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.

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.

A Maximum power point tracking (MPPT) allows the photovoltaic module to operate at its maximum power point. It is done using a converter that regulates the power that is drawn from the converter. By varying the duty cycle of the switches, the energy transferred through the converter can be precisely controlled. This paper deals with simulation of estimator for a digital tracking system used for simulation of maximum power point PV tracker using KALMAN Filter. For the simulation Back-Propagation and Radial Basis Network are used as Artificial Neural Network (ANN) tool. The objective of this paper is to discuss the use of KALMAN filter as an estimator in the area of photovoltaic cell power tracking.

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.

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.
