The last four decades have seen the development of several mathematical models describing different aspects of blood glucose regulation, mainly the dynamics of glucose metabolism and the insulin action on glucose production and utilization. One of these models, developed by Ghosh and Maka involves representation of the glucose-insulin dynamics by a (piecewise affine) PWA model. The PWA modeling allows...
External stressors like parasites cause alteration in the metabolic pathways of the host. Monitoring the small molecular weight metabolites in the tissue or biofluid offer a convenient approach to understand these alterations. In this paper, we report a urine 1H NMR based metabonomic study to understand the alterations in the human host during the infection of the malarial parasite Plasmodium vivax...
This paper describes the load flow simulation studies of the Western grid of Bangladesh Power System using PSAT, a free and open-source software and compares the results with those from PowerWorld, a well-accepted and commercial software. The studied power system contains 41 buses and 82 interconnecting lines. To ground the basis of comparison, both of the applications were run in the same simulation...
In the event of disasters such as hurricanes, earthquakes and terrorism, emergency relief supplies need be distributed to disaster victims in timely manner to protect the health and lives of the victims. We develop a modeling framework for disaster response where the supply chain of relief supplies and distribution operations are simulated, and analytics for the optimal transportation of relief supplies...
Particle Swarm Optimization (PSO) is arguably one of the most popular nature- inspired algorithms for real parameter optimization at present. The existing theoretical research on PSO is mostly based on the gbest (global best) particle topology, which usually is susceptible to false or premature convergence over multi-modal fitness landscapes. The present standard PSO (SPSO 2007) uses an lbest (local...
There is a need for rigorous analysis techniques that developers can use to uncover security policy violations in their UML designs. There are a few UML analysis tools that can be used for this purpose, but they either rely on theorem-proving mechanisms that require sophisticated mathematical skill to use effectively, or they are based on model-checking techniques that require a ldquoclosed-worldrdquo...
Manufacturing and operation-induced variations have emerged as a critical challenge in designing integrated circuits (ICs) under the nanometer technology regime. Most work on addressing variations has focused on device, circuit, and logic-level solutions. As the magnitude of parameter variations increases with technology scaling, these techniques are not sufficient to address the negative impact that...
