Abstract: Abstract: Nowadays XML documents are prezented into the Web more than ever. Using XLink hyperlinks, a document can refer different portions of information in different documents into the Web. With XLink hyperlinks the XML documents in the Web can be investigated from querying point of view not just while browsing these documents. There are few implementations regarding XLink recommendation and just two implementations regarding quering XML documents using XPath/XQuery expressions in presence of XLink hyperlinks. On the other side XPath/XQuery has many implementations and wide support from IT leaders in the world. In this paper it is shown another way of using XPath/XQuery to query XML documents in presence of hyperlinks. The paper shows a model and its implementation. To materialize the new model it is used Saxon-B processor, with which was created an extention named BOTA. Prototype BOTA can be used in different web applications and easly can be integrated into Web!
Services in order to select something more narrow that the whole XML document. The prototype Bota especially can be used in applications with RSS and Atom.

Abstract: The purpose of HVAC appliances is to provide a comfortable environment and set the conditions for efficient work. The enhancement of buildings' energy performance puts emphasis on meeting the comfort requirements indoors, as the acceptable environments have to be provided from less energy. The comfort of the occupant is determined by the heat exchange between his body and his indoor environment. There are four local discomfort parameters that may cause discomfort on certain body parts even if whole body thermal comfort conditions are met. To help the modelling of thermal comfort conditions in buildings, on one hand we investigated, through human subject experiments, the combined effect of two discomfort parameters that are simultaneously present in the indoor space. Another modelling method is introduced in the second part of the paper where we show the results of CFD modelling of possible discomfort caused by natural ventilation required for air supply of gas appl!
iances.

Abstract: Abstract: - In the previous years the environmental consciousness of the society has become stronger also in Hungary. The bottleneck of this process is the lack of public information on environmental data. The Institute of Environmental Engineering, University of Pannonia has undertaken the challenge to develop an online environmental information system. This system is able to receive and process the collected environmental data via Internet. The aim of project to define physical and chemical parameters of surface waters and to support the hydro-geochemical elements of the typology with the analysis of the main ions and to the streams for pollution and apply Water Framework Directive (WFD) for examined water bodies further goal is to display result analysis via internet in Environmental Information System by its authors. In the first phase of mapping surface waters Hungarian streamlets were charted. Streams were categorized according to typology. The field measurem!

Measured results have been compared with MSZ 12749 standards and accordingly streams were classified. Bedrock has taken effect via main ions of the water so this element of the typology has been proved by main ions. In the case of N and P forms only polluted sites were significantly different. On the homepage bar charts show measured values at different sampling sites of the streams. On the Google Map distances between two sampling sites were coloured according to water quality colour scale. The developed homepage contains such a techniques of visualization that makes, it easily understandable for everybody

Abstract: The purpose of our research is to find algorithms for loading large maps on PDA and place on it the geographical location given by latitude and longitude. C++ and C# programming languages have been used for implementation. It was elaborated a software which runs on PDA with Windows Mobile 2003 OS and implements algorithms for finding the coordinate on a map represented like a TIF image. The application must localize the coordinates known by longitude and latitude over a given image in TIF format which can represent a map with scale 1:200000 or 1:25000. The map headers contain information that refers to map limit. An algorithm that permits map synchronization when the value of current map is out of limit it was necessary.

Abstract: In this paper, an evaluation of the network routing algorithms is presented. Problems that arise in routing are treated, each envisaged in different scenarios in order to obtain a result in comparing different topologies. The comparison analysis is pursuing obtaining a result over the performance of the network. In order to measure performance, the costs of a network and the delays are aimed. After that, the topology effect is presented. In matter of performance, topology and blocking problems are strongly related. Therefore an analysis of the blocking probability is also presented. As conclusions, solutions for the presented scenarios and also for other important scenarios are given. In all these algorithms the time problem was not yet consider until now, so the average execution time is finally analyzed.

Abstract: In office buildings occupants do high intensity intellectual work in eight hours. Quality and quantity of completed tasks are elementary influenced by indoor comfort, particularly thermal environment and indoor air quality. Investigation of indoor air quality has brief history, although it is getting more important issue nowadays. At Department of Building Service Engineering and Process Engineering, research work has been carried out as industrial assignments as well as tenders, sponsored by Hungarian Scientific Research Fund. For indoor air quality examination a laboratory state has been developed. Several materials have been evaluated concerning emission rate and its effect on indoor air quality. In the course of research, naive panels have been adopted, using Fanger (-1;+1) and Hedonic scale. Improved indoor air quality require increased fresh air rate, hereby energy demand of building become higher. Therefore we have dealt with energy demand influenced by ind!
oor air quality as well.

Abstract: Service Oriented Architecture (SOA) is an architecture style where software components that provide a piece of functionality communicate with each other via message they exchange. Within SOA these pieces are called services. Nowadays, the technology platform most associated with the realization of SOA is Web Services. Web Services have received much interest due to their ability to transcend programming language, operating system, network communication protocol, and data representation dependencies and issues. In this paper we suggest a new XML & Web Services Framework which relies on the Service Oriented Architecture and is a way of reorganizing applications into a set of services.

Abstract: In accordance with EPBD, energy certification of buildings has been compulsory in Hungary. Additionally energy consumption of heating, air-conditioning, ventilation and lighting shall be calculated separately as well as energy performance of buildings. We worked out new evaluation method of energy consumption air handling units based on probability theory. The new calculation procedure has been developed, in order to determinate energy consumption of air handling units. To achieve this, outdoor climatic parameters (temperature, humidity, enthalpy) has been considered as varieties. Using this method, comparison between alternative air handling units can be made during the design process. Since annually fluctuation of outdoor condition is taken into consideration, unnecessary over-dimensioning can be also avoided.

Abstract: This paper attempts to give a brief summary of the concept, objectives and research methodology of comfort theory and, in particular, thermal comfort for international building service engineers. It also provides an overview of the findings of international research and the goals of ongoing Hungarian projects (mainly carried out at the Department of Building Service Engineering and Process Engineering at the Budapest University of Technology and Economics). Moreover, the importance of comfort theory and its application by engineers will be highlighted. We intend to present the basic equations of the classical comfort theory, the equations of the human body’s static heat balance, and the so called comfort equation as well as its sensitivity depending on the thermic parameters of the microclimate. The PMV expression describing the thermal comfort of the human body and its sensitivity, derivatives and cross-derivatives is emphasized, too. The concept of dynamic ther!
mal sensation and the possibilities of its research is going to be introduced, which is possible only through the presentation of system theory, system dynamics and regulation theory.

Abstract: Air pollution belongs to environmental threats. This paper deals with an application of selected algorithms used in decision trees in order to an air quality modelling. We focused on daily observations of air polluting substances concentrations in one of the cities in the Pardubice region in the Czech Republic. After data collection, data description, and data preprocessing, we worked on the creation of classification models and the analysis of the achieved results. As modeling algorithms we selected C5.0 algorithm, boosting, CHAID method and CR&T. Differences of results were minimal.

Abstract: One of the major problems of ensuring optimal working of ground source heat pump systems is a heat transfer around vertical ground heat exchanger. The working of vertical U-tube can be understood as a heat exchanger between the ground and the heat carrying medium. In our case this heat carrying medium is fluid, which transfers the extracted heat from the ground to the heat pump. In winter we extract heat from the ground and in summer we transfer heat to the ground. In our paper we propose a simple calculation model to calculate the temperature change and the thermal resistance in vertical ground heat exchangers with single U-tube installation. We made calculations to obtain the amount of extractable heat from the U-tube in the function of different mass flow. We did these calculations for several periods of time, 1 day, 1 year, 10 years. We found that the amount of extractable heat in winter and in summer is between 10 – 80 % in the function of mass flow, and with!
elapsing time its values decline.

Abstract: In the recent times, CFD simulations [1], with the advent of computer architectures with superfast processing capabilities are rapidly emerging as an attractive alternative to conventional wind tunnel tests which are either too restrictive or expensive, for aerodynamic styling of a car. The paper describes comparative assessment of two distinct experimental strategies of aerodynamic predictions by conventional wind tunnel approach and its subsequent validation with advanced computational procedures, carried out as a part of design process of a small hybrid car proposed to be named as ADRENe. The experimental investigations were performed on an open circuit suction type wind tunnel having a 30cm x 30cm x 100cm test section, on a geometrically similar, reduced scale (1:15) clay model, while the three dimensional computational analysis was carried out using Gambit as the preprocessing software and Fluent as the solver and post processor. A good agreement between per!
formance values obtained independently by two experimental methods, suggests their reliability and suitability for further experimentation purposes. The comparison with computational approach shows that the computed drag forces and pressure distributions agree well with the experimental values over the entire range of air velocities, however, the agreement with the data for drag coefficient varies, which appears to suggest a higher degree of dependency on the grid quality and elements selection.

Abstract: This paper designs an IMS-based control architecture for IPTV(Internet Protocol Television) services on NGN and proposes a control method of them. The main idea of the control architecture is to add the IPTV multicast session control function to the CSCF(Call Session Control Function) of IMS, which makes IMS control not only the existing communication service but also the broadcasting service. And the function of profile management for HSS(Home Subscriber Server) subscriber is added to the management function for the IPTV subscriber. Also the information management function of the multicast group and the service(contents) is constructed additionally. The IPTV service interworking with the functions of IMS is controlled over the information management.

