This paper describes design and computer simulation of a new architecture of a node active network element, based on artificial neural network technology with the support of priority processing for different connection types. As an example of a network element was selected switching area. This network element with optimized switching ar ea is able to transfer large data quantity with minimum de...

Two Parallel Interference Cancellation (PIC) schemes, based on the Probabilistic Data Association (PDA) approach are evaluated with respect to the allowable load. The N-dimensional PDA detector achieves an acceptable load that is more than three times higher than that of the one-dimensional detector. An improvement of these PIC schemes is proposed by replacing the a priori probabilities in ever...

Computer-mediated communication environments such as personal websites enable users to use multimedia to construct their self-identities. How these multimedia elements in the cyberspace such as audios influence interpersonal impressions is somewhat unclear in the literature. Based on Brunswik’s lens model, this research aims to examine the impact of audio information on impression formation by ...

The world wide web (WWW) is not anymore just an information retrieval system [1] but rather an interactive communication medium. Within the last decade online social networks have evolved and constantly increased in popularity. The currently most used online social network services, according to their estimated monthly active users1, are Facebook (1.27 billion, facebook.com), Google Plus (541mi...

Background and Objectives: Considering the importance of adolescents' health and that the first step in designing a comprehensive health plan is to assess the needs of the target group, this study was conducted to determine the health needs of adolescents in Aran-Bidgol City, Iran. Methods: This Cross-sectional-analytical study was performed on 497 students (265 girls and 232 boys) aged 12-18...

As mobile data traffic increases, and the number of services provided by the mobile network increases, service load flows as well, which requires changing in the principles, models, and strategies for media transmission streams serving to guarantee the given nature of giving a wide scope of services in Flexible and cost-effective. Right now, the fundamental question remains what number of netwo...

Social functions are natural consequences of human societies. Before communication technologies, social functions tend to evolve within cultural boundaries, such as location and families. Communication technologies, from mountain top signaling to Voiceover-IP, have broken those boundaries more or less and enabled multi-culture social functions. Empowered by low-cost, high-power personal computi...
