Dependability Enhancing Mechanisms For Integrated Clinical Environments, Wenbing Zhao, Mary Q. Yang Oct 2017

Dependability Enhancing Mechanisms For Integrated Clinical Environments, Wenbing Zhao, Mary Q. Yang

Electrical and Computer Engineering Faculty Publications

In this article, we present a set of lightweight mechanisms to enhance the dependability of a safety-critical real-time distributed system referred to as an integrated clinical environment (ICE). In an ICE, medical devices are interconnected and work together with the help of a supervisory computer system to enhance patient safety during clinical operations. Inevitably, there are strong dependability requirements on the ICE. We introduce a set of mechanisms that essentially make the supervisor component a trusted computing base, which can withstand common hardware failures and malicious attacks. The mechanisms rely on the replication of the supervisor component and employ only …


Design Optimization Of A High Power Led Matrix Luminaire, Jose Luiz F. Barbosa, Daniel J. Simon, Wesley P. Calixto May 2017

Design Optimization Of A High Power Led Matrix Luminaire, Jose Luiz F. Barbosa, Daniel J. Simon, Wesley P. Calixto

Electrical and Computer Engineering Faculty Publications

This work presents a methodology for optimizing the layout and geometry of an m x n high power (HP) light emitting diode (LED) luminaire. Two simulators are used to analyze an LED luminaire model. The first simulator uses the finite element method (FEM) to analyze the thermal dissipation, and the second simulator uses the ray tracing method for lighting analysis. The thermal and lighting analysis of the luminaire model is validated with an error of less than 10%. The goal of the optimization process is to find a solution that satisfies both thermal dissipation and light efficiency. The optimization goal …
