Muscle fatigue during electrical stimulation onsets early and is comparatively more substantial than during volitional contractions, hindering successful application of functional and therapeutic neuromuscular electrical stimulation (NMES). One of the avoidable causes of muscle fatigue can be attributed to the overstimulation during NMES. In this paper, a NMES controller is developed to minimize a...
Neuromuscular Electrical Stimulation (NMES) (also described as functional electrical stimulation (FES) in some scenarios) is a prescribed treatment for various neuromuscular disorders where an electrical stimulus is provided to elicit a muscle contraction. Barriers to the development of NMES controllers exist because the muscle response to an electrical stimulation is nonlinear and the muscle model...
A significant challenge designers of tidal stream turbines face is ensuring that the device can survive the harsh operating environment. Understanding the effect of the onset flow structure on the loading spectrum of the blades will lead to improved blade designs. The results of a preliminary parametric analysis suggest that the mean flow speed, longitudinal turbulence intensity, wave state and depth...
