of this hybridization to different variations of ant colony systems is analyzed. The use of the GRAF-ANT and its suitability is illustrated by few instances of the Traveling Salesman Problem (TSP). We also prese!
nt a concept of escaping ACO stagnation in local optima, named suspicious path destruction, that is also a part of GRAF-ANT.

Abstract: The achievement manner of a stable relationship and on equality postures between bank-client/customer it' an objective consistently and very carefully pursued by every bank in the world. The European Commission sustains that different rules for banking consumer's protection of each country member. The consumers groups oppose to these protection rules, sustaining that the local legislative men are the most suitable to solve this problem. On the other hand, banks are oriented in the correlated analysis of the factors of influence of their behaviour, however it will not omit the monitoring of the competitors' behaviour (the services offered by other banking institutions).

Abstract: The consumption of plastic materials is now 20-times greater than 50 years ago. In the car industry plastic components are increasingly used to replace metal. Recycling of plastic materials from end-of-life vehicles (ELV) is still an unsolved problem. The most delicately problem in materials recycling from ELV is the sterile recovering, which in present is sent at the municipal waste, causing environmental problems. Some experimental results for recovering plastic materials from bumpers are presented in this paper. Different samples obtained from bumpers were analyzed and mechanical characterized for the identification of polymers and their level of mechanical strength and thermal stability. The recovered materials from ELV bumpers presented a still high level of mechanical strength and a still good thermal stability. New materials with interesting properties were obtained by compounding these samples with wood flower and virgin polymers.

Abstract: Ad-hoc On-demand Distance Vector (AODV) provides scalable and effective solution for packet routing in mobile wireless ad hoc networks, however, the path generated by this protocol may derivate far from optimal because of inconsideration of node power ,load unbalance and link state£¬resulting in energy consumption of each nods is imbalanced and reduce the lifetime of whole networks. Based on the basic AODV protocols, an improved protocol is presented in this paper. When the protocol is selecting a route, node power, load status and link state between nodes are all considered. The proposed protocol can improve the network performance. Through the simulation on NS2, it is confirmed that the improved AODV protocol has higher package delivery ratio, lower end to end delay and lower routing overhead than basic AODV protocol.

Abstract: Efficient treatment of reject water originating from sludge digestion process was achieved by implementing a moving bed bioreactor. Since the ongoing processes in the reactor were unclear, model development was chosen in order to map them. To describe biofilm processes a newly presented zero-dimensional biofilm model [27] was chosen. Simulation data in the study of Plattes et al. [28] were promising for municipal wastewater but it did not meet the expectations in case of wastewater with high ammonia content. Therefore four step nitrogen removal was implemented in the 0D biofilm model. Steady-state simulation showed that processes over nitrite were of great importance in the system. The results also indicated that to a certain degree ANAMMOX (anaerobic ammonia oxidation) reaction took place as well. The special structure of the moving bed bioreactor with protected microorganism colonies was assumed to be the reason for that.

Abstract: In this paper we introduce a novel technique that can be used as an indicator of the number of active signal sources in convolutive signal mixtures. The technique is designed so that the number of sources is estimated using only recorded signals and some marginal information, such as possible minimum and maximum triggering frequencies of sources, but no information on mixing matrix, other parameters of signal sources, etc. Our research is based on the convolution kernel compensation method (CKC), which is a blind source separation method. First, a correlation matrix of the recorded signals is estimated. Next, a measure of the global activity of the signal sources, called activity index, is introduced. The exact analytical model of the activity index variance was derived for the purpose of the estimation of the number of signal sources. Using the analytical model, the number of active signal sources can be estimated if some a priori marginal information is available!
. We evaluated these marginal parameter values in extensive simulations of compound signals. The number of sources, their lengths, signal-to-noise ratio, source triggerings, and the number of measurements were randomly combined in preselected ranges. By using the established marginal parameter values and increasing extension factors, the model of the activity index variance was deployed to estimate the number of signal sources. The estimation results using synthetic signal mixtures are very promising.

Abstract: Thermal spraying represents the process of obtaining new special multilayer structure materials, with good mechanical and chemical characteristics. These materials are often used in solving real important problems, like repairing worn parts working under severe wearing conditions or, ensuring efficient corrosion protection of parts used in sea, as platform, bridges, or obtaining high refractory surfaces. Most of the times, once obtained, these coatings need additional machining and, it is of interest to study how, and, if, any of the machining parameters do influence one of their very important characteristic, meaning, adherence to the basic substrate. The paper presents a study on the adherence of thermal sprayed coatings, obtained from some Romanian thermal sprayed materials and submitted to exterior cylindrical turning.

Abstract: The momentary maximum concentration of the most important air pollutants (nitrogen oxide, sulfur dioxide, carbon monoxide and dusts) was determined using the dispersion curves of the pollutants in the densely inhabited areas of Dâmboviþa County. In order to present the industry-wide potential impact of air pollutants on the population and on the environment, maps showing air pollution levels have been generated using gathered data and model calculations. Emissions data were retrieved through an intensive survey locating, characterizing and monitoring all important stationary sources. Weather and wind can result in exposures that occur in different locations from where the emissions actually occurred, and can create new pollutants due to chemical reactions in the atmosphere. There were used on-line collected meteorological and air quality data. Geo-applications were used to obtain Digital Elevation Models from the corresponding orthophotos through raster-vector conv!
ersion for each envisaged areas. Once an orthophoto has been prepared, the images displayed are spatially attributed (accurately mapped) and can be linked with any other data that is spatially attributed through geographic information system (G.I.S.). New information, collected from a combination of photo-interpretation, ground reconnaissance, and specific measurements, were layered on top of the orthophoto for easy reference. A Gaussian mathematical model allowed the calculation of the pollutants dispersion in air in order to estimate the environmental risk situations. The pollutant concentrations curves for various scenarios were overlaid on DEMs indicating the most exposed inhabited areas to pollutants. With the aid of measurements and scenarios, pollutant maps show the present and future air pollution situation in Dâmboviþa county with regard to various nocive substances. The results presented in this paper are obtained in the frame of the MEMDUR Project, which has as t!
he main objective to design, develop, test and implement in Dâmboviþa
County an advanced management system, which has to assure the evaluation of the environmental risk in order to administrate the crises situations.

Abstract: This paper proposes Genetic Algorithms (GAs) for path Autonomous Mobile Robot (AMR). This approach has an advantage of adaptivity such that the GA works perfectly even if an environment is unknown. First, we present a software implementation GA path planning in a terrain. The results gotten of the GA on randomly generated terrains are very satisfactory and promising . Second, we discuss extensions of the GA for solving both paths planning and trajectory planning using a Single Static Random Access Memory (SRAM) for Field Programmable Gate Array (FPGA). This new design methodology based upon a VHDL description of the path planning has the two (02) advantages : to present a real autonomous task for mobile robots, and being generic and flexible and can be changed at the user demand. The results gotten are promising

Title of the Paper: Path Generation for Autonomous Mobile Robot Navigation
Authors as they appear in the Paper: Ouarda Hachour
Email addresses of all the authors: kala_ouarda@yahoo.fr
Number of paper pages: 14
Abstract: this paper presents an algorithm for path planning to a target for mobile robot in unknown environment. The aim of this work is to develop an algorithm which allows a mobile robot to navigate through static obstacles, and finding the path in order to reach a specified target. We propose an algorithm that provides the robot a trajectory to be followed to move from the initial position to the specified target. The robot trajectory is designed in a grid-map form of a known environment with static obstacles. The robot moves within the unknown environment by sensing and avoiding the obstacles coming across its way towards the target. When this movement is done, it is necessary to plan an optimal or feasible path for itself avoiding obstructions in its way and minimizing a cost such as time, energy, and distance. The process of navigation must make the robot able to achieve these tasks : to avoid obstacles, and to make ones way toward its target.The algorithms are implem!
ented in visual basic and DELPHI programming language; whereby the environment is studied in a two dimensional coordinate system. The simulation part is an approach to the real expected result; this part is done using DELPHI with version 7, and visual basic. The algorithms permit the robot to move from the initial position to the desired position following an estimated trajectory.

