Region‐of‐interest geometry optimization for shooting‐distance estimation from flash‐pulse infrared thermography of gunshot residue on textile targets

Journal of Forensic Sciences, EarlyView.
Abstract Shooting‐distance estimation from gunshot‐residue (GSR) patterns on textiles is affected by substrate properties, residue distribution, and region‐of‐interest (ROI) definition. This study evaluated how ROI geometry influences muzzle‐to‐target distance regression from flash‐pulse infrared thermography of GSR‐related thermal patterns.

Crack Process Investigation in Gears Under Single Tooth Bending Fatigue Condition Using Infrared Thermography and 3D XFEM Numerical Models

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT The present study proposes a combined approach of infrared thermography and 3D XFEM numerical models for crack process investigation in mechanical components such as gears. Over the years, fatigue crack analysis based on energy dissipations in the form of heat generated during fatigue tests has been widely reported, although mainly limited to ...

Direct Integration of Calcium Nitrate Tetrahydrate PCM Into an Oscillating Heat Pipe for Passive Lithium‐Ion Battery Thermal Management

Battery Energy, Volume 5, Issue 6, November 2026.
A passive battery thermal management system integrating calcium nitrate tetrahydrate (CaNT) phase‐change material directly within a closed‐loop oscillating heat pipe simultaneously provides latent heat storage and oscillatory heat transport. The hybrid system lowers thermal resistance, improves temperature uniformity, enhances exergy efficiency, and ...
