Abstract: RFID is a wireless communication technology that provides automatic identification or tracking and data collection from any tagged object. Due to the shared communication channel between the reader and the tags during the identification process in RFID systems, many tags may communicate with the reader at the same time, which causes collisions. The problem of tag collision has to be addressed to have fast multiple tag identification process. There are two main approaches to the tag collision problem: ALOHA based algorithms and tree based algorithms. Although these methods reduce the collision and solve the problem to some extent, they are not fast and efficient enough in real applications. A new trend emerged recently which takes the advantages of both ALOHA and tree based approaches. This paper describes the process and performance of the tag anti-collision algorithms of the tree-ALOHA trend.

Title of the Paper: MATHEMATICAL MODEL OF RESISTOR EFFECT ON THE SYNCHRONIZATION SYSTEMS

Number of paper pages: 10
Abstract: A new mathematical model –built using the synchronous drive system with electrical shaft was introduced and the effect of the additional resistor on the synchronous capability and recovery time of the system was studied and its optimal value – to be added to the common rotor circuit of the system -was determined. The results show that the relationship between the additional resistor and the system's synchronous capability depends on the difference of loads. It was found that increasing the additional resistor value - with increasing the load difference - results in better synchronous capability and recovery time. However, the system efficiency decreases. To overcome this main drawback, a controller block was added to the model to determine the optimal value of the additional resistor according to the difference of loads on the motors' shafts. The suggested model was verified experimentally using a crane system consisting of two identical induction motors, where th!
e system load (total load) is distributed on two motors depending on the load position. It was found that the experimental results closely match the results obtained using the proposed mathematical model The synchronous capability and recovery time for the synchronization process of the system will be faster in implementation than the calculated values because of the presence of the gear box were the speeds are reduced to the tenth of its maximum speed

Title of the Paper: Decision Processes in Public Organizations

Number of paper pages: 10
Abstract: Application of binary Analytic Hierarchy Process in a decision process related to public sector is in the main focus of this work. We argue that the standard nine point scale based rating system used by the classical Analytic Hierarchy Process is not the most optimal one with respect to decision processes in the majority of public organizations. This mainly because it requires a lot of resources that such organizations do not have. Therefore a simpler rating system like binary or ternary point scale can be used instead. At the same time simpler rating systems are not very effective when a large number of criteria is involved since pairwise comparisons with respect to different criteria might end up with the same evaluation due to lack of alternatives.

Title of the Paper: On the temporal evolution of the vertical momentum fluxes within the Marine Atmospheric Boundary Layer
Authors as they appear in the Paper: Costas Helmis
Email addresses of all the authors: chelmis@phys.uoa.gr
Number of paper pages: 10
Abstract: In the frame of the CBLAST-Low project, the vertical structure of the Marine Atmospheric Boundary Layer (MABL) was studied using remote and in situ sensing instrumentation at the southern coast of the Nantucket Island, MA, USA, during 2003. Since a Low-Level Jet (LLJ) was frequently observed at low heights, it is of interest to examine the modification of the vertical transport of momentum fluxes and the possible influence on the vertical structure of the Turbulent Kinetic Energy (TKE). Thus two cases of a LLJ development (the 3rd and the 7th of August 2003) were examined, regarding the momentum transport and the standard deviation of the vertical component of the wind profiles which is related with the TKE. According to this study an intense modification of the vertical profiles of momentum fluxes and TKE was evident mainly above the LLJ core, following the temporal evolution of the developed LLJ. This fact modifies the vertical turbulent structure of the marine A!
tmospheric Boundary Layer as well as the expected levels of TKE values

Abstract: A new method to get features for rigid registration is presented in this paper. Attribute scale spaces are constructed by attribute operators. The attribute thresholds and gray thresholds are obtained by the level set histogram automatically. The contour can be extracted in high scale image. The highest scale images are very similar. This method turns the multi-model registration into the mono-model. Some important properties of the method are proposed and proved. The simple similarity measurement and the global searching optimum algorithm is applied to match based on edge features extracted by our method. The new method has strong anti-noise and the edge of object keeps good. The experiment results show that using these features extracted by our method help to improve the aligning precision and the computing time.

