Numerical Modeling and Dynamic Analysis of a Wave-Powered Reverse-Osmosis System
Journal of Marine Science and Engineering, 2018 A wave energy converter (WEC) system has the potential to convert the wave energy resource directly into the high-pressure flow that is needed by the desalination system to pump saltwater to the reverse-osmosis membrane and provide the required pressure ...

A Parametric Study of Wave Energy Converter Layouts in Real Wave Models
Energies, 2020 Ocean wave energy is a broadly accessible renewable energy source; however, it is not fully developed. Further studies on wave energy converter (WEC) technologies are required in order to achieve more commercial developments.

van Vleck determinants: geodesic focussing and defocussing in Lorentzian spacetimes
, 1993 The van Vleck determinant is an ubiquitous object, arising in many physically interesting situations such as: (1) WKB approximations to quantum time evolution operators and Green functions. (2) Adiabatic approximations to heat kernels.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This paper proposes a hybrid sensorless control strategy for a permanent magnet synchronous generator (PMSG)‐based wind energy conversion system (WECS). The approach integrates finite‐set predictive current control (FS‐PCC), a model reference adaptive system (MRAS) estimator and an optimal torque control maximum power point tracking (MPPT‐OTC) method ...

Optimization of Wave Energy Converter Arrays by an Improved Differential Evolution Algorithm
Energies, 2018 Since different incident waves will cause the same array to perform differently with respect to the wave energy converter (WEC), the parameters of the incident wave, including the incident angle and the incident wave number, are taken into account for ...

Hydrodynamics of the Oscillating Wave Surge Converter in the open ocean [PDF]
, 2012 A potential flow model is derived for a large flap-type oscillating wave energy converter in the open ocean. Application of the Green's integral theorem in the fluid domain yields a hypersingular integral equation for the jump in potential across the ...

Firm technological responses to regulatory changes: A longitudinal study in the Le Mans Prototype racing [PDF]
, 2018 Despite the critical role of regulations on competition and innovation, little is known about firm responses and related effects on performance under regulatory contingencies that are permissive or restrictive. By longitudinally investigating hybrid cars
