Archaeometry, EarlyView.ABSTRACT Morphological and morphometric analysis of archaeological animal hairs offers a nondestructive method to explore past clothing. We examined hair from two 18th‐century burial areas (SP03 and SP04) in Mazamet, France. SP03 specimens exhibited a continuous medulla, a low medullary index (0.2 ± 0.03) and cuticular features suggesting goat or ...

Scheduling optimization of optical lens polishing
International Transactions in Operational Research, EarlyView.Abstract Optical systems have achieved notable progress in focusing and imaging technologies; however, manual grinding remains indispensable, resulting in elevated costs, extended timelines, and inefficiencies. These difficulties are compounded by operational constraints, uneven machine utilization, and risks of order delays and escalating expenses ...
