[ 1 ] - Transforming Fuzzy State Diagram to Fuzzy Petri net

UML is known as one of the most common methods in software engineering. Since this language is semi-formal, many researches and efforts have been performed to transform this language into formal methods including Petri nets. Thus, the operation of verification and validation of the qualitative and nonfunctional parameters could be achieved with more ability. Since the majority of the real world...

[ 2 ] - Deterministic Measurement of Reliability and Performance Using Explicit Colored Petri Net in Business Process Execution Language and Eflow

Today there are many techniques for web service compositions. Evaluation of quality parameters has great impact on evaluation of final product. BPEL is one of those techniques that several researches have been done on its evaluation. However, there are few researches on evaluation of QoS in eflow. This research tries to evaluate performance and reliability of eflow and BPEL through mapping them...

[ 3 ] - A New Heuristic Algorithm for Drawing Binary Trees within Arbitrary Polygons Based on Center of Gravity

Graphs have enormous usage in software engineering, network and electrical engineering. In fact graphs drawing is a geometrically representation of information. Among graphs, trees are concentrated because of their ability in hierarchical extension as well as processing VLSI circuit. Many algorithms have been proposed for drawing binary trees within polygons. However these algorithms generate b...

[ 5 ] - A Technique for Improving Web Mining using Enhanced Genetic Algorithm

World Wide Web is growing at a very fast pace and makes a lot of information available to the public. Search engines used conventional methods to retrieve information on the Web; however, the search results of these engines are still able to be refined and their accuracy is not high enough. One of the methods for web mining is evolutionary algorithms which search according to the user interests...
