Precise lateral jet interaction models are required for missiles’ blending control strategies. Because of the complicated flow field, the interaction models are multivariable, complex and coupled. Traditional aerodynamics coefficients model identification used Maximum-likelihood estimation to adjust the parameters of the postulation model, but it is not good at dealing with complex nonlinear mo...

Abstract To study the difference in wind-induced response of transmission tower caused by downburst and well-conditioned wind field, this paper uses harmonic superposition method to simulate field field. The responses under two farms are obtained compared through analysis. fields on quite different, can cause a larger response.

We describe a large sensor field whose mission is to protect coastal waters by detecting objects like submarines. The system is buoy-based and distributed over a littoral area. The opportunities for detection are short and intermittent and the signal to noise ratio is low. The topology of the field changes with time due to currents, wind, tides and storms. The field has a number of gateway node...

-Wind energy has been used for navigation and agriculture. Recently, wind energy is given a lot of attention because of the focus on renewable energy. Wind energy growth in Asia is currently on the rise. Both India and China are leading with more installed capacity and manufacturing facilities. In Malaysia, wind energy conversion is also given a serious consideration. The potential for wind ene...

This paper presents a short-term wind turbine (WT) outage model based on the data collected from a wind farm supervisory control and data acquisition (SCADA) system. Neural networks (NNs) are used to establish prediction models of the WT condition parameters that are dependent on environmental conditions such as ambient temperature and wind speed. The prediction error distributions are discusse...

The stable boundary layer (SBL) is a stably stratified atmospheric layer that usually forms in the night over land when the earth cools as a result of a net loss of radiation[7]. The wind field characteristics in SBL distinctly differ from those in unstable boundary layer that forms in the daytime. Figures 1(a) and 1(b) show how the longitudinal wind speed and the wind direction change with the...

Increasing load of air pollution in urban environment emphasises the need for detailed evaluation of wind characteristics that significantly affect the air quality of urban areas, especially, in large agglomerations. This paper includes analysis of urban wind cli-matology and estimation of wind profiles based on measurements of the new urban 5 climate station located at the E ¨ otvös University...

Synthetic Aperture Radar (SAR) is a useful and efficient tool for providing high-resolution images from sea surface wind fields. Wind field analysis based on SAR image descriptors makes the estimation of wind direction and speed possible. This is very useful for applications and Studies such as oil spills, waves, ocean circulation, marine meteorology and the coupling of oceanic and atmospheric ...

Atmospheric wind field is 3-dimensional and variable over time and space. Doppler radar measures one component of the wind vector, ie. the radar radial component. For complete description of the wind field simultaneous measurements should be made with three Doppler radars. Usually only one radar is available and the availability of the other two radars is compencated by simplifying assumptions ...

Wind disturbance can create large forest blowdowns, which greatly reduces live biomass and adds uncertainty to the strength of the Amazon carbon sink. Observational studies from within the central Amazon have quantified blowdown size and estimated total mortality but have not determined which trees are most likely to die from a catastrophic wind disturbance. Also, the impact of spatial dependen...
