The problem of frequency offset is very serious in case of orthogonal frequency division multiplexing communication systems (OFDM). The reason is that the frequency offset disturbs the relation of orthogonality among the sub carriers and lead to an interference known as inter-carrier interference (ICI). This paper studies the existing inter-carrier interference self cancellation methods and proposes a new and effective method to suppress the effect of frequency offset on OFDM systems. The method comprises of two simple steps. The first step is carried out at the transmitter end where a data symbol and its conjugate are mapped onto four sub carriers. The second step is carried out at the receiver end where the received signals are linearly combined. The result is that the ICI existing among the sub carriers is sufficiently reduced. The proposed method is supported with mathematical work and the simulation is done on MATLAB which proves that our proposed method reduces the bit error rate (BER) to a greater extent and also carrier-to-interference ratio (CIR) is increased than the existing self cancellation schemes. © 2015 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).

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.

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.

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.

This paper deals with ECG signal analysis based on Artificial Neural Network and combined based (discrete wavelet transform and morphology) features. We proposed a technique to truthfully classify ECG signal data into two classes (abnormal and normal class) using various neural classifier. MIT-BIH arrhythmia database utilized and selected 45 files of one minute recording (25 files of normal class and 20 files of abnormal class) out of 48 files based on types of beat present in it. The total 64 features are separated in to two classes that is DWT (48) based features and morphological (16) feature of ECG signal which is set as an input to the classifier. Three neural network classifiers: Back Propagation Network (BPN), Feed Forward Network (FFN) and Multilayered Perceptron (MLP) are employed to classify the ECG signal. The classifier performance is measured in terms of Sensitivity (Se), Positive Predictivity (PP) and Specificity (SP). The system performance is achieved with 100% accuracy using MLP. © 2013 Elsevier Ltd. All rights reserved.

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.

The influence of a gap provided in integral inclined ribs on heat transfer and friction factor enhancement is investigated. Experiments are conducted to obtain heat transfer and friction factor characteristics in a square channel with two opposite in-line ribbed walls for Reynolds numbers from 5000 to 40000. The test section of square channel composed of integral inclined ribs with a gap and has a length-tohydraulic diameter ratio (L/D h) of 20. The rib pitch-to-height ratio (p/e) is 10, the rib height-to-hydraulic diameter ratio (e/D h) is 0.060 and rib attack angle (α) varies in the range of 300 to 900 (4 steps). The relative gap position (d/W) and relative gap width (g/e) is varied in the range of 1/5-2/3 (5 steps) and 0.5-2.0 (4 steps), respectively. The enhancement in heat transfer and friction factor of this roughened duct was compared with smooth duct and duct roughened with continuous inclined ribs (with no gap) under similar flow condition. Presence of inclined ribs with a gap yields about 4-fold enhancements in Nusselt number and about 8-fold increase in the friction factor compared with smooth duct and about 1.3 times and 1.4 times higher than the case of continuous ribs (without gaps) for the entire range of parameters investigated. Ribs with relative gap width of 1.0 at relative gap position of 1/3 and attack angle of 60° provides maximum heat transfer and friction factor enhancement. © 2014 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

The paper presents a new speech enhancement algorithm using feedback particle filter. The innovation error based feedback structure is the decisive factor for Feedback particle filter. The robustness is key feature, this variant is found to improve the performance of the system reducing MSE as compared to conventional particle filter at even lower no of particles, without much preprocessing or modeling, gain and innovation error depends on values of variance and means of particle hence dynamically generated. The feedback particle filter outperforms a conventional particle filter. © 2015 IEEE.
