Fast Evaluation of Demagnetizing Field in Three Dimensional Micromagnetics using Multipole Approximation
Computational micromagnetics in three dimensions is of increasing interest with the development of magnetostrictivesensors and actuators. <p>In solving the Landau-Lifshitz-Gilbert (LLG) equation, the governing equation of ...
Control of Smart Actuators: A Viscosity Solutions Approach
Hysteresis in smart materials hinders their wider applicability in actuators. In this report we investigate control of smart actuators through the example of controlling a commercially available magnetostrictive actuator. ...
Tool Wear Estimation from Acoustic Emissions: A Model Incorporating Wear Rate
Almost all prior work on modeling the dependence of acoustic emissions on tool wear have concentrated on the effect of wear-level on the sound. We give justification for including the wear-rate information contained in the ...
Biologically-Inspired Acoustic Wear Analysis
We report on a novel method of acoustic wear analysis using spectral classification based on a model of mammalian audition. This approach uses biologically-inspired pre-processing filters that give a multi- resolution ...