Abstract: A promising alternative for remediating chloroorganic contaminants in groundwater is reductive dechlorination using Pd catalysts (e.g. Pd/Al2O3). The catalyst's high potential is, however, limited by its sensitivity to sulfide poisoning. The ubiquitous presence of sulfide in natural waters hinders the successful field application of Pd-based reactors for groundwater remediation. In the presented study, protective and regenerative measures for the catalyst Pd/Al2O3 against sulfide are presented. The protective approach includes oxidative water pretreatment using permanganate to remove sulfide (H2S/HS-) in water before it comes into contact with the Pd catalyst whereas regenerative approach introduces permanganate as oxidant for Pd-bound sulfide. Results showed that in the pretreated water sulfides were removed so that catalyst poisoning was prevented. This led then to a successful dechlorination reaction in the bulk phase. Experimental results also showed the high e!
fficacy of permanganate as oxidant for the catalyst-bound sulfides. This is most efficient when the regeneration of sulfide-fouled catalyst was conducted at low pH condition. Thus, a complete recovery of catalyst activity was obtained at shorter regeneration time (i.e. 30 min) using relatively low regenerant concentration of about 0.18 mM KMnO4. This study, therefore, present findings which are of high practical significance in terms of realizing the potential of Pd-based catalysts for environmental applications such as groundwater remediation.

Abstract: The article introduces the research of particles hydrodynamics in a cold flow model of FICFB biomass gasification process and its scale-up to industrial pilot plant. A laboratory unit has been made for the purposes of experimental research. The laboratory unit is three times smaller than the later pilot plant. For a reliable observation of the flow process, similar flow conditions must be created in the laboratory unit and the pilot plant. The results of the laboratory model will be similar to those of the actual device if geometry, flow and Reynolds numbers are the same. Therefore, there is no need to bring a full-scale gasificator into the laboratory and actually test it. This is an example of "dynamic similarity".

Abstract: this paper presents an algorithm for path planning to a target for mobile robot in unknown environment. The aim of this work is to develop an algorithm which allows a mobile robot to navigate through static obstacles, and finding the path in order to reach a specified target. We propose an algorithm that provides the robot a trajectory to be followed to move from the initial position to the specified target. The robot trajectory is designed in a grid-map form of a known environment with static obstacles. The robot moves within the unknown environment by sensing and avoiding the obstacles coming across its way towards the target. When this movement is done, it is necessary to plan an optimal or feasible path for itself avoiding obstructions in its way and minimizing a cost such as time, energy, and distance. The process of navigation must make the robot able to achieve these tasks : to avoid obstacles, and to make ones way toward its target.The algorithms are implem!
ented in visual basic and DELPHI programming language; whereby the environment is studied in a two dimensional coordinate system. The simulation part is an approach to the real expected result; this part is done using DELPHI with version 7, and visual basic.

Abstract: The electric arc furnaces are a very large power load, determining the negative effects on the power quality (harmonics currents, unbalanced load, and reactive power). For a maximum efficiency of the power consumption it is necessary to use an automat system for control the harmonics filters, the reactive power compensation installation and the electrodes position, in order to obtain a high value of power factor and a maximum efficiency. In this paper is used an adaptive algorithm for process control for an Electric Arc Furnace. The method is validating using simulation in PSCAD EMTDC software dedicated to Power Systems.

Abstract: Nowadays, there are lots of classic and alternative method that has been used to obtain and compute transfer function for a linear network. Although, problems still occur especially in the number of nodes, loops and simultaneous equations that need to be solved by this approaches. A proposed approach called NIRE (Network-Impedance Relationship Equation) will solve these problems by developing fixed equations for obtaining transfer function, rather than to extract its nodes, loops or simultaneous equations of its network. In this approach, the only required parameters are the network's impedance connections which will be taken from two sources which are from the input terminal and output impedance. The approach has been developed in an algorithm using software called MATLAB. It can be adapted in a computer-based application and also can be introduced as an alternative method in obtaining transfer function for educational purpose.

Email addresses of all the authors: kala_ouarda@yahoo.fr
Number of paper pages: 19
Abstract: This paper proposes Genetic Algorithms (GAs) for path Autonomous Mobile Robot (AMR). This approach has an advantage of adaptivity such that the GA works perfectly even if an environment is unknown. First, we present a software implementation GA path planning in a terrain. The results gotten of the GA on randomly generated terrains are very satisfactory and promising . Second, we discuss extensions of the GA for solving both paths planning and trajectory planning using a Single Static Random Access Memory (SRAM) for Field Programmable Gate Array (FPGA). This new design methodology based upon a VHDL description of the path planning has the two (02) advantages : to present a real autonomous task for mobile robots, and being generic and flexible and can be changed at the user demand. The results gotten are promising.

Abstract: People have many documents. For example, a variety of documents are prepared and used in public institutions. As the internet becomes widely available in recent years, paper documents are being replaced with electronic data, which are often distributed in the form of electronic data without being printed out. Similarly, in educational institutions, increasing number of documents are distributed in the form of electronic data. Such data are distributed through various routes and means, and prone to the risk of alteration in the process. Data may be protected against alteration, but it is difficult to completely prevent data alteration in the distribution process. Data can be generated with electronic signature that allows for the identification of data creator and possible alterations by third parties. This method is, however, not valid if the data becomes separated from the electronic signature, making the validation of data creator or data alterations difficult or!
impossible. In this paper, we describe the invention of a system that, even in cases where data is separated form the electronic signature, enables easy identification of possible data alterations by the electronic signature management. And we describe here an exploratory construction of private electronic notary service in university. We also add a review on the utilization method of private electronic notary service in universities.

Abstract: In this study the performance of a commercial air-breathing 100 W Polymer Electrolyte Membrane Fuel Cell (PEMFC) stack is experimentally and theoretically evaluated using a widely known commercially available generic mathematical model of the Transient System Simulation Software (TRNSYS). The simulation results were compared with the experimental data to investigate the convergence between them and to validate the model in order of establishing confidence in the model when used with rather small FC stacks. The PEMFC stack used in this project is a commercial product named H-100FC . The conclusions coming out of this study show that the simulation results are in good agreement with the experimental data and consequently this model can be reliably used to simulate sub kilowatt PEMFC s. A series of interventions for the improvement of the performance of this commercial PEMFC stack is proposed.

