The Response Time Analysis of Digital Broadcasting System

Digital broadcasting system has become a highlight of research on computer application. To respond to the changes of the playbill in the broadcasting system in real time, the response time of the system must be studied. There is scarcely the research on this area currently. The influence factors in the response time are analyzed; the model on the response time of the system service is built; how the influence factors affect the response time of the system service is validated; and four improvement measures are proposed to minimize the response time of system service.

Continuous on-line adaptation of the rotor time constant in FOC induction machine system

Rotor time constant is an important parameter for the indirect lleld oraentateO control of mauc- tion motor. Incorrect rotor tittle constant value will cause the flux observer generating a wrong angu- lar orientation of the rotor field. A new approach serves for rotor time constant on-line adaptation by setting the stator current to be zero for a short period. A smooth eorrector is designed to prevent ab- normal detection result from making adaptation. Impact of zero current duration on detection error and rotor speed is analyzed by experiments.

An extension of contract net protocol with real time constraints

The contract net protocol has developed to specify problem solving communication for nodes in a distributed problem solving. Task distribution is affected by a negotiation process, a discussion carried on between nodes with tasks to be executed and nodes that may be able to execute those tasks. In contract net protocol, once negotiation successes, the task execution is assumed to success. However, in real world, even though a task is awarded to successfully bidding nodes, it may be delayed. Such delay may badly propagate in whole system. Here, we introduce real-time constraints into contract net protocol to manage task execution for avoiding the task's delay, or even though being delayed, the failure cannot propagate to whole system. In this paper, we first present a real-time contract net protocol which is an extension of contract net protocol with real-time constraints for distributed computing. Our proposition extends the basic negotiation protocol to negotiation and controlling execution of task. The controlling process is based on task deadline time we also present an extension of the internode language of contract net protocol specification with real-time constraints Li Qiaoyn, born in Jan. 1965, Lecturer
