Multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. In this paper, a new clustering based multi path routingprotocol namely ECRR (Energy efficient Cluster based Routing algorithm for improving Reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required QoS ...
Cross efficiency is a method with the idea of peer evaluation instead of self-evaluation, and is used for evaluation and ranking Decision Making Units (DMUs) in Data Envelopment Analysis (DEA). Unlike most existing DEA ranking models which can only rank a subset of DMUs, for example non-efficient or extreme efficient DMUs, cross efficiency can rank all DMUs, even non-extreme ones. However, sinc...
For more than three decades, Oxidative Coupling of Methane (OCM) process has been comprehensively investigated as an attractive alternative for the commercially available ethylene production technologies such as ethane and naphtha cracking. Developing a suitable catalyst and proper reactor feeding policy, reviewing and deploying the efficient methods in the separation and purification of the un...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
هدف از انجام این مطالعه بررسی تاثیر آموزش متناوب بر پیشرفت یادگیری گرامر زبان آموزان بوده است. بدین منظور، 60 زبان آموز سطح پیش ازمتوسطه از میان 90 نفر بر اساس نتایج به دست آمده در آزمون پایلوت شده ket انتخاب شدند. این زبان آموزان به طور تصادفی در دو گروه شامل یک گروه آزمایشی و یک گروه کنترل هر کدام متشکل از 30 نفر قرار داده شدند. سپس زبان آموزان هر دو گروه درآزمون گرامر معلم ساخته که به عنوان ...
Simulation is a useful tool for engineering systems, and it is used in numerous and diverse fields. Simulation of large systems can result in better designs and make the design process more efficient. One important use of simulation lies in comparing and choosing the best among different simulation models that represent competing or alternative designs before the actual deployment and implement...
