Abstract: There are many research efforts for improving bandwidth management in wireless communication systems based mainly on DCA (Dynamic Channel Allocation) Schemes designed and evaluated through various Simulation models which, however, use a common simulation model architecture coming from queuing theory. Although much attention has been paid to Channel Allocation Mechanisms there are few only efforts related to the corresponding simulation models. These models consist of various critical components including network services models and the simulation model architecture organizing network events scheduling, network events handling and network performance evaluation. One of the most critical components is the event scheduling mechanism, which reflects network events as they happen in a real network and which has not been investigated in depth regarding its performance. The state of the art event scheduling mechanism called Calendar Queue (CQ) schedules events for later e!
xecution based on the corresponding time stamps of each generated event. The major drawback of this approach is that the generated events are executed only sequentially due to progressive time stamps. On the other hand, events in a real wireless network happen concurrently and so the state of the art mechanism can not reflect such conditions. The goal of this paper is to propose an alternative novel real time scheduling mechanism based on a synthesis of multitasking theory and queuing theory techniques, which could be involved in generating and investigating a new generation of event scheduling algorithms suitable for simulation modelling of cellular networks bandwidth management. This mechanism is analyzed through multitasking theory tools and is shown to face effectively the concurrent nature of the generated network events providing an efficient solution to the Calendar Queue problem.

Abstract: Inspection offers an opportunity to detect and remove defects at various points during software development. Early detection will reduce the effect of propagation and amplification of defects into the later phases of software development. Collaborative inspection on the web aims to eliminate the time factor needed to assemble the inspection or review team at a physical location. Through the collaborative mode, software teams can perform software inspection and review from geographically separated places asynchronously. These newly introduced practices have proven that collaborative inspection and review of artifacts on the web is feasible. This paper provides a model for collaborative inspection and review including possible features of model and tool that will support collaborative inspection and review on the web.

Abstract: The structure of software systems is subject of many changes during the systems lifecycle. A continuous improvement of the software systems structure can be made using refactoring, that assures a clean and easy to maintain software structure. In this paper we are focusing on the problem of restructuring object oriented software systems using hierarchical clustering. We propose two hierachical clustering based algorithms which takes an existing software and reassembles it using clustering, in order to obtain a better design, suggesting the needed refactorings. We evaluate the proposed algorithms using the open source case study JHotDraw and a real software system, providing a comparison with previous approaches.

Title of the Paper: 'No Representation without Information Flow' - Measuring Efficacy and Efficiency of Representation: An Information Theoretic Approach

Abstract: Representation is a key concept for semiotics and for information systems. Stamper's framework may be seen outlining what is required for the efficacy of signs in standing for (i.e., representing) something else in an organization, among many others. We explore how the efficacy and the efficiency of representation may be measured, which seems overlooked in available literature of information systems and organizational semiotics. And we approach this problem from the perspective of what we call the 'information carrying' relation between the representation and the represented. We model the represented as an information source and the representation an information carrier, and the 'representing' relationship between them as that of 'information carrying'. That is, information is carried and therefore flows. These then are further modeled mathematically as random variables and random events, and a special relationship between random events. This approach enables us to!
reveal a necessary condition for the efficacy and the efficiency of representation, and to measure it. To this end we extend Dretske's semantic theory of information. The conviction that we put forward here is 'No representation without information flow', based upon which the efficacy and efficiency of a representation system may be measurable.

