An industrial buyer, who can reschedule its production plan, may develop strategic bid by shifting its demand from high price period to low price period. Based on this concept, a new optimization formulation has been proposed to develop bidding strategy of such buyers considering Price Responsive Demand Shifting (PRDS). Since the bidding strategy of the buyer depends upon the market clearing price, which is volatile/uncertain due to various factors like gaming behavior of participants, demand forecasting error, transmission congestion etc, the proposed optimization problem is formulated as a stochastic linear problem, comprising of two sub-problems. The first sub-problem represents the market clearing process by the System Operator, which is formulated to maximize the social welfare of the market participants, while the second sub-problem aims at maximizing the purchase cost saving of the industrial buyer. The optimal bidding strategy has been obtained by solving these two sub-problems considering hourly market clearing for 24-hour scheduling period. The effectiveness of the proposed method has been tested on a 5-bus system and modified IEEE 30-bus system. Results obtained with the demand shifting based bidding strategy have been compared with those obtained with a Conventional Price Quantity (CPQ) bid strategy. It has been observed that the proposed approach leads to enhancement in the purchase cost saving as compared to the CPQ and meets the energy consumption targets of the industrial buyer. © 2017 by De Gruyter 2017.

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.

As the technology increases day by day, human dependency increases on technologies. In present scenario everyone wants to do their work, business etc with the help of computer or with internet. Hence this increases the possibility of large-scale unauthorized copying which may lead to undermine the music, film, book and software industries. These concerns over protecting copyright have triggered significant research to find ways to hide copyright messages and serial number into digital media. An important sub discipline of information hiding is Watermarking. Digital Watermarking is an authentication technique which permanently embeds a digital signal (watermark) in text, image, audio, video files (any Data) by slightly modifying the data but in such a way that there are no harmful effects on the data. In this paper, we present audio watermarking technique that utilized the manipulation in high frequency of an audio signal to hide secret message The experimented result developed through MATLAB show that the usefulness of this technique. © 2011 Springer-Verlag Berlin Heidelberg.

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.

Zinc ferrite (ZnFe2O4) and Manganese ferrite (MnFe2O4) nanoparticles were synthesized by using Chemical co-precipitation method. The effect of annealing on the structure and magnetic properties has been investigated at different temperature. The structure and magnetic properties of these nanoparticles were characterized by using XRD, TEM and Vibrating sample magneto meter (VSM). The lattice constant of MnFe2O4 is significantly increases with further increasing annealing temperature. The average particle size were determined by using Transmission Electron Microscopy (TEM) which were in good agreement with results obtained by XRD. Magnetic properties were performed by using VSM technique which shows that after annealing the behavior of these nanoparticles change from super paramagnetic to ferromagnetic. © 2015 American Scientific Publishers.

Image denoising is the manipulation of the image data to produce a visually high quality image. There are different types of filters like mean filter, median filter, bilateral filter, wiener filter etc. To remove a single type of noise such as salt and pepper noise, speckle noise, Gaussian noise etc. But if the image is corrupted by mixed noise then these filters do not remove the noise exactly. Here a white flower image has been taken for denoising purpose. The white flower image is corrupted by mixed noise at zero mean and different variances to produce different noisy images at zero mean and respective variances. © 2015 IEEE.

Cognitive radio is an evolving technology which is able to solve the problem of spectrum inefficiency. Every wireless system occupies some bandwidth but there is limited spectrum which is allotted to the licensed user. This allotted spectrum is sometimes underutilized. Cognitive radio senses the spectrum, find the available space in the spectrum and allot it to the unlicensed secondary user without any interference to the primary licensed users. These unlicensed secondary users are called the cognitive radio users. Spectrum sensing is the main key task of cognitive radio. There are different types of spectrum sensing techniques which are energy detection, matched filter detection and cyclostationary detection. In this paper we are designing a cognitive radio system which can analyze the energy of the spectrum. Using energy detection technique, we analyze the performance of our system on different fading channels like additive white Gaussian noise channel, Rayleigh fading channel and Nakagami fading channel. © 2015 IEEE.

In recent years group III nitrides have gained recognition as being the most important materials for optoelectronics and electronics applications. The zinc-blende modification of GaN and AlN is receiving much attention over their wurtzite structure. Our present work deals with the detailed ab initio calculations of group III nitrides and phosphides in the zinc-blende phase. The plane wave pseudopotential approach is used to study the different properties of the material based on the concept of density functional theory (DFT). The converged plane wave cut-off energy (E(cut)) is used to set the number of plane waves, which varies from material to material. The calculated energy bandgaps are based on our theoretical equilibrium lattice constants. Our reported energy bandgap for InN (0.86eV) is in good agreement with the recently reported experimental result (>0.7eV and<1.0eV).
