Finite Element Analysis of Power Module Packages with One-step Molding for Power Inductors

With the development of 5G communication technology and the rise of power semiconductors, the switching frequency of the circuit keeps increasing, which pushes for miniaturization of power modules and related components. Therefore, in this paper, a one-step molding technology was proposed for a DC/DC buck converter power module. We proposed a...

An end-to-end geometric deficiencies elimination algorithm for 3D meshes

The 3D mesh is an important representation of geometric data. It is widely used in computer graphics and has attracted more attention in computer vision community recently. However, in the generation of mesh data, geometric deficiencies (e.g., duplicate elements, degenerate faces, isolated vertices, self-intersection, and inner faces) are...

Time-dependent mechanical and transport behaviors of Callovo-Oxfordian argillite

An experimental study was carried out on the time-dependent mechanical and transport behaviors of the Callovo-Oxfordian (Cox) argillite, the geological barriers for high-level radioactive waste disposal in France. Six coupled one-step creep tests under the same confining pressure 6MPa and different deviatoric stresses were proposed to...

BQC: A new multi-GNSS data quality checking toolkit

Multi-GNSS networks, for example M-GEX and iGMAS, are set up and grow quickly with the development of new navigation systems and multi-GNSS receivers. It is unavoidable that GNSS signals are deteriorated by several error sources. Thus GNSS network operators, data users and receiver designers all require data quality checking (QC). However, few...

CFD modeling of chemical reactors: Single-Phase Complex Reactions and Fine-Particle Production

Computational fluid dynamics (CFD) is a useful tool for modeling chemical reactors. However, because the design goals and expected outcomes are different than in "traditional'' CFD applications, chemical reactors require special attention to the treatment of chemical reactions, and heat and mass transfer. Here we provide an overview of the...
