In this paper; we propose an event-driven simulation based approach to estimate the worst case I R drop and Ldildt inductive noise on the power supply network. The switching noise is modeled as a weighted sum of the switching currents and the rates of change of the switching currents, where the weights are respectively the effective resistance and inductance (on the P/G network) experienced by ...

We study the drivers of geographic variation in U.S. health care utilization, using an empirical strategy that exploits migration of Medicare patients to separate the role of demand and supply factors. Our approach allows us to account for demand differences driven by both observable and unobservable patient characteristics. Within our sample of over-65 Medicare beneficiaries, we find that 40–5...

The sharing of product information plays a central role in coordinating the actions and decisions undertaken by supply chain trading partners. The Electronic Product Code Information Service (EPCIS) is an EPCglobal standard, that aims to enable the sharing of serial-level product related information via the Electronic Product Code (EPC). Central to the EPCIS data model are events that describe ...

This paper presents a discrete-time robust control for electrically driven robot manipulators in the task space. A novel discrete-time model-free control law is proposed by employing an adaptive fuzzy estimator for the compensation of the uncertainty including model uncertainty, external disturbances and discretization error. Parameters of the fuzzy estimator are adapted to minimize the estimat...

T he context of this work is the exploration of unknown polygonal environments with obstacles. Both the outer boundary and the boundaries of obstacles are piecewise linear. The boundaries can be nonconvex. The exploration problem can be motivated by the following application. Imagine that a robot has to explore the interior of a collapsed building, which has crumbled due to an earthquake, to se...

Recent Hurricane Katrina and Rita caused severe economic cessations without expectations in Louisiana State. The natural disasters temporarily produced quantity losses in oil-industry and lead to further economic losses via interindustrial relations. In a sense that oil industry plays a key role to support national economy, estimation of the economic impacts of the disasters should be based on ...
