this paper addresses a multi-criteria decision based methodology to develop a road network cost function for route finding analysis in a geographic information system (gis). over the years, several studies relating to route planning process in gis and intelligent transportation systems (its) have been conducted, most of which rely on the use of one-dimensional variables like distance or time as...

abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

‎In this essay we introduce and study the notion of dimension for observers via Caratheodory structures and relative probability measures‎. ‎We show that the dimension as a three variables function is an increasing function on observers‎, ‎and decreasing function on the cuts of an observer‎. ‎We find observers with arbitrary non-negative dimensions‎. ‎We show that Caratheodory dimension for obs...

Introducing more types of integrals will provide more choices todeal with various types of objectives and components in real problems. Firstly,in this paper, a (T) fuzzy integral, in which the integrand, the measure andthe integration result are all multi-valued, is presented with the introductionof T-norm and T-conorm. Then, some classical results of the integral areobtained based on the prope...

It is conventional to use multi-dimensional indexing structures to accelerate search operations in content-based image retrieval systems. Many efforts have been done in order to develop multi-dimensional indexing structures so far. In most practical applications of image retrieval, high-dimensional feature vectors are required, but current multi-dimensional indexing structures lose their effici...

به منظور تخمین زمانی- مکانی مقدار بارش ماهیانه، با توجه به پیچیدگی پدیده و در دسترس نبودن اطلاعات فیزیکی کافی و عدم اطلاع دقیق از روابط و معادلات ریاضی حاکم بر مسئله، معمولاً به سراغ ارائ? مدلهای جعبه سیاه، که مستقل از پارامترهای فیزیکی موثر بر پدیده و معادلات حاکم بین آنها می باشد، باید رفت. در این پایان نامه مدلی ترکیبی و جعبه سیاه تحت عنوان ann-rbf به منظور تخمین زمانی- مکانی مقدار بارش ماهی...
