تسهیلات برنامه ریزی خطی برای حل مشکلات برنامه نویسی چند جمله ای This paper studies linear programming (LP) relaxations for solving polynomial programming problems. A polynomial programming problem can be equivalently formulated as a quadratically constrained quadratic program (QCQP) by introducing new variables that represent nonlinear monomials and substituting them …

رویکرد نوآورانه برای برآورد مقاومت فشاری ملات داشتن مواد معدنی کلسیم inosilicate There are several factors that can affect on the quality of construction and all of the using elements, such as mortars, as a basic component of the building industry, are effective in the ability and performance of the …

بررسی استراتژی های ساختمان سازی محور محله به منظور کاهش مصرف انرژی ساختمان Building Energy Management is identified as a key part of the move towards localised energy generation and control. The significant discrepancy between building energy use as designed and during actual operation shows a need to evaluate the …

پایه های شناختی و فرهنگی رفتار اخلاقی Does moral culture contribute to the evolution of cooperation? Here, we examine individuals’ and communities’ models of what it means to be good and bad and how they correspond to corollary behavior across a variety of socioecological contexts. Our sample includes over 600 …

شبکه تعادل کاربران باتری خودروهای برقی با توجه به مصرف برق وابسته به جریان This paper addresses the equilibrium traffic assignment problem involving battery electric vehicles (BEVs) with flow-dependent electricity consumption. Due to the limited driving range and the costly/time-consuming recharging process required by current BEVs, as well as the …

یک شرایط بهینه مطلق برای تولید ستون در برنامه های خطی صفر Column generation is a linear programming method that, when combined with appropriate integer programming techniques, has been successfully used for solving huge integer programs. The method alternates between a restricted master problem and a column generation subproblem. The …

کاهش GHG محصولات بتنی راه آهن با استفاده از عامل حفاظت از محیط زیست و بتن This study investigated the life cycle greenhouse gases (GHG) mitigation effect of railway infrastructure through the application of an eco-concrete, using ground granulated blast furnace (GGBF) slag and electric arc furnace (EAF) slag as …

تعیین عددی عرض بتنی برای سازه های بتنی مقاوم در برابر خوردگی Corrosion-induced deterioration of reinforced concrete (RC) structures results in premature failure of the RC structures. In practice concrete crack width is one of the most important criteria for the assessment of the serviceability of RC structures. It is …

عضویت در سازمان تجارت جهانی و تغییر مالیات مصرفی This paper explores tax policy effects and revenue implications of joining the World Trade Organization (WTO) and its predecessor, the General Agreement on Tariffs and Trade (GATT). It documents that countries joining GATT/WTO after 1990 have implemented tariff-cum-tax reforms, lowering tariff …
