Slamming response analysis of global load for large-bow flare naval ship in rough sea
Zhongguo Jianchuan YanjiuObjectivesWhen a large-bow naval ship encounters adverse sea conditions, bow flare slamming causes a hull girder whipping response which threatens the security of global longitudinal strength.

IR-excesses around nearby Lambda Boo stars are caused by debris disks rather than ISM bow waves
, 2015 Lambda Boo stars are predominately A-type stars with solar abundant C, N, O, and S, but up to 2 dex underabundances of refractory elements. The stars' unusual surface abundances could be due to a selective accretion of volatile gas over dust. It has been

Study on the Resistance of a Large Pure Car Truck Carrier with Bulbous Bow and Transom Stern
Journal of Marine Science and Engineering, 2023 The resistance of a large Pure Car Truck Carrier (PCTC) with a bulbous bow and a transom stern is evaluated in the present paper. Several cases at nine different ship speeds in calm water are simulated and results are compared with the experimental ...

Optimal design method of bulbous bow for fishing vessels
International Journal of Naval Architecture and Ocean Engineering, 2021 Although widely used, the design of the bulbous bow for ships has been difficult due to the complex interference between the wave system generated by the bulb and the wave system of the ship hull.

Whistler mode waves upstream of Saturn [PDF]
, 2016 Whistler-mode waves are generated within and can propagate upstream of collisionless shocks. They are known to play a role in electron thermodynamics/acceleration and, under certain conditions, are markedly observed as wave trains preceding the shock ...

Multiple spacecraft observations of interplanetary shocks: Characteristics of the upstream ULF turbulence [PDF]
, 1982 All interplanetary shocks observed by ISEE-3 and either ISEE-1 or ISEE-2 or both in 1978 and 1979 are examined for evidence of upstream waves. In order to characterize the properties of these shocks it is necessary to determine accurate shock normals. An
