Set-Up Due to Irregular Waves

Coastal Engineering 1972, 1972
Energy losses in breaking irregular waves are estimated on the assumption that a wave, while breaking, loses only that portion of its height which would be in excess of the breaker height for the given wave period and the mean local depth. This leads to expressions for the magnitude of the radiation stresses as a function of the distance offshore. From

Active Absorption of Nonlinear Irregular Waves [PDF]

, 2018
In the present paper, the performance of active absorption systems based on nearfield surface elevation measurements is studied. Based on linear wavemaker theory the performance of such systems can easily be calculated for linear waves.

Statistics of surface gravity wave turbulence in the space and time domains [PDF]

, 2010
We present experimental results on simultaneous space–time measurements for the gravity wave turbulence in a large laboratory flume. We compare these results with predictions of the weak turbulence theory (WTT) based on random waves, as well as with ...

Hydrodynamics under large-scale regular and bichromatic breaking waves [PDF]

, 2018
Multiphase CFD models recently have proved promising in modelling cross†shore sediment transport and morphodynamics (Jacobsen et al 2014). However, modelling breaking wave turbulence remains a major challenge for these models, because it occurs at very

A RANS Modelling Approach for Predicting Powering Performance of Ships in Waves

, 2013
In this paper, a modelling technique for simulating selfpropelled ships in waves is presented. The flow is modelledusing a RANS solver coupled with an actuator diskmodel for the propeller.

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 ...

Parametric resonance analyses for spar platform in irregular waves [PDF]

, 2018
The parametric instability of a spar platform in irregular waves is analyzed. Parametric resonance is a phenomenon that may occur when a mechanical system parameter varies over time.

Characteristics of a series of high speed hard chine planing hulls - part II: performance in waves

, 2011
An experimental investigation into the performance of high speed hard chine planing hulls in irregular waves has been conducted. A new series of models representative of current design practice was developed and tested experimentally. Measurements of the

A 17 Year Old With Developmental Delay Presenting With Increasing Confusion and Imbalance

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Methylmalonic acidemia is an autosomal recessive genetic disorder primarily caused by defects in methylmalonyl‐CoA mutase and cobalamin (vitamin B12) metabolism. These defects disrupt the tricarboxylic acid cycle and oxidative phosphorylation, leading to the abnormal accumulation of metabolic products such as methylmalonic acid, propionic acid,
