In recent year’s fractional kinetic equation are studied due to their usefulness and importance in mathematical physics, especially in astrophysical problems. In Astrophysics kinetic equations designate a system of differential equations, describing the rate of change of chemical composition of a star for each species in terms of the reaction rates for destruction and production of that species. Methods for modeling processes of destruction and production of stars have been developed for bio-chemical reactions and their unstable equilibrium states and for chemical reaction networks with unstable states, oscillations and hysteresis. The aim of present paper is to find the solution of generalized fractional order kinetic equation, using a new special function. The results obtained here is moderately universal in nature. Special cases, relating to the Mittag-Leffler function is also considered. © Springer International Publishing Switzerland 2016. Source

Advanced Encryption Standard, a federal information processing standard is an approved cryptographic algorithm that can be used to protect electronic data. The AES can be programmed in software or built with pure hardware. However field programmable gate array offers a quicker and more customizable solution. This paper presents the AES algorithm with regard to FPGA and the very high speed integrated circuit hardware description language. Modelsim SE PLUS 5.7g soft ware is used for simulation and optimization of the synthesizable VHDl code. Synthesizing and implementation of the code carried out on Xilinx -project navigator, ISE 8.2i suite. All the transformations of both encryption and decryption are simulated using an iterative design approach in order to minimize consumption. This paper talks of AES 128 bit block and 128 bit cipher key and is implemented on Spartan 3 FPGA. © 2010 IEEE. Source

We have performed the first-principle study to analyze the structural and electronic properties of aluminum arsenide under the application of pressure. The computations have been carried out using the ground state total energy calculation approach of the system. The first-principle approach has been used to compute the stability of various phases of AlAs, like original zinc blende (B3), intermediate NiAs (B8), NaCl (B1) and CsCl (B2) type as a function of pressure. The study observes a B3-B8, B3-B1 and B3-B2 transitions at 6.99 GPa, 8.18 GPa and 73.43 GPa. The computed phase transition pressures, lattice parameters, bulk modulus, and energy gaps are in good agreement with their experimental as well as theoretical counterparts. Band structure and density of states analysis have also been performed and results have been discussed in detail. © 2010 Elsevier B.V. All rights reserved. Source

This paper presents the design and analysis of Microstrip Band pass Filter at 8 GHz. An artificial neural network model to determine the Magnitude and Phase variations of scattering parameters (S-parameters) of these filters is also proposed for various frequencies. Performance of the proposed model is evaluated in terms of average and maximum estimated errors. Comparison of the EM simulated Results with neural models is also presented. © 2010 IEEE. Source

An algorithm for order reduction of linear multivariable systems has been presented using the combined advantages of the dominant pole retention method and the error minimization by particle swarm optimization technique. The denominator of the reduced order transfer function matrix is obtained by retaining the dominant poles of the original system while the numerator terms of the lower order transfer matrix are determined by minimizing the integral square error in between the transient responses of original and reduced order models using particle swarm optimization technique. The reduction procedure is simple and computer oriented.The proposed algorithm has been applied successfully to the transfer function matrix of a 10 th order two-input two-output linear time invariant model of a practical power system. The performance of the algorithm is tested by comparing the relevant computer simulation results. © 2010 Springer-Verlag Berlin Heidelberg. Source
