Time Scale for Scour Beneath Pipelines Due to Long-Crested and Short-Crested Nonlinear Random Waves Plus Current

open access: yesJournal of Marine Science and Engineering, 2021
This article derives the time scale of pipeline scour caused by 2D (long-crested) and 3D (short-crested) nonlinear irregular waves and current for wave-dominant flow.

Propagating Waves Can Explain Irregular Neural Dynamics [PDF]

open access: yesThe Journal of Neuroscience, 2015
Cortical neuronsin vivofire quite irregularly. Previous studies about the origin of such irregular neural dynamics have given rise to two major models: a balanced excitation and inhibition model, and a model of highly synchronized synaptic inputs. To elucidate the network mechanisms underlying synchronized synaptic inputs and account for irregular ...

Termination of Reentry in an Inhomogeneous Ring of Model Cardiac Cells [PDF]

open access: yes, 2002
Reentrant waves propagating in a ring or annulus of excitable media model is the basic mechanism underlying a major class of irregular cardiac rhythms known as anatomical reentry.

Influence of steady and turbulent wind on motions, mooring tension, and fatigue performance of a steel OO-Star floating offshore wind turbine

open access: yesFrontiers in Energy Research
Floating offshore wind turbines (FOWTs) often operate under turbulent wind conditions. However, to enhance computational efficiency, steady wind is sometimes used as an alternative to turbulent wind, potentially resulting in conservative estimates ...

Frequency- and time-domain analysis of a multi-degree-of-freedom point absorber wave energy converter

open access: yesAdvances in Mechanical Engineering, 2017
This study proposes a multi-degree-of-freedom wave energy converter and introduces a 6-PSS (prismatic pair–spherical pair–spherical pair) power take-off mechanism.

Numerical Analysis of the Submerged Horizontal Plate Device Subjected to Representative Regular and Realistic Irregular Waves of a Sea State

open access: yesFluids
This study numerically analyzes a submerged horizontal plate (SHP) device subjected to both regular and irregular waves. This device can be used either as a breakwater or a wave energy converter (WEC).

Spatial organization and evolutional period of the epidemic model using cellular automata

open access: yes, 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

A comprehensive study on ship motion and load responses in short-crested irregular waves

open access: yesInternational Journal of Naval Architecture and Ocean Engineering, 2019
Wave-induced ship motion and load responses are usually investigated on the assumption that the incident waves are long-crested. The realistic sea waves are however short-crested irregular waves.

Surface wave modelling and simulation for wave tanks and coastal areas [PDF]

open access: yes, 2011
For testing ships and offshore structures in hydrodynamic laboratories, the sea and ocean states should be represented as realistic as possible in the wave tanks in which the scaled experiments are executed.

A power take-off and control strategy in a test wave energy converter for a moderate wave climate [PDF]

open access: yes, 2016
The energy in the waves of oceans and seas can be converted to electricity by different types of Wave Energy Converters (WECs). Wave energy conversion is currently widely studied to contribute to the world’s rising energy needs.
