Abstract: The rapid progress that is achieved in many fields of digital services and applications, especially in the area of audio-visual services and related applications, and the urgent need to communicate and transfer data at high speeds; all this led to the development of Asynchronous Transfer Mode (ATM) protocol. This Protocol is the adopted protocol by the Broadband-Integrated Services Digital Networks (B-ISDN) technology in transferring information through the network.

Abstract:Intelligent recognition techniques, plays a significant role in multidisciplinary problem solving. In particular, various problems like character recognition, iris recognition, fingerprint recognition, signature recognition, and many others can be intelligently solved and automated.The objective of this thesis is to design and build iris recognition system which can be able to recognize the individuals by using artificial neural network. The iris recognition system consists of an automatic segmentation system that is based on the Daugman method.

Abstract: Broadband – Integrated Service Digital Network (B-ISDN) based telecommunication systems support a variety of services. Such as: landline, computer data and video conferencing. This thesis deals with the Quality of Service (QoS) in B-ISDN from the traffic control perspective. The main goal is to allocate bandwidth to network users with bursty traffic characteristics using a dynamic traffic control algorithm called the Bandwidth Contracting Algorithm (BCA). The above algorithm has four types of contracts: Red, Yellow, Short Term Green (STG) and Long Term Green (LTG) contracts.