Abstract: While bandwidth management in cellular communication systems has been thoroughly examined for voice channel admission by developing several DCA (Dynamic Channel Assignment) strategies, there are a few only efforts investigating assignment and management of multimedia enabling channels in wireless communications. However, the increasing demand for these advanced services in cellular networks such as data, MMS and video transfers raises the problem of efficient bandwidth management in terms of channel assignment meeting QoS criteria. Several algorithms for supporting QoS services have been presented in the literature based mainly on bandwidth reservation and capacity management for enabling efficient handoff over cellular networks. The goal of this paper is to develop and investigate, however, novel integral DCA algorithms for supporting data (e.g. files) and video (video viewing, video conference) transmission with Quality of Service (QoS), and their evaluation thro!
ugh a prototype advanced statistical simulation environment for cellular communications. Moreover, we analyze the dynamic and distributed channel allocation strategies for enabling advanced multimedia services based on signal purity measures and interference measurements. Finally, the performance of these suggested algorithms evaluated through a proposed prototype simulation environment is discussed.

Abstract: This paper implements an Artificial Neural Network (ANN) model able to determine the internal temperatures in a squirrel-cage three-phase induction motor fed by an inverter. A sinusoidal pulse-width modulation (SPWM) inverter feeding three-phase induction motors were tested up to over load. The temperatures are measured in a node of stator winding. The results show that the artificial neural network model produces reliable estimates of interior temperature of stator winding. Through this model, it is possible to determine the temperatures in the tested motors and to analyze the influence of the fundamental frequency voltage on steady state temperatures and motor performance limitation, specifically the maximum acceptable load, so that the motor does not exceed its normal steady state temperature when is supplied by an inverter.

Abstract: The aim of this paper consists in developing a model for realistic calculation, but at the same time not a very complicated one, in order to determine the operating parameters of a rocket engine with solid propellant (RESP). The model results will be compared with experimental results and the quality of the model will be evaluated. The study of operating stability RESP will be made accordingly to Liapunov theory, considering the system of parametric equations perturbed around the balance parameters. The methodology dealing with the stability problem consists in obtaining the linear equations and the verification of the eigenvalue of the stability matrix. The results are analyzed for a functional rocket engine at low pressure, which has the combustion chamber made of cardboard, engine used for anti-hailstone rocket. Two representatives cases will be take in to consideration and analyzed from the point de view of burn parameters, one of them for stable conditions and!
other for instable conditions. For both cases a complete analysis will be done and the results will be compared. The novelty of the work lies in the technique to tackle the stability problem for the operation of rocket engines at low pressure, many of them representing specific applications for civil destination.

Abstract: The paper describes the physical backgrounds for modelling in visualisation using computer graphics software and in programs of radiative heat exchange. Physical phenomena in both cases (generation, propagation, reflection and absorption of light and radiative heat flux) are quite similar, provided with basic equations, typical simplification assumptions and the most frequently applied methods of resolving such issues. Various models applied in radiative heat transfer and computer graphics software are compared. The similarity and differences of algorithms for both tasks are determined and replaceability conditions are enumerated. Formulas are provided to convert thermal boundary values (temperature and power density) into luminous or radiant quantities (luminance) and vice versa. A possible scope of shared computations is also outlined.

Abstract: This paper proposes the practical method for MW- redispatching and identifying wheeling paths taking transmission line constraint into account based on an extended sensitivity analysis. Because the decision for the MW- dispatch/ scheduling is requested to be very fast, the method proposed here brings the efficiency of computations by utilizing the existing practical approaches for obtaining the optimal solution. So, in this paper, a method of MW- redispatching by using the practical sensitivity-based technique, which is used for identifying the wheeling paths in overloaded states is proposed. By the proposed method, the MW- redispatching problem without using OPF solutions can be solved. On the other hand, in deregulated electricity markets, appropriate and efficient levying of the wheeling rate is one of the critical issues. It is obvious that if wheeling paths from suppliers to customers could be identified appropriately, it becomes possible to set up the proper !
and fair wheeling rate according to the degree of power flow in each wheeling path. Until now, we have reported that it is possible to identify paths of the wheeling in any situation effectively by making use of the sensitivities calculated by an extended sensitivity analysis. In the previous research based on the sensitivity analysis, constrains on transmission lines have not been taken into consideration. Then, in this paper, the method of identifying wheeling paths is presented taking transmission line constrains into account based on an extended sensitivity analysis. In order to show the validity of the proposed method, a series of simulations on the IEEE 30-bus test system are conducted and numerical results are demonstrated.