Abstract: The following document examines the four-stroke gasoline engine, which is used for the operation of a small irrigation pump. The engine was fuelled by gasoline and gasoline-10%ethanol mixture. During the experiments air pollution caused by the engine and its fuel consumption was measured. The engines’ power output was estimated by measuring the discharge produced by the pump keeping the pressure stable. A series of laboratory instruments was used for the realisation of the experiments and the results showed that the use of gasoline-ethanol mixture results in a CO and HC reduction. Engine speed was decreased and fuel consumption increased when alcohol petrol mixture was used, but not significantly.

Abstract: The following experiment is based on the gas emissions (CO, HC, NOx) of a farm tractor with diesel engine. It has been used a laboratory investigation in order to loud the tractor engine and measure the emissions by using Diesel fuel. Then the tractor was used for ploughing a field and the exhaust emissions were measured. According to measurements an estimation of the total emissions produced during field works were made for winter wheat and maize for silage crops under Greek conditions. The results showed that considerable emissions are produced contributing to environmental pollution. CO emissions are much higher than HC and NOx.

Abstract: Determinacy Analysis (DA) is a method that solves tasks of data mining (it enables to describe by the rules the subset of objects determined by the user). There are different treatments in DA: step by step and DAS-like in algoritmic view, one solution and multiple solutions as a result, additive and non-additive sets of rules in systematic view. Thereat the essence of the method itself does not change, only the rules change. There is a number of lacks in DA base algorithms: they are too labour-intensive (step by step approach) or they find only a limited set of rules (i.e. only one system of rules of many possible systems, in case of DAS). In this paper we show that DA can be reduced to the diclique finding task that is well-known from the graph theory, we present the prerequisites to take into account and explain how it influences the rules. The diclique-based DA enables to set up the DA tasks of new type: to find a system with minimal number of rules, to find a !
system with minimal number of shortest rules (for example). Reducing DA to a diclique finding task, the basis for the new generation of DA algorithms is founded.

Abstract: In this paper the modelling of the information , economic and social systems is presented. The models are based on the rough sets theory, and the fuzzy and rough sets theory. These models have represented two real information systems, and a system of an internal human population migration. The information systems are represented as a table where every column represents an attribute (a variable, a property). This attribute can be measured or may also be supplied by a human expert. To obtain the necessary data questionnaires were use. To the migration model selected socioeconomic data, indicators, are applied. Economic and demographic indicators that affect size of migration for districts in the Czech Republic are defined. In data pre-processing we focused on different processing of data inputs. It means for all indicators we used selected data discretization techniques. In the migration models creation phase we deal with a new design of membership function shapes an!
d rule base definition. The classifier models were carried out in MATLAB. Performed experiments have proven the accuracy of the proposed approach.

Abstract: Continuous piecewise linear models constitute useful tools to extract the basic features about the patterns of growth in complex time series data. In this work, we present an iterative algorithm for continuous piecewise regression with automatic change-points estimation. The algorithm requires an initial guess about the number and positions of the change-points or hinges, which can be obtained with different methods, and then proceeds by iteratively adjusting these hinges by displacements similar to those of Newton algorithm for function root finding. The algorithm can be applied to high volumes of data, with very fast convergence in most cases, and also allows for sufficiently close hinges to be identified, thus reducing the number of change-points, and so resulting in models of low complexity. Examples of applications to feature extraction from remote sensing vegetation indices time series data are presented.

Abstract: Classification of network traffic is the essential step for many network researches. However, with the rapid evolution of Internet applications the effectiveness of the port-based or payload-based identification approaches has been greatly diminished in recent years. And many researchers begin to turn their attentions to an alternative machine learning based method. This paper presents a novel machine learning-based classification model, which combines ensemble learning paradigm with co-training techniques. Compared to previous approaches, most of which only employed single classifier, multiple classifiers and semi-supervised learning are applied in our method and it mainly helps to overcome three shortcomings: limited flow accuracy rate, weak adaptability and huge demand of labelled training set. In this paper, statistical characteristics of IP flows are extracted from the packet level traces to establish the feature set, then the classification model is created a!
nd tested and the empirical results prove its feasibility and effectiveness.

Abstract: In this article we address the problem of determining how a structured formation of autonomous undistinguishable agents can be reorganized into another, eventually non-rigid, formation based on changes in the environment, perhaps unforeseeable. The methodology can also be used to correctly position the agents into a particular formation from an initial set of random locations. Given the information on the agents current location and the final locations, there are n! possible permutations for the n agents. Among these, we seek one that minimizes a total relative measure, e.g. distance traveled by the agents during the switching. We propose a dynamic programming methodology to solve this problem to optimality. Possible applications can be found in surveillance, damage assessment, chemical or biological monitoring, among others, where the switching to another formation, not necessarily predefined, may be required due to changes in the environment.

Abstract: In this paper it is explained a new approach for clustering Gene Ontology (GO) terms by examining microarray data related to them. By segmenting the entire ontology in a single specific level, and applying techniques as discrimination and ranking of features to those GO terms that are contained in that level, it is produced a characterization of the contained terms, as feature importance vectors related to the gene expression patterns that are included in the microarray dataset. By utilizing data mining techniques to cluster the vectors, it is concluded that this new approach may help to obtain relations that are normally hidden among GO terms, not only the ones in the same contained ontology, but also getting a trans-ontological relationship of them.

Abstract: The aim of the present study was to develop a new method for fast localization of the face from streaming colour video. In the method, the face is located by analysing local properties of four facial landmarks, namely, regions of eyes, nose, and mouth. The method consists of three stages. First, the face-like skin-coloured image region is segmented from the background and transformed into the grey scale representation. Second, the cropped image is convolved with Sobel operator in order to extract local oriented edges at 16 orientations. The extracted edges are further grouped to form regions of interest representing candidates for facial landmarks. The orientation portraits, which define the distribution of local oriented edges inside the located region, are matched against the edge orientation model to verify the existence of the landmark in the image. The located landmarks are spatially arranged into the face–like constellations. Finally, the best face-like const!
ellation of the landmark candidates is defined by a new scoring function. The test results showed that the proposed method located neutral, frowning, and smiling faces with high rates in real time from facial images under controlled head rotation variations.

Abstract: Specialisation studies are an efficient and flexible way of completing and updating professional knowledge, since the multi way of learning also suits the timetables of those who work and study simultaneously. In this design-science research, a new innovation in adult education, 'Network Design Specialisation Studies' is executed and evaluated. The theoretical background consists of Learning by Developing (LbD), expansive virtual learning and virtual empowerment, and adult learning. Laurea University of Applied Sciences' strategy is to integrate its three statutory tasks of education, research and development, and regional development by utilizing its LbD model. Laurea's Network Design Specialisation Studies splice virtual learning and LbD. Virtual learning includes virtual lessons, exercises and examinations, but its main innovative part is a virtual laboratory with a virtual laboratory engineer. Laurea's new virtual learning environment plays a remarkable role of!
developing the competences of each individual learner, while the LbD concept steers the entire specialisation studies. This study shows that LbD and virtual learning support each other. Utilizing Web 2.0 technologies in the future, Laurea's innovative learning environment could be a part of global expert communities. This may lead to the materialization of the virtual empowerment, influencing the development of the future society during the next decade.

Abstract: This paper describes the modeling of a two-vehicle convoy and the design of a vehicle following controller that tracks the trajectory of the vehicle ahead with prescribed inter-vehicle distance. Kinematic equations of the system are formulated applying standard robotic methodology. We consider autonomous vehicle following without any information obtained from road infrastructure or communicated from the lead vehicle. Assuming that the leader linear and angular velocities, as well the curvature radius of the path traveled by the lead vehicle, are unknown constant parameters, an adaptive tracking controller is proposed. With only the current inter-vehicle relative position and orientation available for feedback control, the control velocities of the following vehicle are computed using the leader velocity estimates obtained from the dynamic (adaptive) part of the proposed controller. For constant velocity maneuvers of the leader, at steady state, the two-vehicle con!
voy will travel concentric arcs of same radii with prescribed inter-vehicle spacing. For time-varying lead vehicle velocities, the proposed controller achieves ultimate boundness of the closed-loop system in error coordinate. Various simulation results demonstrating the performance of the controller are included.

Abstract: Digital watermarking was commenced to copyright protection and ownership verification of multimedia data. However the evolution of the watermark focused on different security aspects of multimedia data such as integrity and authenticity. Fragile and semi-fragile watermarking schemes were introduced to accomplish these requirements. In this paper, we propose semi-fragile watermarking scheme to authenticate visual content of the image. The proposed method occupies in DCT domain of the particular image. Low frequency components are considered as a visual content and authenticate particular number of low frequency components instead all coefficients. In this proposed scheme the watermark is the digital signature of the visual content. Authenticating the selected number of coefficient the proposed scheme reduces the computational complexity and cost. Digital signature is generated following the elliptic curve digital signature algorithm (ECDSA). Thus, the scheme is fast!
er than RSA based authentication definition and it provides high level of security and availability. Additionally our scheme localizes the compromised area of the image. Experimental results shows watermark does not make any visual artifact on original data, however the degradation of compression ratio due to alternation in quantization table, is evaluated. Results give evidence that compression ratio degradation is ignorable for average quality factors.