Abstract: In this paper the efficiency and linearity behavior of three-way Doherty amplifier is analyzed. The amplifier is designed in the configuration with two quarter-wave impedance transformers in the output combining circuit with LDMOSFETs in carrier and peaking amplifiers. The signals for linearization (the fundamental signals' second harmonics-IM2 and fourth-order nonlinear signals-IM4 at frequencies that are close to the second harmonics) are extracted at the output of peaking cells biased at various points. The Doherty amplifier is designed with the frequency diplexer at the outputs of the Doherty cells that separates the fundamental signals and signals for linearization. The diplexer includes harmonic control circuit (HCC) which in combination with matching circuits, provides an optimal impedance for an adequate power level of signals for linearization, and either open circuit for the third harmonics (HCC class-3F) or short circuit for the third harmonics (HCC clas!
s-3IF). The linearization technique results in the suppression of the third- and fifth-order intermodulation products of Doherty amplifier.

Title of the Paper: A Robust Hybrid Technique for Signature Verification using Intelligent Encoding of Spatiotemporal Data

Email addresses of all the authors: zaher_ashraf@yahoo.com
Number of paper pages: 25
Abstract: This paper combines both offline and online signal processing techniques to construct a hybrid signature verification system that has a robust performance. The proposed system is real-time and is aimed at verifying handwritten signatures collected using a digitizing tablet. Consistency checking is performed prior to allowing signatures to be enrolled in the database via collecting 10 signatures from each signer and measuring the deviation in both the total signing time and the binary pattern of the pen movements from the average of the best six signatures. The system has a flexible architecture that can be easily modified to accommodate different degrees of security and consists of three consecutive phases. The first (introductory) phase is an online approach that is quite similar to the enrollment phase and represents an initial bottle neck for the verification process so that simple forgeries are quickly filtered out. The second (main) phase uses a combination of!
neural networks and linear predictive coding to construct a majority voting committee in a pattern recognition context to decide on the authenticity of the signatures that passed the first phase of the verification process. The third (optional) phase of the system encapsulates real-time data features into a set of stationary image frames suitable for offline processing. This phase is only required if the second phase fails to give a conclusive verdict whether a questionable signature is authentic or forged. A total of eight features were used in the implementation of the system that can be easily constructed using commercially-available software and hardware resources. The results proved to be promising achieving a 2.9% for the false acceptance rate and 8.8% for the false rejection rate. The paper concludes with a detailed discussion regarding the advantages and limitations of the proposed system and suggests feasible improvements as well as future extensions.

Abstract: The Lattice Boltzmann Method is applied to incompressible, steady, laminar flows at high Reynolds numbers varying in a range form 50 to 2000. The developing channel flow and the lid driven cavity flow are analyzed. The effect of the model Mach number on accuracy is investigated by performing computations at different Mach numbers in the range 0.1 - 0.4 and comparing the results with finite-volume predictions of the incompressible Navier-Stokes equations. It is observed that the Mach number does not effect the results within this range, and the results agree perfectly well with the finite-volume solution of the incompressible Navier-Stokes equations. An important purpose of the study has been to explore the stability limits of the method. It is observed that the maximum allowed collision frequency decreases with increasing Reynolds and Mach numbers, and this dependency is more predominant, and the limiting collision frequencies are lower for the channel flow compare!
d to the lid driven cavity flow.

Abstract: It is well known that the world of art (paintings, sculptures, graphics etc) is plagued by the virus of counterfeits and this issue is particularly sensible in a country like Italy where art has flourished for centuries and where in the XX century too many pieces of art of great painters were copied and/or counterfeited and sold for authentic. Counterfeiting is a crime which involve great amounts of money and is perpetrated at all levels, with no exclusion of the greatest art dealers. Once a style or painter has had success it is even too simple to find a epigone which either can copy a single painting or paints according to one particular style. Great examples in Italy are Morandi, De Chirico, Vedova etc. artists with a well defined (and therefore easy to copy) style. In our university we have developed and implemented a digital system which can prove without any doubt the authenticity of a piece of art and which is tamper-proof at all levels.

Abstract: Site characterization on geologic and soil conditions was performed for evaluating the site effects relating to the site-specific seismic response characteristics at a small urbanized area, Hongseong, in Korea, where structural damages were recorded by an earthquake of magnitude 5.0 on October 7, 1978. In the field, various geotechnical site investigations composed of borehole drillings and seismic tests for determining shear wave velocity (VS) profile were carried out at 16 sites. Based on the geotechnical data from site investigation and additional collection in and near Hongseong, an expert information system on geotechnical information was implemented with the spatial framework of GIS for regional geotechnical characterization across the entire study area. For practical application of the GIS-based geotechnical information system to estimate the site effects causing seismic hazards for the Hongseong area, spatial seismic zoning maps on geotechnical parameters, !
such as the bedrock depth and the site period, were created at the area of interest. Furthermore, seismic zonation of site classification according to the mean VS to a depth of 30 m from ground surface was also performed for seismic design at any location in the area of interest. From the spatial geotechnical information and seismic zonations, the capability of seismic amplification was examined at plain and hill locations in Hongseong.

