Abstract: 

سرمایه گذاری نقش تعیین کننده ای در رشد اقتصادی دارد. یکی از اهداف اساسی کشورها، دستیابی به رشد اقتصادی و توسعه پایدار می باشد. امروزه حجم قابل توجهی از کار مدیران سرمایه گذاری و همچنین به طور عموم سرمایه گذاران، ساختن پورتفوی کارآمدی از دارایی هاست که اهداف تقاضا را برآورده سازد. در این تحقیق از مدل میانگین - واریانس مارکویتز به همراه محدودیت های عدد صحیح و همچنین یک رویکرد فراابتکاری جدید به نام الگوریتم BIG BANG-BIG Crunch برای تشکیل سبد سهام بهره گرفته شده است. الگوریتم مورد استفاده در این تحقیق با سایر الگوریتم های فراابتکاری نظیر الگوریتم شبیه سازی تبریدی، ژنتیک و ... با استفاده از داده های سهام شاخص های بورس هنگ کنگ، ایران و ژاپن مقایسه شده است و نتایج، حاکی از رقابتی بودن این الگوریتم برای حل مساله بهینه سازی سبد سهام دارند.

Abstract: 

THE phenomenon of natural world is one of THE main concerns of human life and it has traced THE attention of scientists. About THE starting of world, several scientific THEories have been put forward. THE THEory of BIG BANG has is most accepted THEory by cosmologists. According to this THEory, all existing matters and energies in THE world have been compacted in a point about 20 billons ago. All galaxies, stars and planets have came out from this primary explosion. THE holy Quran has paid attention much more on THE very BIG phenomenon of creation and several Verses have reminded this point as THEy called to contemplate on THE creation of heaven and earth. One of THE sings of scientific miracle of Quran is its illustration of how THE world has is created (integration of earth and heaven) which is proved by cosmologists after centuries. Nowadays THE scientific THEory of BIG BANG has no contradiction with Quranic Verses. In this article, we have compared few Quranic Verses with THE scientific contents of cosmology an physical world about THE creation of world and we have analyzed this point. At last, we conclude that since THE realities of Quran is not proved, we can say with scientific suppositions. So, we can not compare between THEses Verses and scientific THEory with certainty that THEse two are same. Though some scholars and interpreters have convinced and claimed that two Verses of Quran (Anbia: 30 &Fussilat 11) have informed 13 centuries ago of what is called now “ BIG BANGTHEory which proved THE miracle of Quran once again. .THE full text of this article is THE Persian language, please for THE view full text, refer to Persian Please click here to view THE full text of this article.

Abstract: 

THE BIG BANG-BIG crunch (BB-BC) algorithm is a popular metaheuristic optimization technique proposed based on one of THE THEories for THE evolution of THE universe. THE algorithm utilizes a two-phase search mechanism: BIG-BANG phase and BIG-crunch phase. In THE BIG-BANG phase THE concept of energy dissipation is considered to produce disorder and randomness in THE candidate population while in THE BIG-crunch phase THE randomly created solutions are shrunk into a single point in THE design space. In recent years, numerous studies have been conducted on application of THE BB-BC algorithm in solving structural design optimization instances. THE objective of this review study is to identify and summarize THE latest promising applications of THE BB-BC algorithm in optimal structural design. Different variants of THE algorithm as well as attempts to reduce THE total computational effort of THE technique in structural optimization problems are covered and discussed. FurTHErmore, an empirical comparison is performed between THE runtimes of three different variants of THE algorithm. It is worth mentioning that THE scope of this review is limited to THE main applications of THE BB-BC algorithm and does not cover THE entire literature.

Abstract: 

THE BIG BANG-BIG Crunch (BB-BC) optimization algorithm is a new optimization method that relies on THE BIG BANG and BIG Crunch THEory, one of THE THEories of THE evolution of THE universe. In this paper, a discrete BIG BANG-BIG Crunch algorithm is presented for optimal design of structures. THE BB-BC is employed to optimize different types of skeletal structures with discrete variables including trusses and frames. THE results demonstrate THE efficiency of THE discrete BB-BC algorithm compared to oTHEr heuristic algorithms.

Abstract: 

IN THE THEORY OF RELATIVITY, THE SPEED OF LIGHT IS THE LIMIT OF SPEED FOR THE MOVEMENT OF MATTER. BUT IN THE GATT ERA THE SPEED GOES MUCH UPPER THAN THIS LIMIT BY COMBINING THE IDEAS OF THESE TWO THEORIES, WE MAY REACH TO THE NEW THEORY ABOUT THE BEGINNING OF BIG BANG AND STEPS TO REACH IT.

Abstract: 

THE BIG BANG-BIG Crunch (BB–BC) method is a relatively new meta-heuristic algorithm which inspired by one of THE THEories of THE evolution of universe. In THE BB–BC optimization algorithm, firstly random points are produced in THE BIG BANG phase THEn THEse points are shrunk to a single representative point via a center of mass or minimal cost approach in THE BIG Crunch phase. In this paper, THE BB–BC algorithm is presented for optimal cost design of water distribution systems and employed to optimize different types of hydraulic networks with discrete variables. THE results demonstrate THE efficiency of THE proposed method compared to oTHEr algorithms.

Abstract: 

Curriculum as THE backbone of THE educational system is one of THE important factors in creating fundamental changes in THE higher education system; THE purpose of this research is to explain THE effectiveness of entrepreneurship education MODEL from THE Islamic point of view and  THE Leader, so that it can be used to examine THE curriculum of architecture education in terms of THE realization of entrepreneurship components in students. THE method of THE current research is a mixed exploratory one, which in THE qualitative part, by examining THE views of THE Leader in his articles, books and speeches, descriptive propositions of his thought regarding THE effectiveness of entrepreneurship education were extracted with THE implication research method. In THE quantitative part, THE data was analyzed using structural equation method and using SPSS20 and smart PLS software. THE findings showed that THE MODEL of entrepreneurship from THE Leader'spoint of view can be divided into four main pillars: vision, knowledge, skill and business. And each of THEse main pillars overlaps with THE MODEL of effectiveness of entrepreneurship education in architecture curriculum. In this way, architecture higher education centers can, in addition to creating entrepreneurship curricula in THE field of architecture, by identifying THE potentials in THE curricula of this field, strengTHEn THE strengths and eliminate THE weaknesses in THEm. This MODEL, while providing THE conditions for THE realization of entrepreneurship education in academic fields, provides THE context for THE implementation of a local MODEL in THE light of Islamic orders.
