Numerical investigation of the three-dimensional velocity fields induced by wave-structure interaction [PDF]
, 2019 Submerged shore-parallel breakwaters for coastal defence are a good compromise between the need to mitigate the effects of waves on the coast and the ambition to ensure the preservation of the landscape and water quality.

Estimations of rip current rescues and drowning in the United States [PDF]
Natural Hazards and Earth System Sciences, 2019 Rip currents are the greatest hazard to swimmers on surf beaches, but due to a lack of consistent incident reporting in many countries, it is often difficult to quantify the number of rip-current-related rescues and drowning deaths occurring along surf ...

Wave-Filtered Surf Zone Circulation under High-Energy Waves Derived from Video-Based Optical Systems
Remote Sensing, 2021 This paper examines the potential of an optical flow video-based technique to estimate wave-filtered surface currents in the nearshore where wave-breaking induced foam is present.

ISO efficiency curves of a two-phase hybrid stepping motor [PDF]
, 2010 Stepping motors are used in numerous applications because of their low manufacturing cost and simple speed control. It is well known that their energetic efficiency is low but actual values are typically not available.

RipFinder: real-time rip current detection on mobile devices
Frontiers in Marine ScienceRip currents present a significant safety risk to beach tourists and coastal communities, resulting in hundreds of annual drownings all over the world. A key contributing factor to this danger is the lack of awareness among beachgoers about recognizing ...

Infragravity rip current pulsations [PDF]
Journal of Geophysical Research: Oceans, 2004 The origins of rip current pulsations within the infragravity frequency band (0.004–0.04 Hz) are determined from measurements made with arrays of colocated pressure and velocity sensors deployed on a beach with persistent rip current channels. The observations indicate significant energy in cross‐shore infragravity velocities that varies spatially in ...

Coastal Engineering, 2006 Rip currents are shore-normal, narrow, seaward-flowing currents that originate within surf zone, extend seaward of the breaking region (rip head), and can obtain relatively high velocities. Within the last decade, there have been a significant number of laboratory and field observations within rip current systems.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Super‐Refractory Status Epilepticus (SRSE) is a rare, life‐threatening neurological emergency with unclear etiology in many cases. Mitochondrial dysfunction, often due to disease‐causing genetic variants, is increasingly recognized as a cause, with each gene producing distinct pathophysiological mechanisms.

New insights into combined surfzone, embayment, and estuarine bathing hazards [PDF]
Natural Hazards and Earth System SciencesRip currents are the single largest cause of beach safety incidents globally, but where an estuary mouth intersects a beach, additional flows are created that can exceed the speed of a typical rip current, significantly increasing the hazard level for ...
