The 'W' prawn-trawl with emphasised drag-force transfer to its centre line to reduce overall system drag. [PDF]
PLoS ONE, 2015 For prawn trawling systems, drag reduction is a high priority as the trawling process is energy intensive. Large benefits have occurred through the use of multiple-net rigs and thin twine in the netting.

ENHANCING THE ENERGY EFFICIENCY OF MARINE FISHING VESSELS
Автоматизация технологических и бизнес-процессов. During each voyage, the vessel's traction capacity decreases due to the gradual degradation of the characteristics of the propulsion complex. This process is influenced by factors such as fouling of the vessel's hull and propeller, a decrease in the ...

Advanced Engineering Materials, EarlyView.A flexure‐based variable stiffness structure is developed by integrating phase‐change modulation and adhesive interfacial locking of gallium. The design enables a wide stiffness variability, transitioning from soft, flexible behavior to rigid, load‐supporting performance.

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures
Advanced Engineering Materials, EarlyView.We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...
