Programs express domain-level concepts in their source code. It might be expected that such concepts would have a degree of semantic cohesion. This cohesion ought to manifest itself in the dependence between statements all of which contribute to the computation of the same concept. This paper addresses a set of research questions that capture this informal observation. It presents the results o...

This study after reviewing  construction methods of generators in Archimedean copulas (AC),  proposes several useful lemmas related with generators of AC. Then a new trigonometric Archimedean family will be shown which is based on cotangent function. The generated new family is able to model the low dependence structures.

In this research paper, we explore the philosophical connections between Rough YSystems RYS, mereology and concepts in applied ontology, introduce the concept of contamination-free rough dependence and compare this to possible concepts of probabilistic dependence. The nature of granular rough dependence is also characterized and the reason for breakdown of comparison of rough set models with pr...

this study took an epidemiological approach toward the problem of drug addiction in tehran. the subjects were 300 addicts chosen on the basis of stratified random selection out of the population of 3627 prisoners who were all proven addicts and sentenced to imprisonment by the court in the year 1370. a descriptive survey showed that drug addiction generally, and heroin addiction specifically, i...

In order to show that some of the shortcomings of current 4th grade curriculum in meeting contemporary needs of the society, especially in regard to sustainable development, can be met via teaching, a short course consisting of deliberations on key concepts in sustainable development was designed and carried out on a sample of 58 students of both genders. The pre- and post-test comparisons reve...

As Kumar Jogdeo notes in his 1982 article “Concepts of dependence” in the Encyclopedia of Statistical Sciences, “Dependence relations between random variables is one of the most studied subjects in probability and statistics. The nature of the dependence can take a variety of forms, and unless some specific assumptions are made about the dependence, no meaningful statistical model can be contem...

This paper describes the fundamental concepts of a social reasoning mechanism, designed to be part of an agent's internal model, in a multi-agent systems (MAS) context. It enables an agent to reason about the others using information about their goals, actions, resources and plans. Every agent stores this information in a data structure called external description. We have formally deened and i...
