In this paper, the performance of an ejector cooling system and the effect of the following different working fluids such as water, ammonia, R134a, R141b, R12, R600 and R245fa are described and the effects of cycle parameters on the consumed heat and work and COP are studied. This cycle with the working fluid R141b has the least COP while the working fluid R₁₂ in comparison with the other worki...

This paper describes the LISA system which is a generic interactive environment for programming language development. From the formal language specifications of a particular programming language LISA produces a language specific environment that includes a languageknowledgable editor, a compiler/interpreter and other graphic tools. The paper focuses on design decisions, implementation issues an...

In the restructured environment of electricity market, firstly the generating companies and the customers are looking for maximizing their profit and secondly independent system operator is looking for the stability of the power network and maximizing social welfare. In this paper, a one way auction in the electricity market for the generator companies is considered in both perfect and imperfec...

Earlier static ID and Password are used which is vulnerable against eavesdropping and replay attack. To overcome this problem One Time Password technique is used which give different password each time. Earlier OTP is HOTP which is based on one way hash function SHA-1 and Ping Pong-128 stream cipher. In this paper we propose a method of generating OTP by using Genetic Algorithm with Elliptic Cu...

This study addresses the problem of controlling a variable- speed wind turbine with a doubly fed ‎induction generator (DFIG) by control System that called One-Cycle control (OCC). Generator-side converter regulator speed and Grid-side converter controls reactive power and voltage of the DC-Link. Proposed method under different conditions such as load change, fault and nonlinear loads are studie...
