Abstract Models and experimental data are used to predict the performance of large area pressure contact IGBTs, offering ratings equivalent to the largest power conventional technology devices. Differences in the electromechanical characteristics of pressure contact devices, when compared to substrate mounted devices, are reviewed and how these influence the potential performance of devices wit...

The pressure distribution was measured for subjects sitting on a flat, hard and horizontal support. The pressure data were analyzed for the seat force, the magnitude of the contact area, the average pressure in the contact area, the maximum pressure, and the pressure gradient. Using multiple regression relationships were found between these pressure distribution parameters, the body characteris...

BACKGROUND The aim of this study was to provide information on algometric transmission of pressure through the dorsal thoracolumbar tissues of the equine back. Using a commercially available algometer, measurements were carried out with six different tips (hemispheric and cylindrical surfaces, contact areas 0.5 cm2, 1 cm2, and 2 cm2). In nine live horses the threshold of pressure that lead to a...

This study addressed the question of whether the level of compressive load would affect the conclusions from statistical analyses aimed at determining how well a lateral meniscal autograft restores tibial contact (as indicated by the maximum contact pressure, mean pressure, and contact area) to that of the intact knee. If statistical analyses indicated that normal tibial contact was not restore...

The resistance of HCl solution without supporting electrolyte at a microelectrode was evaluated by the ac impedance technique of which the dc-potential was in the diffusion-controlled domain for the reduction of the hydrogen ion. The hydrogen ion is reduced to hydrogen gas. The Cl takes the same concentration profile as the hydrogen ion in order to keep electric neutrality. Then, no ion is pres...
