Service Oriented Architecture (SOA) is becoming the architectural style of choice in many enterprises that adopt the notion of business process architecture. This suggests the need for a systematic and unified approach to generate a service model from a given organizational business process architecture. This paper presents a generic framework called(More)
This study presents an algorithm for MaxFlow problem using "Chemical Reaction Optimization algorithm (CRO)". CRO is a recently established meta-heuristics algorithm for optimization, inspired by the nature of chemical reactions. The main concern is to find the best maximum flow value at which the flow can be shipped from the source node to the sink node in(More)
This paper presents an energy back-propagation algorithm (EBP). Learning and convergence processes of the standard backpropagation algorithm (SBP) are based on the energy function. The energy function is used with the convergence process to extract the nearest image for the unknown tested image. The EBP algorithm shows considerably better performance in(More)
An automatic speech recognition system for the formal Arabic language is needed. The Quran is the most formal spoken book in Arabic, it is spoken all over the world. In this research, an automatic speech recognizer for Quranic based speakerindependent was developed and tested. The system was developed based on the tri-phone Hidden Markov Model and Maximum(More)
Leader election algorithms solve the instability problem in the network which is caused by leader failure .In this paper, we propose a new leader election algorithm in two dimensional torus networks. The algorithm aims to elect one node to be a new leader. The new leader is identified by some characteristics not in the other nodes in the network. When the(More)
An extensive research study was conducted into the trend in educational institutions towards the teaching of sign languages using the Web and the new advances in multimedia computers. A sign language is a visual language and therefore is easier taught by the use of pictures and other multimedia assets. Today's computers allow the average home user to see(More)
Modelling business processes using BPMN has been emerging as the preferred choice for organisations seeking to enact their business processes in service-oriented environments. However, a number of organisations have their business processes modelled using Role Activity Diagramming, RAD. In this research, we introduce a new approach to translating RAD(More)
