abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
the aim of this study was to identify the problems of translating markedness structures from english to persian in order to look closely at what possible difficulties translators may face. it also seeks to probe the strategies applied accordingly by iranian translators in translating them. from three translation of blindness novel, the sentences with marked structures were elicited and also the...
مقدمه: فرکتالها عبارتند از ساختارهای هندسی پیچیده. علم فرکتال که به بررسی این ساختارها می پردازد در سال 1975 ابداع گردید و امروزه نه تنها در علوم مهندسی بلکه در علوم پزشکی نیز جایگاه ویژه ای یافته است. فرکتال ها در تشخیص بیماری های استخوانی و مدل سازی ساختار استخوانها و تحلیل تغییرات ساختار آنها و تحلیل ریتم و ضربان قلب و تشخیص بیماری های قلبی کاربرد دارند. هرچند به نظر می رسد هرکجا که یک بی نظ...
abstract rockfill dams are a type of hydraulic control structures used to protect river bed in cases where a considerable reservoir volume is available behind these structures; it could mitigate the floods and provide a gradual depletion of incoming volume of water so that the discharge passing downstream is decreased. one of the main issues on utilizing rockfill dams is to keep its permeabilit...
rade control structures are used to control bed erosion in steep small rivers mostly in the mountains. Scour downstream of this structure can lead to failure. Over the past years, the effect of different variables on this phenomena have been studied, however the effect of upward seepage which is common due to head difference of the banks water table or water surface level between the upstream a...
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...
