Abstract: Approach slabs have been used by many state transportation agencies as a means to prevent settlement problems on embankments leading to a bridge. However, many problems have reduced the effectiveness and life of the approach ...

Abstract: Natural convection and passive heat rejection from two independent heat sources maintained at different temperatures (60°C and 100°C above ambient) on single circuit boards (FR4 and ...

Abstract: Mathematical and experimental errors cast doubt on the ice nucleus activity spectrum of falling dry ice pellets as reported by Fukuta et al. (1971). Preliminary laboratory studies have established that ice embryos or small ...

Abstract: A two-dimensional numerical model for the dynamics of surface ice transport and ice jam in rivers was developed and applied to the upper Niagara River. The model treats river ice dynamics as a two-layer system consisting ...

Abstract: This paper presents the results of model calibration and a parametric study of the ice-jamming processes in the Tonawanda Channel of the upper Niagara River using the one-dimensional river-ice model RICEN. The model is ...

Abstract: Winter operation of the New York Power Authority's and Ontario Hydro's hydropower generating stations on the Niagara River is affected by the possibility that ice jams might occur in the vicinity of the hydropower plant ...

Abstract: The power density of portable electronic devices continues to increase because packaging advances reduce their size even as features are added and enhanced. Designing thermal management systems ...

Abstract: To improve the thermal performance of phase change materials (PCMs), graphite nanofibers were embedded into a paraffin PCM. The thermal effects of graphite fiber loading levels (0–5wt%) and ...

Abstract: A novel design of a Lyman-alpha hygrometer for surface layer flux measurements is presented using a variable pathlength. The benefit of this device is the capability for in situ calibration during a field experiment with ...
