pinch technology is one of the best methods for designing a multi stream heat exchanger(mshe) through a network; current pinch-based methods, however, lead to a larger and more complicateddesign problems. the major drawback of the current methods is they result in designs having more individual mshe sections than essential, correspond to the enthalpy intervals on temperature vs. enthalpy diagra...

یکی از روش های ارزیابی لرزه ای پل ها استفاده از منحنی های شکنندگی تجربی است. از اطلاعات خسارت موجود برای برقراری رابطه بین حالت حدی خسارت و مؤلفه های حرکت زمین استفاده می شود. از آنجا که ویژگی های هیچ کدام از حرکت ورودی و مصالح سازه ای نمی توانند به طور قطع بیان شوند، مطالعات آسیب پذیری احتمالاتی با استفاده از روابطی که احتمال خسارت را به صورت تابعی از متغیرهای اتفاقی حرکت زمین و خصوصیات مصالح ...
Since 2000 pairings became a very useful tool to design new protocols in cryptography. Short signaturesand identity-based encryption became also practical thanks to these pairings.This thesis contains two parts. One part is about optimized pairing implementation on different ellip-tic curves according to the targeted protocol. Pairings are implemented on supersingular elliptic curve...
This paper deals with the problem of multi-degree reduction of a composite Bézier curve with the parametric continuity constraints at the endpoints of the segments. We present a novel method which is based on the idea of using constrained dual Bernstein polynomials to compute the control points of the reduced composite curve. In contrast to other methods, ours minimizes the L2-error for the who...
This paper provides computationally tractable conditions to determine whether a composi te splme curve or patch selfintersects, according to a definition that includes the important limiting cases of cusps, singularities, and tangential intersections of adjacent components . These results follow upon our exposit ion of necessary and sufficient conditions to preclude such selfintersections. The ...