Abstract: The analyses of light gases in transformer oil provide the basis of a diagnostic evaluation of equipment health. Two new normalized methods which named characteristic normalization and mix normalization are presented in this paper. The Fisher rule to evaluate the results of the two pretreatment methods is also introduced. The evaluation of the results indicates that both of the two data pretreatment methods can achieve the purpose of big difference in the value of mean between classes and small difference in dispersion of a class. The DGA data of the failure transformers are treated by different normalization methods as the training samples, and then the samples are trained in the compound neural networks which use the CP algorithm. The diagnosis results of the test samples indicate that the new methods may help to improve the precision of network diagnosis.

Abstract: Abstract: -. The paper focuses on the analysis of characteristics of driving point impedance for a lossy gyrator. For a gyrator, the ratio between short-circuit input resistance and open-circuit input resistance is always greater then unity. The antireciprocity of the Hall transducer is a natural phenomenon and its results from investigation of transfer resistances. Is known that for a certain value of magnetic induction, in general, transfer resistances are not equal. In other words, Hall transducer is a passive non-reciprocal circuit. In certain circumstances, however, when Hall plate does have voltage zero, (constructively, electrodes are disposed on the same equipotential surface with zero inductance) transfer resistances are equal in value, but have opposite sign. In these cases we are talking about behavior of Hall transducer as antireciprocal circuit, respectively as a gyrator. Gyrators are a class of antireciprocal resistive two-ports. The findings are con!
cerning and the locus of the input equivalent impedance An assessment of Hall generator behavior regarded as a circuit element and particularly as a gyrator was performed by the means of experimentally validation Onsager-Casimir relation.

Abstract: The paper approaches some aspects regarding performances characteristics of gyrators with different circuit topology. The gyrators behavior of a class of two-ports structured on operational amplifiers and resistors is studied. In order to verify the theoretical predictions the analytical quadripolar parameters are bridged with the experimental one numerical by the means of a Pspice simulation. The gyrator equations express the instantaneous behavior of switching power converters, averaged over one switching cycle. Any dc-dc switching power converter meet the requirements of closed-loop control of output voltage or current. There are many ways to design a physical system with gyrator behavior like. Some gyrators are based on various physical effects, like the Hall-effect, other gyrators are created using electronically devices, like operational amplifiers. All these synthesis operate time-continuously.

The antireciprocity of the Hall transducer is a natural phenomenon and its results from investigation of transfer resistances. Is known that for a certain value of magnetic induction, in general, transfer resistances are not equal. In other words, Hall transducer is a passive non-reciprocal circuit. In certain circumstances, however, when Hall plate does have voltage zero, (constructively, electrodes are disposed on the same equipotential surface with zero inductance) transfer resistances are equal in value, but have opposite sign. In these cases we are talking about behavior of Hall transducer as antireciprocal circuit, respectively as a gyrator. Gyrators are a class of antireciprocal resistive two-ports. The findings are conc!
erning and the locus of the input equivalent impedance An assessment of Hall generator behavior regarded as a circuit element and particularly as a gyrator was performed by the means of experimentally validation Onsager-Casimir relation. Key-Words: - Hall transducer, antireciprocal, gyrator, two-ports.

Title of the Paper: A New Technique of Modeling Acoustic Echo with Blind Source Separation
Authors as they appear in the Paper: Amin Mohamed Nassar,Ashraf Mohamed Ali

Number of paper pages: 13
Abstract: We propose an integrated acoustic echo cancellation solution based on using multiple of small adaptive filters rather than using one long adaptive filter. A new approach is proposed using the concept of decomposing the long adaptive filter into low order multiple sub-filters in which the error signals are independent on each other . the independency of the error signals exhibits the parallelism technique. A novel class of efficient and robust adaptive algorithms. It exhibits fast convergence, superior tracking capabilities of the signal statistics. The proposed algorithm is also compared with multiple sub-filters approach used for acoustic echo cancellation as the technique of decomposition of error. It is generally found that adaptive LMS algorithm with lower order has faster convergence. In most of the cases, the eigen-value spread of the auto correlation decreases as the order of the filter decreases except for white input. we discuss also the complexity of our!
proposed design to show how our design has a good performance. Modern (FPGAs) include the resources needed to design efficient filtering structures. The modeling of the acoustic echo path was represented by using three sub-adaptive filters of order=10 with fixed step size =0.05/3 for each adaptive filter. We use sinusoidal input signal with additive white Gaussian noise (AWGN) which has different signal-to-noise ratio (SNRs) to examine our approach. The steady state error of our proposed technique is still high as the technique of decomposition of error. This steady state error is small with respect to using one long adaptive filter and this will be obvious in our simulation results. This paper addresses also the problems of blind source separation (BSS). In blind source separation, signals from multiple sources arrive simultaneously at a sensor array, so that each sensor output contains a mixture of source signals. Sets of sensor outputs are processed to recover the sourc!
e signals from the mixed observations.The term blind refers to the fa
ct that specific source signal values and accurate parameter values of a mixing model are not known a priori. Application domains for the material in this paper include communications, biomedical, and sensor array signal processing. Simulations are often needed when the performance of new methods is evaluated. If the method is designed to be blind or robust, simulation studies must cover the whole range of potential random input. It follows that there is a need for advanced tools of data generation. The purpose of this thesis is to introduce a technique for the generation of correlated multivariate random data with non-Gaussian marginal distributions for blind source separation technique.The output random variables are obtained as linear combinations of independent components. The covariance matrix and the first five moments of the output variables may be freely chosen. Moreover, the output variables may be filtered in order to add autocorrelation. The overall system is co!
mposed of echo with different sources of sounds ,first we separate all these sources using blind source separation then we use our proposed multiple sub adaptive filters approach for cancellation the unwanted sources.

Abstract: This paper investigates the technical feasibility of a system that could be used to collect the solar irradiation at high altitude, convert it into electricity, and then transmit it to the ground via a cable. As a first step to assess the viability of this device, an estimate of the solar irradiation that can be expected at a defined altitude above the ground is presented, based on real atmospheric data. The study demonstrates that locating PV devices at high altitude with the use of an aerostatic platform, could bring a significant advantage in the production of electrical power, if compared with a typical UK ground based PV system. The fundamental equations for a preliminary design of the system are presented together with a first realistic choice of the most relevant engineering parameters that need to be set. An estimate of the cost of the system is provided and the possible risks involved, applications, advantages and disadvantages of the technology are assess!

Abstract: We analyse the city buses time headway distribution and compare to the real time headway measurements. Since experimental data shows neither a smooth nor a random distribution, a mean--field theory with effects of traffic lights is developed to explain the peculiarity. It is shown that a smooth distribution can be modified significantly by the operation of traffic lights, and matches the experimental data characteristics well. It is therefor concluded that the posted time headway is of not much help for the passengers expecting the next bus at the bus stop.

