Hydrodynamics and Sediment Transport Under Solitary Waves in the Swash Zone

open access: yesJournal of Marine Science and Engineering
Swash–swash interaction is a common natural phenomenon in the nearshore region, characterized by complex fluid motion. The characteristics of swash–swash interaction are crucial to sediment transport, subsequently affecting the beach morphology.

Investigation into the Effects of the Variable Displacement Mechanism on Swash Plate Oscillation in High-Speed Piston Pumps

open access: yesApplied Sciences, 2018
High-speed, pressure-compensated variable displacement piston pumps are widely used in aircraft hydraulic systems for their high power density. The swash plate is controlled by the pressure-compensated valve, which uses pressure feedback so that the ...

The effects of tides on swash statistics on an intermediate beach [PDF]

open access: yes, 2011
Swash hydrodynamics were investigated on an intermediate beach using runup data obtained from video images. Under mild, near-constant, offshore wave conditions, the presence of a sandbar and the tidally controlled water depth over its crest determined ...

Biomimetic Iridescent Skin: Robust Prototissues Spontaneously Assembled from Photonic Protocells

open access: yesAdvanced Functional Materials, EarlyView.
Uniform nanoparticles are induced to form arrays (photonic crystals) in the cores of biopolymer capsules, endowing these ‘protocells’ with structural color. These protocells are then assembled into large self‐standing objects, i.e., prototissues, with robust mechanical properties as well as iridescent optical properties.

Intertidal water column meiofauna in relation to wave intensity on an exposed beach

open access: yesScientia Marina, 2004
Since the 1970s, various studies have shown that some meiofaunal taxa frequently occur in the water column. Water currents or any process that disturbs the sediments are possible factors that can facilitate the passive entry of meiofauna in the water ...

An evaluation method of human standing stability by applying the disturbance of swash plate fall

open access: yesNihon Kikai Gakkai ronbunshu, 2021
This paper proposes a swash plate disturbance application device for human standing stability evaluation. It is known that when a mechanical disturbance is applied to the lower body, the COP (center of pressure) trajectory of the human is closely related

Effects of nonuniform swash-plate stiffness on coupled blade-control system dynamics and stability [PDF]

open access: yes, 1972
Program has been developed that analytically determines effects of nonuniform swash-plate support stiffness, swash-plate flexibility, and out-of-blade track on vibratory mechanical stability characteristics of helicopter rotor systems.

Laser‐Based Solidification of Cermets/Cemented Carbides: Processing‐Microstructure‐Property Relationships

open access: yesAdvanced Materials Technologies, EarlyView.
Recent research on laser‐processed cermets and cemented carbides highlights significant advancements, yet a notable paucity of studies and persistent challenges remain. Efforts are increasingly focused on developing low‐cost, environmentally friendly cermets as alternatives to conventional materials.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

open access: yesAdvanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...
