considering the network structure is one of the new approaches in studying stochastic pert networks (spn). in this paper, planar networks are studied as a special class of networks. two structural reducible mechanisms titled arc contraction and deletion are developed to convert any planar network to a series-parallel network structure. in series-parallel spn, the completion time distribution fu...
Introduction: Internet social networks as a place for the different segments of society, especially the youth have become. The aim of this study was survey of social networking usage and its relationship with the study status of students of Ilam universities 2015. Material and Methods: In this cross-sectional study, 400 students of Ilam universities were selected by simple random sampling me...
In recent years, the social networks analysis gains great deal of attention. Social networks have various applications in different areas namely predicting disease epidemic, search engines and viral advertisements. A key property of social networks is that interpersonal relationships can influence the decisions that they make. Finding the most influential nodes is important in social networks b...

The current study aimed at investigating the negative consequences of the use of social networks at the workplace from the viewpoint of the employees of the sports and youth departments. Methods. The current descriptive survey was conducted on Golesta...
Background: This study aimed to evaluated trends for iron and manganese concentrations in wells, reservoirs, and water distribution networks in Qom city during the summer of 2012. Methods: This was a cross-sectional study. The studied scopes consisted of groundwater (60 wells), reservoirs (10 tanks), and water distribution network (33 points). One sample was taken from each source monthly. Stat...
Policy networks consist of state and social actors whose interactions lead to the formulation and/or implementation of policies. One of the characteristics of networks is that power is usually distributed and lies in the relationships among actors. Therefore, network accountability can be problematic. The purpose of this study is to form a theoretical framework for accountability in public poli...
Objectives: Our research seeks to examine the correlation between the presence of physical medicine and rehabilitation journals in social networks and the SJR impact factor. Methods: We carried out a correlation study. For the research, we took into account all physical medicine and rehabilitation journals included in the SCImago Journal Rank. The number of followers on Twitter, Facebook, YouT...

Background and Aim: The aim was to investigate the effect of membership in social networks and mental rumination on cognitive flexibility of female law students at Islamic Azad University of Ghaemshahr. Method: The research method was correlational. Sample of 70 law students randomly selected by Krejcie Morgan. Instruments used were: 1. A questionnaire to study the effects of membership in ...
Stability of synchronous state is a fundamental problem in synchronization. We study Matrix Measure as an approach for investigating of stability of synchronous states of chaotic maps on complex networks. Matrix Measure is a measure which depends on network structure. Using this measure and comparing with synchronization threshold which depends on the function of the map, show us how the synchr...
