The use of self-selected intensities of exercise may increase adherence to exercise programs by allowing the participant more freedom to choose activities that are enjoyable. However, self-selected intensities may vary across exercise modes, and participants may not choose an intensity that is adequate to produce health benefits. The purpose of this study(More)
This is first demonstrated using a full 3-D approach, where a global model includes a part of a solar cell with a textured surface. Due to device complexity, many of them cannot be simulated in the full 3-D setup within a reasonable amount of time. Therefore, derived solutions are proposed, which are based on the combined-mode setup coupling the 3-D TCAD(More)
This paper introduces an advanced methodology for fast 3-D TCAD electrothermal simulation for the analysis of complex power devices including package and cooling assemblies. The proposed methodology is based on coupling a 3-D finite element method (FEM) thermal model of the package, 3-D FEM electrical model of the metallization layers and circuit electrical(More)

Kováč) The excessive gate leakage current of the planarand mesa-type InAlN/GaN heterostructure field-effect transistors (HFETs) is evaluated. It is found that the gate current of the mesa-type HFETs is(More)
Automated interaction of SDevice and HSpice for fast 3D electro-thermal simulation based on the relaxation method is designed. The features and limitations of the method are analyzed and presented. A power vertical super-junction MOSFET under the unclamped inductive switching (UIS) test of device robustness is used to perform validation of the designed(More)
