Optimal Design of 100–2000 V 4H–SiC Power MOSFETs using Multi-objective Particle Swarm Optimization Algorithms

This work employed the particle swarm optimization (PSO) algorithm to assess the trade-off between breakdown voltage (BV) and on-state resistance (R <i style="box-sizing: border-box;">DS,on</i> ) in 4H–SiC metal oxide semiconductor field effect transistors (MOSFET) for power devices. In this work, the numerical model obtained after analyzing...

The influencing factors of evaporation residue of emulsified modified asphalt to optimize the environmental adaptability

Compared with traditional asphalt, emulsified asphalt occurs to be a better low-temperature usability and environmental adaptability, which can reduce environmental pollution and energy consuming during road construction. The low-temperature ductility is a very important indicator to evaluate the environmental adaptability of emulsified asphalt....

Parametric studies on the water impact of one and twin free-falling wedges by a Cartesian grid multiphase flow model

The water impact of one and twin free-falling wedges is numerically investigated by a Cartesian grid multiphase flow model. The effects of the drop velocity and the gap distance on the hydrodynamic behaviors are parametrically investigated. The numerical model involves a radial basis function ghost cell method (RBFGCM) for treating moving...
