We study the different recent improvements on shortest path algorithms. We suggest improvements to the classical path computing algorithms and we implement them using random generated graphs with various sizes. Many attempts ...

Automated software engineering is one of the most important current research problems especially when it comes to requirements analysis and modelling. The main advantage of this automation process is to improve the quality ...

Given a graph G=(V,E,w), where Vand E are finite set of vertices and edges respectively, in a directed weighted graph G with weights denoted by w(e)>0 for each edge e∈ E. Given two vertices <s> and <t>∈ V, P(s,t) is the ...

While current e-learning activities mainly focus on static mode, this paper proposed a simple Active Multimodal Presentation (AMP) application, and evaluated the student achievement in static and active modes. Of the various ...

Given a graph G=(V,E,w), where V and E are finite set of vertices and edges respectively, is a directed weighted graph with weights denoted by w(e)>0 for each edge e ∈E. P(s,t) is the shortest path between the given vertices ...

Current computer technology and various multimedia tools play an increasingly important and effective role in enhancing the learning process. However, current educational multimedia systems still suffer from a major drawback ...

Throughout the requirement engineering, the classification of user requirements has been a major concern of software engineering researchers. In this paper, we first highlighted the contributions of recent authors and ...

Requirement engineering plays a very important role in the software development life cycle. The success or failure of a software project depends prominently on the requirement engineering phase. Requirement documents ...

A sequence diagram is one of UML models that are usually used within the analysis phase in software system development. Since generating such sequence diagrams is performed manually, automated or semi-automated support is ...