Abstract: - lIn this paper an analytical solution is offered to solve the basic fixed head hydrothermal scheduling problem. By applying Kuhn tucker the equations for optimality is derived. It is proved that the ratio of incremental costs between any two schedules is constant for each hydro plant by manipulating the equations. In terms of the reference hydro plants incremental cost the hydrothermal scheduling problem can be decomposed as set of single variable quadratic functions. By solving the quadratic equation the allocation of all hydro plants for all schedules can be determined .The thermal plants have be scheduled for the remaining demand. This method is applied to a case study and the results prove the effectiveness of the method.
Keywords: : Hydrothermal scheduling, Kuhn tucker conditions, incremental cost, transmission loss, valve point loading.

Title of the Paper: Analysis of the Thermal Damage on Homogenized Multi-Materials under Thermo-Mechanical Behavior

Abstract: In the recent high technologies, the increasing need of structures having multiple functions orientates designers to combine materials in order to obtain, according to coupling scales, multi-materials structures. These structures, while functioning, are subject to variable thermal load, leading to a damage that can be fatal in some applications. So, the study of the behavior of these structures, while they are under thermal cycling solicitations, seems to be very important in order to be able to predict their lifetime and their response to any applied solicitation. It is obvious that the variation of the nature of thermal and mechanical solicitation in term of amplitude and frequency leads to a variation of the resulting damage. But at the level of our knowledge, this effect is not studied before in the literature on multi-materials. In this work, we propose a numerical analysis of the thermo-elasto-plastic behavior of these multi-materials and their damage under t!
hermal cyclic solicitations, while using the homogenization technique. This study is done in two dimensions on a cylindrical multi-material constituted of two layers, subjected to a periodic heat flux applied in the inner face of this cylinder and an exchange condition on the opposite face. The other faces are supposed isolated. The sample is supposed fixed at the isolated faces and free in the radial direction. The damage model is based on the works of Lemaitre and Chaboche [6]. This damage model is not done for multi-materials; it is applicable only to one material apart. So the homogenization of these multi-materials permits us to study the damage of the multi-layers as it is a unique material. The numerical results are presented for different forms and frequency of heat flux cycling (triangular, square and sinusoidal wave excitations) and for different thicknesses of the multi-material. Finally we do a comparison of the multi-material damage with respect to different he!
at flux excitations

Abstract: New families of computation-efficient parallel prefix algorithms for message-passing multicomputers are presented. The first family improves the communication time of a previous family of parallel prefix algorithms; both use only half-duplex communications. Two other families adopt collective communication operations to reduce the communication times of the former two, respectively. The precondition of the presented algorithms is also given. These families each provide the flexibility of either fewer computation time steps or fewer communication time steps to achieve the minimal running time depending on the ratio of the time required by a communication step to the time required by a computation step. Relative merits and drawbacks of parallel prefix algorithms are described and illustrated to provide insights into when and why the presented algorithms can be best used.

Abstract: The aim of this research is to carry out appropriate method to detect Temporary Change in ARMA (1, 1) data. Estimation of model parameters and outlier effects are used to iteratively for joint estimation procedure. The data simulation is generated from ARMA (1,1) model using 4 parameters combination of AR and MA. Four different approaches of variance calculation are used to detect presence of outlier, i.e. Ordinary Least Square (LS) using Omit-one data, LS with replacing data by fit, Median Absolute Deviation (MAD) using Omit-one data and MAD with replacing data by fit. The result shows Omit-one approach can detect outlier better than Fit approach for all cases. Furthermore MAD-Omit-one is slightly better than LS-Omit-one. The result above is implemented to Surabaya's Air Pollutant data get same result, MAD-Omit one is slightly more powerful to detect outlier. Conclusion of this research is Joint Estimation method using MAD-Omit-one as approach of variance calcula!
tion give better result than three other approaches.

