Abstract: A tidal bore is a positive surge taking place during the flood tide under macro-tidal conditions and the bore represents the leading edge of the tidal wave propagating upstream. The fundamentals of tidal bores remain unknown, although some physical experiments were performed during the last two decades. In this study, some physical modelling was performed to investigate the tidal bore...

Added mass and damping play a significant role in accurate prediction of floating wind turbine (FWT) motions, especially near the resonance frequencies. This paper investigates still-water hydrodynamic characteristics semi-submersible FWT around natural periods surge, heave pitch motion. A higher-fidelity tool (Computational Fluid Dynamics, CFD) based on OpenFOAM is employed numerical computati...

Spatial orientation is critical for air operations. Perception of orientation is continuously maintained by accurate information from the visual, vestibular, and somatosensory systems in daily terrestrial activities. The various contributions of these senses can be significantly altered in variable gravitoinertial environments, or when one of the sensory cues is markedly reduced. The visual ori...

This paper examines the problem of realizing a 6-DOF motion platform by proposing a closed loop kinematic architecture that benefits from an anthropological serial manipulator design. In contrast to standard motion platforms based on linear actuators, a mechanism with actuator design inspired from anthropological kinematic structure offers a relatively larger motion envelope and higher dexterit...

Sea level, currents, and ice distribution are studied in the Bering Sea during storm events. The ice and ice edge are incorporated into storm surge model. The interaction of wind, ice, and water is expressed by the normal and tangential stresses. A numerical grid is established for the Bering Sea, and a second refined grid is constructed for Norton Sound. Construction of open boundary condition...

This document is included in the Annex of Part 7 as historical background of a well-intentioned task that was completed at too slow a pace, missing its target date for serving as a reference for other in-process IEC standards projects concerned with low-voltage surge-protective devices. For the sake of historical accuracy and perspective, the document is presented here in its draft form, includ...

Understanding how humans walk on a surface that can move might provide insights into, for instance, whether walking humans prioritize energy use or stability. Here, motivated by the famous human-driven oscillations observed in the London Millennium Bridge, we introduce a minimal mathematical model of a biped, walking on a platform (bridge or treadmill) capable of lateral movement. This biped mo...

Understanding the dynamics of an FWT (Floating Wind Turbine) is essential for its design and operation. Since a truss structure can reduce wave load/resistance on floating foundation, it becomes more popular in industrial applications. In this regard, knowing effect slender members motion response characteristics such vital. The present work develops time-domain method modeling truss-structure ...

modeFRONTIER 2012 Users’ Meeting Title Enhancing MPC based Motion Cueing algorithm using modeFRONTIER Authors Eddi Valvason (VI-Grade), Mattia Bruschetta (University of Padua) Driving simulators are widely used in different applications: driver training, vehicle development, and medical studies. To fully exploit the potential of such devices, it is crucial to develop motion control strategies t...

Several insects require both olfactory and visual cues during odour-source localisation to successfully locate an odour source. In the male silkmoth, Bombyx mori, detection of the female sex pheromone triggers a programmed walking pattern, starting from a surge (straight-line walking) followed by zigzag walking. Although pheromone-triggered behaviour in silkmoths is well understood, the role of...
