STATISTICAL MODELS AND INFERENCE FOR LI-ION BATTERY PROGNOSTICS
Developing prognostics and health management methods for Li-ion batteries has received increasing attention in recent years. This thesis proposes three statistical models and inference for the Li-ion battery prognostics based on the easy to measure operational profiles. The three models include a …

A Study on Remaining Useful Life Prediction for Prognostic Applications
<p> <p>We consider the prediction algorithm and performance evaluation for prognostics and health management (PHM) problems, especially the prediction of remaining useful life (RUL) for the milling machine cutter and lithium ‐ </p> </p> <p> <p>ion battery. We modeled battery as a voltage source and …

Ultra-wideband Radar Detection of Breathing Rate: A Comparative Evaluation
… work explores the use of a commodity ultra-wideband (UWB) radar based device to detect breathing rate for health monitoring applications. Health monitoring devices observe physiological signals to detect medical conditions. We focus on capturing the small mechanical movements caused by breathing. …
