Focus in Searching Core–Periphery Structures

Searching Ordered Structures

Suppose distinct real numbers are assigned to the elements of a finite partially ordered set P in an order preserving manner. The problem of determining the fewest numbers of comparisons required to locate a given number x in P is investigated. Some general bounds are provided for the problem and analyzed in detail for the case that P is a product of chains and that P is a rooted forest. t19x5 ...

Searching for Optimal Coalition Structures

Coalition formation has been a very active area of research in multiagent systems. Most of this research has concentrated on decentralized procedures that allow selfinterested agents to negotiate the formation of coalitions and division of coalition payoffs. A different line of research has addressed the problem of finding the optimal division of agents into coalitions such that the sum total o...

focus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes

چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...

Searching Model Structures Based on Marginal Model Structures

Searching for the Native Structures of Proteins

Protein structure prediction is one of the major challenges in bioinformatics today. Throughout the past five decades many different algorithmic approaches have been attempted, and while progress has been made the problem remains unsolvable even for many small proteins. While the general objective is to predict the three-dimensional structure from primary sequence, our current knowledge and com...
