Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage, Volume 10, Issue 6, Page 1464-1473, December 2025.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐

Development of an Electromagnetic‐Thermal Circuit Model for Single‐Phase Three‐Limb Transformers

High Voltage, Volume 10, Issue 6, Page 1545-1557, December 2025.
ABSTRACT Analysing the heat states of transformers under DC bias requires careful consideration of their own structural and material characteristics. Although the 3D finite element method (FEM) is a reliable way of simulating all the details of transformers, it may be time‐consuming or have encountered convergence difficulties due to the complex ...

Tempus: An Evolutionary Mutation Testing System on Event‐Based Systems With Profile‐Based Individual Generation

Software Testing, Verification and Reliability, Volume 35, Issue 5, August 2025.
Tempus is a testing system that enhances Evolutionary Mutation Testing (EMT) by using ProfileBased individual generation (PBig). PBig generates new individuals based on previous knowledge from other programs about which operators are more likely to produce strong mutants.
