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...

فرض کنیم g یک گروه آبلی دلخواه و t زیرگروه تابدار ازg باشد. اگر a نسبت به خاصیت مجزا بودن از t ماکسیمال باشد آنگاه a یک زیرگروه t-بلند از g خوانده می شود. در این پایان نامه ابتدا نشان می دهیم که زیرگروه t-بلند l از گروه آبلی g از رتبه بی تاب یک وجود دارد بطوریکه برای هر زیرگروه t-بلند a از g داشته باشیم (type (l) ≤ type (a. در مرحله ی بعد گروههای آبلی از رتبه بی تاب یک که همه ی زیرگروههای t-بل...

the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...

‎in this article‎, ‎we have focused one some basic and productive information about the properties of spectrum and singular values related to compact operators which are ideals in a c*-algebra of bounded operators‎. ‎considering a two-sided connection between the family of symmetric gauge functions on sequence of singular values of compact operators and symmetric norms on finite dimensional ope...

in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...

among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...

توده گرانیتوئیدی ارلان با انواع مرتبط با محیط های تکتونیکی پس از برخورد و جایگاههای ژئودینامیکی درون صفحه ای سازگار است. این توده گرانیتوئیدی جزء انواع a-type بوده و به زیرگروه a2-type تعلق داشته و در محیط های تکتونیکی پس از برخورد و از ذوب پوسته لیتوسفر زیر قاره ای و در رژیم زمین ساختی کششی تکوین یافته است. تشکیل این توده مرتبط با فازهای کششی بعد از خاتمه فاز فشارشی آسینتیک می باشد.

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...

this study investigated the effects of planning on second-language written production with regard to task type. the participants were 75 iranian learners of english as a foreign language attending a private foreign language institution. they were asked to complete two different types of writing tasks (expository writing task and argumentative writing task) in different planned conditions (indiv...
