This paper presents a new high temperature chipset specially designed for high-reliability and high-density DC-DC Converters and Motor Drive applications. Integrated circuits (IC's) such as Pulse-Width-Modulation (PWM) controllers and half-bridge drivers as well as power n-channel MOSFET's transistors have been optimized to meet the strong requirements of(More)

Neutral impact collision ion scattering spectroscopy under normal incidence is known to yield the concentration depth profiles of all elements except hydrogen at the surface of liquids and other amorphous material. In the evaluation of the data one tactically has to assume that the top surface layer and the adjacent layers are laterally homogeneous. In the(More)
The present study was designed to investigate biomechanical and clinical changes in the mandibular complex by means of finite element analysis. An analytical model developed from human native mandibles was used for this model, CT image data were transferred to a computer, and an edge extraction program generated the cross-section of bone by specifying a(More)
