An Authentic Ecg Simulator, Paul Michalek Jan 2006

An Authentic Ecg Simulator, Paul Michalek

Electronic Theses and Dissertations

An ECG (electrocardiogram) simulator is an electronic tool that plays an essential role in the testing, design, and development of ECG monitors and other ECG equipment. Principally an ECG simulator provides ECG monitors with an electrical signal that emulates the human heart's electrical signal so that the monitor can be tested for reliability and important diagnostic capabilities. However, the current portable commercially available ECG simulators are lacking in their ability to fully test ECG monitors. Specifically, the portable simulators presently on the market do not produce authentic ECG signals but rather they endeavor to create the ECG signals mathematically. They …

Examining Route Diversion And Multiple Ramp Metering Strategies For Reducing Real-Time Crash Risk On Urban Freeways, Vikash Gayah Jan 2006

Examining Route Diversion And Multiple Ramp Metering Strategies For Reducing Real-Time Crash Risk On Urban Freeways, Vikash Gayah

Electronic Theses and Dissertations

Recent research at the University of Central Florida addressing crashes on Interstate-4 in Orlando, Florida has led to the creation of new statistical models capable of calculating the crash risk on the freeway (Abdel-Aty et al., 2004; 2005, Pande and Abdel-Aty, 2006). These models yield the rear-end and lane-change crash risk along the freeway in real-time by using static information at various locations along the freeway as well as real-time traffic data that is obtained from the roadway. Because these models use the real-time traffic data, they are capable of calculating the respective crash risk values as the traffic flow …

Application Of Swarm Clustering Theory To Optical Self-Organization, Ran Huang Jan 2006

Application Of Swarm Clustering Theory To Optical Self-Organization, Ran Huang

Graduate Theses and Dissertations

Swarm clustering is a biologically inspired technology, which mimics the behavior of an insect colony to solve unsupervised clustering problems. The unique mechanism of swarm clustering is self-organization which can form global patterns without centralized control. In this thesis, swarm-clustering models proposed by Deneubourg and by Lumer and Faieta are studied, implemented and improved by visualizing clustering results using true color representation. In nonlinear optical systems, self-organized patterns are often observed, such as hexagon formation in experiments with KNbO^Fe due to the photorefractive effect. Considering the particle feature of light, we propose to design a self-organizing system in which only …
