Micro-hydro-electric power is both an efficient and reliable formof clean source of renewable energy. It can be an excellent method of harnessing renewable energy from small rivers and streams. The micro-hydro project designed to be a run -of-river type, because it requires very little or no reservoir in order to power the turbine. The water will run straight through the turbine and back into t...

-The integration of Soft Computing techniques in traditional real-time systems is a promising approach to cope with the growing complexity of real-world applications. A power station is a complicated multivariable controlled plant, which consists of boiler, turbine, generator, power network and loads. The demands being placed on Control & Instrumentation engineers include economic optimization,...

Power generation today is an increasingly demanding task, worldwide, because of emphasis on efficient ways of generation. A power station is a complicated multivariable controlled plant, which consists of boiler, turbine, generator, power network and loads. The power sector sustainability depends on innovative technology and practices in maintaining unit performance, operation, flexibility and ...

This paper describes the optimization of maintenance workforce scheduling at Afam power station in Nigeria. The objective is to determine the optimum schedule to satisfy growing maintenance labour requirements with minimum cost and highest efficiency. Three alternative maintenance workforce schedules are compared. The first alternative is to continue with the traditional five-day workweek sched...

the main objectives of this paper are measuring the technical efficiency of iranian thermal power plants and investigating the determinants of technical efficiency levels in these plants. stochastic nonparametric envelopment data (stoned) method applied to plant-level data over a period of thirteen years from 1999 to 2011. this is the first comprehensive analysis (to our knowledge) of technical...

Mobile communication is more vulnerable to security attacks such as interception and unauthorized access than xed network communication. To overcome these problems, many protocols have been proposed to provide a secure channel between a mobile station and a base station. However, the public-key based protocols are not fully utilized due to the poor computing power and the small battery capacity...

All rights reserved Effective simulations to ensure optimal performance and correctly predict the hydraulic and thermomechanical behaviour of today’s huge boiler feed water pumps are a challenge for engineers and constructors. Generally, boiler feed water pumps are subjected to extreme mechanical and thermal stresses because of their huge siz...

Planning and dimensioning process of a multi-service network WCDMA should consider the whole parameters characterising the radio cell. Among these, we are interested in the required total BTS power and maximum capacity supported by the cell in the downlink direction. This direction requires more radio resources, thus it is more delicate to optimize. In this context, we express these two paramet...

The Compact Linear Fresnel Reflector (CLFR) is a linear-concentrating solar thermal energy system currently in the prototype stage at the Liddell power station in the Hunter Valley, NSW. A system-level thermo-fluidic model for the CLFR has been developed in order to predict steady-state operating conditions, required pumping power and pressure, mass transfer around the system and likely startup...