Abstract: A major advantage of e-Learning technology is to enable learners to learn in any place, so visually impaired people should benefit from the technology and perform their learning activities without making difficult journey to schools. However, it is usually inconvenient for the visually impaired people to participate in digital learning because the design of e-Learning web sites seldom considers their requirements. In the near future, their needs would probably continue to be neglected because the cost of redesigning web sites could not be justified. Therefore, we propose to approach this problem by converting original web pages to an audible form. Our research makes use of an open source e-Learning platform that conforms to the SCORM 2004 standard. By integrating the speech synthesis system developed by another academic institute and the screen reader, our prototype can explain audibly the logical structure of a Web page produced by JSP, and the navigational links !
and buttons to the visually impaired without changing the original design of a e-Learning site. An evaluation of the prototype shows that this design can help visually impaired users to comprehend the structure of an e-Learning unit, and we hope that it will improve their willingness as well as ability to visit and utilize e-Learning web sites.

Abstract: A novel voice activity detection (VAD) algorithm using auto-correlation function with sub-band weighting in the feature combination is proposed. To exploit the inherent characteristic of periodicity of speech signal, in this letter the well-known "Auto-Correlation Function (ACF)" is defined in the wavelet packet domain to evaluate the periodic intensity of each sub-band, which instead of periodic intensity of full-band system. Due to that the noise corruption on each sub-band is different from each other, the multiple features recombination is utilized in the proposed VAD system. In this letter, the signal to noise ratio (SNR) is employed to weight utility rate of each frequency sub-band. Experimental results show that the combined feature parameter can extract the speech activity under poor SNR conditions, and it is also insensitive to variable-level of noise.

Abstract: Impact echo method is an effective way to assess flaw in concrete. The commercially available impact echo analysis is interpreted manually, thus, to evaluate large area by the method is neither practical nor cost effective. In order to enhance the method in application to plate structure such as bridge decks, where duration of investigation plays substantial influence on traffic activity, data analysis and interpretation should not only be rapid and objective but also provide automatic mapping of deck quality at the end of investigation. This paper represents the development of algorithm for automatic impact echo data analysis in frequency domain and verification of the proposed method through theoretical and experimental effort. The algorithm has been developed based on the peak frequency movement from thickness frequency (fT) of slab in conjunction to an allowable range at which migration of thickness frequency is allowed in evaluating the investigated portion wi!
thout any defect. In addition, automatic identification of flaw in plate structure in term of flaw location is presented. For the verification of developed algorithm, an experimental program is conducted in laboratory with controlled flaw specimens and varying flaw sizes. It is observed that the algorithm responses well with flaw location being irrespective to the studied flaw sizes. As a result, a software program can be developed based on this algorithm to eliminate the presence of skilled attendance during field investigation of slabs.

Abstract: Software testing provides a means to reduce errors, cut maintenance and overall software costs. Early in the history of software development, testing was confined to testing the finished code, but, testing is more of a quality control mechanism. However, as the practice of software development has evolved, there has been increasing interest in expanding the role of testing upwards in the SDLC stages, embedding testing throughout the systems development process. Numerous software development and testing methodologies, tools, and techniques have emerged over the last few decades promising to enhance software quality. While it can be argued that there has been some improvement it is apparent that many of the techniques and tools are isolated to a specific lifecycle phase or functional area. This paper presents a set of best practice models and techniques integrated in optimized and quantitatively managed software testing process (OptimalSQM), expanding testing through!
out the SDLC. Further, we explained how can Quantitative Defect Management (QDM) Model be enhanced to be practically useful for determining which activities need to be addressed to improve the degree of early and cost-effective software fault detection with assured confidence, then optimality and stability criteria of very complex STP dynamics problem control is proposed.

Abstract: Using a 2D decision support system based on a recent analytical model, this paper is the first to demonstrate that bridge specific characteristics require a detailed analysis to determine the collapse load. A parameterized study of the limit load capacity is necessary to calculate the worst case positioning of any kind of load. Because of the complexity of finite element modeling and the computation time requirements of 3D finite elements models for a large number of load positions, it is regularly assumed that collapse positions are situated at the crown of the arc. Empirical testing in this paper clearly demonstrates that this is not the case. The here developed approach allows for a quick scan of any type of masonry arch bridge, thus providing the necessary information on the critical range of load positions to be analyzed in more detail by a 3D modeling approach.

