investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
fuzzy logic has been developed over the past three decades into a widely applied techinque in classification and control engineering. today fuzzy logic control is one of the most important applications of fuzzy set theory and specially fuzzy logic. there are two general approachs for using of fuzzy control, software and hardware. integrated circuits as a solution for hardware realization are us...
abstract the decisions and personal preferences of the designer are vital for all aspects and stages of the design. to elaborate, the designer has the central role in creation, development, detailing and construction of the built forms. also, the scientific/engineering evaluations of the design models are carried out under the directions and decisions of the designer. the paper explores the con...
The final quality and cost of a manufactured product are determined to a large extent by the engineering design of the product and its production process through activities of off-line quality control methods, namely, System Design, Parameter Design and Tolerance Design. However, in the context of most non-industrialized countries, the off-line quality activities of product design and system de...
با توجه به استفاده روز افزون از تحلیل های غیر خطی در آیین نامه های معتبر همچون atc40 و fema256 و fema360 در برآورد دقیق لرزه ای ساختمان ها در تعیین سطح عملکرد و روی آوردن اکثر آیین نامه ها به طراحی بر اساس عملکرد performane base design ، به این نوع تحلیل ها برای بهینه سازی و پیش بینی دقیق رفتار ساختمان در برابر زلزله مورد نیاز احساس می شود.
در این پروژه تولید روغن زیستی توسط فرآیند مایعسازی هیدروترمال از گونه های ریزجلبک کلرلا ولگاریس، اسپیرولینا پالاتنسیس و دونالیلا سالینا مطالعه و با بررسی بازده تولید روغن زیستی در شرایط مختلف و بر مبنای پارامترهای عملیاتی، نقاط بهینه بازده برای هر کدام از ریزجلبکها بدست آمده است.بهینه سازی فرآیند استخراج توسط طراحی آزمایش با نرم افزار design expert 7.0.0 و روش سطح پاسخ (طرح ترکیب مرکزی) انجام گ...
مبحث طراحی ابعاد بسیار وسیعی دارد که به طور عمده در سه حیطه طراحی هنری ، طراحی صنعتی و طراحی سنتی طبقه بدی شده است . در این تحقیق به بررسی طراحی هنری مدرن و پست مدرن علی الخصوص در عرصه نقاشی پرداخته می شود .طراحی (design)در مفهوم معاصر ، برنامه ریزی خلاقی است در پاسخ به نیازی مشخص .در اینجا تاکید بر طراحی به مفهوم خاص drawing می باشد .
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
in the past, medical device design always was performed with medical engineers, technicians and physicians in all design stages and the industrial design role was pale in this field. today the industrial design responsibilities in designing of these devices are considered increasingly. the industrial design role in medical device design was investigated in two fields. first are aesthetic and it...
