Performance assessment of road barriers in Indiana
… scenario.^ This study found that both the median and roadside barriers were effective in reducing crash costs, and that the former was the more effective of the two. Their main benefits were the reduction of cross-median head-on events for median barriers and reduction of non-cross-median …

Range of and relationships between physical and hydraulic properties of commonly available denitrifying bioreactor woodchips
… (permeameter method) and hand-measured woodchip median width were the only significant predictors of Ksat in a multiple linear regression model (Ksat = 0.081*DPperm + 0.048*Wmed; R2 = 0.48), however the model was limited by the small range in Ksat values resulting from high compaction. These …

Incidentalità in ambito urbano: studio del comportamento di guida in relazione alle caratteristiche geometriche dell’infrastruttura stradale
… traffic stream) and geometric design attributes (width of lines, type of median, length of tangent, presence of sidewalk, type of obstacle left-lateral). Under free flow conditions, three models were developed but only two were validated. The statistically significant variables include presence of …

Simulating organization of convective cloud fields and interactions with the surface
… Fine grid-spacing is necessary, as the median width of updraught cores mostly does not exceed 1000 m. We associate this influence with the dry air entrainment rate in the wake of rising parcels, and with how resolution and diffusion act on coherent structures in the flow. In 2D …

Confidence Intervals for Population Size in a Capture-Recapture Problem.
… and compared in terms of their expected interval width and exact coverage properties in two models. The new approach performs better than the Chapman in each model. Bayesian analysis also gives a different way to estimate population size.</p>
