Transformation of Irregular Waves in Shoaling Water
Coastal Engineering 1974, 1974 In the numerical method of prediction of wind waves in deep water, Hasselmann's nonlinear interaction theory is applied. This method assumes the energy balance of individual component waves. However, the total energy balance must exist in the transformation of irregular waves in shoaling water. In this investigation, experiments were carried out on the

Orbital Velocities in Irregular Waves
Coastal Engineering 1980, 1980 Experimental and theoretical study to determine the applicability of linear wave theory for the description of the velocity field in irregular waves. A comparison between theory and measurement was executed both in frequency and in time domain. In frequency domain by means of the experimentally and theoretically determined frequency response functions ...

Irregular Coulomb Wave Functions [PDF]
Australian Journal of Physics, 1959 In a recent paper (Learner and Robson 1958), henceforth referred to as I, a skeleton table of values of the regular Ooulomb wave functions was given in the integral representation.

Polish Maritime Research, 2021 The most common methods for predicting ship roll motions in a specified sea state are direct measurements of motions in a representative irregular wave realisation (time domain) or calculations of motions from response amplitude operators (RAOs) in the ...

IRREGULAR WAVE LOADING ON A CONICAL STRUCTURE
Coastal Engineering Proceedings, 1988 The horizontal forces, vertical forces and overturning moments exerted by waves on a fixed model of a 45" conical structure are presented. Irregular wave loading tests were conducted for a range of conditions described by base diameter on peak period wave length D/Lp from 0.31 to 1.76, water depth on peak period wave length h/Lp from 0.11 to 0.63, and ...

SensorsThe propagation of shallow-water waves may cause liquefaction of the seabed, thereby reducing its support capacity for pipelines and potentially leading to pipeline settlement or deformation.

Towards active microfluidics: Interface turbulence in thin liquid films with floating molecular machines [PDF]
, 2008 Thin liquid films with floating active protein machines are considered. Cyclic mechanical motions within the machines, representing microscopic swimmers, lead to molecular propulsion forces applied to the air-liquid interface. We show that, when the rate

Slow Drift-Oscillations of a Ship in Irregular Waves [PDF]
Modeling, Identification and Control, 1980 A procedure to calculate horizontal slow drift excitation forces on an infinitely long horizontal cylinder in irregular beam sea waves is presented. The hydrodynamic boundary-value problem is solved correctly to second order in wave amplitude. Results in

Spatial organization and evolutional period of the epidemic model using cellular automata
, 2006 We investigate epidemic models with spatial structure based on the cellular automata method. The construction of the cellular automata is from the study by Weimar and Boon about the reaction-diffusion equations [Phys. Rev. E 49, 1749 (1994)]. Our results

Applied Ocean ResearchUnderstanding the condition of a ship during operation is crucial for ensuring hull safety. This can be achieved either by directly monitoring the ship's hull or by using response estimation models when the wave field is known.