Abstract: The Transaction Processing Monitor (TPM) is the most-used middleware in different e-commerce systems from large enterprises to medium and small businesses available in the internet. Due to its growing popularity, the necessity for a more efficient TPM performance is now the major concern between the developers and researchers. The need for a high-end benchmark platform for a TPM is at present very vital to meet the high performance needs of online transactions. In addition to the performance characteristics of the TPM, we also have to ensure the security of the transactions. In this paper, we perform a detailed analysis of the current software packages available for this application. And therefore, we propose a secure, isolated, and highly configurable environment using the real-time emulation capabilities of NS2 and the virtualization capabilities of Xen, in order to provide a testbed with the characteristics and behavior of a real network.

Abstract: The paper presents the results of an experimental investigation of the von Karman vortices formation at the blade trailing edge of a large scale turbine cascade. The mean and time varying characteristics of the flow in the trailing edge region were measured by means of a two-component fiber-optic laser Doppler velocimeter over an experimental grid very close to the blade trailing edge. A phase locked ensemble averaging technique has been applied to separate coherent and incoherent contributions in the instantaneous LDV data. The trailing edge of the central blade of the cascade has been instrumented with a multisensor surface mounted hot-film probe. The probe outputs proportional to the instantaneous wall shear stress were sampled simultaneously with a filtered reference signal from a hot-wire probe located in the wake and sensitive to the vortex periodicity. Organised periodic structures have been clearly identified in the flow and their evolution in time has b!
een documented through a sequence of instantaneous pictures of the periodic flow field during a cycle of the vortex shedding. Time-averaged and time-resolved ensemble averaged wall shear stresses on the blade trailing edge help to identify the positions where the boundary layers separate and to analyze the effects of the vortex shedding on the wall shear stress along the trailing edge.

Abstract: The present paper analyzes adjacent channel interference in TETRA Direct Mode Operation (DMO) for indoor and outdoor environments. To determine minimal stay-away distance and interference area propagation model is used. Thus, a brief overview of free space, Bacon and CEPT SE21 propagation models, mentioned in the TETRA DMO standard is given and two-ray and multi-wall models are described and evaluated by field measurements. We found out, that the two-ray model is suitable for fast estimation of the TETRA DMO signal coverage in open flat area while the multi-wall model, taking into account the attenuation of walls between transmitter and receiver, gives good estimate of the signal levels for indoor applications. Those two models were used for the interference analyses. According to the calculated results two-ray model gives rather pessimistic values of the stay-away distance and interference area in open flat areas while multi-wall model is appropriate for the inter!
ference calculation inside buildings that are not surrounded with the high structures causing additional ray reflections back into the interior of the analyzed building

Abstract: In mammals, cytosines of most CpG dinucleotides in their genomes except gene promoters are subject to modification by methyl group (methylation). A number of genes in a mammal are regulated developmental- specifically or tissue-specifically by the methylation. Mammalian DNA methylation contributes to regulation of gene expression, repression of parasitic sequences, inactivation of X chromosome in female, genomic imprinting, etc. Aberrant methylation results in a part of cancers and genetic diseases in human. Therefore it is required that methylation status on human genome is comprehensively revealed in each kind of cells. However, since comprehensive methylation analyses require a lot of times and large labor, methylation status on only a part of genomic regions is revealed in mammals. Because of this, machine learning using already known methylation data and prediction of methylation status on other genomic regions are important. Moreover, since sequence differenc!
es between DNA regions showing different methylation status also remain unclear, those differences should be also determined. Therefore we conducted machine learning by support vector machine using our previously reported methylation data, and predicted methylation status on DNA sequences using DNA sequence features. Furthermore we explored different sequence features among four types of methylation using random forest. Consequently high methylation prediction accuracies were observed between two different methylation status pairs. Moreover it was revealed that sequences containing CG, CT or CA were important for discrimination between them.

Abstract: The main aim of the paper is to introduce a novel method - based on fuzzy control and linear parameter varying (LPV system representation transformable into HOSVD based Canonical form - for modeling deformation processes with respect to the distribution of the absorbed kinetic energy. Modeling such kind of processes requires many uncertain input parameters. Using the proposed concept we are able to handle them and keep the complexity of the models low by using higher order singular value decomposition (HOSVD) technique.

Abstract: In this paper, we develop a cross-layer based joint algorithm for power control and scheduling. We applied the algorithm in CDMA wireless adhoc networks to determine the optimum set of admissible users with optimum transmitting power level, so as to minimize the interference level and call rejection rate. Using the two alternating phases namely scheduling and power control, the multiple access problem is solved. As part of a contention-based multiple access protocol, the concept of power control has been initiated. It characterizes successful transmissions, which are depending on a set of signal-to-interference-and-noise ratio (SINR) constraints (which directly translates to quality of service (QoS) constraints on the bit-error rate (BER) at individual receivers). So as to eradicate strong levels of intervention that cannot be trounce by power control, the scheduling algorithm is necessary in permitting the transmissions of static and mobile users of multi service !
classes. The performance of our algorithm in a set of admissible and non-admissible users has been assessed using simulation results. Moreover, it is exposed that power control algorithm converges for a set of admissible users.

High dynamicity affects the design and implementation of distributed applications by significantly increasing their complexity, to consider not only routing and node configuration issues, but also the possible mobility of software components and the loss of direct connectivity during service provisioning. The proxy role is assigned dynamically in a completely decentralized way. Proxies exploit code mobility to install only when and where needed. In this work, we estimate and compare the performance of routing protocols for ad-hoc networks, namely Ad Hoc On-Demand Distance Vector protocol (AODV) and Dynamic Source Routing (DSR). We use the file transfer protocol to measure the performance of our model. The protocol provides file downloading from a dynamically discovered service co!
mponent available in a MANET locality, even if the server moves during file transfer

Abstract: Abstract: - In this paper, we develop a cross-layer based joint algorithm for power control and scheduling. We applied the algorithm in CDMA wireless adhoc networks to determine the optimum set of admissible users with optimum transmitting power level, so as to minimize the interference level and call rejection rate. Using the two alternating phases namely scheduling and power control, the multiple access problem is solved. As part of a contention-based multiple access protocol, the concept of power control has been initiated. It characterizes successful transmissions, which are depending on a set of signal-to-interference-and-noise ratio (SINR) constraints (which directly translates to quality of service (QoS) constraints on the bit-error rate (BER) at individual receivers). So as to eradicate strong levels of intervention that cannot be trounce by power control, the scheduling algorithm is necessary in permitting the transmissions of static and mobile users of mu!
lti service classes. The performance of our algorithm in a set of admissible and non-admissible users has been assessed using simulation results. Moreover, it is exposed that power control algorithm converges for a set of admissible users.

Abstract: This paper present a real time identification of the parameters value of a slow process using adaptive IIR-OSLMS filters. This kind of process can be assimilating to a time constant and a delayed time. To ensure the convergence of the adaptive algorithm the initial values of the parameters can be compute using an on-line identification method. The measured temperature is affected by noise, so it was used a ALMS filter to reject the noise.

Abstract: The Electric Arc Furnace (EAF) is a very large power load, determining the negative effects on the power quality like flicker effect, harmonics currents, and reactive power. These effects are due to the nonlinear characteristic of the electric arc. In this paper is made a study based on simulation about flicker effect caused by Ultra High Power Electric Arc Furnaces (UHP-EAF). For simulation it was use two electric arc models, depending on the nonlinearity of the electric arc. The models are implementing in PSCAD EMTDC simulation program, a program dedicated to power systems. The simulation results are comparing with measurements made in an industrial plant in Romania.

Number of paper pages: 10
Abstract: This study was conducted in a food processing company on its Rusk production line. The goal of the study was to increase the production rate of the line to meet the continuously increasing demand on its product within the existing limited space in the plant. The production line was thoroughly studied and analyzed. Several bottlenecks that were causing sever congestions in different areas on the production line were found. An Arena Simulation model was developed and used to resolve all bottlenecks found on the line and a simulation experiment consisting of seven different scenarios was conducted to search for a good feasible solution to increase the production rate.The changes made in the production line resolved all bottlenecks, improved utilization of all production equipment, eliminated all congestions and most of the queues at all production stations. An increase of about 50% in production and a decrease of 11.4% in average total production time for a box of Ru!
sk in the system were achieved. The capital investment required to implement the new improvements can be paid back in a period of 35 days from the expected profit that would be realized from the additional increased quantity produced. The changes that were made on the production line to achieve the above improvements were adding two new machines, replacing three other old machines, modifying two other machines and decreasing the time of one of the processes, without affecting the quality of the product.

Abstract: The current study analyses entropy generation induced by coupled forced convection and thermal radiation heat transfer, in circular tubes and for non-grey media. A laminar flow of over heated water vapour in the entrance region of the duct was investigated. A specially developed numerical model, based on the finite-volume technique, is used for the solutions of the governing differential equations. The radiative transfer coefficients are deduced by use of the gRay Tracingh method through S4 directions, in combination with the statistical narrow band correlated-k (SNBCK) model. The local entropy generation distributions as well as the overall entropy generation in the whole flow fields are analyzed. The developing of velocity and temperature fields is also presented in this study.

