Thermal management becomes a prominent issue in system design for both server systems and embedded systems. A system could fail if the peak temperature exceeds its thermal constraint. This research studies thermal-constrained scheduling for frame-based real-time tasks on a dynamic voltage/speed scaling system. Our objective is to design speed schedulers for real-time tasks by utilizing dynamic voltage/speed...
This paper focuses on improving the overall operations of an interventional radiology department at a community hospital in USA. In the first phase of the improvement process, significant delays, involving waiting time of patients in preparation rooms, delays in their arrival to procedure rooms, and waiting time for the radiologists, were observed. A thorough analysis of the delays led to the second...
We study the communication primitive of broadcasting (one-to-all communication) in known topology radio networks, i.e., where for each primitive the schedule of transmissions is precomputed based on full knowledge about the size and the topology of the network. We show that radio broadcasting can be completed in D+O(logn) time units in planar graphs of size n, diameter D, which improves the currently...
In a military communications environment, multiple communication links could exist between senders and receivers. This feature enhances communication connection reliability and throughput. Since each link may not use the same type of device or transmission method and links' characteristics may not be the same, sometimes, the link availability and link data rate could fluctuate significantly, which...