Abstract: Heat exchangers that transfer energy from flue gas to steam are important units of thermal power stations. Their inertias are often decisive for the design of the steam temperature control system. In this paper, the analysis and the simulation of the dynamics of the steam superheater are discussed. Superheater is simulated as a unit of a control loop that generates steam of desired state values. To simulate the steam superheater on the computer, the exchanger is described by the set of partial differential equations. The equations are then solved numerically by modified finite difference method. Discussion of method and qualitative and quantitative results are presented. Paper describes use of Simulink S-functions which make it possible to set-up the most complex systems with complicated dynamics. There's a comparison of M and C S-functions, which are two main approaches when building user-defined blocks in Simulink, regarding both the performance and the efficienc!
y of the simulation for M and C versions of the codes and the possibility to perform a real-time simulation.

Abstract: Wireless Sensor Networks (WSN) are vulnerable to a wide set of attacks which threaten the network operation. Although communication and security technologies for computer networks have reached a mature stage, their applicability in WSNs is disputable due to their infrastructure-less operation and the limited node and network resources. Focusing on the routing procedure, this relies in the cooperation among neighboring nodes and a long list of attacks that can cause serious damage have already been identified. The situation is futher aggravated as the next generation wireless sensor network will be larger and larger. To face this problem, we propose a secure routing protocol (Ambient Trust Sensor Routing, ATSR) which adopts the geographical routing principle to cope with the network dimensions and part of the routing attacks, while it relies on a distributed trust model for the detection of another part of the routing attacks. Both direct and indirect trust informat!
ion is taken into account to evaluate the trustworthiness of each neighbour. An important feature of the proposed routing solution is that it takes into account the remaining energy of each neighbour, thus allowing for better load balancing and network lifetime extension. Based on computer simulation results we evaluate the additional energy consumption caused by the exchange of indirect trust information and the benefits stemming from the adoption of our algorithm.

Abstract: The main objective of the present paper is to estimate the electric power distribution of a wind farm using the output power distribution and the probability of simultaneously running of wind turbines. In this paper, a methodology for the electric power distribution of a wind turbine, using the characteristic output power â€"wind and the Weibull distribution of wind speed was given first. The methodology was applied to a region from north-east of Romania, and, finally, the analytic distributions were compared to Monte-Carlo simulation.
Keywords: Wind energy, wind speed, Weibull distribution, output power distribution, LOLP, EIR.

Abstract: Heat exchangers that transfer energy from flue gas to steam are important units of thermal power stations. Their inertias are often decisive for the design of the steam temperature control system. In this paper, the analysis and the simulation of the dynamics of the steam superheater are discussed. Superheater is simulated as a unit of a control loop that generates steam of desired state values. To simulate the steam superheater on the computer, the exchanger is described by the set of partial differential equations. The equations are then solved numerically by modified finite difference method. Discussion of method and qualitative and quantitative results are presented. Paper describes use of Simulink S-functions which make it possible to set-up the most complex systems with complicated dynamics. There's a comparison of M and C S-functions, which are two main approaches when building user-defined blocks in Simulink, regarding both the performance and the efficienc!
y of the simulation for M and C versions of the codes and the possibility to perform a real-time simulation.

Abstract: The operation of vertical transport installations are based on cable systems with electrical adjustable operation, which ensures the technical conditions regarding time variation in speed, the current in the main actuation engines and the acceleration during start-up and breaking. The actuation electrical systems are part of the category of the fast process of the automation equipment. For the vertical transport installation the size which has to be controlled from a command is the speed, the dependent factor being the tahogram. Adjusting determines the dependence of the sizes in the process, through a default law, both in relation to the independent sizes and in relation to the dependent ones from the process, assuring the reduction of the influence of harmful sizes to the process. The stability of an automatic system can be defined in different ways. We will consider stability of an automatic system, that feature which is that when it is subjected to the action o!
f one harmful size of the moment the system will return in the end at the stationary phase. Thus, the Balance Survey also deals with the determination of variation functions in time of the current of the main actuation motor, of speed (main electrical actuation motor rpm) when starting the vertical transport installation, as well as the study in time of the variation of speed when applying loading shock.

Abstract: In recent years the increasing of open source solutions extended the business opportunities for the IT companies but at the same time created problems for the choice and evaluation processes. For these reasons the need of approaches and tools to address this issue has become capital. We present FAME (Filter, Analyze, Measure and Evaluate), an iterative approach for Open Source software assessment, and FAMEtool, a support tool for this methodology. In this paper we analyze the most interesting and important assessment methodologies and the FAME approach has been derived by these, more heavyweight, proven approaches developed in a University research and consulting company environment, to match the needs of small organizations. The proposed approach has been used by FlossLab, the first spin off of University of Cagliari, to select the best solutions. The FAME tool, developed to make easier the whole process, supports the users in this choice by an interactive approac!
h, particularly in the filtering and analysis phases.

