We report a preliminary implementation of an interactive system that enables a draftsperson using only the standard features of a commercial CAD package (AutoCAD) to construct a model-based vision program. Some of the information needed by the model-based vision program is computed automatically from the drawing, but the draftsperson can also provides guidance on expected image-feature types by...

To enable the designers to design and modify model of nuclear channel head quickly and easily, we constructed the CAD system of the nuclear channel head. At first, we analyzed the geometric characteristics of nuclear channel, established of feature control parameter set and the parametric model of nuclear channel head. Secondly, other parameters related to the solid modeling are described throu...

The objective of this study is to investigate the accuracy of the TracerCAD system in measuring a model of known dimensions and volumes. A cylindrical nylon 6.6 model was prepared. Landmarks were added to indicate proximal, distal, anterior, medial, and lateral. Four additional landmarks were added at regular intervals along the length of the cylinder with a view to calculating diameters and vo...

background and objectives: coronary artery disease (cad) is regarded as the leading cause of morbidity and mortality around the world. diabetes mellitus (dm) is associated with the development of cad and increased risk of morbidity and mortality. the goal of this study was to assess the association of tumor necrosis factorα (tnf-α) and high sensitivity c-reactive protein (hscrp) with cad severi...

This paper addresses the device physics of a novel vertical power MOSFET through detailed TCAD simulation. The simulated I-V and C-V characteristics match well with the measured data. The bias dependence of electrical potential near the recess trench is identified as the cause of a sharp drop in output capacitance against drain voltage. Index Terms — power MOSFET, output capacitance, TCAD

Low-power wireless system design requires optimization at all levels of the design abstraction. Sub-1V operation is the key to lowpower design and requires modification of the process technology (e.g., multiple threshold devices, variable threshold devices using bulk biasing or dual-gate SO1 technology, etc.), circuit optimization, and architecture optimization. The CAD tool requirements for th...

Vertical Double Diffused MOSFET (VDMOS) is an established technology for high-current power switching applications such as automotive circuits. The most serious failure mode is destructive damage during inductive switching, resulting from avalanche breakdown of the forward blocking junction in the presence of high current flow. Improving the ruggedness of the device is achieved by enhancing its...