Title of the Paper: Pollutant dispersion modelling for Portuguese river water uses protection linked to tracer dye experimental data

Abstract: Mathematical models are well known as useful tools for water management practices, directly or indirectly related to the implementation of the Water Framework Directive (WFD) in European countries. They can be applied to solve or understand either simple water quality problems or complex water management problems of trans-boundary rivers or multiple-purpose and stratified reservoirs. Accidental spills of pollutants are of general concern and could be harmful to water users along the river, becoming crucial to get knowledge of the dispersive behaviour of such pollutants. In this context, the mathematical modelling of dispersion phenomena can play an important role. Additionally, a judicious selection of mathematical models for application in a specific river basin management plan can mitigate prediction uncertainty. Therefore, intervention measures and times will be established with better reliability and alarm systems could efficiently protect the aquatic ecosystem!
s, the water uses and the public health. The main purpose of this paper is to evaluate the performance of river water systems dispersion modelling, based on tracer experiments data for calibration and validation. The present work describes the methodology used in the monitoring programs, basically consisting in the injection of a tracer dye (rhodamine WT) in an upstream river section and follow-up of the dye cloud along the river to determine the water dispersion behaviour in situ. The models were developed to simulate different water quality management scenarios on each reach of the three Portuguese rivers under study: Mondego, Douro and Tagus rivers. However, further developments are needed for Douro and Tagus rivers in order to simulate vertical and transversal dispersion processes and improve the model correlation with the experimental data. The models were calibrated and validated in order to produce operational tools used to estimate the probabilistic leading edge/pea!
k/tail times, the pollutant losses by volatilization, adsorption, prec
ipitation, etc. and remaining concentrations. These tools allows to define, for example, how long water intake need to be suspended after a pollutant spill and can be easily integrated in a future DSS, which should be developed and implemented by each one of the river basin management authorities. The good correlation between experimental and simulated data allows us to conclude that the applied models are accurate enough to describe and predict conservative pollutant transport under different hydrodynamic scenarios. This methodology is appropriate to assess the environmental impact of pollutant loads directly introduced into the streams and, subsequently, to define and implement the best water sources protection practices.

Abstract: As the growing amount of waste created by the construction industry poses severe environmental challenges, environmentally conscious construction processes have emerged as an issue of increasing importance for both the industry and society at large. The proper management of the construction and demolition waste, which constitutes the major solid waste stream in the European Union (apart from mining and farm waste) appears to be of great merit. Reverse logistics and waste management offer the appropriate contextual framework within which the problem can be tackled comprehensively. Towards this effect, a conceptual framework is presented on the current status and legislation in the field of construction and demolition waste management, as well as on the optimal deconstruction and demolition practices of the end-of-life buildings with the goals of materials' recycling and waste minimization. In addition, a novel integrated decision-making model for the entire construc!
tion and demolition supply chain is proposed starting from the deconstruction and demolition decisions till the transportation of the collected materials to potential recyclers/customers and waste disposal sites. Finally, we conclude with a demonstration of the application of the developed model is via a specific case study, and by discussing few interesting managerial insights.

Abstract: Hydrogen is industrially produced mainly from fossil fuels by the natural gas steam reforming, the coal gasification and as a by-product of the naphtha reforming. In the future, with respect of a lack of fossil fuels, hydrogen produced from water can play a very important role in the energy system. One of the way how to produce hydrogen from water are water splitting thermo-chemical cycles which replace thermal decomposition of water with several partial reactions. In the study, two most promising water splitting thermo-chemical cycles (Westinghouse cycle and Sulphur-Iodine cycle) were compared with two different processes for hydrogen production (coal gasification and coal pyrolysis). Results obtained from LCA of these processes are reported in the paper.

Abstract: In this study, technological developments and market tendencies in photovoltaic cell (PV) industry are investigated. The increasing energy demand and decrease in conventional energy resources orientates researches to be in tendency to continuously increase the output of alternative energy resources. Today, crystal silicon cells significantly dominate tendencies in PV Cell market with their converting outputs exceeding 20% in small areas. However, a PV panel with silicon crystal is very expensive. To increase output efficiency by decreasing costs of PV cells and modules, nanotechnology approaches are very important. Nanomaterials that used in PV cell production, absorb sunlight better, increase the energy transformation and cheaper than other materials but require special fabrication fixtures. PV cell market is dominated by Japan and Germany. Installation tendencies are become dense on grid-connected systems. Although the costs of PV module per watt generally follow!
a horizontal route, system installation costs decrease regularly.

Abstract: The solar energy is one of the most important energy sources available because, besides the fact that it is not polluting the environment and it helps to the reduction of green house effect, it is free of charge and it can be easily converted to other forms of energy. Clean and renewable energy production is getting more attractive due to global warming, environmental factors and decrease in conventional energy sources. Photovoltaic cells will be a good alternative against the conventional energy sources in the near future, with their decreasing costs and increasing efficiencies. Photovoltaic cells (PV) are exposed to a lot of various loads depending on their increasing usage areas. Among the energy expenses for a building, the lighting system can contribute up to 50% of the total electrical consumption, and especially large quantities of energy are used in schools and office buildings. For that reason lighting devices are important energy consuming units in our da!
ily life. In this study different load effects on PV cells are examined experimentally. D.C. and A.C. load behaviors are analyzed in switching and in steady state regime and their power-time curves are obtained for the demand of system power. Negative effects of the inverter circuit, which is used for feeding A.C. loads on the system, are expressed experimentally.

Abstract: In this paper, we employ gridded model for channel routing and place the terminals which are horizontally aligned. We have developed a two-layer channel router that can eliminate the constraints due to overlap. The proposed approach is suitable for cell/IP-based channel-less circuit with a few channels. Our developed tool can route the nets in nearly linear time achieving to the advantage of time to market, and lead to the area overhead of 6.34% increase in average. The area overhead results from the space insertion, and we also have shown that the proposed algorithm can achieve 100% routing on most ISCAS¡¦85 benchmarks. In addition, the number of channel tracks can be minimized by our algorithm. We proposed the star-routing algorithm for three layers channel routing using Manhattan-Diagonal Model to solve the channel routing problem. We drew up the smaller grid-model, and in order to avoid violating the DRC, so the algorithm has a restriction for the third metal-l!
ayer in routing step. We don¡¦t need to increasing extra spaces and moving any pins in order to finish the routing completely. The foregoing is good for hard blocks to finish the routing easily, and it does not replace the location of hard blocks because of routing incompletely. Therefore, the height of the entire routing channel can reduce a lot.

Abstract: A method to generate a quintic B-spline curve which passes through given points is described. In this case, there are four more equations than there are control point positions. Two methods have been developed to compensate for the difference between the number of unknowns and that of the equations. These are assuming that the curvatures at both ends of the curve are zero, and assigning four gradients to the given points. In addition to this method, another method to generate a quintic B-spline curve which passes close to given points, and which has the first derivative at these given points is described. In this case, a linear system will be underdetermined, determined or overdetermined depending on the number of given points with gradients. A method to modify a quintic B-spline curve shape according to the specified radius of curvature distribution to realize an aesthetically pleasing freeform curve is described. The difference between the B-spline curve radius o!
f curvature and the specified radius of curvature is minimized by introducing the least-squares method. Examples of curve generation are given.

Abstract: Parabolic dish solar concentrators are very expensive devices with a cost of up to a half of the total cost of a solar power station. The specific technology of parabolic mirror manufacturing makes the decrease of the cost very problematic. Even in mass production the cost of a parabolic mirror is estimated as $500 per square meter. There is another way to make a parabolic concentrator by approximating a parabolic surface with large number of small flat mirrors. We created a small prototype of this type of solar concentrator which contains 24 flat mirrors in the form of equilateral triangles with side length of 50mm. This prototype has special nuts to adjust the positions of the nodes in the points of connections of the apexes. These nuts make it possible to approximate the parabolic shape in an easy and inexpensive way.