Abstract: This paper reports on the findings of a study on the problems of Solid Waste Management (SWM) on Mountain Kilimanjaro (MK) which is located within Kilimanjaro National Park (KINAPA) in Northern Tanzania. The study was prompted by the fact that flourishing tourism activities on the mountain over the years has resulted into the increase in the tonnage of Solid Waste (SW) generated and thus posing serious challenges in its collection and disposal. The methodology employed in this study included physical observations and questionnaire surveys, as well as waste sorting and weighing to quantify and characterize waste loads collected from each tourist route station covered in this study. On the basis of the established SW generation rate (0.6 kgca-1day-1) a total amount of SW generated was estimated to range from about 87 tons (in 2003) to 125 tons (in 2006). An improvement in SW collection from 64% in 2003 to 94% in 2006 was also noted. This improvement can be attribute!
d to the Trash–In–Trash-Out (TITO) system of SW collection which is currently practiced by the management of KINAPA for SWM on MK. The study also reveals a potential environmental pollution including air pollution emanating from open burning and pit disposal of SW. Based on average percentage values of waste components and the estimated quantity of waste generated, it was established that the total waste quantum contains about 34% of recyclables. The study recommends that resource recovery and conservation measures through waste recycling and re-use be instituted as one of the options for sustainable SWM on MK.

Abstract: In this paper, two new lower boundaries named Extended Machine-Based Lower Bound and Extended Job-Based Lower Bound on Jobshop scheduling problem with objective makespan function are being issued. In order to calculate the extended low boundaries, situations are being considered in which, that processing of operations by machine, is not possible. With making use of the given low boundaries, better estimation relative to optimized response can be obtained. No matter how much the low boundary is close to the real optimized boundary, the evaluation of obtained results from different algorithms will be carried out with more precision. Low Extended boundaries were computed on 80 available test problems. After computing extended low boundaries, they are compared with available boundaries; results show that on 55 percent of the available results cases had development relative to previous results.

Abstract: Artificial vision, in spite of all theoretical and practical progress accomplished during last thirty years, still cannot be employed technically in some hazardous and strong industrial areas, where conditions are such that cameras would not operate properly. Possible alternatives on such problem are the quite recent IP65 and IP67 industrial cameras, and associated connectors, protected by an anticorrosive, waterproof, and high temperatures resistive carcass employing a dedicated electronic, in addition robust to almost 3G accelerations. Nevertheless, such cameras are still very expensive compared to conventional industrial cameras and would still not be enough in hardest conditions (explosive gas or dust environment) or in electromagnetic interferences environments. A good alternative in extreme conditions is the use of optical fiber bundle. Since such cable only transmits light, they intrinsically have electromagnetic interferences immunity and, depending on the !
fiber material, could be exposed to very high temperature (over 1000ºC for sapphire fibers for example), could be employed in almost all corrosive environment, and are totally submersible. Nevertheless, the coherent optical fiber bundles are very expensive, and for large distances could be non-competitive facing the other hardware solutions (armor plating, electromagnetic interferences isolation). Thus, the best suitable option to develop a competitive system in those particular cases is the use of incoherent optical fiber bundle (IOFB), nowadays just employed for illumination tasks. Image transmission in this case is not direct but require a calibration step that we discuss in this paper. Improvement of the noisy resulting quality image is also exposed here, achieved by experimental post calibration methods. We propose in this work a new calibration method of incoherent optical fiber bundle (IOFB) for image transmission purpose. Firstly, we present the calibration method !
(an enhancement of previously published calibration methods), some res
ulting reconstructed images and a discussion on its quality improvement employing simple denoising methods assisted by low pass filters (smooth filter, resizing method,…) . We finally depict the two new post calibration methods, and its associated noise generator physical phenomena we want to treat. Those two post calibration method are: correction of the input plane optical aberrations and extraction of a unique pixel (almost centered) for each fibers. We finally present some resulting images that demonstrate how it efficiently refine the reconstruction Look Up Table (LUT) used for the output image reconstruction improving image quality, image contrast but also reconstruction processing time.

Abstract: With the widespread deployment of biometric systems in various applications, there are increasing concerns about the security and privacy of biometric technology. Although many of biometric techniques can be applied to enhance security, even more protection tools are required to keep safe our biometric system at various attack points, for example an attacker may steals templates from a database and constructs artificial biometrics that breach authentication. It indicates that our biometrics templates are not secure, a solution should be device for template-protection, which make it impossible to recover the actual biometric data from the templates. Here in this paper, we focus on biometric template security which is an important issue because unlike passwords and tokens, biometric templates cannot be revoked and reissued. We present an idea with the help of cancelable biometrics to protect templates in database in an efficient manner.

Abstract: This paper deals with the problem of evaluating a usability of information systems in public administration based on a theory of fuzzy sets. For such purpose, a completely new methodology has been created. The evaluation of the model is based on a set of criteria that synthesizes commonly used Web usability guidelines. Together with the model, Fuzzy Usability Evaluator – an application that is able to operate with the vague nature of evaluating has been developed. While the inputs are fuzzy measures, the output of the model is a crisp value representing an overall usability score of the Web portals in Public administration.

Abstract: Mobile robots are characterised by their capacity to move autonomously in an environment that is either known or unknown or only partially known. Their uses and applications are wide and are incorporated into a great many fields including underground and submarine work, space missions, security systems, military applications, and many more. It is for this reason that that a mobile robot is rarely fitted with only one sensor to carry out all of its multiple tasks, being much more frequent the use of various sensors combined within the system that complement one another to complete their different functions. In this way it is possible to find robots where estimation of position1 and the updating of the map is carried out by video cameras or laser scanners, while obstacle detection is achieved using sonar. In this respect it is important to highlight the close relationship that exists between the problem of position estimation and that of the construction of a map of !
the surroundings, with exact localisation of the robot necessary to be able to carry out map construction and vice versa. In this work we focus solely on the problem of localisation, comparing different estimation algorithms of the trajectory taken by a robot from the observations and readings obtained by the robot itself. In our problem, we will work with images taken by a stereoscopic vision system of uncalibrated cameras, we will assume that the movement of the robot is on a flat surface and we will use natural landmarks. As we will see, the information obtained from this type of sensor allows a robust estimation of movement taken between each pair of observations without the need to use the information from the robot's propioceptive sensors. The solution of this problem, known as visual odometry, is critical within the majority of subsequent navigation processes.

Abstract: At the following essay it will be examined the use of gas propane in a small four-stroke engine of internal combustion that is used for the movement of a small alternative generator. The generator functioned at different electrical loads 500W, 1000W, 1500W and 2000W. During the use of propane was observed CO and HC emissions decrease under different load. The flow of propane was regulated so as until the load of 2000W the behavior of the engine from the aspect of efficiency to be the same with that of gasoline. This means that when gasoline was used and also when propane was used the engine rpm were the same for every electrical load. During the tests, the consumption of gasoline and propane was recorded and it was observed that it increased when the electrical load was increased. The gas propane consumption that was recorded was that which gives the same behavior of the engine from the aspect of power that the manufacturer gives for the use of gasoline.

Abstract: In this paper will be examined the use of gasoline-methanol mixtures in a four-stroke engine, which is used for the move of an alternative generator. In the tests the gas emissions and the fuel consumption, where examined at idle and under full load(1KW) conditions. Specifically, the mixtures: gasoline, gasoline-10%methanol 20%methanol, gasoline-30%methanol, gasoline-40%methanol, gasoline-50%methanol, gasoline-60%methanol, and gasoline-70%methanol where tested, without any regulation of the engine relatively to the air/fuel ratio, maintaining the original adjustment that concerned gasoline was maintained. An important reduction of emissions was noted while the percentage of the methanol was increased. During the tests the fuel consumption was recorded for every mixture separately and for every load condition. It was observed a small increase of consumption when the percentage of methanol in the fuel was increased.

Abstract: Development of bio-mimetic entertainment dolphin robots that act like real dolphins in terms of autonomous swimming and human-dolphin interactions are introduced. Body structures, sensors and actuators, governing microcontroller boards, swimming and interaction features are described for a typical entertainment dolphin robot. Actions of mouth-opening, tail splash or water blow through a spout hole are the typical responses of interaction when touch sensors on its body detect users¡¯ demand. A pair of microphones as the ears of a dolphin robot, in order to improve the entertainment dolphin robot¡¯s ability to interact with people, is used to estimate the peak sound directions from surrounding viewers. Dolphin robots should turn towards people who demand to interact with them, while swimming autonomously.

Title of the Paper: Improving the accuracy of effort estimation through fuzzy set combination of size and cost drivers

Abstract: In this research, it is investigated the precision of size and cost drivers in the estimation of effort using Constructive Cost Model (COCOMO). It is imperative to stress that uncertainty at the input level of the COCOMO yields uncertainty at the output, which leads to gross estimation error in the effort estimation. Instead of using a single number to represent the size, it can be characterized as a fuzzy value. Cost drivers also expressed through an unclear category which needs subjective assessment. Fuzzy logic has been applied to the COCOMO using the symmetrical triangles and trapezoidal membership functions to represent the cost drivers and size. Using trapezoidal membership function for the size and cost drivers, a few attributes are assigned the maximum degree of compatibility when they should be assigned lower degrees. To overcome the above limitations, in this work, it is concentrated to use Gaussian membership function for the COCOMO parameters. In ad!
dition, this paper proposes to incorporate both size and cost drivers together, with a fuzzy set using Gaussian membership function. The present work is based on COCOMO dataset and the experimental part of the study illustrates the approach and compares it with the standard version of the COCOMO. It has been found that the proposed method is performing better than ordinal COCOMO and the achieved results were closer to the actual effort.

