Undertow, Rip Current, and Riptide [PDF]

Journal of Coastal Research, 2012
Abstract Leatherman, S.P., 2012. Undertow, rip current, and riptide. Undertow, rip current, and riptide are terms used to describe a variety of currents, all of which have different characteristics. However, much of the general public, news media, and even dictionary definitions confuse and misidentify these potential hazards at surf beaches.

Microfabrication of Soft Millirobots Propelled by Low Voltage Electrohydraulic Actuators

Advanced Materials Technologies, EarlyView.
Manual layer‐by‐layer assembly is replaced by wafer‐level MEMS batch fabrication for compliant polymer‐based electrohydraulic actuators. The microfabricated devices integrate sacrificially defined microcavities, Parylene‐C‐sealed inlets, and multilayer polymer–metal films.

Beach cusps and inner surf zone processes: growth or destruction? A case study of Trafalgar Beach (Cádiz, Spain)

Scientia Marina, 2010
Large beach cusps (LBC, wavelength of ~ 30 m) are intertidal features that can alternately exist in the swash and in the inner surf zone due to tidal sea level changes. They have a larger cross-shore extent (up to 50 m) than traditional cusps.

Rips, Currents and Snags

Australian and International Journal of Rural Education, 2012
Monash University (Gippsland campus) is situated in Churchill, Latrobe Valley, located in central Gippsland, eastern Victoria. A large percentage of the Gippsland region comprises of a socio-economically disadvantaged population (Figure 1). In Semester One, 2011 as part of the Bachelor of Primary Education course at Monash, it was decided that a ...

Copper Electroplated TPMS Polymer Lattices for Lightweight Absorption Dominant Electromagnetic Interference Shielding

Advanced Materials Technologies, EarlyView.
Copper electroplating transforms lightweight 3D‐printed TPMS polymer lattices into effective electromagnetic shields. Topology, relative density, and conductive seed layer continuity govern copper penetration, electrical resistance, and attenuation. SEA consistently exceeds SER, while 35% RD Diamond lattice gives the best performance, reaching 48.72 dB

A Proof‐of‐Concept Assessment of a Novel Wearable Eyelid Muscle Device: A Pre‐Clinical Animal Cadaver Study for Eyelid Closure Restoration

Advanced Robotics Research, EarlyView.
This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

Development and evaluation of a rip current forecasting system for channel-type rip currents on a low-energy headland beach

Geomatics, Natural Hazards & Risk
A 34-day field observation was conducted on a headland beach in South China with a typical channel rip current system. The Delft3D model was applied to reproduce hydrodynamic conditions and extract rip currents, while a Generalized Additive Model (GAM ...