Abstract: The paper analyzes the close-circuit Brayton (Joule) cycles for High Temperature Gas (Helium) cooled nuclear Reactors (HTGR). Analyzed cycles are with Regenerative Heat Exchanger (RHE), Fragmented Compression and Inter-Cooling (FC&IC). The HTGR imposes the working agent and hot source¡¦s parameters. The cooling conditions give the cycle¡¦s minimal temperature. In the 1st paper¡¦s section, for ideal processes cycles, we show that: A) the boundary parameters and design schemes inflict: A1) the compression ratios (ƒÕ), A2) the specific net work per 1 kg He (wnet), and A3) the thermal efficiencies (£bth); B) the performances are increasing with the IC¡¦s number. In the 2nd section we are taking into consideration the irreversibility¡¦s factors (temperature difference at RHE, revolving machines isentropic efficiencies, and pressure drops) doing sensitivity analyses about their influences on real processes cycle¡¦s performances. We show that: 1) cycle¡¦s performances are!
not continuous growing with IC¡¦s number, and 2) the main influences on design¡¦s option are given by: 21) the temperature difference at RHE and 22) the pressure drops. In the 3rd section we adjusted all the quality factors in a similar manner, reducing the irreversibilities, showing the synergic influences. The 4th section relaxes the hot source¡¦s restrictions. It analyses the influence of HTGR output / input temperatures variation on the main thermodynamic data, showing: £\) the benefit of maximal temperature increase and £]) the need to correlate HTGR¡¦s temperature increment output vs. input with the maximal temperature. The final section contains the main conclusions of the paper.

Abstract: In this paper we consider a modified model of an Alpazur oscillator with a periodically switching operation. Complex oscillatory phenomena are observed due to both switching operation and the appearance of an additional nonlinear component in circuit model. Indeed, subharmonic oscillations and chaotic behavior are illustrated. In addition, time series, phase trajectories and power spectrum was examined in the analysis of the system dynamics. The transition to chaotic states through doubling period bifurcation cascade and the direct transition from fundamental harmonic or odd subharmonic orbits and transition from a special bifurcation paths to chaotic states are discussed in the state space. The role of higher harmonic spectral lines in period-1 responses under parameter variation have seemingly similarities with the results obtained in previous works for non switched dynamical system. Chaotic states resulting from different transition modes are also presented in t!
his paper. For the numerical simulations, techniques for deriving time and composite Poincar´e method are applied.

Title of the Paper: A Novel Control Strategy for Dynamic Voltage Restorer using Decoupled Multiple Reference Frame PLL (DMRF-PLL)

Abstract: This paper presents a new control scheme for dynamic voltage restorer (DVR), which consists of a set of series and shunt converters connected back-to-back (BTB), three series transformers, and a dc capacitor installed on the common dc-link. The DVR is characterized by installing the shunt converter on the source side and the series converter on the load side. A decoupled multiple reference frame phase-locked-loop (DMRF-PLL) is proposed, which decouples signals of different frequencies and eliminates interactions between the fundamental-frequency positive-sequence components and harmonic and/or negative-sequence components in the grid voltages. The proposed DMRF-PLL scheme achieves a fast, precise, and robust positive-sequence voltage detection even under unbalanced and/or distorted grid voltages conditions. A detailed description and derivation of the detection method is presented. Besides, a separate proportional-integral (PI) controller is adopted to regulate the!
dc-link capacitor voltage. The load voltage waveform is restored to be sinusoidal with fundamental frequency by dynamically injecting compensating voltages to the series brunch of converters. The validity and effectiveness of the presented scheme has been confirmed by extensive simulation results obtained from a 380V/50kVA system using Matlab/Simulink.
Keywords: Dynamic voltage restorer, decoupled multiple reference frame phase locked loop (DMRF-PLL), voltage sag detection, dc capacitor control, series converters, shunt converters, harmonic and unbalanced voltage compensation.

Abstract: A remote location in the northeastern part of Naxos Island, Greece, has been investigated with respect to wind power potential, using real data collected from a measurement mast. The obtained wind characteristics were statistically analyzed using the Weibull and Rayleigh distribution functions. The results from this investigation showed that the selected site falls under Class 7 of the international system of wind classification as the mean annual wind speed recorded in the area was 7.4 m/s and the corresponding annual mean power density was estimated to be 420 W/m2. Furthermore, the prevailing wind directions characterizing the area were the northeastern and the north-northeastern. From the statistical analysis of these results, it was revealed that the Weibull model fitted the actual data better. This remark was further enhanced by the evaluation of the performance of these two distributions. Finally, the expected energy production from two potentially installed !
wind turbines of 1 MW and 2.5 MW has been determined, based on the available wind potential. The resulting annual energy production is 4 GWhe and 8 GWhe for the wind turbine of 1 MW and 2.5 MW respectively.

Abstract: The proposed mathematical model is a numerical method to find the temperature distribution at metals processing with concentrated laser beam, assisted by an active gas jet. The quality and effects of laser beam processing depend on: optimal choosing of the irradiation parameters, characteristics of the processed material surface, additional gas, parameters of the focalization system etc and setting up an optimal processing regime by choosing and maintaining these optimal values during the whole irradiation process as well. The first part of this paper deals with the differential equations system, which governs the laser processing of materials in the presence of the O2 jet, occurring on the mobile irradiation. The numerical method of solving the mathematical model is presented in the second part of the paper. It will base the solving of mathematical model equations, with the advantage of a better approximation of the real phenomenon by considering the simultaneous !
existence of the solid, liquid, and vaporization states in the material zone interacting with laser beam. The defocusing effect of laser beam simultaneous with its advancement in material and the energy loss by electromagnetic radiation and convection will be taken into account as well. The last part of paper presents the graphical representations of radial distribution of the temperature of the three phases: solid, liquid and vapors, and the obtained numerical results, which allow the determining of the technological parameters of processing and the material constants.

Abstract: Models of radio channel propagation are indispensable in the analysis and design of wireless communication systems. They are used to predict power and interference levels and analyze other properties of the radio link. The main goal of this work is to present a tool that we have developed subject to characterize and modelling indoor radio channel propagation. The tool is based on the ray tracing technique (RTT). This, is used to predict the propagation of HF electromagnetic waves. As, in realistic environment we cannot neglect the significant impact of Human Body Shadowing and other objects in motion on indoor 60 GHz propagation channel. Hence, our proposed model allows a simulation of propagation in a dynamic indoor environment. First, we describe a model of human body. Second, RTT with this model is used to simulate the propagation of millimeter waves in the presence of persons in motion. Results of the simulation show that this tool gives results in agreement wi!
th those reported in the literature. Specially, the effects of people motion on temporal channel properties. Other features of this approach also are outlined.

Abstract: The Earth's ionosphere plays a crucial role in Global Positioning System (GPS) accuracy because this layer represents the largest source of positioning error for the users of the GPS after the turn-off of Selective Availability (SA). This paper studies the ionospheric effect on transionospheric signal propagation for the Earth-satellite path using 3D Jones Ray-Tracing utilizing Nelder-Mead optimisation algorithm. The ionospheric delay or advance is obtained from the difference between the distance of the ray path from the satellite to the receiver determined from the ray-tracing and the distance for propagation over the line of sight (LOS) at the velocity of light in vacuum. The difference between the standard dual-frequency models corrected range and LOS, known as Residual Range Error (RRE) is calculated. Results show that the RRE of group delay value is different from RRE of phase advance. On the other hand, the group and phase path is longer when considering the!
geomagnetic field effect on both GPS frequencies L1 and L2. The higher order term in total electron content (TEC) calculation that relates to the refractive index is normally neglected due to its small value, but it is clearly shown that it does have some effects in ray-tracing. This analysis needs to be considered for more accurate GPS range finding.

