Performance is an important non functional aspect to be considered for any software system. Software Performance Engineering (SPE) is an approach to predict the performance of a software system early in the life cycle. In this paper we present a neural network model for the performance prediction of Multi-Agent system at the early stages of development. We used Feed forward back propagation neural network model for the performance prediction. The results are validated and a case study of Multi-Agent System is presented.

Spectrum sensing is a critical component of the Cognitive Radio that detects the presence of primary user signal in a channel. In this paper energy detection technique based on Neyman-pearson criterion is used to detect the presence of deterministic primary user (PU) signals in the channel. We have considered three different kinds of modulated signal such as BPSK, QPSK, DVB-T (2K mode) under additive white Gaussian noise (AWGN) and Rayleigh fading channel environment as specified in IEEE 802.22 standard for validating the algorithm. The simulation result shows that the energy detector achieves the desired probability of detection (≥0.9) with probability of false alarm (≤0.1) at low signal to noise ratio (SNR) up to −8dB for QPSK and DVB-T modulated signal with sample size of 64. The algorithm is also implemented in Xilinx Virtex2pro XC2VP30 (FFG896-7) Field Programmable Gate Array (FPGA). Hardware in loop (HIL) technique is used for verifying the algorithm in FPGA. The implementation result reveals that the algorithm fits into the Virtex2pro FPGA and can execute with operating frequency between 110 to 138 MHz for different sample size of primary user signals.

This paper presents the stability analysis of a class of nonlinear time-varying delay systems with parameter uncertainty, through extended Takagi-Sugeno fuzzy modeling. The delay-dependent stability and robust stability criterions are presented using delay decomposition approach, in terms of linear matrix inequalities (LMIs). The time-varying delay is assumed to be bounded and continuous need not be differentiable. Simulation results are discussed to show the efficiency of the technique and compared the maximum allowable upper bound (MAUB) with literature.

Coverage analysis defines the tracing of a program by test cases. It also helps in the testing process by finding the areas of a program not exercised by a set of test cases. Introducing new test cases to increase coverage, and determine the quantitative measure of the code, which is an indirect measure of quality. Coverage analysis provides more benefit when applied to an application that makes a lot of decisions rather than data-centric applications, such as a database application. This paper will discuss the issues that make test case coverage analysis a complicated task and how those issues are being addressed. We will describe the technique for improving the maximum coverage for test case of a program by using a data mining technique called Association rule Mining.

In this paper we have proposed a new way to achieve the optimum learning rate that can reduce the learning time of the multi layer feed forward neural network. The effect of optimum numbers of inner iterations and numbers of hidden nodes on learning time and recognition rate has been shown. The Principal Component Analysis and Multilayer Feed Forward Neural Network are applied in face recognition system for feature extraction and recognition respectively. The paper shows that the recognition rate and training time are dependent on numbers on hidden nodes. In this approach we have used variable learning rate and demonstrated its superiority over constant learning rate. We have used ORL database for all the experiments.

In this paper, two dimensional Photonic Crystal square lattice circular ring resonator based Bandpass Filter (BPF) is designed by coupling in-line quasi waveguides and resonant cavity. The output efficiency of the circular ring resonator is investigated by varying size of the cavity. The normalized transmission spectra of circular Photonic Crystal Ring Resonator (PCRR) have been studied by using the Finite Difference Time Domain (FDTD) method. The Photonic Bandgap (PBG) has been calculated by Plane Wave Expansion (PWE) method. The simulation shows 100% transfer efficiency and 25 nm of bandwidth over the range of 1575 nm to 1600 nm. The impact of number of rings in the ring is also studied for determining the output efficiency and bandwidth.

An improved Clonal selection algorithm based Artificial Immune System (AIS) is given for solving Job Shop Scheduling Problem (JSSP). To reduce the optimal solution search space, a bio inspired positive selection principle is proposed to populate the initial antigen library. This proposed algorithm gives the better start up and faster converging towards the optimal solution for the given JSSP. The given algorithm has been simulated in Matlab tool and the results were compared with the Genetic Algorithm (GA) generated results for a well known bench marking problem. AIS produced optimal solution for more than 90% run which 15% produced by GA.

A recent trend in the research of ROM-less DDFS architecture, which is endowed with high speed, low power and high SFDR features and will generate the sine or cosine waveforms within a broad frequency range. In this work one high-speed, low-power, and low-latency pipelined ROM-less DDFS has been proposed and implemented in Xilinx Virtex-II Pro FPGA. The proposed ROM-less DDFS design has 32 bit phase input and 16 bit amplitude resolution with maximum amplitude error of 1.5×10−4. The FPGA implementation of the proposed design has an SFDR of −94.3 dBc and maximum operation frequency of 276 MHz by consuming only 22 K gate and 1.05 mW/MHz power. The high speed of operation and low power makes the propose design suitable for the use in communication transceiver for the up and down conversion.

Objectives of this paper are to simulate flow velocity patterns of cardiac valves in normal and abnormal conditions using electrical equivalent lumped parameter Cardiovascular System (CVS) model and validate with real subjects' echocardiograph. Our model consists of detailed representation of supine human CVS with baroreflex control. Cardic valves are characterized by resistance, inertance and bernoulli's resistance to exactly mimic the nonlinear, turbulent flow nature of physiological valves. Echocardiographs of real patients with valve abnormalities are collected. Echo derived indexes are implemented in model by tuning appropriate parameters based on sensitivity analysis. The simulated flow velocity patterns are well matching with Echo Cardiograph and also the model derived hemodynamic indexes have good agreement with real data. Therefore, our model has the ability to simulate more complicated hemodynamic principles in mitral stenosis and regurgitation of mitral, tricuspid, pulmonary and aortic valves.
