  In this study, We propose a fuzzy neural system containing inferred rules which are modelled separately by a three layer perceptron neural network giving the conclusion part according to the premise of the rule. Such a system is applied to different morphology words for Arabic vowels recognition as a two-dimensional fuzzy implication presented in the form of linguistic features values. The system has been implemented on a real-time mini-computer and is now operational, the results concerning a multi-speaker corpus of continuous speech are also promising.

  In this study, a media access control protocol is proposed for multimedia traffic in slotted CDMA. The channel resource is proposed into three compartments: video, voice and data. Video packet occupies a whole frame whereas each voice and data packet only occupies a slot in the frame. The concepts of dynamic boundary is adopted in both code and time domains to meet the different requirements for video, voice and data traffic. Data traffic is allowed to use any idle slots of the voice compartment and voice traffic is permitted to use unused video slots but video traffic is not permitted to use any unused slots. An efficient channel borrowing strategy is introduced to both schemes to achieve better Quality of Service (QoS) in a CDMA-based video/voice/data integrated system. The numerical models are developed to evaluate and compare their performances. This model uses the Markov analysis to calculate the video and voice blocking probabilities. The results indicate that an improved performance can be achieved by introducing the dynamic boundary scheme and the dynamic assignment policy results in a performance close to the optimal value.
