Part II: Structural response and tank contact assessment of hydrogen tank trailer protective housing under AI-augmented probabilistic multi-directional collision loading

High-pressure hydrogen tank trailers are entering road transport in growing numbers, but the structural conditions under which a vehicular collision reaches the cylinder assembly have not been characterised. UN GTR No. 13 and FMVSS No. 307/308 govern post-crash containment and do...

Fatigue Crack Growth in Rubber: Comparability of Test Results, Material Effects and Transfer to Component Life—A Critical Review

Fatigue crack growth (FCG) relations rank rubber compounds and predict component life, yet a reported rate–tearing-energy curve depends on how it was measured as well as on the compound. This critical review treats the test variables as criteria for deciding whether two results m...

Exhaust Emission Characteristics of Gasoline Engines with Secondary Air Systems and Electrically Heated Catalysts in Cold-Start WLTC Mode

Abstract Cold-start emissions remain a critical barrier to achieving near-zero tailpipe emissions required by increasingly stringent global regulations. Because gasoline direct-injection (GDI) engines experience incomplete combustion and delayed catalyst activation during the col...

Calibration Robustness and Cross-Device Transferability of Four Temperature-Sensitive Electrical Parameters in Enhancement-Mode GaN HEMTs

Reliable temperature estimation in GaN high-electron-mobility transistors requires temperature-sensitive electrical parameters (TSEPs) that combine sufficient sensitivity with stable calibration behavior. This study compares on-state resistance (Rds(on)), threshold voltage (Vth),...