Abstract: The authors present a new remote user authentication scheme on three dimensions for multi-server environments. The merits include: the scheme can be used in multi-server environments; the system does not need to maintain any verification table; the users who have registered with various servers do not need to remember different login passwords for each; the ability to choose passwords freely and change them offline; mutual authentication is provided between the user and the remote system; a session key agreed by the user and the remote system is generated in every session. Furthermore, we propose a specific Access Right (AR). The AR means the legal users have different level of authorization based on which server in the multi-server environment in used.

Abstract: Abstract: Analysis of heart rate variation (HRV) has become a popular noninvasive tool for assessing the activities of the autonomic nervous system into two categories one having the risk of sudden cardiac death and the other not having the risk .Heart rate variability refers to the beat to-beat variation in heart rate (HR) and is modulated largely by the autonomic nervous system via changes in the balance between parasympathetic and sympathetic influences. Since short-term variations in HR reflect sympathetic nervous activity, they provide useful non-invasive markers for assessing autonomic control under various physiologic states and conditions. The graphical tools used to represent the nonlinearity are Poincare plots, Recurrence plots, Lorenz plots and Difference plots. To highlight the variations in HRV signals, and to quantify the nonlinearity, nonlinear measures such as Approximate Entropy and Cross approximate entropy are used.. The present paper gave the re!
sults of analysis using the graphical tools such as Poincareplots, Recurrenceplots and Lorenz plots which were drawn with the available data applied to the tools which are available for analysis..The algorithm and implementation of only difference plots was done using Labview and it is compared with the remaining graphs and alsowith the measures of quantification. The results are showed next. The recurenceplots online.com was used to plot the recurrence plots.Wsess.com is used to plot Lorenz plots," HRV ANALYSIS SOFTWARE" was used to plot Poincare plots with the data.The difference plots were plotted by writing the code using Labview. The algorithm for entropies are wrote and implemented using Clanguage. Using the above mentioned methods the ECG data was classified into two categories ashaving presence of cardiac risk or not for the subjects having some illness related to ANS.

Abstract: Tentacle manipulators produce changes of configuration using a continuous backbone made of sections which bend. In this paper, a new project for controling a continuum robot is presented. The robotic structure uses cables to transmit forces to the elements of the arm. This new robot is actuated by stepper motors. Due to the difficulties of using distributed sensors along the manipulator structures, it was decided to use a vision system. The vision system is composed by two pan / tilt / zoom cameras and a frame grabber. A graphical simulator was designed and implemented in order to test the robot behavior under certain circumstances. The camera calibration using this graphic simulator is also presented. The term of "camera calibration" in the context of this paper refers to positioning and orienting the two cameras at imposed values.

Abstract: Carbon dioxide diffusion into n-decane inside cylindrical and square glass capillary tubes has been modeled [1,2], with two different models for each tube and the convective model for the square tube depended on the results of the cylindrical one. For those models, the liquid phase density was always considered constant and its value was adjusted from the experimental data of gas-liquid interface position. This approach was done using the diffusivities obtained by correlations which modify the infinite dilution diffusion coefficient using a thermodynamical factor. Now, the liquid phase density is considered variable on time with perfect mixing inside the phase and an effective diffusivity can be determined. This effective diffusivity involves the molecular and convective contributions to the global mass transfer. Both interface displacements (inside cilyndrical and square tubes) can be modeled using the same model without dependency between their results. The term!
s inside the finite difference matrix for the liquid phase are not constant, because they depend on the solute concentration and on the liquid density then an iterative calculation for the matrix coefficients must be done in each timestep. A partially implicit model considers this iterative calculation keeping the liquid density value for the previous time (j). A fully implicit model considers this iterative calculation keeping the liquid density value for the present time (j+1). It was showed that the model results, adjusted to the experimental interface position values, predicted effective diffusivities which are variable on time. The simulation time (76 min) for the fully implict numerical model is higher than the simulation time (62 min) for the partially implicit numerical model. It was found that the type of numerical solution scheme affects the results (up to 5% deviation) for the square capillary model but it doesn´t change the cilindrical capillary model resu!

Number of paper pages: 10
Abstract: This paper reveals a sequential decomposition method based on Convolution Kernel Compensation (CKC). It operates in real time and can decompose linear mixtures of finite-length signals. Multiple-input multiple-output (MIMO) signal model is used with finite channel responses and trains of delta pulses as inputs. Our approach compensates the channel responses and reconstructs the input pulse trains in real time, when samples of the observed signals become available. Two versions of the sequential decomposition were tested: sample-by-sample and multiple sample input. The time complexity of the two approaches, is analytically evaluated and supported by the experimental measurements. Performance tests on the synthetic surface electromyograms (sEMG) provide estimations of average rate and standard deviation of the reconstructed pulse trains for single motor units (MU).

Abstract: - Turkey has one of the largest and fastest growing populations within the EU-27 Member States and Candidate Countries. This population growth comes with a rapid urbanization and high demand for electricity. However, Turkey's conventional energy resources are limited and this high energy demand has resulted in a high dependency on energy imports; primarily oil and natural gas. At present, around 30 per cent of the total energy demand is being met by domestic resources, while the rest originates from a diversified import-portfolio. Turkey, on the other hand, is blessed with ample renewable energy resources such as wind energy and solar energy. This paper makes a quick review of Turkish Energy outlook and emphasizes the importance of renewable energies for Turkey. Afterwards it analyzes the new era of Renewable Energy in Turkey, through the analysis of the recent advances in the legal infrastructure, latest agreements and projects for the advancement of renewable ene!
rgy sector in the country. It is accepted that the most important renewable resource of the country is the wind energy and this paper concentrates on the wind energy potential in general. One of the most significant criteria for the feasibility of the wind related investments is the grid connectivity. Since Turkey acts like a network hub between the Europe and Asia, the quality and the management of the grid and the grid connectivity of the renewable projects is important not only for this country, but for EU member states as well. Because, the Marmara region has the highest wind energy potential and it is the western most region of the country, this paper concentrates on this region as a case study. The final part of the paper analyzes the grid connectivity to Europe, EU directives and their impact on Turkey's grid management.

Abstract: - With a young and growing population, low per capita electricity consumption, rapid urbanization and strong economic growth, Turkey for nearly two decades has been one of the fastest growing power markets in the world. The main objective of the Turkish energy policy is primarily focused on meeting the national energy demand in a reliable, sufficient, timely, economic and environmentally sound manner so as to realize and sustain the economic and social development targets. Being accepted as a quality and a clean energy resource, planning for electricity production is considered to be vital for the development of this country. Renewable energy resources including solar energy is expected to play an important role in the electricity production as well. According to the experts, renewable sources priority list includes wind energy utilization; small hydraulic plants of less than 50 MW with or without (preferably) reservoirs, and solar thermal at the very top. When all!
the potential renewable energy sources of Turkey is considered, hydraulic and wind (Table 2) and solar (Fig. 3) energies can meet almost 1/3 of the total demand and a very high percentage of the electricity production in the country. As it is well known the most significant form of incentive used by European Union member countries for renewable source based projects is the purchasing guarantee of the electricity produced which necessitates easy access to electrical grid and a sound management of the grid. Many experts identify connection of the renewable based electricity production systems to the national grid as one of the leading obstacles. Table 4 gives the regional availability of the renewable resources and critical analysis of grid availability. A road map to the proper grid management which would pave the way for easy connection of the renewable based electricity production systems is proposed..

Abstract: Renewable Energy production is becoming more important day by day due to a rapid increase for reliable, sufficient, timely, and economic and environmentally energy production. Public awareness about environment has a great impact on choosing the renewable resources for the renewable based electricity production systems. The Commission on Environment of the Turkish Grand National Assembly approved the Kyoto Protocol on Global Warming in June 2008, which makes the importance of renewable energy one step more important for Turkey. When all the potential renewable energy sources of Turkey is considered, hydraulic and wind and solar energies can meet almost 1/3 of the total demand and a very high percentage of the electricity production in the country. However country-wide planning of production and distribution is vital just because the potential of renewable resources diversed among the geographical regions and according to the time of the year in Turkey. The current !
structure of Turkey's energy policies, latest developments, and renewable energy potentials has analyzed. For planning and distribution scenarios five different regions of Turkey is used for sample data in means of wind, hydro and solar renewable energy potentials. A road map and a fuzzy expert system for a possible planning and distribution road map has been proposed

Abstract: This paper presents the simulation results of electric field and potential distributions along surface of silicone rubber polymer insulators under clean and contamination conditions. In former experimental research, silicone rubber polymer insulators having near the same leakage distance are subjected to 15 kV during 50 test cycles of artificial salt fog ageing test. After 50 test cycles, alternate sheds silicone rubber polymer insulator showed better contamination performance than straight sheds silicone rubber polymer insulator. Severe surface ageing was observed on the straight sheds insulator. The objective of this work is to elucidate that electric field distribution along straight sheds insulator higher than alternate shed insulator in salt fog ageing test. Finite element method (FEM) is adopted for this work. The simulation results confirmed the experimental data, as well.

