Ocean energy:the wave of the future [PDF]

open access: yes, 2008
The power point presentation discussed the developing technology of ocean energy with design convergence on tidal but not on wave. Today's technologies will help solve the immediate needs, but we need to work hard nurturing tomorrow's low carbon ...

Frequency-Based Performance Analysis of an Array of Wave Energy Converters around a Hybrid Wind–Wave Monopile Support Structure

open access: yesJournal of Marine Science and Engineering, 2020
In this paper, we investigate, in the frequency domain, the performance (hydrodynamic behavior and power absorption) of a circular array of four semi-immersed heaving Wave Energy Converters (WECs) around a hybrid wind–wave monopile (circular cylinder ...

Weighted Effect Coding for Observational Data with wec [PDF]

open access: yesThe R Journal, 2017
Weighted effect coding refers to a specific coding matrix to include factor variables in generalised linear regression models. With weighted effect coding, the effect for each category represents the deviation of that category from the weighted mean (which corresponds to the sample mean).

Mathematical Modeling and Evaluation of Performance Characteristics of a Hybrid Solar PV and Wind Energy System

open access: yesJournal of Applied Science and Engineering, 2022
Solar Photovoltaic (SPV) and wind energy are two major sources of renewable energy that are intermittent in nature. A hybrid system consisting of SPV and Wind Energy Conversion System (WECS) can meet the energy needs as either of the sources continues to
