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 …

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 …

محیط اقتصاد کلان و روانشناسی ارزیابی کار This research tested the idea that the perception of the state of the macroeconomic environment impacts the psychology underlying an essential organizational function: The evaluation of employees’ work and the associated promotion and demotion decisions. We predicted that when the macroeconomic environment is …

مدل سازی، تحلیل و کاهش مخاطرات در سیستم های مالی Recent financial turmoil (e.g., the 2008–2009 global financial crisis) has resulted in financial contagion-induced instability becoming one of the major concerns in the fields of economics and finance. In this paper, we extend the network analysis of financial contagion from …
