The numerical simulation of the rehabilitation to walking of disabled people by Functional Electric Stimulation can offer new tools in the design and optimization of stimulation patterns, but some Hybrid Dynamics need to be taken into account. We propose here a specific time-integration scheme for such dynamical systems, with a particular emphasis on the various measures that need to be underta...

Microelectrodes and ultramicroelectrodes (UMEs) have been the subjects of intense studies in electrochemical sensing 9 and in electrical energy storage and conversion. 21 Microelectrodes and ultramicroelectrodes refer to electrodes with characteristic sizes less than 25 μm. 6 These electrodes have been used extensively in different scanning probe microscopy techniques. 28 For example, scanning ...

With the increased use of sensitive electronic circuitry, customers become more concerned about the electric power quality (PQ). In the new open-access and competitive power market, electricity consumers are in a unique position to demand a higher quality of service. The utilities or other power providers have to ensure a high quality of their service to remain competitive and retain/attract th...

This article is an introduction to modern issues about controllability of Schrödinger PDEs with bilinear controls. This model is pertinent for a quantum particle, controlled by an electric eld. We review recent developments in the eld, with discrimination between exact and approximate controllability, in nite or in nite time. We also underline the variety of mathematical tools used by various t...

Hydraulic differential electric servo cylinders are electromechanical tools applicable for driving e.g. manipulators. Actual models are strongly nonlinear, coupled systems of differential equations. In the present paper we propose a new model using fuzzy differential equations under strongly generalized differentiability concept. The key point is a continuous fuzzyfication of the signum functio...

The rapid progress of interest in carbon nanotubes research have been improved with a development of sensitive tools for their observation and characterization. In this work Raman spectroscopy and atomic/electric force microscopy (AFM/EFM) have been successfully applied for studying electrical and structural properties of multiwall carbon nanotubes (MWNT). The combination of these methods (Rama...

the computer simulation program of a practical scale reverse electrodialysis process has been developed based on the program for saline water electrodialysis. the program is applied to compute the performance of an industrial-scale reverse electrodialysis stack (effective membrane area s = 1 m × 1 m = 1 m2, cell pair number n = 300 pairs). the stack operatingconditions are optimized. seawater a...

As a result of the increasing consumer demand for minimally-processed fresh-like food products with high sensory and nutritional qualities, there is a growing interest in non-thermal processes for food processing and preservation. Key advanced technologies such as high-pressure processing, pulsed electric fields, dense gases and ultrasound are being applied to develop gentle but targeted proces...
