Swimming pools provide a great way toexercise and beat the summer heat. Buildingand maintaining a pool, however, alsomeans relatively high costs added to yourhousehold’s budget. There are severalways that you can reduce operating andmaintenance costs, lower water consumption,and conserve heat if you heat yourpool. Many people heat their pools toextend the swimming season and/or tokeep it at a temperature that they are personallycomfortable with. This lets themenjoy the full value from their pool. Solarpool heaters are an option ....etc

ABSTRACT

Target search in content-based image retrieval (CBIR) systems refers to finding a specific (target) image such as a particular registered logo or a specific historical photograph. Existing techniques, designed around query refinement based on relevance feedback, suffer from slow convergence, and do not guarantee to find intended targets. To address these limitations, here propose several efficient query point movement methods. here prove that our approach is able to reach any given target image with fewer iterations in the worst and ....etc

DC System Technologies for Large Scale Integration of Wind Energy Systems with Electricity Grids
Abstract:
The ever increasing development and availability of power electronic systems is the underpinning technology that enables large scale integration of wind generation plants with the electricity grid. As the size and power capacity of the wind turbine continues to increase, so is the need to place these significantly large structures at off-shore locations. DC grids and associated power transmission technologies provide opportuniti ....etc

Abstract:
The oil shocks of 1970s led to spiraling crude oil prices in the world market which prompted planners to view energy security as an issue of national strategic importance. Energy security has an important bearing on achieving national economic development goals and improving the quality of life of the people. World’s dependence on crude oil will continue for most part of the 21st century but the continued dependence on crude oil is loaded against it with inherent price volatility linked to finite global ....etc
