The drive for greater productivity
نویسندگان
چکیده
resources in a world of increasing demand. Dwindling oil and gas reserves mean the days of accessing easy hydrocarbons are all but over. With the downturn in the economy, many companies are trying to boost productivity by implementing costsaving measures, increasing work efficiency and by being more environmentally friendly. Indeed striving to improve productivity and eco-efficiency may be the only sustainable path through what are increasingly volatile markets. Success partly depends on redefining cooperation and partnerships, and by using technology as the enabler.

Modern Topology& Thermal Analysis of Drive for Variable Speed Pumped Storage Power Plant
Given the significant power generation and consumption of variable-speed pumped storage power plants (VSPSPs), it is crucial to enhance drive methods and decrease drive losses, thereby increasing productivity. This paper proposes the topology for VSPSP drivers with two level voltage source converters (2LVSC) with 6+1 converters. Hydraulic and electrical VSPSP models are presented, following whi...
متن کاملInvestigating Agricultural Productivity Growth and Convergence in Iran and Eastern African Countries
The issue of convergence or divergence of productivity has important policy for regional poverty reduction and increasing standards of living. If productivity converges to a common level without intervention, there is little need for explicit policies in lagging regions to promote catch up. On the other hand, productivity has divergence trend, then explicit policies would be needed to prevent f...

متن کاملMalmquist productivity index in several time periods on interval data
The productivity change of a decision making unit (DMU) between two time periods can be evaluated by the Malmquist productivity index. In this study, we propose a method to compute the Malmquist productivity index in several time periods (from the first to the last periods) on interval data in data envelopment analysis (DEA). Then, the obtained Malmquist productivity index is compared with Malm...
متن کاملan Efficient Drive Circuit for Switched Reluctance Motor
The purpose of this paper is to present an efficient converter circuit used to drive switched reluctance motors. It uses the C-dump topology in which the trapped energy in the phase windings is returned to the supply capacitor to be used in the following strokes. In addition to the C-dump topology, it uses two extra feedbacks. One comes from a governor mounted on the shaft of motor which contro...