Abstract: Rain gauge networks are used to calibrate and validate quantitative precipitation estimation (QPE) methods based on remote sensing, which may be used as data sources for hydrologic models. The typical approach is to adjust (calibrate) or compare (validate) the rainfall in the QPE pixel with the rain gauge located within the pixel. The QPE result represents a mean rainfall over the pixel area, whereas the rainfall from the gauge represents a point, although it is normally assumed to represent some area. In most cases the QPE pixel area is millions of square meter in size. We hypothesize that some rain gauge networks in environments similar to this study (i.e., tropical coastal), which provide only one rain gauge per remote sensing pixel, may lead to error when used to calibrate/validate QPE methods, and that consequently these errors may be propagated throughout hydrologic models. The objective of this paper is to describe a ground-truth rain gauge network loca!
ted in western Puerto Rico which will be available to test our hypothesis. In this paper we discuss observations from the rain gauge network, but do not present any QPE validation results. In addition to being valuable for validating satellite and radar QPE data, the rain gauge network is being used to test and calibrate atmospheric simulation models and to gain a better understanding of the sea breeze effect and its influence on rainfall. In this study, a large number of storms (> 60) were evaluated between August 2006 and August 2008. The area covered by the rain gauge network was limited to a single GOES-12 pixel (4 km x 4 km). Five-minute and total storm rainfall amounts were spatially variable at the sub-pixel scale. The average storm rainfall from 20% of the 120 possible rain gauge-pairs was found to be significantly different at the 5% of significance level, indicating significant rainfall variation at the sub-pixel scale. The average coefficient of deter!
mination (r2), describing the goodness of fit of a linear model relati
ng rain gauge pairs, was 0.365, further suggesting a significant degree of variability at the satellite sub-pixel scale. Although there were several different storm types identified (localized, upper westerly trough, tropical easterly wave, tropical westerly trough, cold front and localized with cold front), there did not appear to be any relationship between storm type and the correlation patterns among the gauges.

Abstract: Abstract: - In the present study, the torque-twist behavior of non-linear pile-soil system related to the wave-current loading on Jacket type offshore platform is investigated. The non-linearities of pile-soil with respect to both depth and the twist angle of pile are considered. The basic differential equilibrium equations of the pile-soil system are derived based on hyper- elasticity theory of soil. A numerical central finite difference method is applied based on simplification of stress field around the pile elements which takes into account changes in the secondary shear stress components and also non-linearities due to non-homogeneous soil condition. This method uses a one-dimensional mesh along pile-soil interface. It also takes into account the changes in G of soil with respect to the twist angle of pile. In a separate work, the simulated torque-twist behavior of pile-soil system based on this analysis approach is compared with the res!
ults of more refined finite element analysis by using continuum mechanics theory and also full scale pile-soil test results (Emami,2002). The torque-twist results by using the proposed approach have been used to study the behavior of two jacket-pile-soil systems under sea environmental and accidental loading.

Number of paper pages: 10
Abstract: In this paper, we first describe the pedagogical reform process in our school. Then, we point out the major human difficulties in reforming. The complexity of the relation between the new student generation and the teachers is briefly described. And some major changes in student's behaviour are given as example. The consequences on the teaching strategy are then indicated. At least, we show that theses evolutions require adaptation, efforts and changes in the way of teaching. And we finally present here, in our field of competence, a concrete and pedagogical robot design project (with technical details) we did, as an answer to the reform necessity.

