Simulation of Life Raft Motions on Irregular Wave - An Analysis of Situations Leading to Raft Capsizing

open access: yesPolish Maritime Research, 2018
Successful rescue action at sea is based on a. o. a correct choice of rescue means and their reliability. Operational characteristics of life-saving appliances determine their performance in a given water area.

Determination of the spectra of solutions of boundary value problems for guiding structures using the transition to integral equations

open access: yesФизика волновых процессов и радиотехнические системы, 2019
The vast majority of guiding structures are described [13] by non-self-adjoint electrodynamic operators, which are understood as the totality of the differential equation and the system of boundary conditions.

OPTIMAL DESIGN FOR WAVE SPECTRUM ESTIMATES

open access: yesCoastal Engineering Proceedings, 1974
Non-stationarity in an actual wave field restricts the application of the existing methods of estimating spectra. Despite the enormous amount of research work in the past, an analyst today is still faced with the lack of a unique procedure capable of providing a spectrum estimate which can be considered as the most accurate for the wave data collected ...

A Review of Parametric Descriptions of Tropical Cyclone Wind-Wave Generation

open access: yesAtmosphere, 2017
More than three decades of observations of tropical cyclone wind and wave fields have resulted in a detailed understanding of wave-growth dynamics, although details of the physics are still lacking. These observations are presented in a consistent manner,

Calculation of the wave spectra of shielded waveguides with arbitrary dielectric filling using the modified Galerkin method and the partial domain method

open access: yesФизика волновых процессов и радиотехнические системы, 2020
We consider a method for calculating the natural wave spectra of round and rectangular shielded waveguides with arbitrary dielectric filling, which is a modification of the Galerkin method and based on the representation of the wave fields of the guiding

Accuracy Evaluation of CFOSAT SWIM L2 Products Based on NDBC Buoy and Jason-3 Altimeter Data

open access: yesRemote Sensing, 2021
Chinese-French Oceanography Satellite (CFOSAT), the first satellite which can observe global ocean wave and wind synchronously, was successfully launched On 29 October 2018. The CFOSAT carries SWIM that can observe ocean wave on a global scale.

Spectrum of the M5-traveling waves [PDF]

open access: yesMathematical Modelling of Natural Phenomena, 2020
In this paper, we study the essential spectrum of the operator obtained by linearizing at traveling waves that occur in the one-dimensional version of the M5-model for mesenchymal cell movement inside a directed tissue made up of highly aligned fibers. We show that traveling waves are spectrally unstable in L2(ℝ; ℂ3) as the essential spectrum includes ...

Ocean Wave Parameters Retrieval from TerraSAR-X Images Validated against Buoy Measurements and Model Results

open access: yesRemote Sensing, 2015
An ocean surface wave retrieval algorithm, Parameterized First-guess Spectrum Method (PFSM), which was initially developed for C-band Synthetic Aperture Radar (SAR), is modified to extract wave parameters from X-band TerraSAR-X (TS-X) images.

Investigation of Ship-Induced Hydrodynamics and Sediment Suspension in a Heavy Shipping Traffic Waterway

open access: yesJournal of Marine Science and Engineering, 2020
In order to investigate the complex hydrodynamics and associated sediment movement resulting from the ship passages in heavy shipping traffic waterways, field measurements were performed in a heavy shipping traffic waterway. Based on the collected waves,

Current mapping from the wave spectrum

open access: yes, 2021
In this chapter we review methods by which near--surface ocean currents can be measured remotely using images of the water surface, as obtained by X-band radar in particular. The presence of a current changes the dispersive behavior of surface waves, so our challenge is to solve the inverse problem: to infer the spatially-varying current from ...