Abstract: This paper presents a new analysis of friction and heat transfer in the slip flow boundary layer at constant heat flux boundary conditions for both liquids and gases. By using similarity solution, the fundamental equations of the boundary layer are transformed to ordinary differential equations containing a prandtl number. These ordinary differential equations are solved numerically by using a fourth order Runge-Kutta and shooting method. Consequently, the velocity profiles, temperature profiles, the wall shear stress and the local Nusselt number exhibit a dependence on the slip coefficient. It is shown that laminar boundary layer with slip flow can sufficiently reduce wall friction through slip flow conditions for both cases and increase heat transfer rate in liquids at constant heat flux boundary conditions.
Keywords: constant heat flux, horizontal surface, slip flow, wall shear stress, Nusselt number.

Abstract: Wind energy has been used for navigation and agriculture. Recently, wind energy is given a lot of attention because of the focus on renewable energy. Wind energy growth in Asia is currently on the rise. Both India and China are leading with more installed capacity and manufacturing facilities. In Malaysia, wind energy conversion is also given a serious consideration. The potential for wind energy generation in Malaysia depends on the availability of the wind resource that varies with specific location. This paper deals with how to model or how to fit several probability distribution models to Malaysia wind speed data available. As usually described in the literature concerning efforts to develop an adequate statistical model for wind speed, there are a few statistical models discussed such as Weibull Distribution and Rayleigh Distribution. In the literature, it is a common procedure to compare these functions to determine which one fits the measured distribution be!
st. The result from a simple descriptive statistics shows that Weibull distribution might be the probability distribution that can fit the data well.

Abstract: Image registration and fusion are conducted using an automated approach, which applies the automatic adaptation from frame to frame with the threshold parameters. Rather than qualitative approach, quantitative measures have been proposed to evaluate outcomes of retina image fusion. Concepts of the discrete entropy, discrete energy, relative entropy, mutual information, uncertainty coefficient and information redundancy have been introduced. Both the Canny edge detector and control point identification are employed to extract retinal vasculature using the adaptive exploratory algorithms. The shape similarity criteria have been selected for control point matching. The Mutual-Pixel-Count maximization based optimal procedure has also been developed to adjust the control points at the sub-pixel level. Then the global maxima equivalent result has been derived by calculating Mutual-Pixel-Count local maxima. For two cases of image fusion practices, the testing results are !
evaluated on a basis of information theories where the satisfactory outcomes have been made.

Abstract: Some practical approaches have been presented successfully, which can be applied for control engineering education. Compared with conventional lecturing and laboratory exercising, instructing outcomes can be improved significantly. Two independent sets of instruments from Feedback Instruments Limited are selected to conduct experiments on a basis of the fundamental control theories. In particular, the 33-110 servo system is selected, consisting of three components: mechanical unit, analogue unit and digital unit. The 150 servo system contains a number of major discrete component units. Both systems can be used to test the fundamental control principles, such as the PID control. Matlab is employed for data analyzing, simulation, plotting and programming. Simulink is also employed to implement numerical simulations for advanced control practices. For practical control problems in real time, such as robotic control and engine control, Labview can be applied considerin!
g its merits of the graphical user interface design and block diagram approach. Some typical examples to improve classes at the system and control laboratory are presented, using software or hardware instructing tools such as the Matlab, Simulink and Labview.

Abstract: Abstract: A simple span T-beam bridge was analyzed by using AASHTO specifications and Loadings as a one dimensional structure, then a three- dimensional structure was carried out by using finite element plate for the deck slab and beam elements for the main beam. Both models were subjected to 1.5 AASHTO Loadings and at the same locations to produce maximum bending moment and maximum shear. The results were analyzed and it was found that the results obtained from the finite element model are smaller than the results obtained from one dimensional analysis, which means that the results obtained from AASHTO loadings are consecutive

Abstract: Water restrictions are currently in place in most of the major cities of Australia in response to the severe drought. In order to manage water resources in a sustainable manner and to help reduce the restrictions, developing methods to recycle and reuse the stormwater and effluent water/waste water has become an important and urgent issue. This paper presents a review of the available stormwater treatment and reuse techniques and introduces a new technology known as 'Green Gully' that collects, purifies and reuses stormwater throughout an automated network system. The component of Green Gully along with experimental set-up and procedures are described. Preliminary experimental result on performance of Green Gully is provided and discussed. A comparative study of available treatment measures with respect to advantages, disadvantages and pollutant trapping efficiency is presented and discussed. This paper also highlights the current stormwater reuse techniques to red!
uce the water crisis. Conclusions based on a comparative study of stormwater treatment measures and reuse techniques are presented, which will be useful for stormwater researchers, planners and stormwater management in general.

Abstract: According to the literature assigned to automatic target recognition (ATR) system theory, one of the most important methods to improve the performances of these is to use multispectral information provided by a suitable set of sensors, and certainly, proper information fusion techniques. In this paper authors propose an application using an improved evolutive version of Sugeno's fuzzy integral to increase the target recognition performances based on high-resolution radar (HRR) and video imaginary. In order to confirm the broached theoretical aspects, a real input database was used.

Abstract: The purpose of this paper is to address the multi-objective optimization via combined fuzzy satisfied method and evolution programming (E.P.) method. The concept of non-inferiority is employed to characterize a solution of the multi-objective problem. Then, a fuzzy satisfied method based on evolutionary programming is introduced to determine the optimal solution. As a result, the objective functions of the optimization problem are modelled with fuzzy sets to represent their imprecise nature. That also enables us to reduce the inaccuracies in decision-makers¡¦ judgments. A time-sharing computer program is implemented, and an application to a multi-objective operation problem in feeder reconfiguration in electric power systems is demonstrated along with the computer outputs. In conclusion, the proposed solution algorithm allows for a more realistic problem formulation efficiently obtained the optimal solution for the tested system with a large search space.

Title of the Paper: Noise-induced bottleneck in transportation
Authors as they appear in the Paper: Ding-wei Huang
Email addresses of all the authors: dwhuang@phys.cycu.edu.tw
Number of paper pages: 10
Abstract: It is well known that noise reduces the efficiency in transportation. However, what is not so well known is that a small variation of noise can sometimes trigger an abrupt change to the whole system. In this paper, we report such a phase transition induced by the variation of noise. We study the influence of stochastic noise in asymmetric simple exclusion processes in the presence of an on-ramp. Two types of bottleneck can be induced by the noise. With a small noise, a light bottleneck is observed as traffic jams emerge intermittently around the on-ramp. With a large noise, a heavy bottleneck is observed as the traffic in the upstream becomes severely congested. An abrupt transition separates these two types of bottleneck effects. We obtain the detailed phase diagram, which summarizes all the possible states. The density profile, headway distribution, and spatial-temporal trajectory are discussed. We also comment on the daily experiences on highway traffic.