Abstract: Abstract: - Professional Construction Management (PCM) is a burgeoning service profession for public construction in Taiwan. But in fact, in present condition, no matter how good or bad the service performance is, the PCM consultant still charges a fee in accordance with the project progress. It is very hard to quantify the achievement and mete out a proper judgment for the PCM service performance, especially in the design stage that most affects the overall project achievement. To deal with the above problem, this study investigates owner opinions and thereby establishes the representative performance indicators of PCM design service. Then it successfully combines the Fuzzy theory and the Data Envelopment Analysis (DEA) method, so as to construct a fuzzy effectiveness analysis approach to evaluating PCM service performance in the design stage. The approach can offer a listed rank and class of design service performance in construction projects, and further provide!
s a simple appraisal table, so that the owner can quickly and effectively evaluate the PCM design service performance. Finally, through the case studies, this approach is verified to be reasonable and acceptable in practice. It can be an effective tool to measure the PCM design service performance and can help owners to evaluate and choose PCM consultants in the design stage.

Abstract: In this paper, we consider Bayesian analysis proposed by Bretthorst for estimating parameters of the corrupted signals and incorporate it with a simulated annealing algorithm to obtain a global maximum of the posterior probability density of the parameters. Thus, this analysis offers different approach to find parameter values through a directed, but random, search of the parameter space. For this purpose, we developed a Mathematica code of this Bayesian approach and used it for recovering sinusoids corrupted by random noise. The simulation results support the effectiveness of the method.

Abstract: In this paper, we propose a new Tree Based Interleaver (TBI) to generate different chip-level interleaving sequences for different users in an IDMA system, which reduces computational complexity. This method of generation also solves the memory cost problem and reduces the amount of information exchange between mobile stations and base stations required to specify the interleaver. Simulation results are presented to show that the proposed interleavers perform well as compared to Random Interleavers in an IDMA system.

Abstract: In risk management for software projects, risk factor identification is an important and yet difficult task. It would seem that contemporary risk identification methods, in essence, are concerned with collection and processing of information. We observe that there is normally an informational relationship between risk factors, and therefore, it is plausible to think that risk identification involves the concept of 'information content', which captures and formalizes the intuitive idea that one factor carries information about another. This point seems being overlooked thus far. We propose an approach that is based upon reasoning about information content of risk factors for identifying essential factors whereby to facilitate risk evaluation.

Abstract: The work we describe here is aimed at assisting out-patients affected by insulin dependent diabetes mellitus with an advisory/control algorithm. This advisory/control algorithm incorporates expert knowledge about the treatment of this disease by using Mamdani type fuzzy logic controllers to regulate the blood glucose level (BGL) when the diabetic patient is subjected to a glucose meal disturbance or fluctuations in the measured glucose level due to error in the measuring instrument. We proposed two-level architecture for control system. The goal of the Low Level Module is to suggest the next insulin dosage of both short and intermediate acting insulin (Regular and NPH) formulation that are programmed in a three-shot daily basis before meals, depending on the blood glucose measurement. The combined preparation is then injected by the patient through a subcutaneous route. The High Level Module adjusts the maximum amounts of insulin provided to the patient in a time-s!
cale of days. This module aims to work as a supervisor of the low level module. Simulations are illustrated, using a flow-limited model for diabetes mellitus based on the work of Puckett.

Abstract: This paper analyzes the parameters that determine and affect the environmental quality of urban roads. These parameters are grouped in five categories: bio-climatic, urban planning, traffic parameters, artificial elements and other parameters. After theoretically analysing all the parameters of the above categories, they are tested in practice for 16 representative roads of the urban complex of Heraklion. Following this, we compare the results of the above-mentioned analysis that can be quantified and draw certain conclusions for the current environmental quality of the roads examined and, by extension, for all the roads of the urban complex of Heraklion. Based on these conclusions, we propose certain interventions for upgrading the environmental quality of the city's roads that are of relevance to the state, as well as to the private sector.

