COMPUTER AIDED OPTIMIZATION TECHNIQUES BASED ON GENERALIZED CONVEX MAPS

Generalized Kkm Maps on Generalized Convex Spaces

In the present paper, we extend known KKM theorems and matching theorems for generalized KKM maps to G-convex spaces. From these results, we deduce generalized versions of main results of Kassay and Kolumbán [KK] and some others.

Computer Aided Retrodeformation Techniques

A technique whereby a deformed fossil is restored to its original shape is termed retrodeformation. This paper develops four such techniques designed to encompass a broad range of fossil types. The retrodeformation techniques are tested using fossil forms developed by a three dimensional graphics application programming interface, PHIGS and PHIGS PLUS.

study of hash functions based on chaotic maps

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...

Generalized Convex Set-Valued Maps

The aim of this paper is to show that under a mild semicontinuity assumption (the so-called segmentary epi-closedness), the cone-convex (resp. cone-quasiconvex) set-valued maps can be characterized in terms of weak cone-convexity (resp. weak cone-quasiconvexity), i.e. the notions obtained by replacing in the classical definitions the conditions of type ”for all x, y in the domain and for all t ...
