Data-driven modeling and regression analysis on ship resistance of in-service performance
International Journal of Naval Architecture and Ocean EngineeringThis study employs operational data to model ship resistance, aiming to bridge the gap between controlled experiments and real-world conditions. It comprehensively analyzes wind, waves, and currents, employing nonlinear regression and z-score filtering ...

Constant-pressure sound waves in non-Hermitian disordered media
, 2018 When waves impinge on a disordered material they are back-scattered and form a highly complex interference pattern. Suppressing any such distortions in the free propagation of a wave is a challenging task with many applications in a number of different ...

Abnormal wave reflections and left ventricular hypertrophy late after coarctation of the aorta repair [PDF]
, 2017 Patients with repaired coarctation of the aorta are thought to have increased afterload due to abnormalities in vessel structure and function. We have developed a novel cardiovascular magnetic resonance protocol that allows assessment of central ...

A numerical investigation on the nominal wake of KVLCC2 model ship in regular head waves
International Journal of Naval Architecture and Ocean Engineering, 2020 Analysis: of the propulsion performance considering ship motion in waves is an important factor for the efficient operation of a ship. The interaction between the propeller and the free surface due to the ship motion in waves has a significant influence ...

Maintenance of Constant Wave Parameters by Sperm Flagella at Reduced Frequencies of Beat [PDF]
, 1973 1. Treatment of Ciona spermatozoa with low concentrations of Triton X-100 (less than 0·01 %) causes them to beat at lower than normal frequencies. The wavelength of the flagellar bending waves remains constant over the range from 10 to 40 Hz.

Numerical Study of a Model and Full-Scale Container Ship Sailing in Regular Head Waves
InventionsIn the present study, the added resistance, heave, and pitch of the KRISO Container Ship (KCS) in waves, at both model scale and full scale, are predicted numerically in regular head waves, for four wavelengths and three wave heights.

Unsteady effects during resistance tests on a ship model in a towing tank [PDF]
, 2008 It is known that there are oscillations in the wave resistance during the constantvelocity phase of a towing-tank resistance test on a ship model. In this work, the unsteady thin-ship resistance theory has been applied to this case. The results have been