Abstract: Contrarily to big firms, small firms interact intensively with the territory in which they located, as a signal of their embeddedness. The particular tight links they develop with their external environment reduce uncertainty risks. In general, for them, geographical and sociological proximities constitute the main sources of assets and information determining their perspectives and strategic choices. The present study uses a set of enquires, developed within the framework of a European research project, with the purpose of modelling the determinants of innovation in a bi-univocal relationship of interdependencies between small firms and their environmental contexts. We dealt mainly with lagging regions and a panel of 323 firms from the agro-food sector, located in 11 different European rural regions from six different countries. Using a set of variables able to characterise the innovative processes and through the application of k-mean clusters statistical analysi!
s, it was possible to detect behavioural patterns towards innovation among those firms. Non-innovators, pioneer innovators and follower innovators were the identified patterns. Using cross tabs analysis between those patterns and a set of attributes dealing with the importance of human capital, the profile of each group were drawn.

Title of the Paper: Portuguese agriculture in the last decade: GIS as an evaluation tool
Authors as they appear in the Paper: Eric de Noronha Vaz , Teresa de Noronha Vaz
Email addresses of all the authors: mtvaz@ualg.pt
Number of paper pages: 10
Abstract: A common spatial database was born in the mid eighties to assess a real view of the spatial physical environment. This dataset inventory made for the whole Europe was designated as CORINE Land Cover and contains an overall inventory with classifications of artificial areas, agricultural areas, forests and semi-natural areas as well as wetlands. For practical reasons, CORINE has been much used since the upcoming of the second version of the database (CORINE 2000) to assess dynamics of land use changes. In this paper, aiming to better understand the structural change occurred in rural environments, tools such as Geographic Information Systems (GIS) have been used to observe and track the Portuguese rural areas and find out how they follow the evolution of the agricultural sector and the application of the Common Agricultural Policy (CAP). The proposed comparison between the database CORINE Land cover 90 and CORINE Land cover 2000 allows results for European, nation!
al, regional or local levels. However, our study concentrates on the Portuguese data to evaluate the results of the last decade agricultural policy in the country. The subdivision of agricultural areas into arable land (non-irrigated arable land, permanently irrigated land, rice fields), permanent crops (vineyards, fruit trees and berry plantations, olive groves), pastures, heterogeneous agricultural areas (annual crops associated with permanent crops, complex cultivation, land principally occupied by agriculture, with significant areas of natural vegetation, agro-forestry areas) is possible and is used to draw a dynamic comparison and access the exact impacts of change. This overview of how the decision making processes resulted in the case of the Portuguese agricultural sector can be disaggregated by sector and region, challenging questions such as: which are the trade-offs of rural activity among the different sectors and regions? How does it cope with small cities? Whic!
h activities / strategies are best adequate for the compromise between
rural and urban dichotomy?

