High Currents, When Hot

Venting of Turbidity Currents: When to Act?

During floods, sediments are transported from watersheds into reservoirs, slowly decreasing water volumes and this leading to economic losses. Thus, in the long term, sedimentation endangers reservoirs’ sustainability. Sediments can also block low-level hydraulic structures such as bottom outlets and powerhouse intakes and cause abrasion of gates and turbines. Additionally, the trapped sediment...

Preventing Neutral Circulating Currents when Paralleling Generators

High Frequency Currents

ment by the high frequency electrical currents is of very great value, and it is in the hope " that it may in some way help to bring before the notice of medical men the undoubted therapeutical value of high frequency currents in certain pathological conditions," that the author submits this book to the medical profession. The first part of the book is devoted to a description of the production...

Excess Hot-Carrier Currents in SO1 MOSFETs and Its Implications

This work demonstrates that excess hot-carrier currents in SO1 MOSFETs are caused by self-heating. Self-heating-free Ism data should be used for dynamic lifetime extrapolation due to long thermal time constant. The underlying mechanism, increased impact ionization with temperature at low drain bias, is studied experimentally from the angle of thermal activation energy. Our study indicates that ...

Hot Stars with Hot Jupiters Have High Obliquities

We show that stars with transiting planets for which the stellar obliquity is large are preferentially hot (Teff > 6250 K). This could explain why small obliquities were observed in the earliest measurements, which focused on relatively cool stars drawn from Doppler surveys, as opposed to hotter stars that emerged later from transit surveys. The observed trend could be due to differences in pla...
