Numerical Research of the Effect of Surface Biomimetic Features on the Efficiency of Tidal Turbine Blades

open access: yesEnergies, 2018
Horizontal-axis axial flow tidal current turbine is regularly used to exploit the kinematic energy in tidal currents. However, the scaling up of tidal current turbine is very difficult.

Relativistic tidal forces

open access: yesThe Astrophysical Journal, 1983
The post-Newtonian, relativistic (1/c/sup 2/) tidal force is calculated within the general PPN framework of all metric theories of gravity. There are no relativistic tides in general relativity, but they are generally nonzero in other metric theories of gravity, including scalar-tensor theories.

NO NĀ PUA: Exploring the feasibility of culture‐based social prescribing on firefighters' wellbeing in Hawaiʻi

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Firefighters face an array of stressors due to the demands of their occupation, leading to a high prevalence of mental health challenges. Social prescribing represents a novel approach to healthcare that emphasizes a holistic view of health and wellbeing.

Participatory Policy Development: Reflections on Designing the Strong Roots for Our Futures Program in Victoria

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT In this paper, we trace the journey to create the Strong Roots for our Futures Program, a government program to resource and support Traditional Owners to undertake a range of activities in areas where no state recognition existed. We provide a background to state recognition in Victoria before considering the program design, leading to an ...

On the effect of channel slope on seepage-driven bank collapse in tidal channels

open access: yesApplied Ocean Research
An accurate description of the morphodynamics of tidal channels relies on a full understanding of bank retreat processes. Bank retreat is usually ascribed to the shear induced by tidal currents and therefore, as the slope of the channel increases, the ...

Geographical analysis of the Pacific and Atlantic Oceans in the Americas: A comparative Study of Tidal Energy Potential [PDF]

open access: yesE3S Web of Conferences
Tidal energy offers a promising renewable energy source, leveraging predictable oceanic forces to generate electricity. However, the potential for tidal energy varies significantly across regions due to geographical and oceanographic factors.

A method for analysing fluid structure interactions on a horizontal axis tidal turbine

open access: yes, 2011
Free stream tidal turbines are rotating bodies in fast flowing tidal currents, and as such are exposed to fluctuating loads from the surrounding fluid.

Numerical modelling of an undulating membrane tidal energy converter

open access: yes, 2020
International audienceThe undulating membrane tidal energy converter is a device that uses the flutter instabilities occurring from the interaction between a slender body and a fluid flow.

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Artificial intelligence techniques for predicting tidal effects based on geographic locations in Ghana

open access: yesGeodesy and Cartography, 2020
Tidal forces as a result of attraction of external bodies (Sun, Moon and Stars) through gravity and are a source of noise in many geoscientific field observations. The solid earth tides cause deformation.
