Owing to concern over the environment, there is much interest in renewable sources of energy, one of the most promising of which is wind power. Wind power is not yet a mature technology and one of the issues to be resolved is the most effective manner in which to regulate the wind turbines are posed by the different wind turbine configurations. A variety of control design tasks with differing o...
One of the most dynamical interplanetary phenomena of solar terrestrial physics is definitely the passage of solar wind streams near the Earth environment. In this work, we have identified the two types of high-speed solar wind streams using the spacecraft data during high amplitude days. The behaviour of high-speed solar wind streams during high amplitude anisotropic wave trains is investigate...
A processing system has been developed to meet increasing demands for detailed noise measurement of aircraft in wind tunnels. Phased arrays enable spatial and amplitude measurements of acoustic sources, including low signal-to-noise sources not measurable by conventional measurement techniques. The Microphone Array Phased Processing System (MAPPS) provides processing and visualization of acoust...
To facilitate the research of mobile robot based odor source localization (OSL) and evaluate different strategies for the OSL, numerical simulation of odor plume in indoor ventilated environments is addressed. On the basis of the FLUENT software package, the 3-D wind field of an indoor ventilated environment is calculated using the Reynolds average approach, where the real wind velocity measure...
The microwave polarimetric scattering from two-dimensional (2-D) wind fetchand water depth-limited nearshore sea surface is investigated by using the second-order small-slope approximation (SSA-II). The sea waves are simulated by taking into account the influences of fetch and depth. Based on this, the joint influence of fetch and depth on the normalized radar cross section (NRCS) of sea surfac...
The most favorable locations for wind farm were determined based on environmental landuse factors, wind resources and the layout of the electrical grid lines. In the study landuse map was prepared and updated by using Survey of India topographic sheet and ASTER satellite imagery in open source Quantum GIS & GRASS GIS software environment. Wind Power Density Layer was digitized by using Indian w...
Abstract: The prospect of China’s wind power industry is bright, but from the angle of investment, investment amount, operation and maintenance costs of wind power project are relatively high, at the same time, it is facing high policy risk and environment risk. Therefore, we should consider all kinds of risk factors to make appropriate risk management and control plan. Based on this, the paper...
Alaska's Prince William Sound (PWS) is a unique locale tending to have strong gap winds, especially in the winter season. To characterize and understand these strong surface winds, which have great impacts on the local marine and aviation activities, the surface wind retrieval from the Synthetic Aperture Radar data (SAR-wind) is combined with a numerical mesoscale model. Helped with the SAR-win...
At first glance, the 2015 General Election heralded a return to normality. According to its advocates, the single-member plurality electoral system enables the electorate to choose directly between alternative governments by ensuring that whichever party comes first in votes secures an overall majority in seats, even though it may have won much less than half the vote. For most of the post-war ...
Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena, for more than 10 years (2001–12) from the first large scale offshore wind farm in the world, Nysted Offshore Wind Farm, in the Danish western Baltic Sea (72× 2.3 MW turbines). The wind farm was brought into full operation in Dec...