Abstract: Abstract: Fertilization is one of the main factors affecting the yield and quality of kiwifruit (Actinidia deliciosa). Therefore, suitable cultural practices, including fertilization, should be studied in order to guarantee high production levels and the maintenance of fruit quality. On the other hand, physiological disorders during fruit storage are common, leading to important losses of marketable yield and can be strongly affected by the mineral composition of fruits. This study lasted for 3 years (2004 to 2006) and experimental data was obtained from a fertilizer trial arranged into completely randomized blocks, with three replications, installed in an orchard located in the Portuguese Region of Bairrada (central Portugal). This experiment was established in order to evaluate the influence of nitrogen and potassium fertilization on the yield and fruit quality of kiwifruit cv. Hayward. Three levels of nitrogen (30, 60 and 90 kg ha-1N) and four levels of potassiu!
m (0, 45, 90 and 135 kg ha-1 K2O) were used, arranged into 12 experimental treatments. Since 2004, nitrogen and potassium were applied annually. The total yield of each plot was evaluated and fruits were graded into six categories according to the weight and deformations: fruits <65g, 65-75g, 75-85g, 85-105g, >105g and deformed fruits. After harvest, fruits were stored in normal atmosphere at 0ºC and 90-95% hygrometry conditions. After 50 days of storage, one sample of each experimental treatment consisting of 10 fruits from 85-105g size was taken to assess some quality parameters namely, firmness of the pulp, titratable acidity, and soluble solids content, at harvest. Other sample of 16 fruits of each marketable fruit size (65-75g, 75-85g, 85-105g and 105 g) was taken from each plot and analysed for its mineral composition (N, P, K, Ca, Mg, S, Na, Fe, Mn, Zn, Cu, and B).The present paper reports a first set of experimental results of a study with the main propose of establ!
ishing the effect of nitrogen and potassium fertilization on yield, fr
uit quality and fruit mineral composition of Actinidia deliciosa 'Hayward' at 50 days after storage, corresponding to the experimental period 2004 to 2006. Results showed a significant mean effect of interaction NxK fertilization on fruit yield. The annual mean application of 60 kg ha-1 N, with the highest rate of potassium, 135 kg ha-1 K2O, led to the highest level of marketable fruit yield (19.1 tonnes ha-1). The acidity and soluble solids contents of fruits were not affected by nitrogen and potassium content supply. However, both nutrients decreased the flesh firmness. The interaction NxK fertilization influenced fruit calcium concentration. The lowest level of calcium was observed with 90 kg ha-1 N associated with 90 kg ha-1 or 135 kg ha-1 K2O. Both N/Ca and K/Ca ratios increased with nitrogen and potassium supply.

Abstract: In this paper an approach based on the use of different frame lengths for the feature extraction process in the training and recognition phases of a speaker verification system is presented. It is able to sensibly reduce the ER and the degradation on performance related to the training/verification feature mismatch. The potentiality of the approach are investigated in an a-posteriori search of the best combination to be adopted. A prototype of an expert system is also presented in order to automatically search, in real time operating conditions, the optimal combination of parameters. Tests have been performed on a set of speakers whose speech productions were spanned over approximately 3 months.

Abstract: Validation of the Hydro-Estimator (HE) and the Next Generation Radar (NEXRAD) during heavy storms over Puerto Rico (PR) is reported. The HE is a high resolution rainfall retrieval algorithm based on satellite and numerical weather prediction model data. The accuracy of the HE and the NEXRAD rainfall estimates can be measured by decomposing the rainfall process into sequences of discrete (rain / no rain) and continuous (rainfall rate) random variables. Validation results are based on five heavy storms that seriously impacted human life and the economy of PR during the period 2003 to 2005. The average discrete validation results indicate acceptable hit rate values for both the HE and NEXRAD (0.76 vs. 0.87) and reasonable discrete bias ratios (1.04 vs. 0.73) but a very low of probability of detection of rain for both the HE and NEXRAD (0.36 vs. 0.52). The HE shows an overestimation on average whereas the NEXRAD exhibits underestimation in the continuous validatio!
n results (continuous bias ratio of 1.14 vs 0.70 for NEXRAD), which contributes to moderate overall errors for the HE and NEXRAD in terms of root mean squared error (2.14 mm vs. 1.66 mm) and mean absolute error (0.96 mm vs. 0.77 mm). The HE algorithm was designed to operate over US continental areas and satisfactory results have been reported. However, over tropical regions it was determined that warm clouds can generate substantial rainfall amounts that are not detected by the HE algorithm. It is known that precipitation processes in clouds with warm tops are very sensitive to the microphysical structure of their tops. Specifically, precipitation processes are more efficient when water droplets or/and ice particles grow to larger sizes. It has been shown that the uses of the reflected portion of the near-infrared during the daytime indicates the presence large cloud-top particles and suggest rain in warm-top clouds. It has been used the effective radius of clouds parti!
cles to detect raining clouds. However, the available algorithms to e
stimate the effective radius are designed to operate over ice clouds. We are in the process of developing an algorithm to extract the microphysical structure for rainy warm top clouds, and the first step of this algorithm is to estimate the emittance of near infrared window, which is described in this paper.