Abstract: The combined effects of ionizing radiations (electron beams of 5.5 MeV) and non-ionizing radiations (microwaves of 2.45 GHz) on the inactivation of total number of germs (TNG) and moulds in depreciated food such as wheat bran, wheat flour and minced beef are presented. The following types of treatments were performed with electron beams (EB) and microwaves (MW): separate EB irradiation, separate MW irradiation, successive irradiation (EB irradiation followed by MW heating) named (EB+MW), successive irradiation (MW heating followed by EB irradiation) named MW+EB and simultaneous irradiation with EB and MW named S(EB+MW). The first interesting experimental result is that the microorganism's survival fraction diminishes exponentially with EB dose for the separate EB irradiation while for the separate MW irradiation the microorganism's survival fraction exhibits an oscillatory decrease versus MW dose: periods of microorganism inhibition are followed by periods of micro!
organism stimulation. The second important result is that all combined irradiation procedures such as S(EB+MW), followed by MW+EB and then by EB+MW, cause greater reduction of NTG and mould survival fractions than separate EB irradiation or separate MW irradiation. The S(EB+MW) treatment type produces the maximum reduction of NTG and moulds. The third important result is that the EB dose level could be reduced by a factor in the range of 1.5-2.5 by combined EB and MW irradiation.

Abstract: The paper presents the test results obtained for SO2, NOx and VOCs removal at semi-pilot scale by combined electron beams (EB) and microwaves (MW) induced non-thermal plasma processes, named EB+MW-NTP. Also, it is described a demonstrative installation consisting of an EB source of 1.8 MeV and 10.8 kW, a microwave source of 2.45 GHz and 4.2 kW and a reaction chamber of 1.102 m x 0.73 m x 0.243 m inner dimensions, in which are injected both, EB and MW. For VOCs removal is used combined EB+MW-NTP and catalytic oxidation, named EB+MW-plasma catalysis, by introducing a catalyst bed at the bottom end of the reaction chamber. The high power EB and MW sources are able to activate the catalyst without additional heat supply. The EB+MW-NTP process, compared with separate EB-NTP or separate MW-NTP process, provides higher pollutants removal efficiencies. The results suggest that chemical reactions driven in both types of plasma, EB-plasma and MW-plasma, complete and sustain!
each other at a higher rate level in the case of pollutants treatment by EB+MW-plasma.

Abstract: Abstract: The artificial neural networks (ANN) have proven their efficiency in several applications: pattern recognition, voice and classification problems. The training stage is very important in the ANN's performance. The selection of the architecture of a neural network suitable to solve a given problem is one of the most important aspects of neural network research. The choice of the hidden layers number and the values of weights has a large impact on the convergence of the training algorithm. In this paper we propose a mathematical formulation in order to determine the optimal number of hidden layers and good values of weights. To solve this problem, we use genetic algorithms. The numerical results assess the effectiveness of the theorical results shown in this paper and computational experiments are presented, and the advantages of the new modelling.

Abstract: During the last decade, metaheuristics have become increasingly popular for effectively confronting difficult combinatorial optimization problems. In the present paper, two individual meatheuristic algorithmic solutions, the ArcGIS Network Analyst and the Ant Colony System (ACS) algorithm, are introduced, implemented and discussed for the identification of optimal routes in the case of Municipal Solid Waste (MSW) collection. Both proposed applications are based on a geo-referenced spatial database supported by a Geographic Information System (GIS). GIS are increasingly becoming a central element for coordinating, planning and managing transportation systems, and so in collaboration with combinatorial optimization techniques they can be used to improve aspects of transit planning in urban regions. Here, the GIS takes into account all the required parameters for the MSW collection (i.e. positions of waste bins, road network and the related traffic, truck capacities, !
etc) and its desktop users are able to model realistic network conditions and scenarios. In this case, the simulation consists of scenarios of visiting varied waste collection spots in the Municipality of Athens (MoA). The user, in both applications, is able to define or modify all the required dynamic factors for the creation of an initial scenario, and by modifying these particular parameters, alternative scenarios can be generated. Finally, the optimal solution is estimated by each routing optimization algorithm, followed by a comparison between these two algorithmic approaches on the newly designed collection routes. Furthermore, the proposed interactive design of both approaches has potential application in many other environmental planning and management problems.

Abstract: In this paper a new approach is presented for key management access and sharing secret keys between certified users of a group. Such schemes are referred to as Symmetric Key Management Systems. The concept of information lifecycle management is first presented and analysed in the context of data storage efficiency. This concept is then extended for use with the management of symmetric secret keys. The need for a standard in symmetric secret key management is presented and founded on software engineering principles. A novel scheme contributing in this direction is hence presented. Specifically, access controls processes are presented that are based on passwords. These passwords, with the additional use of the AES cryptographic algorithm and nonces can be used to provide not only authentication for the access control in the system but additionally for the access in the encrypted file that stores all the symmetrical secret keys of each user of certified group. Followi!
ng this, a new approach for the lifecycle management of secret keys is presented in order to achieve the secure communication based on encryption - decryption of all the messages in real time with the simultaneous use of two symmetrical secret keys for each transmission of information between the users. It is finally concluded that this innovative technology guarantees the automatic password and secret keys management lifecycle irrespective of the actions of the users and provides secure communication between certified group of users in local network and in internet.

Abstract: In this paper model for managing the Job Rotation of personnel attached to specific military units is proposed. This model aims to maintain the level of the overall preparedness of the units against known risks, by maintaining the presence of skilled personnel present in the unit at any time. The model is used for the development of a software tool that manages the systematic training of army officers in risk prevention and crisis management. The aim of this tool is to globally optimize the movements of army officers between units and training centers so that no units are ever left without skilled staff trained for a particular type of contingency. While officers are in training, they prepare for new hazards and prepare emergency plans for dealing with these particular hazards with the support of more experienced trainers or mentors. When this rotation ends, officers return to their units and assume responsibilities in both implementing the plans they have helped c!
reate, as well as in disseminating the knowledge and skills they have acquired and training more of the unit's staff in being able to conduct appropriate parts of the newly introduced emergency procedures.

Abstract: Security in digital transmission is an increasingly interesting topic in a number of fields. In many cases however, the need for security is forfeited due to the high complexity of commonly used cryptosystems. The use of the underdetermined source separation problem as a basis for a cryptographic mechanism has recently been proposed. Many cryptographic algorithms, such as public key algorithms which based a common military application, use as a basis intractable number theory problems (such as integer factorization and exponentiation). Underdetermined blind source separation is also shown to have the potential to serve this purpose, as the difficulties of deriving an analytic solution to this problem have been extensively documented. This paper presents a study of blind source separation based encryption, proposes some further improvements in approaches that have already been presented and illustrates the application of the improved algorithms in the paradigm of se!
cure speech communication. The proposed scheme is related to Independent Component Analysis Concepts. A preliminary cryptanalysis study is presented that verifies the adequacy of the new scheme for use in mobile military communication units and other applications where security is critical. The proposed scheme is also shown to be immune to some of the attacks to which existing methods were believed to be vulnerable.
Keywords: Blind source separation, encryption, secure digital communications.

