Demographic, injury-related, and symptom variables at intake, 3 months, and 12 months postinjury were compared between 50 treated adults with mild traumatic brain injury (MTBI) who were not seeking or receiving financial compensation at any time and 18 who were at each time. Compensation seekers/receivers reported symptom incidence and severity as(More)
We propose a network monitoring, visualization and control system (NMVC) that ensures adequate quality of service to network users while maintaining high network resource utilization. The main components of our system are a network probe, an endsystem probe, software network management agents that provide extensible multi-attribute event filtering for(More)
© The Ecological Society of America www.frontiersinecology.org M threats to biodiversity and ecosystem function from unexpected outbreaks of emerging infectious disease hinges on scientists’ ability to detect and predict disease spread across broad spatial extents in a timely manner (Crowl et al. 2008). The economic cost of collecting sufficient data to(More)

Several adaptation approaches, such as policy-based and reinforcement learning, have been devised to ensure end-to-end quality-of-service (QoS) for enterprise distributed systems in dynamic operating environments. Not all approaches are applicable for distributed real-time and embedded (DRE) systems, however, which have stringent accuracy, timeliness, and(More)
The dynamic and heterogeneous natures of large-scale systems pose fundamental challenges to the design of service composition methods with minimum service disruptions. Improving reliability has long been a topic of extensive research in large-scale systems. Little existing work, however, has considered service deliveries spanning multiple components and(More)
Reacquisition-induced outages continue to increase in importance for advanced systems that employ MIMO antennae, space diversity and adaptive equalizers to mitigate the effects of multipath fading. In addition to the channel model, the fading dynamics plays a key role; hence we provide a novel means of simulating random processes in which we can control the(More)
