Abstract: Two critical speeds viz., the equilibrium speed and the overturning speed, are recognized to play an important role in defining operational and safety characteristics of railroads. An analysis ...

Abstract: A granular media known as iron impregnated sand (IIS), developed in the laboratory by impregnating iron on a quartz sand surface by a simple and easy process has proved more effective than iron oxide coated sand (IOCS). ...

Abstract: Most of the wear indices, used in the railroad industry for predicting wheel/rail wear, are functions of angle of attack between wheel and rail. Further, the wear problem has been studied in ...

Abstract: In this study, the municipal solid waste methane emission, energy, and global warming potential inventory for 2005–2030 is estimated at both national and state level for India using the Intergovernmental Panel on Climate ...

Abstract: Two new technologies have recently been developed that can help to solve some of the wheel rail contact problems. The first is a method of top of rail lubrication (TOR) or friction modification ...

Abstract: A field problem involving pumping of groundwater from a series of existing skimming wells to meet drinking water needs from a river flood plain is examined within a conceptual framework. A simplified hypothetical aquifer ...

Abstract: Flow through gate openings has been the subject of study by many investigators. Gates are often located on raised crests, as in the case of spillways. In such a situation, the flow is expected to behave similarly to flow ...

Abstract: In order to increase biogas production during winter months/cold climatic conditions, a self-sustained N-photovoltaic thermal and flat plate collector (PVT-FPC) hybrid active heating biogas plant has been analyzed in terms ...
