1. Improving the Operation of Text Categorization Systems with Selecting Proper Features Based on PSO-LA

Mozhgan Rahimirad; Mohammad Mosleh; Amir Masoud Rahmani

Volume 1, Issue 2 , Spring 2015, Pages 1-8

Abstract
  With the explosive growth in amount of information, it is highly required to utilize tools and methods in order to search, filter and manage resources. One of the major problems in text classification relates to the high dimensional feature spaces. Therefore, the main goal of text classification is to ...  Read More

2. A Genetic Programming-based trust model for P2P Networks

Mahdi Sattarivand

Volume 1, Issue 2 , Spring 2015, Pages 9-14

Abstract
  Abstract— Peer-to-Peer ( P2P ) systems have been the center of attention in recent years due to their advantage . Since each node in such networks can act both as a service provider and as a client , they are subject to different attacks . Therefore it is vital to manage confidence for these vulnerable ...  Read More

3. Online multiple people tracking-by-detection in crowded scenes

Sahar Rahmatian; Reza Safabakhsh

Volume 1, Issue 2 , Spring 2015, Pages 15-22

Abstract
  Multiple people detection and tracking is a challenging task in real-world crowded scenes. In this paper, we have presented an online multiple people tracking-by-detection approach with a single camera. We have detected objects with deformable part models and a visual background extractor. In the tracking ...  Read More

5. Adaptive Rule-Base Influence Function Mechanism for Cultural Algorithm

Vahid Seydi Ghomsheh; Mohamad Teshnehlab; Mehdi Aliyari Shoordeli

Volume 1, Issue 2 , Spring 2015, Pages 29-38

Abstract
  This study proposes a modified version of cultural algorithms (CAs) which benefits from rule-based system for influence function. This rule-based system selects and applies the suitable knowledge source according to the distribution of the solutions. This is important to use appropriate influence function ...  Read More

6. Topology Control in Wireless Sensor Network using Fuzzy Logic

Samaneh Nazari Dastjerdi; Hamid Haj Seyyad Javadi

Volume 1, Issue 2 , Spring 2015, Pages 39-44

Abstract
  Network sensors consist of sensor nodes in which every node covers a limited area. The most common use ofthese networks is in unreachable fields.Sink is a node that collects data from other nodes.One of the main challenges in these networks is the limitation of nodes battery (power supply). Therefore, ...  Read More
