Ship roll stabilization control with low speed loss [PDF]
, 2014 Large roll motion induced by waves can severely affect the ability of vessels and the speed will loss due to added resistance which caused by ship motions, especially in moderate to high sea states. With increasing needs of fuel efficiency and greenhouse

High-Power Hybrid Nanogenerator With Multi-Degree-of-Freedom Mechanical Coupling for Harvesting Water Wave Energy. [PDF]
Adv Sci (Weinh)A high‐power hybrid nanogenerator (HP‐HNG) with multi‐degree‐of‐freedom mechanical coupling is reported, integrating multi‐directional wave energy for output to achieve 1 + 1 > 2 energy harvesting. The HP‐HNG achieves a peak output power of 0.764 W, corresponding to a peak power density of 127.303 W m−3. At a wave frequency of 1 Hz, the HP‐HNG delivers

Basic investigations on the realization of aimed fishing by pelagic otter trawls [PDF]
Acta Ichthyologica et Piscatoria, 1985 The scientific-technical realisation of aimed fishing is an essential precondition for a considerable increase of the efficiency relation between the motions of ship, trawl winch, and trawl, respectively, in required. In the present paper methods for the

Effect of 6-DOF Oscillation of Ship Target on SAR Imaging
Remote Sensing, 2021 Ship targets are high-value military and civilian targets with broad application prospects. However, the precise focusing of ships is still a difficult issue because of their complicated six-degree-of-freedom motions on the sea surface.
