Abstract

As time's progressing we are getting highly accustomed to mobiles, laptops, ipod's, and iphones. In fact, charging all these appliances has become so very cumbersome. Now each appliance has its own set of chargers, and with every family member owning their cell phones, the drawers are overflowing with all sorts of wires. When we are on the way to work and our cell phone beeps in hunger for a battery charge, haven't we wished for our cell phone battery to get self charged. Well, this dream is to be fulfilled by wireless electricity Transmission of power without using wires. It is basically based on piezo-electric effect.the study of piezo materials enables us to think of its various application one among them is wireless power transmission. The piezo materials generate vibrations upon change in its dimensions through stress by applying voltage etc. and the converse of it is also true (vibrations as input, voltage as output) by utilizing this property the power to various charging devices can be transferred efficiently. The device can be charged within a range of 8m without connecting statically into power socket. This paper mainly emphases on charging of various battery operated devices using peizo electric effect without using wires.

Abstract

Green computing is the study and practice of using computing resources efficiently. Green Computing is one of the hottest subjects these days for people in industry, academia and even for businesses. The major benefits of using Green Computing (including energy-aware, and power-aware) is not perfectly clear in terms of monetary cost, performance, and the amount of pollutants such as carbon footprint. This paper mainly discusses why we need green computing and approaches to green Computing. This paper also discusses some of the recent implementations of green computing. The main aim of this paper is to reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability of defunct products and factory waste. The plan towards green IT should include new electronic products and services with optimum efficiency.

Keywords

Abstract

The aim of the project is to design a new class leaf spring by using functionally graded material and functionally graded structural concept. Analysis is done on leaf spring of different materials having high structural strength and damping capacity. We know that every material does not have both the properties. We can achieve both properties in composite materials but we can't use it for heavy vehicles and also it is costly. We can also achieve the both properties in conventional material leaf spring by applying the concept of FGM & FGS. In static analysis deformation, stress, strain can be found out. Modal analysis is done to find natural frequency. With optimization in design & material we can determine best quality of leaf spring structure. The modelling of the leaf spring has been done in solid works. Finite analysis of the leaf spring is carried out in ansys 14.5 work bench.