Abstract: Abstract: - This paper proposes a grid-connected photovoltaic (PV) system that is consisted of a boost converter with maximum power tracking, battery charge controller, inverter, and the related control circuits. A sliding mode controller is designed for controlling the boost converter to output the maximum power of the solar cells. A control strategy is proposed of a Maximum Power Point Tracking (MPPT) impendence adapter coupling a photovoltaic generator to a battery. The proposed strategy is based on the sliding mode control theory of continuing systems to permit a direct control of power converter. The PV generator price is even relatively high, so the user is interested of the optimal coupling of PV generator to electromechanical loads. In fact, this system uses the optimal coupling in order to have maximum power during the whole operating period. A grid-connected inverter is designed to transform the maximum output power into the load and utility. The real po!
wer control is using zero-cross and phase-lock circuits that control the inverter output voltage which is phase lead and synchronized with the utility. A digital circuit is used to detect the phase angles of the load voltage and current to control the inverter output amplitude to achieve the reactive power load compensation. A monitor circuit is designed to detect the voltage and frequency variation in the utility. When the photovoltaic system encounters a voltage and frequency deviation, the monitor circuit immediately disconnects the photovoltaic system from the utility to prevent the island effect. The proposed system is implemented by using OP amplifiers and micro controller (PIC16F877A). Both the simulation and experimental results using MATLAB show the sliding mode controller for maximum power tracking has good performance. The phase and amplitude control experiments achieve the real and reactive power control. The island effect experiments demonstrate evidence of the!
solar cell system protection ability illustrating the proposed grid-c
onnected photovoltaic system has good operating performance.

Abstract: The subject of this paper is a study of the influence of the inertial sensors errors on the position, speed and attitude of a bidimensional strap-down inertial navigation system in a horizontal plane. The MATLAB/SIMULINK models used for the acceleration and rotation sensors are based on the sensors data sheets and on the IEEE equivalent models for the inertial sensors. The models can be used in the numerical simulation of the strap-down inertial navigation system, close by real conditions from the point of view of the distortions suffered by the useful acceleration and rotation signals at the passing through any type of accelerometers or gyros desired to be implemented in the navigator. These models have the advantage to work independent from each of the sensors' errors and thus to study their influence on the inertial navigator.

Abstract: Stirling engines are known as high efficiency engines. In theory their efficiency is equal to Carnot efficiency, but in practice due to some reasons their efficiency reduces. One of the most important sources of efficiency reductions is imperfect heat transfer. In this way, heat exchangers are key components in the Stirling engines. There may be three or four heat exchangers in the Stirling engine system, these heat exchangers are Heater, Regenerator and Cooler which exchange heat to and from the engine. The design and configuration of these heat exchangers effect on engine performance. The optimization of these parts for a 20 kw Stirling engine is shown in this paper.

Abstract: An efficient and secure protocol in certified e-mail delivery is proposed in this paper. With the widespread use of public Internet, communication via electronic mail (e-mail) becomes a convenience application instead of traditional manuscript letter. People can easily append his/her digital signature to the e-mail in order to achieve the goal of non-repudiation of origin. However, the evidence of receipt still relies on the willingness of the recipient in the standard e-mail service. Hence, the recipient has no responsible for the received e-mail. In this paper, we present an efficient and secure protocol in fair certified e-mail delivery (CEMD). Our protocol efficiently provides non-repudiation of origin and receipt in the fair manner. In other words, the sender can obtain the irrefutable receipt if and only if the recipient gets the certified e-mail from the sender, otherwise, neither of them. Moreover, the proposed CEMD is efficiently in sending the other mails!
to the same recipient by using the pre-computation function. As the evaluations of computational cost and communication overhead, our protocol is cost-effective and efficient than other relevant protocols.

Abstract: Many of the organizations, companies, and industries today are focusing on User Experience to differentiate themselves from competitors in the design and development of products, services, and/or applications. Intel Corporation which has primarily been a semi-conductor manufacturing company for a long time has shifted its focus to address the needs, desires, and expectations of users. The fundamental question to be answered is how to design and develop different products, services, and/or applications that add value to users and enhances their experiences. This paper addresses this fundamental question through a systematic approach of understanding the competitive landscape environment. The paper describes the results of the systematic approach in the context of consumer electronics (CE) domain and concludes with the benefits of understanding the competitive landscape environment.

Abstract: Wu Elimination Method is applied to obtain analytical solution of power flow equations without either extraneous roots or missing roots. The symbolic process of Wu Elimination is implemented by software MAPLE. A minor group of solutions is obtained under low load other than the major group of solutions. Based on computation, analytical V-P , V-Q curves as well as the steady state operation area. The results are compared with the results of Homotopy Method. Discussion on unstable equilibrium points is presented which is potentially valuable for research on voltage stability and angle stability of complex power systems.

Abstract: The digital paradigm began some decades ago with the introduction of the microprocessor and the manipulation of information. The progresses of science and technology have been fantastic since those years, and due to these tremendous advances, the digital paradigm is in transitions today. Whereas the omnipresent importance of information for physical and living systems is not neglected, it is claimed that recent technological advances introduced a qualitative and quantitative change in the nature of how we handle information, thus placing these processes at the forefront of human activities. In this paper, we present a renovated and updated overview of the scope of the digital paradigm. We focus on the old ideas that make it possible, but also in the new ones that will show the new road.

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: The formulation for the radiation pattern and conductance of axial slots array antenna on a dielectric-coated elliptic cylinder is presented. The coating is assumed to be non-confocal. The analytical solution, given here, is based on the eigen function technique and the addition theorem of Mathieu functions. The excited apertures are assumed to generate a TM polarized wave. Accordingly, the obtained series solution is truncated to generate numerical results. Sample of calculated azimuthal radiation patterns and radiation conductance are presented for different antenna and coating parameters. The elliptic cylinder has one extra degree of freedom compared to a circular cylinder to control the radiation pattern and conductance. The computed results show the flexibility of the antenna to control the shape and direction of its radiation pattern by changing the frequency, the excitation, the coating thickness of the cylinder, and the constitutive parameters of the coat!

Abstract: A new approach based on the adoption of wavelet transforms is presented for the R point localization in ECG signals. The conceived real time signal processing technique, which uses a fast parallelized algorithm, has been evaluated adopting the standard MIT-BIH Arrhythmia database which includes specially selected holter recordings with anomalous but clinically important phenomena. In the procedure a soft thresholding technique is applied to dyadic scales in which the ECG signal is decomposed. Therefore, noise contribution is reduced and then signal is easily reconstructed in the time domain for further processing. Moreover, the tool analyzes the signal on different level wavelet representation at the same time showing a great parallelism degree and an enhancement in processing time. To evaluate the algorithm noise immunity, the MIT-BIH Noise Stress Test Database has been adopted containing baseline wander, muscle artifacts and electrode motion artifacts as noise so!
urces. The obtained performance shows the method validity in terms of algorithm speed up and characteristic parameter values. In fact, sensitivity and positive predictivity values of about 99.8% are obtained with a detection error rate of about 0.4%. Moreover, the conceived procedure gives satisfactory results also for ECG signals heavily corrupted by noise

Abstract: This paper shows a distributed simulation framework for tactical training in Networked Virtual Environment (NVE). These days the NVE technology for an operational tactical training system plays a significant role in military training courses. The existing military training simulation systems are mostly full simulated systems operating on single platform. They are to train individual¡¯s operation skill, but don¡¯t support team level tactical training. In order to train team level combat and command skill in dynamic battlefield, the interaction among distributed combat objects and diverse battlefield composition are required. This paper designs a distributed simulation framework to satisfy these requirements. The framework produces the networked virtual environment using virtual reality, event based simulation and HLA/RTI based interoperation techniques. This paper implements a small scale tactical training system based on the framework.

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.

Title of the Paper: New Aspects in Numerical Representations Involved in DNA Repeats Detection
Authors as they appear in the Paper: Petre G. Pop

Number of paper pages: 10
Abstract: The presence of repeated sequences is a fundamental feature of biological genomes. The detection of tandem repeats is important in biology and medicine as it can be used for phylogenic studies and disease diagnosis. A major difficulty in identification of repeats arises from the fact that the repeat units can be either exact or imperfect, in tandem or dispersed, and of unspecified length. Many of the methods for detecting repeated sequences are part of the digital signal processing field. These methods involve the application of a kind of transformation. Applying a transform technique requires mapping the symbolic domain into the numeric domain in such a way that no additional structure is placed on the symbolic sequence beyond that inherent to it. Therefore the numerical representation of genomic signals is very important. This paper presents results obtained by combining grey level spectrograms with two novel numerical representations to isolate position and leng!
th of DNA repeats.

