A designing pattern provides generic idea of a solution to solve a recurring problem with variety of goals and constraints. In object oriented program, design patterns are recognized by source code. This paper provides overall idea about design patterns, different types of analysis and their comparison details with detection techniques of pattern. It also explains how it is related with non functional requirements in improving the quality of pattern. © 2014 IEEE. Source

In this paper, we study the existence, uniqueness, continuous dependence, Ulam stabilities and exponential stability of random impulsive semilinear differential equations under sufficient condition. The results are obtained by using the contraction mapping principle. Finally an example is given to illustrate the applications of the abstract results. © 2014 Wuhan Institute of Physics and Mathematics. Source

Herbs are considered to be the backbone of traditional medicines from Hispanic days. About 80% of the World's population depends on the traditional medicines for various ailments. With this background, the present investigation was concentrated on the screening of bioactive components of Tagetes erecta L. The GC-MS analysis of dried leaves and flower samples were carried out using GC-MS-QP 2010 model with methanol as solvent. Around 19 and 31 phytochemicals were registered in leaf and flower samples, respectively which have high therapeutic value in the commercial available drugs. Source

Owing to the increasing cost of petroleum products, fast depletion of fossil fuel, environmental consideration and stringent emission norms, it is necessary to search for alternative fuels for diesel engines. The alternative fuel can be produced from materials available within the country. Though the vegetable oils can be fuelled for diesel engines, their high viscosities and low volatilities have led to the investigation of its various derivatives such as monoesters, known as bio diesel. It is derived from triglycerides (vegetable oil and animal fates) by transesterification process. It is biodegradable and renewable in nature. Biodiesel can be used more efficiently in semi adiabatic engines (Semi LHR), in which the temperature of the combustion chamber is increased by thermal barrier coating on the piston crown. In this study, the piston crown was coated with ceramic material (TiO2) of about 0.5 mm, by plasma spray method. In this present work, the experiments were carried out with of Pongamia oil methyl (PME) ester and diesel blends (B20 & B100) in a four stroke direct injection diesel engine with and without coated piston at different load conditions. The results revealed 100% bio diesel, an improvement in brake thermal efficiency (BTE) and the brake specific fuel consumption decreased by about 10 % at full load. The exhaust emissions like carbon monoxide (CO) and hydrocarbon (HC) were decreased and the nitrogen oxide (NO) emission increased by 15% with coated engine compared with the uncoated engine with diesel fuel. The peak pressure and heat release rate were increased for the coated engine compared with the standard engine. © 2013 The Korean Society of Mechanical Engineers and Springer-Verlag Berlin Heidelberg.

African marigold (Tagetes erecta) has been used for medicinal purposes since prehispanic times. The various parts of the plant such as stem, leaf, flower and root were subjected to analysis the qualitative phytochemical constituents with two different solvents (ethyl alcohol and petroleum ether). About sixteen phytochemicals analysis were carried out, out of which six phytochemicals were identified in both the solvents predominantly. Source
