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 …

چگونه باید مالیات برای تشویق کارآفرینی طراحی شود؟ This paper examines how tax policy should be designed to best encourage entrepreneurial activity in start-up firms. We begin by describing several presumed market failures affecting entrepreneurial firms that would lead to an under-provision of entrepreneurial activity: 1) information spillovers from innovations …

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 …

مواد بیولوژیک بیولوژیک و الکترومغناطیسی مبتنی بر پلیانیلن برای تحریک الکتریکی Polyaniline (PANI) involved materials have extended approved applications in different fields, including bio/chemical-sensors, electrical and electrochemical devices, electrochemically active membranes and stimuli-responsive systems. These materials have attracted most of the interest in the field of development of biomaterials for …

روش های جدید هوش مصنوعی در مهندسی ساخت و ساز Artificial intelligence (AI) is proving to be an efficient alternative approach to classical modeling techniques. AI refers to the branch of computer science that develops machines and software with human-like intelligence. Compared to traditional methods, AI offers advantages to deal …

دستگاه طیف سنج برای یادگیری فعال در آموزش مهندسی زلزله Structural and geotechnical engineers regularly use response spectra to assess the response of civil infrastructure to earthquakes; however, the underlying concepts of response spectra are often difficult for civil engineering students to grasp. Hardware specifications for two low cost response …
