In this paper, a BSIMSOI RF gate resistance model for FDSOI MOSFET is introduced and verified. With the addition of the gate resistance model, the RF characteristic of FDSOI MOSFET could be modeled well. Self-heating effect (SHE) will affect RF data fitting significantly. A simple method to extract thermal resistance is proposed.

In this study the thermal conductivity and the volumetric heat capacity of non-Newtonian fluids are investigated. These fluids find many applications in chemical, medical and food industries. They mostly have viscoelastic behavior and generally differ from Newtonian fluids. Two non-Newtonian fluids, solutions of xanthan and carboxy methyl cellulose in water with various concentrations have bee...

Positional accuracy of the machine tool is affected by the instabilities caused by the thermal gradients produced from the internal and external heat sources. Thermal gradients cause linear and non linear thermal expansions of the complex machine parts which result in the generation of the positional error between the tool and the work piece affecting the machining accuracy. Thermal gradients d...

Certain problems in which a cooled rigid punch indents an elastic half-space have no steady state solution. A simple model is described in which it is shown that this paradox is avoided by the assumption of a thermal resistance varying inversely with contact pressure. A limiting case of this system retains linearity and introduces a state of "imperfect" contact in which contact pressure is negl...
