Semantic arrangement of navigational safety management terminology

Maritime Technology and Research, 2023
Ensuring ship navigational safety is a complex, multi-faceted problem that can only be solved while considering the human factor and, consequently, the language component of this problem. Terms in general, and navigational terms in particular, comprising the concepts of navigational safety and acting as tools of knowledge, are very important components

MAGTWIST: A Magnetically‐Driven Rotary Actuator Using a Traveling‐Wave With Integrated Stiffness Tunability

Advanced Functional Materials, EarlyView.
MAGTWIST: A compact magnetic rotary actuator, enabling smooth, stepless rotation, and on‐demand locking. Inspired by peristalsis, a soft polymer belt generates a traveling‐wave, enabling 270° rotation when heated. Cooling stiffens the belt, locking it in position and enabling it to withstand high loads.
