Large Eddy Simulation of Vertical Axis Wind Turbine Wakes

open access: yesEnergies, 2014
In this study, large eddy simulation (LES) is combined with a turbine model to investigate the wake behind a vertical-axis wind turbine (VAWT) in a three-dimensional turbulent flow.

Analytical Modeling of Wind Farms: A New Approach for Power Prediction

open access: yesEnergies, 2016
Wind farm power production is known to be strongly affected by turbine wake effects. The purpose of this study is to develop and test a new analytical model for the prediction of wind turbine wakes and the associated power losses in wind farms.

A Large-Eddy Simulation Study of Vertical Axis Wind Turbine Wakes in the Atmospheric Boundary Layer

open access: yesEnergies, 2016
In a future sustainable energy vision, in which diversified conversion of renewable energies is essential, vertical axis wind turbines (VAWTs) exhibit some potential as a reliable means of wind energy extraction alongside conventional horizontal axis ...

Wired: Wire-Aware Circuit Design [PDF]

open access: yes, 2005
Routing wires are dominant performance stoppers in deep sub-micron technologies, and there is an urgent need to take them into account already at higher levels of abstraction. However, the normal design flow gives the designer only limited control over the details of the lower levels, risking the quality of the final result.

Traffic savings through a cac procedure incorporating a fair bandwidth allocation policy for elastic services

open access: yesCommunications, 2004
We apply the max-min fairness policy (MMF) for elastic services with min and max bandwidth requirements (approximated MMF) not to a single link but to a whole connection-oriented network.

Nutritional evaluation of frass from black soldier fly larvae as potential feed ingredient for Pacific white shrimp, Litopenaeus vannamei

open access: yesAquaculture Reports, 2022
Frass is a by-product of the larval meal industry and is currently readily available and competitively priced relative to larva meal. In addition to generally high protein and fat content (21.6% and 6%, respectively), frass contains abundant nutrients ...
