Caffeine Model Identification For Vigilance Performance Prediction, Chun-Hui Huang
Caffeine Model Identification For Vigilance Performance Prediction, Chun-Hui Huang
Mechanical & Aerospace Engineering Theses & Dissertations
The pharmacodynamics and pharmacokinetics of caffeine have been well characterized. In this study, a caffeine dynamic model is developed to describe its pharmacodynamic effects on vigilance performance. Validated biomathematical models developed to address both individual and group fatigue and alertness in a non-laboratory setting represent a tremendous commercial opportunity. First, a test data set with caffeine effects isolated from circadian and homeostatic effects is created. Then a modeling approach for input and output effects is developed and different model structures for the caffeine effects are considered. Observer/Kalman filter Identification (OKID) algorithm is proposed and developed to identify the caffeine model …
Real-Time Ultrasound Simulation For Medical Training And Standardized Patient Assessment, Bo Sun
Real-Time Ultrasound Simulation For Medical Training And Standardized Patient Assessment, Bo Sun
Computational Modeling & Simulation Engineering Theses & Dissertations
With the increasing role played by ultrasound in clinical diagnostics, ultrasound training in medical education has become more and more important. The clinical routine for ultrasound training is on real patients; therefore monitored and guided examinations involving medical students are quite time-constrained. Furthermore, standardized patients (SPs), who are increasingly used in medical school for teaching and assessing medical students, need to be augmented. These SPs are typically healthy individuals who can not accurately portray the variety of abnormalities that are needed for training especially when medical examinations involve instrument interactions. To augment SPs in a realistically effective way and also …
