Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether ...

We present an efficient nonconformal-mesh discontinuous Galerkin (DG) method for elastic wave propagation in viscous media. To include the attenuation and dispersion due to the quality factor in time ...

The standing wave ultrasonic motor (SWUSM) utilizes two resonant modes to enhance stator motion. The less the frequency separation between two resonance modes, the faster the speed of standing wave ...
