Ultra-Short-Chain PFASs in the Sources of German Drinking Water: Prevalent, Overlooked, Difficult to Remove, and Unregulated
(Peer reviewed; Journal article, 2022)Per- and polyfluoroalkyl substances (PFASs) have been a focal point of environmental chemistry and chemical regulation in recent years, culminating in a shift from individual PFAS regulation toward a PFAS group regulatory ... -
Ultra-Short-term Photovoltaic Output Power Forecasting using Deep Learning Algorithms
(Peer reviewed; Journal article, 2022)Photovoltaic (PV) is becoming an attractive alternative in Norway in new zero-emission housing projects and in connection with hydropower reservoirs. However, fast-moving clouds result in abrupt changes in PV output power, ... -
Ultra-Wide Band Real Time Location Systems: Practical Implementation and Performance Evaluation
(Chapter, 2017)Several different methods can be used to determine the 3-dimensional position of an object. A common solution is use of Global Navigation Satellite System (GNSS). However, for some operation the specific characteristics ... -