Title of the Paper: Coding of Checksum components for Increasing the Control Reliability of Data Transmission for Military Applications
Authors as they appear in the Paper: Nikolaos Bardis

Abstract: Computer Systems used in Military and other challenging applications, are often exposed to increased levels of electromagnetic radiation. Embedded systems falling in this category often suffer from this exposure due to the operation of the device to which they belong. Consequently data communications within such devices need to be protected against transmission errors. Current general purpose encoding schemes that are used in other communication applications are prohibitively complex for this application. In this paper an innovative extension to the well known checksum concept is proposed that is capable of controlling errors in intra device data transfers. The new technique is shown to be simple enough for implementation and to increase the probability of detection of errors by several orders of magnitude. The scheme is hence shown to be suitable for embedded computing platforms for military and other demanding systems. More specifically, the modified checksum is !
examined in respect of its suitability for use in schemes for the transient error detection in schemes for reliable data storage within computing systems and it is explained why it is extremely suitable for this application. The modified checksum is also considered in the context of algorithm based fault tolerance schemes and it is again concluded that it can contribute to the overall scheme efficiency and effectiveness. The modified checksum is hence shown to be an algorithmic tool that can significantly contribute to the design of reliable and fault tolerant computing systems, such as the ones used for military systems or other applications that operate in adverse environments.

Abstract: In this article, a study is presented that aims at the development of a prototype system for the secure real-time exchange of messages between users of workstations connected to the same TCP/IP network. The security is provided based on the AES prototype cryptographic algorithm. An advanced key management scheme is used within this system that enhances the security of the system, reduced the effects of possible security breaches and simultaneously hides from users the unnecessary complexity related to handling multiple encryption keys. The scope of application is military units and is intended to become the basis for the design and development of an integrated framework for the exchange of secure messages between different sites of military or other organizations that are concerned about information security. The present design is limited in its application to local area networks only. There are however no fundamental restrictions and an expansion to wide area netw!
orks and the internet is also possible. The design of the application is firstly presented. Problems of security and ease of use that are related to the management of the secret encryption keys are explained. A solution is hence presented for these problems, that is based on an innovative scheme for key storage and management. The design and implementation of the application is presented in detail along with description of its basic functionality. The plans for application and further development of the application are described and conclusions are finally drawn.

Abstract: This paper investigates the issue of real time simulations using MATLAB as a tool. Real-time systems are loosely defined as the class of computer systems that interact in a time frame defined by the external world. It is an environment where a single computer is a host and a target. After creating a model and simulating it with simulink in normal mode we can generate executable codes with real time workshop. Here we have used MATLAB as an application tool which provide us the specialized tool boxes for specific areas. The real time window target communicates with the executable program acting as a control program and interfaces with the hardware device through the I/O port. Here we tried to analyze a magnetic levitation system. The control goal is to suspend a steel sphere by means of a magnetic field counteracting the force of gravity and to be able to apply a controlled disturbance to force the sphere to follow a predetermined trajectory. The control to be app!
lied is the voltage, which is converted into a current via internal circuitry in the controller located in the mechanical unit. The current passes through and an electromagnet which creates a magnetic field in its vicinity. The sphere is placed along the vertical axis of the electromagnet after the control system is started in the software. In this way a approach towards real time workshop is analyzed and applied.

Abstract: In this paper we introduce a fast algorithm that can detect the most unusual part of a digital image. The most unusual part of a given shape is defined as a part of the image that has the maximal distance to all non intersecting shapes with the same form. The method is tested on two and three-dimensional images and have shown very good results without any predefined model. The results can be used to scan large image databases, as for example medical databases.

Abstract: abstract :- Voided slab bridge deck composed of two continuous span is 17.3m Long and 16m width with all over depth of 0.9m. The voided slab is composed of 20cm top and bottom slabs with circular voided areas of 50cm in diameter and center to center of these circles of 75cm. The locations of AASHTO loadings are positioned at certain points of deck slab to give maximum positive and negative shearings. These locations are determined from one dimensional model. The analysis of the bridge deck is carried out by two approaches. The first is AASHTO specifications where one dimensional approach is adopted and the second is three dimensional approach where finite element analysis is considered. The maximum shears obtained by both methods are found to be in good agreement with negligible differences.

Abstract: This paper addresses the problem of conventional FFT/IFFT problem in high speed applications. When the number of data points are the power of four at that time it is wise able to use radix-4 algorithm instead of using the conventional radix-2 algorithm. Here a 16 point radix-4 IFFT algorithm is taken into consideration. It offers fewer multiplications than the processors using radix-2.Number of stages are also minimum in comparison to the other. A novel and simple architecture of this IFFT algorithm is presented. It includes pipelining and parallelism in together. With the concurrent use of pipelining and parallelism the advantages of minimization of latency time and the increment of the throughput rate can be achieved. This architecture incorporates Radix-4 CORDIC which provides almost multiplier less architecture. The whole radix-4 CORDIC based radix-4 IFFT architecture is implemented on a FPGA device at operating frequency of 50 MHz with the accuracy up to 32 !
bit precision. Only 43% of the total area is consumed by the implemented architecture

Abstract: The present paper will investigate adaptive reuse and sustainability of existing buildings and historic ones by having special consideration for Iran's climate change. In this paper we take it to mean the strengthening, changing, or improving the existing facilities such as those facilities meeting with current performance requirements necessary for their intended use. We show that adaptive reuse and rehabilitation of existing structures and historic ones should be a central strategy for creating a sustainable environment which meets with human needs while maintaining the natural environment in a healthy and useful state. Drawn conclusions would provide guidelines for sustainable rehabilitation projects. The main concentration will be on reusing of the adapted historic buildings in order to make them more Sustainable and as a result to reduce the climatic change impacts in Iran.

Abstract: The administration and management of a farmer¡¦s associations are governed by Farmer¡¦s Association Act and Regulations of Credit Division of a Farmer¡¦s Association to ensure a solid and solvent management of a farmer-oriented financial institution, guarantee the benefits and privileges of account holders, and promote the economic development and prosperity of the communities for farmers and fishermen. This study intends to explore the correlation among personality traits, leadership competence and organizational performance. The methods include data envelopment analysis and structural equation modeling. The findings suggest that the leader¡¦s charisma demonstrated by the chief executive director serve as an important intermediated variable for affecting the performance of the management of Farmers¡¦ Association and propose suggestions for the management. The indicators of personality traits of chief executive directors in a farmer¡¦s association should be taken !
into consideration in the election of a chief executive director. As well, the indicators of leadership competence of chief executive directors in a farmer¡¦s association should be taken into consideration in the election of a chief executive director.

Abstract: Local utilities face new challenges under changing conditions of the energy sector by the application of decentralized energy management systems which strongly depend on information of the grid state. Due to distribution grids are not entirely observed missing data has to be approximated i.e. using load profiles. Furthermore, future distribution grids have to offer system services similar to transmission systems and thus reactive power profiles are strongly needed for demand management, stability concerns and cost optimization. In this paper a method to determine load profiles based on measured time-series is introduced as well as eleven independent reference profiles of reactive power of classified load types. In combination with existing active load profiles the gained information shall be used for state identification of underdetermined grids, to support energy management systems and to forecast load demands.

Abstract: The plate-type electrostatic precipitators have long been used by industry applications as the preferred method for controlling pollution with dust particles. The paper analyze the collection efficiency, for electrostatic precipitators with three sections (still, there is in industry applications), when are used different voltage supplies of electrostatic precipitators sections, the gas particles mass distributions, element average V-I curves, onset Corona voltage, spark discharge voltage, current density, collection efficiency, the inlet and the outlet dust concentration for different energization of sections. It's been performed an analysis of the total harmonic distortion coefficient of the current absorbed by the source, the supply voltage, the apparent and active power (for fundamental and harmonics), and the power factor (global, fundamental's and deforming) in situation when the current's value from the ESP field was superiorly limited.
