Pre-Pressure Optimization for Ultrasonic Motors Based on Multi-Sensor Fusion

Sensors, 2020
This paper investigates the pre-pressure’s influence on the key performance of a traveling wave ultrasonic motor (TRUM) using simulations and experimental tests. An analytical model accompanied with power dissipation is built, and an electric cylinder is

Magnetic Scaling Laws for the Atmospheres of Hot Giant Exoplanets

, 2011
We present scaling laws for advection, radiation, magnetic drag and ohmic dissipation in the atmospheres of hot giant exoplanets. In the limit of weak thermal ionization, ohmic dissipation increases with the planetary equilibrium temperature (T_eq ...

A High-Performance Multiply-Accumulate Unit by Integrating Additions and Accumulations Into Partial Product Reduction Process

IEEE Access, 2020
In this paper, we propose a low-power high-speed pipeline multiply-accumulate (MAC) architecture. In a conventional MAC, carry propagations of additions (including additions in multiplications and additions in accumulations) often lead to large power ...
