INTRODUCTION The subject of economic growth and equitable distribution of income of any country is an economically important one. The fulfillment of economic development in each country is based on achieving two goals‚ including fairly rapid economic growth and income distribution in society. More growth and better distribution is not possible at the same time-some economist argued. So it needs to make trade-off. The issue of growth and income distribution is very much concerns to the economist and it is

Rating for Load Compensation With Nonstiff Source Srinivas Bhaskar Karanki‚ Nagesh Geddada‚ Student Member‚ IEEE‚ Mahesh K. Mishra‚ Senior Member‚ IEEE‚ and B. Kalyan Kumar‚ Member‚ IEEE Abstract—The distribution static compensator (DSTATCOM) is used for load compensation in power distribution network. In this paper‚ a new topology for DSTATCOM applications with nonstiff source is proposed. The proposed topology enables DSTATCOM to have a reduced dc-link voltage without compromising the compensation

How Distribution Is Arranged To Provide Customer Convenience? There are several ways in which businesses arrange distribution to provide customer convenience. The methods used may vary slightly based on what sort of business is being operated. For example‚ those who are running an e-commerce business will have different techniques than those who have a standard "real world" business headquarters.
