Reducing false wake-up in contention-based wake-up control of wireless LANs [PDF]
This paper studies the potential problem and performance when tightly integrating a low power wake-up radio (WuR) and a power-hungry wireless LAN (WLAN) module for energy efficient channel access.

Sensitivity of Wake Modelling Setups
Abstract Engineering wake modelling with single turbine wake models and wake superposition models (SupModel) requires the choice of two crucial settings: the type of wake superposition and the wake expansion rate parameter. Based on offshore wind farm measurements, the appropriate tuning of such wake modelling setups with respect to wind

A New Streamwise Scaling for Wind Turbine Wake Modeling in the Atmospheric Boundary Layer
In this study, we aim to investigate if there is a scaling of the streamwise distance from a wind turbine that leads to a collapse of the mean wake velocity deficit under different ambient turbulence levels.

An Aero-acoustic Noise Distribution Prediction Methodology for Offshore Wind Farms
Recently attention has been paid to wind farm noise due to its negative health impact, not only on human beings, but also to marine and terrestrial organisms. The current work proposes a numerical methodology to generate a numerical noise map for a given

Coupled wake boundary layer model of wind-farms [PDF]
We present and test the coupled wake boundary layer (CWBL) model that describes the distribution of the power output in a wind-farm. The model couples the traditional, industry-standard wake model approach with a "top-down" model for the overall wind ...

Clarification of influences of inflow conditions on wake of horizontal axis wind turbine
In recent years, wind turbines are introduced in wind farms in which some wind turbines are concentrated. When wind turbines are built in contiguity with each other in wind farms, the flow passing through a wind turbine, which is called wake, may flow ...

A physical wind‐turbine wake growth model under different stratified atmospheric conditions
The wind‐turbine wake growth is crucial for wake assessment. At present, it can only be determined empirically, which is the primary source of prediction errors in the analytical wake model, and a physically‐based method is urgently needed. Recently, the

A Fast-Slow Analysis of the Dynamics of REM Sleep
Waking and sleep states are regulated by the coordinated activity of a number of neuronal population in the brainstem and hypothalamus whose synaptic interactions compose a sleep-wake regulatory network.

Study of Generalized Interaction Wake Models Systems with ELM Variation for Off-Shore Wind Farms
This paper reports a novel frandsen generalized wake model and its variation model-frandsen generalized normal distribution wake model for off-shore wind farms. Two different new wake models in off-shore wind farms have been studied comparatively.
