Shape Matching is an important aspect in image processing . It is an important step whenever there arouses a need to match a certain image with another . There are a lot of applications wherein the image matching is the key step towards the fulfillment of the application. So in such cases Partial image matcing usually becomes a crucial part of the whole process. Hence here we present a novel approach of partial shape matching for the scale invariant images. The problem of establishing a match between an open contour and a closed contour is tried to resolve in this paper. The computation of the shape descriptors is alo done along open or closed contours. The net ordered collections of shape descriptors constitute the global shape representation. Here we propose an alternate technique to an existing Dynamic time warping matching technique for the matching of the shape representation. Use of the properties of the employed shape descriptor, sampling scheme and matching procedure, the proposed approach performs partial shape matching that is invariant to Euclidean transformations. Also the problem of matching the closed to closed contours is automatically treated as a special case. The proposed method gives a better vision and a better result as compared to that of existing system because of the extensive dataset used in the proposed application. And thus the proposed system is a better solution of partial shape matching and the problems related to partial shape matching

Portland cement concrete industry has grown astronomically in recent years. It will continue to grow as the result of continuous urban development. However, Portland cement concrete posses problems such as durability and carbon dioxide emission. Many concrete structures have shown serious deterioration, way before their intended service life, especially those constructed in a corrosive environment (Mehta 1997). Geopolymer is a class of aluminosilicate binding materials synthesized by thermal activation of solid aluminosilicate base materials such as fly ash, metakaolin, GGBS etc., with an alkali metal hydroxide and silicate solution. These binders are currently attracting widespread attention due to their potential utilization as a high performance, environmental friendly and sustainable alternative to Portland cement India being the largest coal fly-ash producer in the world produces abundant by- product from thermal power plant known as coal fuel ash Based on the mixture design process eighty one test cubes of 150x150x150mm of low-calcium fly ash-based geopolymer concrete were cast to study the effect of various parameters on compressive strength of low-calcium fly ash-based geopolymer concrete. Keywords: - Geopolymer concrete, Characteristic strength, Fly ash, Superplasticizer.

Vertical axis wind turbines (VAWTs) were originally considered as very promising for various reasons. There is now a resurgence of interests for VAWTs, in particular Darrieus turbines. Using modern design tools and computational approaches, it is possible to increase considerably the performance of traditional VAWTs, reaching a level almost comparable to that of horizontal axis turbines. Since VAWTs show many specific advantages (compact design, easier connection to gears/generator, easier blade control if needed, lower fatigue.), it is important to check quantitatively the efficiency of such turbines. In the present study, a barrier has been designed to increase the performance of the Darrieus wind rotor. The effect of this barrier on the rotor performance has been analyzed numerically; the barrier has been placed in front of the rotor. Numerical analysis has been carried-out forDarrieus wind rotor (with and without barrier). The power performance values of the rotor have been calculated by numerical analysis, and finally they have been compared. The obtained results show that higher performance when using the rotor with barrier. Finite Element analysis (FE) has been used as the Computational fluid dynamics(CFD) software.

Cloud Computing is an emerging paradigm in the area of parallel and distributed computing. Clouds consist of a collection of virtualized resources, which include both computational and storage facilities .It facilitates users to access shared computing resources through internet on demand. The main purpose to search on this paper to get the deep knowledge about the scheduling mechanisms of cloud computing, also to get their comparisons. The scheduling mechanisms of cloud computing are based on performance and cost evaluation, resource scheduling, task scheduling.

Refrigeration can be described as a remarkable achievement of science. The use of some refrigerants such as CFCs and HCFCs are harmful to the environment and depletes the ozone layer which protects the Earth from radiation. And facilitates global warming. The investigation of hydrocarbons - butane as refrigerant that is environmentally friendly, with zero ozone depletion potential (ODP), global warming potential (GWP) less than three. This will also help provide an alternative use to the hydrocarbons – butane being flared from refineries and crude oil drilling sites.

In this work,mixed convection MHD flow of nanofluid over a non-linear stretching sheet with thermal radiation and suction and variable magnetic field is investigated. An analysis of the results shows that the velocity and thermal fields are influenced appreciably by the magnetic field,effective Prandtl number, local Grashof number, Eckert number, power-law stretching parameter and nanoparticles volume fraction. Solutions are presented for velocity and temperature fields for various values of magnetic field and suction parameters. Thermal boundary layer equation takes into account of viscous dissipation and Ohmic dissipation due to transverse magnetic field and electric field.
