The mooring force in a fish cage array subjected to currents and waves is investigated using the finite element method. Firstly, numerical model of with six gravity cages built by Ansys/APDL. Collars bottom rings are simulated pipe beam elements while rest structure link elements, including net cables. Thus, weight hydrodynamic load on cables can be considered. initial shape ropes calculated ba...

Title: A streamlined method for analysing genome-wide DNA methylation patterns from low amounts of FFPE DNA Authors: Aniruddha Chatterjee ([email protected]) Jackie Ludgate ([email protected]) James Wright ([email protected]) Peter Stockwell ([email protected]) Ian Morison ([email protected]) Micheal Eccles ([email protected]) Version: 3 ...

This paper examines the hydroelastic response of a monopile structure, supporting an offshore wind turbine. A new numerical simulation tool is presented, coupling nonlinear potential flow solver to structural model based on modal superposition. The hydrodynamic Weak-Scatterer (WS) approach and assumes small perturbations incident flow. finite element method (FEM) used compute parameters, which ...

Nature-based solutions (NbS) for coastal protection has recently gained increased attention worldwide as a sustainable, economical and eco-friendly alternative to conventional grey structures, particularly under the threat of climate change (Temmerman et al. 2013). Wave energy dissipation by vegetation can be parameterized total horizontal force acting on plant; expressed using Morison-type equ...

This paper presents an algorithm for fast large-change sensitivity computation for approximate symbolic analysis. The sensitivity is used for identifying negligible elements of circuit model that can be removed in order to simplify symbolic solution. The method is based on combination of the Sherman-Morison formula and sparse matrix techniques. Effectiveness of the method was tested on several ...

By analysing a set of thunderstorm-induced events acquired on the Italian north-west coast, separation relevant wind velocity signals into time-varying mean and residual fluctuation is considered. It assumed that, within structural design process, former used for quasi-steady evaluation aerodynamic loads latter to estimate dynamic response. A procedure based continuous wavelet transform propose...

analyzing the vortex-induced vibration of a slender marine structure withlength to diameter ratio up to 200 is the objective of this study. this slender is free to move in both in-line and cross flow directions and immersed completely in water. three different types of shear currents pass on it and cause to vibrate slender in different forms. nowadays, these vibrations are very important for de...

Wave-induced forces on an armour layer unit are key parameters for assessing the stability of rubble mound coastal revetment, but how to predict them accurately and efficiently remains open question. This study explores feasibility using Morison-type equation convert numerically simulated porous media flow in into a single unit. Wave flume tests conducted, which cuboid placed sloped revetment w...