Abstract: Abstract:- Ornithobacterium rhinotracheale (ORT) has been recently recognized as one of the respiratory pathogen in poultry. This bacterium produces clinical signs in chickens which are almost similar to the infection of Avibacterium paragallinarum, thus making diagnosis difficult. A collection of 18 isolates of O. rhinotracheale obtained from diseased chickens in Malaysia were characterized and their pathogenicity in embryonated eggs and chickens was investigated and compared to a reference strain. Antimicrobial susceptibility pattern of these isolates against seven antibiotics were determined using Kirby-Bauer diffusion test while minimal inhibition concentration (MIC) of tylosin and tilmicosin were performed using agar dilution method following the guidelines of Clinical and Laboratory Standards Institute. Biochemical and enzymatic tests results showed that the O. rhinotracheale isolates were made up of two variants that differ from the reference strain in their!
fermentation of arginine and glucose. Serotyping of these isolates revealed that all of the isolates were serotype A. Antimicrobial susceptibility test performed using antimicrobial disks showed that at least two of the isolates were resistant to more than three of the antibiotics tested. High (>128 ƒÝg/ml) minimal inhibition concentration (MIC) of tylosin and tilmicosin was observed in the isolates. Two representatives from these isolates were tested for their ability to cause mortality in egg embryos and their clinical manifestations in specific-pathogen-free (SPF) chickens. When compared to uninoculated embryos, these two isolates were found to cause significantly (P<0.01) higher number of embryo mortality. Infection of these isolates in SPF chickens caused growth retardation but no respiratory symptoms were observed. The results obtained in this study have provided some basic information on the properties of O. rhinotracheale that would be useful in diagnosing the dise!
ase. The understanding of its role in poultry health provides some inf
ormation that could be useful in implementing preventive measures against the disease.

Abstract: Abstract- For the multi-user application the multiple access interference (MAI) due to imperfect orthogonality between spreading codes induced by UWB dense multi-path significantly degrades system performance. Over the past few years, performance analyses for various UWB systems in an AWGN environment have been presented. However, those works did not consider UWB multipath effect; thus leading to an unacceptable analytical result. To compensate for the shortage of previous works, this research aims to theoretically derive accurate performance of DS-UWB system in the presence of AWGN, MAI, and multipath effect. The BER performance will be analyzed in terms of the number of active users. An upper bound on the maximum number of users supported by the system will be derived. In addition, the allowed multiple access transmission rate will also be evaluated.

Abstract: Disease diagnosis and treatment through gene expression analysis have become a widely used technique for genetecists around the world. Gene expression analysis can be done using DNA microarrays, which are based on the hybridization of a tissue's DNA sequence into a substrate and the further processing of the image conformed by the genes as green, red or yellow spots. The DNA microarray image processing involves, finding the location of the spots and the quantification of their expression level. This paper dicusses the steps needed to perform DNA microarray image analysis, such as: the spot addressing, spot segmentation and gene information extraction. Likewise, a tool that performs DNA microarray image analysis through the locations of the spots, based on the image projections and the identification of the spot signal using contour based segmentation, is described.

Abstract: This paper relates to the design and realisation of a high power (6000 A, 650 V) magnetic generator delivering ultra short (340 µs) high intensity (2 T) pulses. More than ten years of technical collaboration between two important graduate engineering schools of Bordeaux were necessary to carry out this project. This practical realisation was supported perfectly by the power electronics, electromagnetism and microprocessor courses given at ENSCPB and ENSEIRB graduate engineering schools. In the first place, we explain the educational interests of this realisation. Then, we give a detailed description of the system, including the tests which were used to check the specifications. Finally we conclude on possible uses of our equipment in biomedical research. As an illustration of bio medical applications, our apparatus was used for tests on living tissues (animal, bacteria, etc).

Abstract: Current technology of engineering has reached a level where lifecycle product information, comprehensive sets of model creation procedures, product data management, and Internet based communication environment serve integrated group work of engineers. It is inevitable, that the next main phase of development of the digital product definition is enriching content of product model in order to more intelligent decision support at product development. In this paper, the authors introduce a new methodology as a contribution to future intelligent modeling systems. Paper starts with a discussion on possibilities of enhanced product definition as a result of extension of current professional industrial modeling systems. Following this, a method is given for the description of associative features in product model. Next, description of associative features, extension of modeling by background content, as well as extension of product model for content constitute the main sec!
tions of the paper.

Abstract: Substation Automation Systems (SAS) are widely used for the purpose of control, protection, monitoring, communication etc. in substations to improve the reliability of the power supply. SASs adopting IT based solutions such as Ethernet LAN have recently become more common although hardwired control has been used in the past in earlier versions of SAS utilising simple communication methods. Moreover, IEC 61850 which is the international standard for communications within substations has been published, and the application of SAS based on IEC 61850 is increasing. It is necessary to select each component and the configuration of the SAS from the viewpoint of dependability so that the dependability of the SAS, i.e. reliability, availability, and serviceability may have a very big impact in the stability of the power supply in the electric power transmission and distribution systems. In this paper, we will describe the configuration policy of an IEC 61850 based SAS, its!
actual system configuration and the redundant configuration to improve dependability. In addition, we will explain some of the new functions not currently covered by IEC 61850 that we have developed to improve usability and availability. Following which we will present an evaluation of the dependability for MTTF (Mean Time To Failure), Availability, and FMEA (Failure Mode and Effects Analysis) for these configurations of SAS based on the dependability requirements for SAS. Furthermore, other measures have been adopted in the design to ensure fail-safe and fool-proof operation and thus improve system dependability in a much wider sense.

Abstract: A method for the estimation of the state-of-charge in lead-acid batteries for electric vehicles is investigated. The electrochemistry theorem is introduced to measure the resistance effect of the electrode reaction and to estimate the internal energy loss and the electrolyte specific gravity in batteries. The proposed algorithms can accuracy compute the state-of-charge of the lead-acid batteries, that the variations of the electrochemical resistance in the electrolyte concentrations are estimated for the state-of-charge. The approach is based on the idea of constructing the real time approach that can be implemented by a digital signal processor. The motivation of this work is to explore the problem of different procedures on the charged and discharged of the lead-acid batteries to obtain the variations in the charge-discharge and resistance profiles. The provided method shows that it is validated for estimation the capacitances and residue energies.

Abstract: The objective of this paper is to design and implement a chassis dynamometer for testing dynamic characteristics of a battery-powered motorcycle (BPM). By using a load simulation system, which is constituted with a DC motor and two rollers, a roller of the test platform is connected to a DC motor through a torque sensor, and a controller is designed to control the DC motor to simulate driving resistance produced when the BPM runs on various roads. The test platform can simulate each drag force when the BPM is in acceleration or in a constant-speed drive, and also can simulate kinetic energy gained by the BPM when braking, deceleration and running downhill. A computer not only controls the test platform but also collects signals from sensors on the test platform and the BPM, and can analyze related data such as driving resistance, driving range, speed, kinetic energy recycle and so on. The test platform has an integral steel structure and a stable center of gravity,!
and the height and length adjustment of the machine is convenient and as well the test is easy to perform, thus it can provide efficient tests on battery-powered motorcycles (BPMs) which are currently popularized by all circles with great efforts, so as to achieve the objective of performance measurement, performance analysis and data collection. From experiment results, the BPM performance test platform can simulate various road patterns and complete an automatic testing process.

Title of the Paper: Changes in Fluctuation Waves in Coherent Airflow Structures with Input Perturbation

Email addresses of all the authors: omarzouk@vt.edu
Number of paper pages: 23
Abstract: We predict the development and propagation of the fluctuations in a perturbed ideally-expanded air jet. A non-propagating harmonic perturbation in the density, axial velocity, and pressure is introduced at the inflow with different frequencies to produce coherent structures in the airflow, which are synchronized with the applied frequency. Then, the fluctuations and acoustic fields are predicted for each frequency by integrating the axisymmetric linearized Euler equations. We investigate the effect of the perturbation frequency on different characteristics of the pressure and velocity waves. The perturbation frequency can be used to alter the propagation pattern and intensity of the waves and mitigate the noise levels at certain zones.

Abstract: Hydroenergetic works represent the major climate and ventilation problems in the rooms where they are made. The air temperature of these rooms is determined by two elements: the warmth that emanates from the massif, especially in great depths, and the humidity of air, which is seldom close to saturation. This paper studies these two elements solving the problem of parameter interaction (temperature - humidity) from an analytical point of view. The analytically obtained equations are experimentally validated through a case study.

Abstract: Multiple radar system and spread spectrum communication system can fundamentally improve the system performance by using a group of specially designed orthogonal signals. A Modified Simulated Annealing Algorithm (MSAA) is proposed as a statistical technique for obtaining approximate solutions to combinatorial optimization problems. The Proposed algorithm is a combination of Simulated Annealing and Hamming Scan algorithms. MSAA is used to design orthogonal eight-phase sequence sets, which have good autocorrelation and crosscorrelation properties. Some of the synthesized results are presented, and their properties are better than four-phase sequence sets known in the literature. The synthesized eight-phase sequence sets are promising for practical application to multiple Radar system and spread spectrum communication. The convergence rate of the algorithm is shown to be good.

Abstract: Teaching conceptual and qualitative material effectively while leveraging the contents efficiently has been an elusive goal for many computer aided learning (CAL) packages in the past. With the advent of newer technologies such as multimedia and virtual reality these technologies are being researched and applied to various areas of educational settings, especially in science and technology. However the potential of these technologies has not been fully exploited, particularly in the teaching of engineering. In this research an innovative approach based on the principle of CAL is used to design and implement integrated packages known as Technology Assisted Problem Solving or TAPS packages, which guide students step-by-step to complete various Engineering Mechanics problems. Since the use of CAL in higher learning institutions in Malaysia is still at its infancy, this research is mainly concerned with the development of effective TAPS packages in supplementing the te!
aching and learning of Engineering Mechanics. The TAPS packages were structured according to the learners' needs based on the survey carried out using the Felder-Solomon's ILS questionnaires and the packages were evaluated using quantitative techniques for its effectiveness. Four groups of learners were identified i.e. sensory, visual, active and sequential. The results showed that different group of learners have different preferences of the features offered in the TAPS packages. Nevertheless, the study found that the step-by-step approach which was integrated in each of the four TAPS packages was beneficial in promoting learning and understanding of Engineering Mechanics concepts, particularly to slow learners.

