This paper is an attempt to provide a user friendly software package for steady state analysis of standalone SEIG. The steady state analysis is been carried out mainly with three modes in which generally a standalone SEIG is been operated. Three operating conditions of the generator are mathematically modeled and then simulated using conventional Matlabcommands. Active windows with these mathematical models are then created using Matlab's Graphical User Interface capability (GUI). The capacitance requirements of SEIG for its self excitation are also incorporated in this paper. © 2012 IEEE.

The wavelength assignment algorithm is a method to improve the performance in respect of blocking probability and to provide cost effective communication system. In this paper, we have developed a simple mathematical model which is used for the calculation of blocking probability of an OBS network. The implementation of the proposed model has less complexity and the computation used is quite efficient. This model can be implemented on different network topologies. The validity of model is supported by simulation results. © 2012 Elsevier GmbH. All rights reserved.

In this paper the design, implementation and performance analysis of four wave mixing (FWM) in optical communication system for different number of input channels is presented using various values of channel spacing. Here, all the input channels have been spaced evenly at various values like 6.25 GHz, 12.5 GHz, 25 GHz, 40 GHz, 50 GHz with the different number of channels at the input i.e. with 2, 4, 6, 8, 12 input channels. The simulation results reveal that the four wave mixing is minimum when the channel spacing is maximum i.e. 50 GHz with minimum number of channels i.e. 2 input channels. It is observed that on increasing the channel spacing, the interference between the input frequencies decreases and hence the four wave mixing also decreases. Also, on increasing the number of input channels/users, the interference between the input frequencies increases and thus, the four wave mixing also increases. © 2013 Elsevier GmbH.

In this paper, hum of a person is used to identify a speaker with the help of machine. In addition, novel temporal features (such as zero-crossing rate & short-time energy) and spectral features (such as spectral centroid & spectral flux) are proposed for person recognition task. Feature-level fusion of each of these features with state-of-the art spectral feature set, viz., Mel Frequency Cepstral Coefficients (MFCC) is found to give better recognition performance than MFCC alone. In addition, it is shown that the person identification rate is competitive over baseline MFCC. Furthermore, the reduction in equal error rate (EER) by 1.46 % is obtained when a feature-level fusion system is employed by combining evidences from MFCC, temporal and proposed spectral features. © 2012 Springer-Verlag.

This paper presents the mathematical models for wavelength routed WDM optical networks for optimization of blocking probability. This model works well for the networks with higher load. The proposed mathematical model is then compared with the earlier proposed mathematical model. Comparison proved that the model works better than the earlier proposed model. The value of blocking probability ranges from 0 to 10-4 in case of the proposed model whereas it lies in the range of 0-1 in earlier mathematical model. © 2012 Elsevier GmbH. All rights reserved.

This paper presents modeling and control of a hybrid Photovoltaic (PV), Diesel-Engine Generator (DEG) - Fuel Cell (FC) system connected to electric grid. A case study on impact of FC operation on the frequency stability of electric grid has been carried out. The model of fuel cell system includes a fuel cell generator, electrolyzer and a hydrogen storage facility. The limits on hydrogen volume due to limited storage capacity have also been incorporated. The modeling of photovoltaic is also presented and analyzed for a time period of 24-hours with varying solar radiation and temperature. Results of simulation indicate that FC system can contribute to frequency stability in both cases when the load increases and also when the load drops. This feature of FC system will be helpful if it is operated along with a hybrid Wind-PV System. © 2012 IEEE.

The Rapid developments in Internet Technologies and usage have made it easier to share and exchange personal or business information all over the world through web pages but majority of web pages on World Wide Web are equipped with illegal or harmful contents among which web pages with pornographic contents are accessed most frequently. For last two decades, computers and Internet are not beyond the reach of children. Effortless availability of pornographic contents is a growing problem that many guardians are concerned about. Even many companies are considering this issue seriously and taking careful measures to ensure that computing resources are properly utilized. This paper proposes a technique to detect the pornographic web pages using Support Vector Machine. © 2012 Springer India Pvt. Ltd.

Color is one of the most important low-level features used in image retrieval and most content-based image retrievals (CBIR) systems use color as an image features. However, image retrieval using only color features often provide very unsatisfactory results because in many cases, images with similar colors do not have similar content. As the solution of this problem this paper describes a novel algorithm for Content Based Image Retrieval (CBIR) based on Color Edge Detection and Discrete Wavelet Transform (DWT). This method is different from the existing histogram based methods. The proposed algorithm generates feature vectors that combines both color and edge features. This paper also uses wavelet transform to reduce the size of the feature vector and simultaneously preserving the content details. The robustness of the system is also tested against query image alterations such as geometric deformations and noise addition etc. Wang's image database is used for experimental analysis and results are shown in terms of precision and recall. © 2014 IEEE.

With the binary number system, the computation speed is limited by formation and propagation of carry especially as the number of bits increases. Using a quaternary Signed Digit number system one may perform carry free addition, borrow free subtraction and multiplication. However the QSD number system requires a different set of prime modulo based logic elements for each arithmetic operation. A carry free arithmetic operation can be achieved using a higher radix number system such as Quaternary Signed Digit (QSD). In QSD, each digit can be represented by a number from -3 to 3. Carry free addition and other operations on a large number of digits such as 64, 128, or more can be implemented with constant delay and less complexity. Design is simulated & synthesized using Modelsim6.0, Microwind and Leonardo Spectrum. © 2013 IEEE.

The performance of GMPLS network depends upon the various parameters such as number of channels, number of sources, traffic intensity etc. In this paper we have proposed a call blocking model for mode of operation to determine the type of applications suitable for GMPLS networks. Further we have suggested a switch model for GMPLS network and developed a mathematical model for GMPLS network for call blocking probability and call holding probability. In proposed model blocking probability of the network is reduced and then the call blocking performance of the model is compared with the call holding performance. © 2013 Elsevier GmbH.