Abstract: Mobile agents have attracted considerable interest in recent years . In the context of mobile agents , fault tolerance is crucial to enable the integration of mobile agent technology into today,s business applications. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. For this purpose, we first identify two basic requirements for fault-tolerant mobile agent execution: (1) non-blocking and (2) exactly-once. In this paper, we propose a fault-tolerant model for mobile agents executing in large distributed networks and analyze the life expectancy of mobile agents in our model. The key idea is the use of stochastic regularities of mobile agent's behavior-all the mobile agents in the network as a whole can be stochastically characterized though a single mobile agent may act randomly.Our analytical results reveal new theoretical insights into the statistical behaviors of mobile agents and provi!
de useful tools for effectively managing mobile agents in large networks.

Abstract: The reliable execution of a mobile agent is a very important design issue in building a mobile agent system and many fault-tolerant schemes have been proposed so far. Security is a major prob¬lem of mobile agent systems, especially when money transactions are concerned . Security for the partners involved is handled by encryption methods based on a public key authentication mechanism and by secret key encryption of the communication. In this paper, we examine qualitatively the security considerations and challenges in application development with the mobile code paradigm. We identify a simple but crucial security requirement for the general acceptance of the mobile code paradigm, and evaluate the current status of mobile code development in meeting this requirement. We find that the mobile agent approach is the most interesting and challenging branch of mobile code in the security context. Therefore, we built a simple agent-based information retrieval application!

Abstract: The reliable execution of a mobile agent is a very important design issue to build a mobile agent system and many fault-tolerant schemes have been proposed. Hence, in this paper, we present evaluation of the per¬formance of the fault-tolerant schemes for the mobile agent environment. Our evaluation focuses on the checkpointing schemes and deals with the cooperating agents. We examine fault tolerance with regard to properties and requirements of mobile agents We derive the FANTOMAS (Fault-Tolerant approach for Mobile Agents) design which offers a user transparent fault tolerance that can be activated on request, according to the needs of the task. A theoretical analysis examines the advantages and drawbacks of FANTOMAS. The use of mobile agent, however, is critical and requires reliability in regard to mobile agent failures that may lead to bad response time and hence the availability of the system may lost. In this paper, a fault tolerance technology is proposed i!
n order that the system autonomously detect and recover the fault of the mobile agent due to a failure in a transmis¬sion link.

Abstract: Due to their unique properties and behavior, the Shape Memory Alloys (SMAs) play an increasingly important role in the intelligent systems performance. Recent applications in structural actuation and sensing demand increased material capabilities. This paper reviews the main advantages and the properties of SMAs and presents the design strategy for a typical shape memory actuator configuration of intelligent systems, using as active element Ni-Ti SMA spring working against a conventional steel spring. It also includes the thermal analysis experiments, in order to determine the transformation temperatures for the studied SMA spring. For design optimization a comprehensive graphical interface (based on the thermal analysis results), which runs under Visual Basic, has been developed for this application. It provides a user friendly environment allowing intelligent system parameters configuration as well as choosing the most adapted analysis methods and data displayi!

Abstract: this paper presents a dual simulation environment for simulating different type of telecommunication networks integrating intelligent agents. Agents are considered as advanced tools for resolving complex issues in networking based on intelligent and dynamic features. To test the efficiency of these proposals, new simulation environments, integrating both agents and network components, are required. In this paper we propose an extension with intelligent capabilities to a networking platform. This dual simulation environment has been tested for implementing agents in a DiffServ network to improve its performance. Simulation results show the efficiency of integrating agents within telecommunication networks and also prove that such a dual simulation environment is needed to test new techniques based on agents and multi-agent systems in networking.

