Abstract: The electrical characteristics of two active spring thunderstorms are reported. Simultaneous surface measurements of the sign and magnitude of the free charge on individual raindrops, the electric field and precipitation ...

Abstract: n accurate nonnegativity preserving limiter is presented for use with discontinuous Galerkin (DG) discretizations of scalar advection equations. The nonnegativity of the tracer field is preserved through the application ...

Abstract: The American Society of Civil Engineers and the National Society of Professional Engineers collaborate to bring attention to engineering issues at the federal government level in the ASCE program formally named “Leadership ...

Abstract: As a critical component of the national transportation network, bridges have received a lot of attention regarding their safety and condition state. Bridge superstructures begin to degrade after they are placed in service; ...

Abstract: Nonstructural vertical partitions and cladding can have a significant effect on the vibration serviceability of floor systems. A typical modern office building, consisting of steel–concrete composite floor systems, was ...

Abstract: With the existence of aging highway bridges within the U.S. transportation network, federal and local agencies typically encounter a wide assortment of maintenance issues ranging from cracking, spalls, delaminations, and ...

Abstract: It has been proposed in some recent publications that the cavitation damage rate decreases markedly in solids after long exposure to cavitation. It has also been proposed that this low rate ...

Abstract: he relationship between lateral spreading and mixing in stratified gravity currents is investigated by comparing laterally confined and unconfined currents in a series of laboratory experiments. The vertical turbulent ...