Abstract: There are number of systems, such as transport and logistic, power and telecommunication, hydropower and nuclear power stations; that are critical systems for the functioning of day-to-day life of the society in Finland. When assessing possible risks, it is only seldom taken into account that power, hydropower and nuclear power plants are critically dependent on the reliability and security of information systems. Information security is often enhanced by purchasing and extending technical solutions without considering any systematic planning and knowledge of how to protect the different segments of the system. In this case study, the risk is not only to investing of the information security resources to the wrong targets but also to take more risks. As the unplanned integration of systems and the related information security components may even create new security risks. As a result, systems that are critical for society may not work as they should. The Rescuing o!
f Intelligence and Electronic Security Core Applications (RIESCA) project is targeted to do contributive and constructive solutions to this problem. The research object is produce information security and continuity management methods that can be used to ensure the proper functioning of critical systems under varying circumstances. Furthermore, it also leads to the development of an integrative action and environment for critical systems development, management and evaluation. This study: (1) describes the RIESCA project; (2) proposes enhanced data mining collection and analysis architecture model for critical systems evaluation; (3) includes Business Continuing Management (BCM) method creation perspective to context of critical systems and (4) describes the RIESCA action and process implementation model.

Abstract: An essential element when establishing the balance of a bucket wheel excavator is the determination of the barycentre, the best results being thus obtained by weighting after having installed all the components. The problem, on which emphasis is laid, is how to maintain the stability and equilibrium of bucket wheel excavators or any other extraction machinery during operation, the main machinery of a technological extracting system employed for coal mining. The balance survey, respectively that of the stability of these machineries is compulsory because the bearing surface is rather small compared to the other building sub-systems outside the range of the surface, onto which much higher forces operate. The lack of correct balance for bucket wheel excavators determines their operation in an inadequate dynamic mode, or in extreme cases, there is the danger of losing stability by tilting over the excavator respectively suffering huge material and human loss. It is com!
pulsory to verify for the correctness of the position and mass value of balance because there might be substantial error sources leading to compromise the operation. One of the most popular methods is that of weighting the entire equipment from the superior platform of the excavator. The weighting process implies the lifting of the excavators in three spots with hydraulic cylinders, the measurement of the forces, as well as the measurement of pressure inside the cylinders and of the stroke of each cylinder. The data measurement and rehashing installation is destined to determine the dimensions that finally define the weighting process of excavators or other operating machineries to which the balancing and control of stability is imposed. Thus, two types of data measurement and rehashing installations depending on the nature and type of the transducer used will be presented. For the first type, only analogical signals are transmitted to a numerical computer, and for the seco!
nd type only digital signals are transmitted.

The sensed data need to be delivered with some real-time constraints, such as end-to-end deadlines. Since the data communication model is different from the traditional wireless ad hoc networks or any centralized systems, different solutions have been proposed, such as real-time sensitive routing protocols, data packet prioritization, and real-time scheduling. Most of these solutions prioritize packets at the MAC layer according to their deadlines and distances to the sink. Packet prioritization by itself cannot completely support real-time data communication requirements. In our work, we develop Simple and Efficient Scheduling Scheme in Sensor Networks (SES-SN), in which packet scheduling, queuing as well as routing are considered. This scheme efficiently utilizes the limited energy and available memory !
resources of sensor nodes and also has a significant impact on the success of real-time sensor data communication and avoids collision.

Abstract: In order to detect and identify the defects on GIS, the ultra-high frequency envelope detection circuit and high-speed data acquisition system was designed, and the tests of five typical defects for GIS were made in the laboratory and the envelope signal was acquired based on Ultra-high frequency (UHF) envelop detection circuit. A large number of experiments show that time-domain characteristics of partial discharge signals generated by the same defect model are about the same, envelopes are nearly identical too. The time-domain characteristics of partial discharge signals generated by different defect models are different, and their envelope shapes are different too. A new method of pattern recognition was proposed which analyses the characteristic parameters of the envelope signal at time-domain with BP neural network. A large number of test data in Lab indicate that the method is effective.

Abstract: - This paper presents a study of the sensitivity analysis of the artificial Hopfield Neural Network (HNN) when segmenting natural color images. The color distinction or vision system relies on two step process which, first classifies the different regions in the scene into a given number of clusters, and then assigns to each cluster a color that is likely to one of its corresponding region in the raw image. The classification process is performed using the minimization of an energy function typically the Sum of Squared Errors (SSE). The optimization process is found sensitive to the step taken by the network in its way to the global minimum. The color assignment to the clusters is performed based on combination of information from the color palette used in the raw image and the last distribution of the pixels among clusters. Applying the system to a gold standard color image, the results show that HNN natural color segmentation accuracy can be significantly improve!
d if we control its step size when modifying its weights between its neurons after each iteration. The color matching process shows a lot of consistency when tested with natural color images as shown in the results presented here.

Title of the Paper: Probabilistic Methods for Ranking Sources of Error
Authors as they appear in the Paper: Nataniel Greene
Email addresses of all the authors: ngreene.math@gmail.com
Number of paper pages: 10
Abstract: A classical method for ranking n potential events as sources of error is Bayes' theorem. However, a ranking based on Bayes' theorem lacks a fundamental symmetry: the ranking in terms of blame for error will not be the reverse of the ranking in terms of credit for lack of error. While this is not a flaw in Bayes' theorem, it does lead one to inquire whether there are related methods which have such symmetry. Related methods explored here include the logical version of Bayes' theorem based on probabilities of conditionals, probabilities of biconditionals and ratios or differences of credit to blame. We find that of all the methods described, probabilities of biconditionals and a corresponding notion of logical correlation coefficients provide a particularly attractive method for ranking blame for error and credit for lack of error which has the symmetry property we are interested in.

Abstract: Applications of biological methods and systems found in nature to the study and design of engineering systems and modern technology are defined as BIONICS. The present paper describes a bionics application of shape memory alloy in construction of orthopedic implant. The main idea of this paper is related to design modular adaptive implants for fractured bones. In order to target the efficiency of medical treatment, the implant has to protect the fractured bone, for the healing period, undertaking much as is possible from the daily usual load of the healthy bones. After a particular stage of healing period is passed, using implant modularity, the load is gradually transferred to bone, assuring in this manner a gradually recover of bone function. The adaptability of this design is related to medical possibility of the doctor to made the implant to correspond to patient specifically anatomy. Using a CT realistic numerical bone models, the mechanical simulation of diff!
erent types of loading of the fractured bones treated with conventional method are presented. The results are commented and conclusions are formulated.

Abstract: In this paper, a high accurate positioning technique is proposed for autonomous underwater vehicle(AUV). It needs not position correction from Global Position System (GPS) above the sea surface and short- or long-baseline acoustic positioning system(SBL or LBL) under the sea. Two long time experiments gave maximal and average deviations are less than 33.6m and 15.1m; respectively. Position deviations are verified by tracking datum of a long-baseline acoustic position system with post navigation processing datum. These deviations are much less than the tracking range of sonar. High accurate positioning results let vehicles have less supporting from launching vessel and give flexible and mobile operations.

Abstract: This paper presents a comparative analysis of three current decomposition methods in three-phase systems without neutral wire on the basis of some case studies. The analysis takes into consideration the Currents' Physical Components (CPC) introduced by Professor Czarnecki in 1988 [1], the active and the reactive components of the p-q theory of the instantaneous power introduced by Professor Akagi and his coauthors in 1983 [2] and a modified variant of the Akagi's components proposed by the authors for the operation under unbalanced or nonsinusoidal conditions [3]. We propose four components of the current space-vector in terms of DC and AC components of the instantaneous active and reactive powers. The term of supplementary useless current vector is also pointed out. The analysis shows that the current decomposition which respects the definition of the instantaneous apparent power vector is useful for compensation reasons only if the supply voltages are sinusoidal.!
A modified definition of the components of the current is proposed for the operation under nonsinusoidal voltage conditions. This case studies based-analysis allows finding again some deficiencies that Professor Czarnecki has pointed out relating to Akagi's current decomposition [4], [5]. It is shown that the proposed active and reactive current components are identical to those of Czarnecki's CPC theory.

Abstract: In the paper, a programmable phase-locked loop (PLL) based ISM band fractional-N frequency synthesizer, commonly used in wireless communication system, is presented. The third order error-feedback Delta-Sigma modulator and high linearity offset phase frequency detector (PFD)/ Charge Pump (CP) are adopted to reduce close-in phase noise due to quantization noise folding. Automatic calibration technique is also introduced to select the optimal frequency sub-band of voltage controlled oscillator (VCO) automatically through process, voltage and temperature (PVT) variation. The Synthesizer is designed in UMC .18um RF process and has a die size of 1.5mm*2.3mm. The measured phase noise is -112 dBc/Hz at 1 MHz offset.
