average wind energy density at different heights are discussed.The results show that the average relative error of this method is 9.6%,which provides references for computing the wind power density so to estimate the variation of wind energy with height for the stations without gradient wind ...
Bridges have heights and weight limits. Tunnels often have restrictions on flammable or hazardous materials. Longer trucks have difficulty making tight turns. Highways often have a separate speed limit for trucks. Certain trucks may want to avoid roads that have steep gradients. ...
This work is intended as a contribution towards a possible harmonisation of methods and techniques, necessarily including surface roughness and atmospheric stability, aimed at extrapolating wind speed for wind energy purposes. Through the years, different methods have been used to this end, such as ...

heading and speed were randomized. All randomizations were performed by applying uniform distributions within the ranges defined by Metz et al. [14] as summarized inTable 6. The uniform distribution was chosen to ensure an even distribution of the bird positions in all degrees of freedom. The ...
