In this paper the effect of water mass on the performance of triangular pyramid solar still with and without latent heat energy storage was experimentally investigated. For comparing the productivity of solar still with and without LHTESS a solar still is designed, fabricated. Experiments are conducted in hot and humid climate of Chennai, India. It is found that there is an increase of production of fresh water with decrease in water mass. There is an increase of about 35% in production of fresh water with LHTESS than that of solar still without LHTESS. Also it was found that during the off shine period the fresh water produced from the still is higher compared to higher water mass. The solar still with and without LHTESS were found to be 5.5 L/m2day and 3.5 L/m2day. © 2014 Published by Elsevier Ltd.

The conventional controller suffers from uncertain parameters and non-linear qualities of Quasi-Z Source converter. However they are computationally inefficient extending to optimize the fuzzy controller parameters, since they exhaustively search the optimal values to optimize the objective functions. To overcome this drawback, a Particle Swarm Optimization based Fuzzy controller parameter optimization is presented in this paper. The proposed algorithm is used to find the optimal fuzzy parameters for minimizing the objective functions. The feasibility of the proposed technique has been simulated and tested. The results are bench marked with conventional fuzzy controller and Genetic Algorithm for Quasi-Z Source Converter. The results of the DC/DC Converter for several existing methods illustrate the effectiveness and robustness of the proposed algorithm. © 2015, The Korean Society of Automotive Engineers and Springer-Verlag Berlin Heidelberg.

In this study, the effect of geometry on the performance of a tetrahedral solar still was experimentally investigated on Chennai climatic conditions. In this work, a solar still of area 0.95 m2 and a glass cover in a triangular form was designed and fabricated. Environmental parameter includes solar intensity, ambient temperatures, and wind speed. Operational parameters are feed water quantity and orientation. Tests were conducted in Hindustan Institute of Technology and Science, Kelambakkam, Chennai, India. The maximum distillate output found was 4.3 lm-2day-1. The results shows that the production of fresh water was increase up to 40% compared to that of other conventional solar stills.

Generally two methods are followed to get the maximum power from solar photo voltaic panel. These are electrical maximum power point tracking technique (MPPT) and mechanical maximum power point tracking technique. These methods are having some complicated control and drive circuits for implementation and also it need extra power. To get better performance, higher cost and regular maintenance is needed. So it is not suitable for implementation in rural areas since regular maintenance is not possible in those areas, due to many reasons. This paper gives a solution for using solar photovoltaic system in such rural areas without more maintenance and also this system gives more power without sun tracking system. In sun tracking system, more power is required for motor drives and also need complicated algorithm. Without sun tracking, electrical MPPT technique is not only enough to get the optimization power throughout the whole day. In this paper, use modified structure solar panel and reflector. So the power output is increased and the comparison of the experimental result proves that modified panel with reflector increases the power output. © 2014 IEEE.

Multiprocessor task scheduling is a key research area in high performance computing. The problem of optimally allocating a set of real time tasks that can be assigned to processors, without violating the deadlines, is a NP-Complete problem. This problem has assumed current importance due to the advent of the multi core architecture. The parameters normally used to compare the various scheduling algorithms are the length of the makespan, utilisation of the processor, cache performance, power consumption, workload balance, and scheduling penalties and switch cost. This survey reports the various approaches adopted till date for real time task scheduling in multiprocessors. © 2012 EuroJournals Publishing, Inc.

Scheffler fixed focus concentrators are used for medium temperature applications. These concentrators are lateral sections of paraboloids and provide fixed focus away from the path of incident beam radiations throughout the year. In this paper design of a Scheffler Solar Concentrator system and it’s thermal characterisation is presented. In the second part of the papar thermal characterization of a flat plate collector is presented which was done under identical conditions as the scheffler concentrator. In case of flat plate collector efficiency is high in the low temperature region (500C to 800C) while that of point focus concentrator was found to be low and in subsequent temperature range (800C to 1500C) it increases and remains stable almost throughout the range. By super imposition of two performance curves, system of flat plate with scheffler may give a stable higher efficiency throughout the range of low to medium temperature range (500C to 1500C) © Research India Publications.

We consider that Rough Sets that arise in an Information System from the point of view of Topology. The main purpose of this paper is to show how well known topological concepts are closely related to Rough Sets and generalize the Rough sets in the frame work of Topological Spaces. We presented the properties of Quasi-Discrete topology and Π0-Roughsets. © Springer International Publishing Switzerland 2014.

Image segmentation is a decomposition of scene into its components. It is a key step in image analysis. Edge, point, line, boundary, texture and region detection are the various forms of image segmentation. In human visual Systems, edges are more sensitive than other picture elements. Edge detection technique when used alone for image segmentation results in small gaps in edge Boundaries to any of the neighbouring pixels. A new supervised method for segmentation of blood vessels in retina photographs is implemented in the project. The purpose of this method is to automate the retinal image analysis. Using the retinal image analysis the retinal abnormality can be detected, to diagnose the retinal blood vessel features which is linked to systemic disease. The morphological segmentation is used the cardiovascular and coronary disease in adult life. The algorithm described here is for integrating edges and regions. Firstly, the edge map of image is obtained by using kirsch edge operator. The algorithm is implemented in MATLAB and the result demonstrates that the algorithm is robust, satisfying and work well for images with non-uniform illumination. © 2013 IEEE.

This paper gives an insight of how we can uncover additional value from the data generated by healthcare and government. Large amount of heterogeneous data is generated by these agencies. But without proper data analytics methods these data became useless. Big Data Analytics using Hadoop plays an effective role in performing meaningful real-time analysis on the huge volume of data and able to predict the emergency situations before it happens. It describes about the big data use cases in healthcare and government. © 2015 The Authors. Published by Elsevier B.V.

Pattern matching or finding the occurrences of a pattern in a text arises frequently in many applications. The task of splitting the character stream or text into words is called tokenization. Search engines use tokenizers. The first phase of a compiler outputs a stream of tokens of the given high-level language program. The pattern rules are specified as regular expressions. Many tools have been developed in the past that generate the tokenizer automatically which are mostly sequential. The advent of multicore architectures has made it mandatory to use its features like multiple threads and SIMD instructions in generating software tools. This works attempts to parallelize tokenization. This is a simple prototype implementation of a parallelized lexical analyzer that recognizes the tokens of the given source code. Each Synergetic Processing Element(SPE) of the cell processor works on a block of source code and tokenizes them independently. The Power Processing Unit(PPE) is responsible for splitting the source code into a finite number of blocks to be used by the different processing elements. Each SPE sends the stream of identifiers to the PPE which maintains the symbol table. The parallel lexical analyzer developed runs on IBM Cell Processor simulator and the execution times are plotted varying the code size and the number of processing elements. © 2010 IEEE.
