Present work deals with theoretical analysis of dispersion characteristics of long period fiber grating using straight forward coupled mode theory. Simple analytical solutions are obtained for co propagating core and cladding modes under linear regime. These solutions are used to derive expressions for transmission coefficient (tLPG), phase (φL), delay (τρ) and group velocity dispersion (Dρ) for proposed grating structure. Attention is paid to study the delay response of the grating, by varrying physical parameters like incident wavelength and coupling strength of grating. Negative values of group delay for certain value of coupling strength shows that long period fiber can be used as dispersion compansator device in optical fiber communication link. © Published under licence by IOP Publishing Ltd.

This paper shows a method for optimization of CHB inverter's harmonic performance under Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) control. The optimization techniques are used for solving the set of non-linear transcendental trigonometrical equations. SHE is implemented to reduce the THD value. The set of non-linear equation is minimized by Big Bang-Big Crunch optimization technique. The BBBC technique is suitable for any number of levels. With the help of this technique third, fifth, seventh and ninth level harmonics have been eliminated. Simulation work is done in MATLAB software and the experimental results validates the theory. © 2016 IEEE.

Nonlinear refraction based optical limiting phenomena is investigated analytically in the transmission mode of a fiber Bragg grating using coupled mode theory. A simple expression for intensity dependent transmittivity has been obtained by incorporating the Kerr effect in nonlinear coupled equations. The transmission is studied as a function of the incident intensity at various incident wavelengths. We have found that the transmittance of the grating gradually increases as a ramp function and becomes constant after a critical intensity when the wavelength of the incident light is tuned above the Bragg wavelength. © 2012 World Scientific Publishing Company.

A vast rural Indian population is dependent on the supply of untreated water, which is the root cause of their ailments. The rural population is thriving on the contaminated water supply due to lack of financial resources and other pressing essentialities of life. Safe water is vital for improving the health and quality of life and for alleviating poverty. In the process of developing a plant based substitute for economical safe approach for water purification against conventional chemical constituents, plants were screened for evaluation of their efficiency for antibacterial activity. Ocimum sanctum is effective against Escherichia Coli, Salmonella typhi, Pseudomonas pyocyaneus, Vibrio Cholerae, Shigella dysenteriae and Proteus Vulgaris within specified contact time. O. sanctum is effective against Escherichia Coli with increase in specified contact time.

Implementation of Fuzzy Logic in sugar industry will provide a new method to overcome various problems and increase the overall efficiency of sugar industries. The fuzzification, rule base and defuzzification are the key elements of a fuzzy system. Apart from fuzzification and defining rule there are numerous ways of defuzzification. This paper deals with the analysis and a comparative study of different deffuzification methods used for a three input fuzzy controller. The fuzzy controller developed and simulated for different deffuzification method by using Fuzzy Tool Box provided by MATLAB version 7.7 (R2008b). © 2015 IEEE.

Lexical analysis is the first and foremost step in the compilation process. The basic aim of this step is to convert stream of characters / symbols into words called tokens. These tokens are used by the other phases of a compiler. Many tools have been developed in the past that generate the tokenizer automatically. These tools are best suited for sequential processing. With the advent of multi-core processors it is possible to parallelize tokenization by exploiting the parallel constructs of the languages. In this paper we propose a parallel lexical analyzer which exploits loops and processor affinity concept to achieve parallelism in lexical analysis on multi-core machines. The results show substantial improvement in lexical analysis phase as compared to sequential version. © 2012 IEEE.

This paper presents voltage assessment indices for unbalance radial feeder in smart grid application. These indices are voltage stability margin, voltage deviation index, voltage profile and voltage unbalance factor. Voltage assessments are based on unique two-bus Π-network model having time varying composite voltage sensitive load for every 15 mintues. Each node of feeder have three different time varying load categories consumers (industrial, commercial and residential), which is more practical to actual feeder. Characteristics and composition of residential, industrial and commercial consumers are accounted through time varying static composite load models. Composite load modelling is combination of constant impedance, constant current and constant power. The load flow solution is based on two port network modeling, load modeling and forward- backward sweep technique. Developed indices were calculated for modified IEEE 37 node test feeder with consideration of 15 minutes characteristics time interval for load modeling to meet out requirement of smart grid implementation. Simulation results demonstrate the validity and effectiveness of proposed indices for smart grid applications. © JES 2015.

To detect the occurrence of islanding events as it becomes a challenging issue, the wavelet transform technique is approached. This technique has grasped to detect the appearance of islanding events in a highly effective manner. The proposed approach would serve as an efficient aid such that the mains power disconnection can be better distinguished. The islanding occurs when a portion of the distribution system becomes electrically isolated from the remainder of the power system yet continues to be energized by distribution generators. The current industry practice is to disconnect all distributed generator immediately after the occurrence of islands. To achieve such a goal, each distributed generator must be equipped with an islanding detection device, which is also called anti islanding devices. This paper proposes a wavelet based passive islanding detection scheme. This paper utilizes the discrete wavelet transform to detect the islanding contingency on grid with conventional method of voltage change and frequency change detection. Simulation results supported the effectiveness of the method for the application considered. The detection technique results indicate that the method can detect the islanding correctly and promptly. © 2012 IEEE.
