A unified, closed form analytical drain current model for partially and fully depleted SOS MOSFETs was investigated. The analytical model was developed using first order principles of operation of the device and basic explanation of the physical constraints responsible for hot carriers effects. The approach solved for the channel field to find closed form solutions for the critical voltages giv...

Abstract—Closed die forging is a very complex process, and measurement of actual forces for real material is difficult and time consuming. Hence, the modelling technique has taken the advantage of carrying out the experimentation with the proper model material which needs lesser forces and relatively low temperature. The results of experiments on the model material then may be correlated with t...

The cold compaction of an aggregate of powder is treated from the viewpoint of crystal plasticity theory. The contacts between particles are treated as compaction planes which yield under both normal and shear straining. The hardening of each plane represents both geometric and material hardening at the contacts between particles; the macroscopic tangent stiffness can be written in terms of the...

A closed die forging process was developed to successfully forge an automotive suspension component from AZ80 Mg at a variety of different temperatures (300 °C, 450 °C). The properties the forged were compared and contrasted with other research works on both intermediate full-scale level. monotonic response, as well stress strain-controlled fatigue behaviours, characterized for materials. Stres...

Ressourcenknappheit, Stakeholderforderungen und steigendes Nachhaltigkeits-bewusstsein von Konsumenten drängen Unternehmen dazu, ihre Supply-Chain nachhaltig auszurichten, sodass neben ökonomischen Zielen auch ökologische soziale Aspekte Berücksichtigung finden. Die Closed-Loop Supply Chain spielt als Lösungsansatz in der Diskussion nachhaltiger Wertschöpfungssysteme eine wesentliche Rolle, jed...

flow visualization techniques using tracer markers such as die, smoke, hydrogen bubbles, etc., have been widely used in experimental investigations of large scale structures of a variety of flow fields. they have played an important role in understanding the physics of the coherent structures formation and evolution in the transitional as well as the turbulent regions of the flow fields. howeve...
