The morphological evolutions of FePt–X (segregant) thin films were studied by employing a 3-D phase field model. Numerical simulation results show that in the absence of substrate constraint related with elastic energy, the morphology of the FePt–X thin films significantly depends on the interfacial energy, film thickness, and anisotropic atomic mobility. The large interfacial energy between FePt...
Stator bar transposition is a key technology in the electromagnetic design of water-cooled turbo-generator. Transposition bars are located in the slot within the scope of different leakage magnetic fields, circulating current and additional loss are produced among the parallel strands connected by the end nose, which bring the local overheating and seriously affect the operation safety. In engineering,...
A 10 MW class synchronous wind generator that has both the field and armature windings superconducting is presented. The field winding is assumed to be made of YBCO tapes while multifila-ment MgB2 wires are considered for the armature winding. The proposed design is analyzed using a 3-D finite element based on simulation tool MAXWELL 14.0. The magnetic flux distribution figure of the proposed model...
We demonstrate advanced modeling and optimization of 32nm high-K metal gate (HKMG) SOI CMOS technology for high-speed digital and RF/analog system-on-chip applications. To enable high-performance RF/analog circuit design, we present challenging device modeling features and their enhancements. At nominal Lpoly, floating-body NFET and PFET demonstrate peak fT of 300GHz and fMAX of higher than 350GHz...
