Regularized Yield Surfaces for Crystal Plasticity of Metals
Crystals, 2020 The rate-independent Schmid assumption for a metal crystal results in a yield surface that is faceted with sharp corners. Regularized yield surfaces round off the corners and can be convenient in computational implementations.

High-yield decomposition of surface EMG signals [PDF]
Clinical Neurophysiology, 2010 Automatic decomposition of surface electromyographic (sEMG) signals into their constituent motor unit action potential trains (MUAPTs).A small five-pin sensor provides four channels of sEMG signals that are in turn processed by an enhanced artificial intelligence algorithm evolved from a previous proof-of-principle.

Closed system of coupling effects in generalized thermo-elastoplasticity
International Journal of Applied Mechanics and Engineering, 2016 In this paper, the field equations of the generalized coupled thermoplasticity theory are derived using the postulates of classical thermodynamics of irreversible processses. Using the Legendre transformations two new thermodynamics potentials P and S
