Abstract: In this research, electrochemical impedance spectroscopy is employed to monitor the resistance of a fuel cell during operation with different operating conditions and different materials for the ...

Abstract: In cold regions, snow and ice cause serious safety problems to the transportation system. South central Alaska, particularly Anchorage, is susceptible to a number of icing events resulting from frequent freeze/thaw cycles ...

Abstract: Based on metacartography, this study establishes a model to convert the time distance of taking light rail to the spatial distance in meters. On this basis, this study uses the spatial transformation method of geographic ...
