Abstract: Aircraft measurements of aerosol size distributions were used to calculate aerosol extinction coefficients at 12 flight altitudes over an urban and a rural site at Milwaukee. Analysis of vertical-horizontal cross sections ...

Abstract: Fundamental deformation and fracture behavior of fiber-reinforced metal-matrix composites under deformation processing conditions were determined using upset tests on rectangular specimens. Defects ...

Abstract: Turbulent convection is inherently a nonlocal phenomenon and a primary condition for a successful treatment of the convective boundary layer is a reliable model of nonlocality. In the dynamic equations governing the ...

Abstract: To eliminate a grade crossing of rail lines, the Port of Vancouver USA, in Vancouver, Washington, elected to route a new line to its entrance beneath a bridge carrying a major north–south line. The new line would be well ...

Abstract: Lunar soil consists of dry silty sand. Observations and measurements conducted during Surveyor, Apollo, and Luna missions indicated that the lunar soil is unusually cohesive. This is attributable to the fact that thick ...

Abstract: The goal of this paper is to derive the equation for the turbulence dissipation rate ε for a shear-driven flow. In 1961, Davydov used a one-point closure model to derive the ε equation from first principles but the final ...

Abstract: Determination of Mars soil mechanical properties will improve future lander mission success and provide narrower constraints for geomorphological modeling. A soil mechanics investigation was conducted wherein soil mechanical ...

Abstract: Ocean mixing processes have traditionally been formulated using one-point turbulence closure models, specifically the Mellor and Yamada (MY) models, which were pioneered in geophysics using 1980 state-of-the-art turbulence ...

Abstract: A Reynolds stress?based model is used to derive algebraic expressions for the vertical diffusivities Kα(α = m, h, s) for momentum, heat, and salt. The diffusivities are expressed as Kα(R?, N, RiT, ?)in terms of the density ...

Abstract: A methodology for obtaining estimates of the spatial distribution of fog water volume collected by a tree canopy in complex terrain is described. The method includes assumptions about the shape and spacing of the trees, ...
