Introduction: Efficient gait control using Functional Electrical Stimulation (FES) is an open research problem. In this research, a new intermittent controller has been designed to control the human shank movement dynamics during gait. Methods: In this approach, first, the three-dimensional phase space was constructed using the human shank movement data recorded from the healthy subjects. Then...

superparamagnetic single phase zinc ferrite nanoparticles have been prepared by coprecipitation method at 20 °c without any subsequent calcination. the composition, crystallite size, microstructure and magnetic properties of the prepared nanoparticles were investigated using x-ray diffraction (xrd), field emission scanning electron microscope (fesem), transmission electron microscope (tem), fou...

Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...

Our aim in this paper is to extend the matched subspace detectors (MSDs) of [1–3] to the detection of stochastic signals. In [1–3] the signal to be detected was assumed to be placed deterministically at an unknown location in a known signal subspace. The basis for the subspace was irrelevant. In this paper the signal is assumed to be placed randomly at an unknown location in a known subspace. I...

This article presents data from 278 six-month-old infants who completed a visual expectation paradigm in which audiovisual stimuli were first presented randomly (random phase), and then in a spatial pattern (pattern phase). Infants' eye gaze behaviour was tracked with a 60 Hz Tobii eye-tracker in order to measure two types of looking behaviour: reactive looking (i.e., latency to shift eye gaze ...

Key points • Expressed by the physiological phasic events of NREM sleep, including arousals, cyclic alternating pattern represents the most complex arrangement of sleep microstructure. • Cyclic alternating pattern is organized in sequences organized in successive cycles. Each cyclic alternating pattern cycle is composed of a phase A (phasic events) and a phase B (background rhythm). • Cyclic al...

Drying of an aqueous suspension containing fine granules leads to the formation a circular pattern, i.e., coffee-ring effect. Here, we report effect mechanical rotation with drying large amount granular particles as in Turkish coffee. It was found that wavy fragmented stripes, or “waggly pattern”, appear early stage process and “polka-dot pattern” many small circles is generated late stage. We ...

we report two cases of focal nodular hyperplasia in patients following gadoxetic acid (gd-eob-dtpa)-enhanced magnetic resonance imaging confirmed with histopathology. these cases showed an atypical pattern during the delayed-hepatobiliary phase after the injection of gadoxetic acid. one case showed a total defect, and the other showed a peripheral ring-like enhancement without a visible central...
