Making effective use of computational grids requires scheduling grid applications onto resources that best match them. Resource-related state (e.g., load, availability, and location), and demand-related state (number and distribution of application resource requests) influences scheduling decision success. The scale of the grid makes collecting and(More)
Grid information dissemination protocols distribute information about the dynamic state of computational resources throughout interconnected wide area grids. Performance metrics for these protocols include the overhead of information packets, and the accuracy of the information at the time it is used to schedule applications. Our previous work advocated(More)
The performance of a new anaesthesia machine was evaluated under low flow anaesthetic technique for 7 months. An assessment under low flow conditions over a definitive period can highlight the drawbacks or advantages of a machine under stringent conditions. The overall performance was satisfactory in the sense that it proved to be an efficient, reliable and(More)
Hydraulic turbines exhibit total load rejection during operation because of high fluctuations in the grid parameters. The generator reaches no-load instantly. Consequently, the turbine runner accelerates to high speed, runaway speed, in seconds. Under common conditions, stable runaway is only reached if after a load rejection, the control and protection(More)
