Abstract: An evaluation of the utility of pilot reports (PIREPs) of weather for aviation forecasting product development is presented. Although PIREPs were never intended for quantitative use, this limitation has not prevented ...

Abstract: This paper first reviews the basic elements of the reproduction system in female mammals and indicates the adaptive significance of the cyclicity of structure and function always observed in ...

Abstract: This paper compares theoretical and experimental results on the friction-induced heating in thrust-loaded ball bearings at constant speed. Heat transfer and friction heat-generation models are ...

Abstract: Flexible pavement structural analysis for design usage must consider (as a minimum) multiple wheel/axle loading configurations, seasonal variations of material layer properties, and the nonlinear behavior of unbound ...

Abstract: Current vegetation models hold constant the dynamics of seasonal biospheric changes, neglecting annual variability. One of these features, the spring ?green wave? (onset of leafing or ?grean-up?) in midiatitudes, is an ...

Abstract: The effective use of pervious concrete in environmental site design requires consistent design procedures integrating the structural and material properties of the pervious concrete pavement with hydrologic performance of ...

Abstract: our convection-permitting Weather Research and Forecasting Model (WRF) forecasts were produced in an attempt to replicate the record-breaking rainfall across the Colorado Front Range between 1200 UTC 11 September and 1200 ...

Abstract: s high-resolution numerical weather prediction models are now commonplace, ?neighborhood? verification metrics are regularly employed to evaluate forecast quality. These neighborhood approaches relax the requirement that ...