Abstract: Creep stresses and strain rates for a transversely isotropic and isotropic materials have been obtained for a thin rotating disc using Seth's transition theory. Results obtained have been discussed numerically and depicted graphically. It is seen that a disc made of transversely isotropic material rotating with higher angular speed increases the possibility of fracture at the bore as compared to a disc made of isotropic material and possibility of fracture further decreases with the increase in measure N. The deformation is significant for transversely isotropic disc for the measure N =7.

Title of the Paper: A New Method Based on Extension Theory for Partial Discharge Pattern Recognition

Email addresses of all the authors: cyl@cycu.edu.tw,hcchen@ncut.edu.tw

Abstract: This paper proposes a new partial discharge (PD) pattern recognition method base on the extension theory. First, five types of defect models are well-designed on the base of investigation of many power equipment failures. A commercial PD detector is used to measure the three-dimension (3D) PD patterns, then two fractal features (fractal dimension and lacunarity) and mean discharges of phase windows are extracted from the raw 3D PD patterns. Second, the matter-element models of the PD defect types are built according to the PD features derived from practical experimental results. The PD defect type can be directly identified by correlation degrees between the tested pattern and the matter-element models. To demonstrate the effectiveness of the proposed method, comparative studies using a multilayer neural network (MNN) are conducted on 200 sets of field-test PD patterns with rather encouraging results.

Abstract: The purpose of this work is analysis of computational language concepts and introduction of novel pertinent ones in order to provide a new computational metamodel of interaction signatures in UML4ODP FDIS. we mainly introduce the concept of Functional computational interface which unify signal and operation interfaces notions. The unification of signal and operation interactions concepts is presented by introducing the Parameterized interaction concept. We show that parameterized interactions are of two main kinds; namely, primitives and compounds. we also introduce the notion of incoming and outgoing primitives. As an application of our modeling choices we redefine interaction, refinement and type checking rules in a concise manner, and then specify them using the useful specification functionalities of OCL 2.0, showing how novel definitions as well as their specification are easy to read, write and understand.

Title of the Paper: Structural properties of linear generalized systems
Authors as they appear in the Paper: Valeriu Prepelita
Email addresses of all the authors: valeriuprepelita@yahoo.com
Number of paper pages: 11
Abstract: Generalized linear systems are considered, which contain in their state-space representation matrices with elements functions of bounded variation and controls in the space of regulated functions. The Perron-Stieltjes integral is used to obtain a variation-of-parameters formula. On this basis the formula of the state of the system as well as the input-output map are derived. The fundamental concepts of controllability and reachability are analysed in this approach by means of two controllability and reachability Gramians. An optimal control is provided which solves the problem of the minimum energy transfer. The observability of these generalized systems is studied. In the case of completely observable systems a formula is obtained which recovers the initial state from the exterior data. The duality between the concepts of controllability and observability is emphasized as well as Kalman's canonical form.

Abstract: A multichannel recording system of extracellular cortex is utilized to acquire the neural signal of primary somatosensory cortex in rats. The extracellular neural recording system includes mainly the acquisition sub-system, the monitoring sub-system and the analyzing sub-system. We use the microwire array electrode to record different signal of three types; those are from on air, from S1HL without stimulation and from S1HL with stimulation by scratching the claw of the left hind leg using a brush. A signal processing system is applied to deal with the saved data. Through the method of spectral subtraction, we can reduce the influence of noise. Beside, nonlinear energy operator algorithm is employed to detect the timestamp of evoked potential by external stimuli. The signals are according to the time interval between preceding and following of timestamp to separate apart into every section. Each section can proceed to extract the features from every small segment of!
the signals and classify evoked potential segments that own similar features to the same group in the future. Finally, the information of the monitor system are apply to verify the accuracy of spike detection that the information comprises the action of external stimulus, the waveform of neural signal and the voice of speaker, simultaneously. Through the result of experiments, the developed recording system is suitable for intracortical signals recording; the proposed method is feasible and effective for noise reduction and spike detection of extracellular evoked potentials.
