Control-oriented model for secondary effects of wake steering [PDF]

open access: yesWind Energy Science, 2021
This paper presents a model to incorporate the secondary effects of wake steering in large arrays of turbines. Previous models have focused on the aerodynamic interaction of wake steering between two turbines. The model proposed in this paper builds on

The Effects of Sleep Quality on Dream and Waking Emotions [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2021
Despite the increasing interest in sleep and dream-related processes of emotion regulation, their reflection into waking and dream emotional experience remains unclear. We have previously described a discontinuity between wakefulness and dreaming, with a prevalence of positive emotions in wakefulness and negative emotions during sleep.

Comparison of individual versus ensemble wind farm parameterizations inclusive of sub‐grid wakes for the WRF model

open access: yesWind Energy, 2022
Wind turbine wakes can be predicted somewhat accurately with mesoscale numerical models, such as the Weather Research and Forecast (WRF) model, via a wind farm parameterization (WFP) that treats the effects of the wakes, which are sub‐grid features, on ...

Data‐driven modelling of turbine wake interactions and flow resistance in large wind farms

open access: yesWind Energy, 2023
Turbine wake and local blockage effects are known to alter wind farm power production in two different ways: (1) by changing the wind speed locally in front of each turbine and (2) by changing the overall flow resistance in the farm and thus the so ...

Wake Interactions of Two Tandem Semisubmersible Floating Offshore Wind Turbines Based on FAST.Farm

open access: yesJournal of Marine Science and Engineering, 2022
Wake effects commonly exist in offshore wind farms, which will cause a 10–20% reduction of whole power production as well as a 5–15% increase of fatigue loading on the wind turbine main structures.

The Effect of Wind Energy on Microclimate: Lessons Learnt from a CFD Modelling Approach in the Case Study of Chios Island

open access: yesApplied Sciences, 2021
During the last three decades, rapid growth of wind energy has led to questions regarding the possible impacts of wind farms on local weather and microclimates.

Effects of Sleep and Wake on Oligodendrocytes and Their Precursors [PDF]

open access: yesThe Journal of Neuroscience, 2013
Previous studies of differential gene expression in sleep and wake pooled transcripts from all brain cells and showed that several genes expressed at higher levels during sleep are involved in the synthesis/maintenance of membranes in general and of myelin in particular, a surprising finding given the reported slow turnover of many myelin components ...

Reflected Protons in the Lunar Wake and Their Effects on Wake Potentials

open access: yesJournal of Geophysical Research: Space Physics, 2020
AbstractThe refilling of the lunar wake is facilitated by the wake ambipolar electric potential arising from the electron pressure gradient. Incident solar wind protons can be reflected by the lunar crustal magnetic fields and the lunar surface on the dayside and repicked up, entering the lunar wake due to their large gyroradii.

Effects of sleep and waking on the synaptic ultrastructure [PDF]

open access: yesPhilosophical Transactions of the Royal Society B: Biological Sciences, 2020
We summarize here several studies performed in our laboratory, mainly using serial block-face scanning electron microscopy (SBEM), to assess how sleep, spontaneous waking and short sleep deprivation affect the size and number of synapses in the cerebral cortex and hippocampus. With SBEM, we reconstructed thousands of cortical and hippocampal excitatory,

Wind Technologies for Wake Effect Performance in Windfarm Layout Based on Population-Based Optimization Algorithm

open access: yesEnergies, 2021
The focus of this study is under the auspices of China Steel Corporation, Taiwan, in carrying out the national energy policy of 2025 Non-Nuclear Home. Under this policy, an estimated 600 offshore wind turbines will be installed by 2025. In order to carry
