Graceful Performance Modulation for Power-Neutral Transient Computing Systems

Power Systems Transient Stability - A Grand Computing Challenge

Real-time or faster-than-real-time power system transient stability simulations will have signi cant impact on the future design and operations of both individual electrical utility companies and large interconnected power systems. Su ciently fast transient stability simulation implementations may signi cantly improve power system reliability which, in turn, will positively a ect electrical uti...

Adaptive Power and Performance Management of Computing Systems

Power-aware computing systems

This paper summarizes the objectives and structure of a seminar with the same title, held from April 3rd to April 8th 2005 at Schloss Dagstuhl, Germany.

Power Supply and Current Modulation Circuits for Semiconductor Lasers

Design and construction of a stable current supply with protection circuits are described. The reported circuit provides a high-stable and high-level current variable from 0.5-1.2 A with the protect ion circuits to prevent over load current, voltage and off-range temperature operation. A detailed analysis of the circuit parameters is given and the time behaviors of the load voltage/current and ...

Automatic Graceful Degradation for Distributed Embedded Systems

It has long been a tenet of the fault-tolerance research community that fault– tolerance is possible by exploiting resource redundancy in order to achieve the mission result. Hardware designers, for instance, rely upon various forms of redundant hardware to ensure the availability of at least one system that can produce correct responses. Strangely, one source of redundancy has not been compreh...
