While low Dissolved Oxygen (DO) concentrations are not uncommon in the coastal ocean, what is less understood is how the location and size of these low DO regions vary and what impact that variability has on ecosystem health. Therefore, alternative sampling strategies are needed to continuously map these low DO areas in a way that quantifies this variability. This project applies a series of Autonomous...

Tracing current vs. voltage curve is an important part of the documentation of a Photovoltaic (PV) system to comply to the IEC 62446 standard. In order to get the high accuracy, the PV array would be subjected to an unspecified and large number of voltage perturbations often using specialized measuring instruments. In this paper, we explain how to minimize the tracing-time by performing a pre-defined...
Interior permanent magnet synchronous machine drives are widely employed in electric traction systems and various industrial processes. However, prolonged exposure to high temperatures while operating can demagnetize the permanent magnets to the point of irreversible demagnetization. In addition, direct measurements with infrared sensors or contact-types sensors with wireless communication can be...
Research in the area of internet-of-things, cyberphysical-systems, and smart health often employ sensor systems at residences for continuous monitoring. Such research-oriented residential monitoring systems (RRMSs) usually face two major challenges, long-term reliable operation management and validation of system functionality with minimal human effort. Targeting these two challenges, this paper describes...
