. فیلتر پیشنهادی دارای فرکانس قطع db 3- در 2.38 ghz و باندگذر این فیلتر، از باند عبور به باند قطع که معمولاً از فرکانس قطع db 3- تا فرکانسی که در آن میزان تضعیف به db 20- میرسد برابر با ghz 0.45است. باند قطع این فیلتر با میزان تضعیف db 21- از ghz 2.5 تا23.5ghz است. insertion loss در باند عبور کمتر از db 0.1 و return loss در باند عبور بهتر از db 16. 9- و در باند قطع نزدیک به 0 db میباشد که نشا...
translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
An experimental and numerical investigation is performed into the power loss induced in grooved polymer optical fibers (POFs) subjected to combined bending and elongation deformations. The power loss is examined as a function of both the groove depth and the bend radius. An elastic-plastic three-dimensional finite element model is constructed to simulate the deformation in the grooved region of...
This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...

deregulation policy has caused some changes in the concepts of power systems reliability assessment and enhancement. in this paper, generation reliability is considered, and a method for its assessment using intelligent systems is proposed. also, because of power market and generators’ forced outages stochastic behavior, monte carlo simulation is used for reliability evaluation. generation r...
