Influence of defects on the irreversible phase transition in the Fe-Pd doped with Co and Mn [PDF]

, 2018
The appearance of BCT martensite in Fe-Pd-based ferromagnetic shape memory alloys, which develops at lower temperatures than the thermoelastic martensitic transition, deteriorates the shape memory properties.

Tutorial Overview: Numerical Synergy in Muffler Acoustic Design A Critical Comparison of TMM, FEM, and CFD Approaches for Transmission Loss Quantification

Engineering Reports, Volume 8, Issue 1, January 2026.
Experimental measurements reveal distinct performance boundaries: TMM achieves rapid convergence (< 2 dB error below 2000 Hz) but neglects 3D wave effects; FEA maintains < 10% deviation up to 3500 Hz with 90% reduced computational cost versus CFD; while transient CFD captures broadband attenuation trends despite 10× higher resource demands.

Investigating Long‐Term Degradation and Defects of Solar Photovoltaic Modules in Tropical Climates: A Case Study of Malaysia

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
This study investigates the degradation of four monocrystalline silicon photovoltaic (PV) modules after nine years of outdoor exposure in Kuala Lumpur, Malaysia's tropical climate. Using visual inspection, electroluminescence, and electrical performance analyses, the modules exhibited an average power loss of 40.35%, primarily due to encapsulant ...
