در هر برنامه آموزشی، مهم ترین فاکتور موثر بر موفقیت دانش آموزان کتاب درسی است (مک دونو و شاو 2003). در حقیقت ، کتاب قلب آموزش زبان انگلیسی است( شلدن 1988). به دلیل اهمیت والای کتاب به عنوان عنصر ضروری کلاس های آموزش زبان ، کتب باید به دقت ارزیابی و انتخاب شده تا از هرگونه تاثیر منفی بر دانش آموزان جلوگیری شود( لیتز). این تحقیق با طراحی پرسش نامه ارزیابی کتاب که فرصت ارزیابی معتبر را به اساتید د...

Building a Virtual Shop Model for Steel Fabrication

Steel fabrication is a complex process, which encompasses product uniqueness, a high product mix, and a number of activities involving a variety of equipment and labor disciplines. The steel fabrication industry needs advanced tools and techniques in order to estimate, plan, and control fabrication shops. This paper proposes a system for building virtual fabrication shop models capable of estim...

Seismic Retrofitting of Steel and Composite Building Structures

OPTIMAL PERFORMANCE-BASED SEISMIC DESIGN OF COMPOSITE BUILDING FRAMES WITH RC COLUMNS AND STEEL BEAMS

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

Scenario Building and its Application

Assessing uncertain futures Perceived uncertainties and risks can be considered to be the main motivation behind ‘Futures Thinking’ or ‘Futures Studies’ to assess potential economic, environmental, social or technical developments and their expected consequences on society and environment (or from a systems perspective – feedbacks between the components of complex social-ecological systems, e.g...