Abstract: In this paper, the interval-valued intuitionistic fuzzification of the notion of a bi-ideal in ordered semigroups is considered. Using a collection of bi-ideals with additional conditions, an interval-valued intuitionistic fuzzy bi-ideal is constructed. Natural equivalence relations on the set of all interval-valued intuitionistic fuzzy bi-ideals of an ordered semigroup are investigated. In terms of interval-valued intuitionistic fuzzy subset, conditions for an ordered semigroup to be left (right) regular, completely regular and regular ordered semigroups are provided. Characterizations of interval-valued intuitionistic fuzzy bi-ideals in ordered semigroups are given.
Keywords: Ordered semigroup, regular ordered semigroup, completely regular ordered semigroup, bi-ideals, interval-valued intuitionistic fuzzy subsets; interval-valued intuitionistic fuzzy bi-ideals.

Abstract: In this paper, we introduce a DCT based steganographic method for gray scale images. The embedding approach is designed to reach efficient tradeoff among the three conflicting goals; maximizing the amount of hidden message, minimizing distortion between the cover image and stego-image, and maximizing the robustness of embedding. The main idea of the method is to create a safe embedding area in the middle and high frequency region of the DCT domain using a magnitude modulation technique. The magnitude modulation is applied using uniform quantization with magnitude Adder/Subtractor modules. The conducted test results indicated that the proposed method satisfy high capacity, high preservation of perceptual and statistical properties of the stego-image and also it is robust, to some extents against several levels of JPEG compression.

Abstract: Abstract: - In the last years, the traditional tools used by visually impaired to navigate in real outdoor environments (white cane and guiding dogs) are to be substituted with electronic travel aids (ETA). These devices are capable to improve the mobility of blind users in unknown or dynamically changing environment, but up to date no ETAs have been practically implemented. In this paper, the most important theoretical and practical results obtained in the field of ETAs are presented first. Some original results of the author's team, including new concepts in this field, like integrated environment for assisted movement, acoustical virtual reality (AVR), bioinspired solutions are then discussed in more detail. Conclusions and the further developments in this area are also presented.

Abstract: Modeling the complex state of stock markets to maximize satisfaction of stock traders has always been a significant concern of scholars. However, still this field suggests the need for more accurate and comprehensive models. Development of these models is difficult because of the unpredictable economic, social and political variables that surely affect manners of stock markets. The portfolio model developers have escaped the inspired complexity by some simplifying assumptions that result in their less practicability. In this paper subsequent to an introduction to the field of portfolio optimization and literature review of the investment approach of Technical Analysis (TA), capabilities of TA in improving the level of portfolio models and its potentiality to address the main challenges of the field are discussed. The paper also proposes the modular structure in which TA would be helpful.

Abstract: Neural Networks are nowadays a promising technique in various financial applications. Numerous studies have demonstrated that the Neural Networks are accurate and efficient. Yet research for the field of forecasting government bond yield is short. Among these limited number of studies, Backpropagation network (BPN) seems to be the most used method. However, suffering form the potential problems, such as slow training speed, long processing time, and possible local minimum, BPN may not be the best solution for all applications in practice. The purpose of this research is to provide an in-depth study of effects of on the performance of different neural networks in Taiwan¡¦s 10-year government bond yields forecasting. Five selected models with different structures, namely Backpropagation network (BPN), Resilient Propagation (RPROP), Radial Basis Function Neural Network (RBFN), Adaptive Neuro-Fuzzy Inference Systems (ANFIS), and Support Vector Regression (SVR), are inv!
estigated and the results are analyzed and compared. The results indicate that (1) the number of nodes in the hidden layer is insensitive to the prediction. (2) The recommended number of input nodes is five. (3) More training samples do enhance forecasting performance in our study. (4) The performance of RBFN is the best, followed by ANFIS and RPROP, SVR, and then BPN. (5) BPN is efficient but not the best approach. (6) Our result reveals that RBFN is a useful predicting approach in government bond yield, it performs better than other four models. The recommended structure for RBFN in this application is five input nodes, six center nodes in the hidden layer, and one output node.
