In this paper, Improved Particle Swarm Optimization (IPSO) approach is used in feature selection process-Linear Discriminant Analysis (LDA). This evolutionary random search method enhanced the classification rate with less computational time. The effectiveness of the proposed IPSO-LDA method is verified by employed Indian Face Database (IFD) and compare the results with existing methods. © 2015 IEEE.

Solid state electronics is used to increase the energy efficiency of electrical load devices. The harmonic distortion of current is increasing with the enhanced use of nonlinear loads i.e. solid state devices. Examples of nonlinear loads are personal computer, laptop, laser printer, fax machine, television set (TV), fluorescent tube with electronic ballast, compact fluorescent lamp, battery charger, adjustable speed drives, uninterrupted power supply (UPS) and any other equipment powered by switched-mode power supply (SMPS) unit. These nonlinear loads draw more current than the fundamental current and cause overloading of the components of the distribution system. Transformers are major components of the distribution system and are mainly affected by this overloading. This leads to higher losses, reduces the strength of insulation and consequently leads to reduction of useful life of the transformer. Aging of transformer increases due to overheating caused by overloading. This paper presents the results of a case study of aging of transformer caused by harmonics due to non linear loads. Here two transformers of 500 kVA and 100 kVA are considered which supply a technical institution and residential campus respectively. The harmonic currents produced by these loads are captured in the laboratory and their effect on transformers is studied. An attempt has been made to calculate the energy loss due to harmonic distortion caused by these nonlinear loads. The rise in operating temperature due to harmonic current and hence life expectancy of the transformers are calculated. ©2010 IEEE.

Minor millets are important food crops of a large group of people in rural, tribal and hilly areas in India. Nine hybrid varieties of minor millets seeds viz., Ragi ((Eleusine coracana variety FM & HR), Kodo (Paspalum scrobiculactum variety 41,48 & 439), kutki (Panicum sumatrense variety 8 & LMCO-2), Sanwa (Echinochloa frumentacea variety VL-29 & VL-172) have been studied for their fatty acid composition by gas chromatography. The Kodo-48 has highest (86.5%) total saturated fatty acid content whereas variety kutki-8 has 79.1% total unsaturated fatty acid content with better storage quality. The Sanwa BMVL-29 has highest content (46.9%) of linoleic acid (PUFA).

The EEG signals are the prime sources to diagnose and manipulate Epilepsy, state of coma and numerous studies. The EEG signals in the active brains constitute various body activities controlled or out of human consciousness. There exist considerable researches that focus to minimize the artifact values in the EEG domain. This paper is the evaluation of detection methods to study their efficiency and constraints of experimental limitations. © 2015 SERSC.

The problem of n-queens (n = 8) is a classical search problem in the field of machine learning. Backtracking is frequently applied to solve such constraint based problems, but it often suffers from exponential growth of computing steps/time as n increases. This paper describes the Rakhya's Method, which is an alternative approach to the method of backtracking. It is capable of finding more than one solutions for all values of n>3 in very few steps. There is a significant reduction in the number of steps, for instance, it takes 1,749,317,724 steps to achieve the first solution of 30-queens problem by backtracking whereas RAKHYA's Method presents its first solution in 32 steps. © 2014 IEEE.
