energy absorbing bumpers technical seminar ppt

A bumper is a structure attached or integrated to the front and rear of an automobile to absorb impact in a minor collision, ideally minimizing repair costs.Bumpers also have two safety functions: minimizing height mismatches between vehicles, and protecting pedestrians from injury.British inventor Frederick Simms imagined the bumpers in 1901.Bumpers of most modern automobiles have been made of a combination of polycarbonate (PC) and Acrylonitrile butadiene styrene (ABS) called PC ....etc

matlab code energy based spectrum sensing in cognitive radio energy threshold based algorithm

ABSTRACT

Spectrum sensing is the basic and essential mechanisms of Cognitive Radio (CR) to find the unused spectrum. This paper presents an overview of CR architecture, discusses the characteristics and benefits of a CR. Energy detection based spectrum sensing has been proposed and used widely because it doesn't require transmitted signal properties, channel information, or even the type of modulation. In this paper, a survey of energy detector over ....etc

NON CONVENTIONAL ENERGY SOURCES
Abstract
The ever increasing rapid use of the fossile fuels day by day has threatened exhausting of conventional energy sources very soon. Also the use of conventional energy sources has increased the global pollution level which is resulting in climate change. Therefore time has come for searching altogether other sources of energy which are inexhaustible and gradually replace the conventional sources. The non conventional energy sources such as solar, wind, tidal, oce ....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 r ....etc

Embedded Energy Meter- A New Concept To Measure The Energy Consumed By A Consumer And To Pay The Bill

ABSTRACT
In this paper, a new concept of energy meter will be discussed, where maximum demand of energy of a consumer will be indicated in the meter used by the consumer. After exceeding the maximum demand, the meter and hence the connection will automatically be disconnected by an embedded system inserted in the meter itself. According to the maximum demand, the consumer will purchase a cash-card of amount depending on the consumpt ....etc
