Abstract: In order to take full advantage of the high energy density available in methanol fuel, one must use high concentration methanol in direct methanol fuel cells (DMFCs). However, this causes ...

Abstract: To obtain more in-depth knowledge about the microscopic process during laser sintering, phase change processes including melting, evaporation, and resolidification during the irradiation of femtosecond ...

Abstract: Urban flood inundation is spatially uncertain. To quantify this uncertainty, it is necessary to explore the spatial probability of urban flood inundation in different return periods. In this study, an urban flood spatial ...

Abstract: Ultrashort laser pulses can be generated in the form of a pulse train. In this paper, the ultrafast phase change processes of a 1 μm free-standing gold film irradiated by femtosecond laser ...

Abstract: A new median treatment technique using longitudinal channelizers has been used in Florida as an alternative to the traditional permanent concrete barrier. However, the effects of the new technique on roadway safety and its ...

Abstract: The discrete element method (DEM) was used to investigate the coefficient of earth pressure at rest, K, of granular soils. The results indicate that K decreases as the void ratio decreases and the vertical stress increases. ...

Abstract: In aerospace load simulation loading systems, due to the coupling between the loading system and the system under testing, surplus forces and poor loading accuracies remain to be key issues. To solve this, this paper ...
