We studied the heating efficiency of an electrically heated vest (EHV), its relationship to the microclimate temperature distribution in a three-layer clothing ensemble, and the effect of an EHV on the clothing's total thermal insulation by both theoretical analysis and thermal manikin measurements. The heat losses at different ambient conditions and heating states were recorded and the heating...

The action of ketamine upon spontaneously active and electrically driven Purkinje fibres of the moderator band of the pig heart has been studied using a floating microelectrode technique. Ketamine hydrochloride altered the transmembrane potential in a dose-related and reversible manner. Concentrations of 1X 10M were subthreshold whereas 5 X 10'M and 1X 10~M slowed the frequency and increased th...

This paper addresses the dynamic path planning for two mobile robots in unknownenvironment with obstacle avoidance and moving target tracking. These robots must form atriangle with moving target. The algorithm is composed of two parts. The first part of thealgorithm used for formation planning of the robots and a moving target. It generates thedesired position for the robots for the next step. ...

Random lasers are intriguing devices with promising applications as light sources for imaging, sensing, super-resolution spectral analysis or complex networks engineering. can be obtained from optically pumped dyes, optical fibres and crystals electrically semiconductor heterostructures. Semiconductor random usually fabricated by introducing scattering defects into the active layer, adding a de...
