Abstract: The evidence that variations in the sun itself are responsible for climate changes is substantial and hence it is frequently suggested that the sun's near-ultraviolet radiation is significantly variable. Whether or not ...

Abstract: Water is one of the most vital of all resources for human survival and thriving. Water is also an inherently shared resource, one that does not respect human boundaries—boundaries between persons, between communities, and ...

Abstract: A turbulent threedimensional wall jet with an exit Reynolds number of 250,000 was investigated using stereoscopic particle image velocimetry (PIV) in the nearfield region (x/D = 5). The proper orthogonal decomposition ...

Abstract: The corner wall jet is similar to the standard threedimensional wall jet with the exception that onehalf of the surface has been rotated counterclockwise by 90 deg. The corner wall jet is selected for study as the geometry ...

Abstract: The instantaneous turbulent velocity field in a three-dimensional wall jet was estimated from the fluctuating wall pressure using a spectral linear stochastic estimation technique. The wall jet ...

Abstract: In order to address how human foot movement causes particles to be resuspended from the floor, particle flow visualization and particle image velocimetry (PIV) measurements were performed on a ...

Abstract: A significant percentage of the bridges in North America were built after the Second World War. Most of them were originally designed for smaller vehicles, lighter loads, and a lower traffic volume than commonly experienced ...

Abstract: Tropical Storm Debra was tracked over a 31 h period in the Gulf of Mexico using the Wide Aperture Research Facility (WARF) high-frequency (HF) skywave radar in California. In contrast to the first WARF skywave radar tracking ...
