An important goal in rehabilitation engineering is to develop technology that allows individuals with severe motor impairment to practice arm movement without continuous supervision from a rehabilitation therapist. This paper describes the development of such a system, called Therapy WREX or ("T-WREX"). The system consists of an orthosis that assists in arm(More)
Zombies are a popular figure in pop culture/entertainment and they are usually portrayed as being brought about through an outbreak or epidemic. Consequently, we model a zombie attack, using biological assumptions based on popular zombie movies. We introduce a basic model for zombie infection, determine equilibria and their stability, and illustrate the(More)
Governments have agreed to expand the global protected area network from 13% to 17% of the world's land surface by 2020 (Aichi target 11) and to prevent the further loss of known threatened species (Aichi target 12). These targets are interdependent, as protected areas can stem biodiversity loss when strategically located and effectively managed. However,(More)
Rip-up and reroute strategies can be applied following use of conventional wiring algorithms to calculate paths for residual connections failed by preceding techniques. The removal of blocking wire to allow new path runs inevitably introduces new (reroute) wiring requirements. In this paper we address the performance implications of various rates of success(More)
In early detection of disease, combinations of biomarkers promise improved discrimination over diagnostic tests based on single markers. An example of this is in prostate cancer screening, where additional markers have been sought to improve the specificity of the conventional Prostate-Specific Antigen (PSA) test. A marker of particular interest is the(More)
Parallel processing is being recognized as a practical way to achieve very high performance in logic simulation of large designs. This tutorial summarizes many of the basic methods employed, and estimates attainable throughput. Next, data structuring and processing factors are explored as they impact parallel simulation. Experience indicates that support(More)
Architectural simulation of complex systems is usually constrained by available computational resources. Recently, several commercial parallel processing systems have appeared with price-performance levels that make very intense simulations affordable. In this paper, we briefly review architectural simulation technology, then describe the approach used to(More)
The ideal conservation planning approach would enable decision-makers to use population viability analysis to assess the effects of management strategies and threats on all species at the landscape level. However, the lack of high-quality data derived from long-term studies, and uncertainty in model parameters and/or structure, often limit the use of(More)
The financial cost of biodiversity conservation varies widely around the world and such costs should be considered when identifying countries to best focus conservation investments. Previous global prioritizations have been based on global models for protected area management costs, but this metric may be related to other factors that negatively influence(More)
