Applications of Physics-Informed Neural Networks in Power Systems - A Review

IEEE Transactions on Power Systems, 2023
The advances of deep learning (DL) techniques bring new opportunities to numerous intractable tasks in power systems (PSs). Nevertheless, the extension of the application of DL in the domain of PSs has encountered challenges, e.g., high requirement for ...

Dual-energy CT based mass density and relative stopping power estimation for proton therapy using physics-informed deep learning

Physics in Medicine and Biology, 2022
Proton therapy requires accurate dose calculation for treatment planning to ensure the conformal doses are precisely delivered to the targets. The conversion of CT numbers to material properties is a significant source of uncertainty for dose calculation.

On the physical meaning of the power factor in acoustics

The Journal of the Acoustical Society of America, 2012
Following recent advancements in the study of time-averaged properties of energy propagation in linear acoustic fields, the well established concept of power factor known from the electric AC circuits analysis, is here extended to acoustics. This allows our outline of a complete acousto-electro-mechanic analogy, where the fundamental physical concept ...

Reliability of Power in Physical Performance Tests

Sports Medicine, 2001
The reliability of power in tests of physical performance affects the precision of assessment of athletes, patients, clients and study participants. In this meta-analytic review we identify the most reliable measures of power and the factors affecting reliability. Our measures of reliability were the typical (standard) error of measurement expressed as

Physics of semiconductor power devices [PDF]

Reports on Progress in Physics, 1982
Semiconductor power devices are designed to rapidly switch or amplify high currents, to support high voltages, and to control electric power. Because of these requirements, their topographies and structures are different from those of small-signal devices. Specific designs are the result of the understanding of the physics of p-n junction HV breakdown,

USB-powered physics experiments

The Physics Teacher, 2020
Physics experiments powered by a universal serial bus (USB) connection are becoming increasingly common. With teachers going through so many batteries each year, USB-powered physics provides an economical and environmentally friendly alternative. In this article, the authors discuss several ways that USB power can provide a convenient way to do physics
