We have examined the temperature dependence of motions in a cryosolution of the enzyme glutamate dehydrogenase (GDH) and compared these with activity. Dynamic neutron scattering was performed with two instruments of different energy resolution, permitting the separate determination of the average dynamical mean square displacements on the sub-approximately 100 ps and sub-approximately 5 ns time...
In this work a numerical investigation of transient temperature profile of laser beam welding process is carried out. A 3-D finite element modelling isdevelopedconsidering combined double-ellipsoidalheat source model for both spot and moving heat source. The temperature dependent thermo-physical material property of Ti-6Al-4V alloy isincorporated. The effect of latent heat of fusion and convect...
Multi-finger power SiGe heterojunction bipolar transistors (HBTs) with emitter ballasting resistor and non-uniform finger spacing are fabricated, and temperature profiles of them are measured. Experimental results show that both of them could improve the temperature profile compared with an HBT which has uniform finger spacing. For the HBT with emitter ballasting resistor, the ability to lower ...
