Engineers and designers commonly use electric motors to power hydraulic pumps. In some cases, the motor and pump are set up in a direct drive configuration. In others, they are connected using an ...

Abstract: As is well known electromechanical coupling coefficient is extraordinarily important parameter, which defines the measure of acoustic wave piezoactivity and allows comparison of various ...

Astrophysical tests of the stability—or not—of fundamental couplings (e.g., can the numerical value ∼1/137 of the fine-structure constant α = e2/ℏc vary with astronomical time?) are a very active area ...

The term “market coupling” is back in vogue with the Central Electricity Regulatory Commission (CERC) issuing a suo motu order directing Grid Controller of India Limited (Grid-India) to implement it ...

Despite coupling fractions being extensively used in the interseismic period, the coexistence of locking and creeping mechanisms and the correlation between the coupling fraction and locking depth ...

As the confirmation hearing for Judge Ketanji Brown Jackson went into hour 13, Sen. Marsha Blackburn asked the Supreme Court nominee on Tuesday to define the word “woman.” “I can’t — ” Jackson replied ...

Senator Marsha Blackburn tried to get Judge Ketanji Brown Jackson to give a definition of “woman,” as part of a diatribe against transgender rights. By Jonathan Weisman Republicans have spent hours ...
