1. Reliability and Availability Improvement in Economic Data Grid Environment Based On Clustering Approach

Ali Abbasi; Amir Masoud Rahmani; Esmaeil Zeinali Khasraghi

Volume 1, Issue 4 , Autumn 2015, Pages 1-14

Abstract
  Abstract - One of the important problems in grid environments is data replication in grid sites. Reliability and availability of data replication in some cases is considered low. To separate sites with high reliability and high availability of sites with low availability and low reliability, clustering ...  Read More

Behrouz Sadeghi; Vahid Khatibi Bardsiri; Monireh Esfandiari; Farzad Hosseinzadeh

Volume 1, Issue 4 , Autumn 2015, Pages 15-24

Abstract
  One of the most important and valuable goal of software development life cycle is software cost estimation or SCE. During the recent years, SCE has attracted the attention of researchers due to huge amount of software project requests. There have been proposed so many models using heuristic and meta-heuristic ...  Read More

5. Mining Frequent Patterns in Uncertain and Relational Data Streams using the Landmark Windows

fatemeh Abdi; Aliasghar Safaei

Volume 1, Issue 4 , Autumn 2015, Pages 43-52

Abstract
  Todays, in many modern applications, we search for frequent and repeating patterns in the analyzed data sets. In this search, we look for patterns that frequently appear in data set and mark them as frequent patterns to enable users to make decisions based on these discoveries. Most algorithms presented ...  Read More

6. A hybrid meta-heuristic algorithm based on ABC and Firefly algorithms

azita yousefi; bita amirshahi

Volume 1, Issue 4 , Autumn 2015, Pages 53-58

Abstract
  Abstract— In this paper we have tried to develop an altered version of the artificial bee colony algorithm which is inspired from and combined with the meta-heuristic algorithm of firefly. In this method, we have tried to change the main equation of searching within the original ABC algorithm. ...  Read More
