Multi‐neighborhood simulated annealing for the home healthcare routing and scheduling problem

International Transactions in Operational Research, Volume 33, Issue 1, Page 38-67, January 2026.
Abstract Over time, the focus on supportive and geriatric care has shifted from being predominantly provided in institutional settings like nursing or rest homes to be delivered within the homes of the patients. Trained caregivers now provide home healthcare services by visiting patients in their own homes and carrying out specific services based on ...

Damage Categorization in Full‐Scale, Full‐Composite Ship Hull Under High‐Energy Impacts by Unsupervised Learning–Enabled Acoustic Emission Monitoring and Laser Shearography Inspection

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
A large, full‐scale (6 m tall, 2.5 m wide) full‐composite ship hull section was subjected to three consecutive impacts with an impact energy level (∼20 kJ) mimicking a realistic heavy crash. The structure was continuously monitored with acoustic emission (AE) sensors during the impacts, which allowed the possible degradation of the composite hull to be
