Electric arcing due to contact interruption between the pantograph and overhead line in electrified railway networks is an important unwanted phenomenon. Arcing events are short-term power quality disturbances that produce significant electromagnetic both conducted radiated as well increased degradation on wire strip of pantograph. Early-stage detection can prevent further deterioration current...

Recent theory of capillary waves along the interface between two immiscible electrolytes is generalized to include the non-linear polarization of the double layer. The theory covers both the effects of the capillary waves on the double layer capacitance, as well as the effect of charging the interface on the amplitudes and spectrum of capillary waves. The theory explains major available experim...

BACKGROUND While coverage of a celebrity suicide in the mass media may trigger copycat suicides, evidence for the effect of media reports of non-prominent suicides is moderate. Diversification of current media may raise further doubts as to whether their influence on suicidal acts is still present. We examined whether widespread media coverage of a railway accident, in which several people were...

In this article, multiple-product PVRP with pickup and delivery that is used widely in goods distribution or other service companies, especially by railways, was introduced. A mathematical formulation was provided for this problem. Each product had a set of vehicles which could carry the product and pickup and delivery could simultaneously occur. To solve the problem, two meta-heuristic methods...

At present, there is a common effort to reduce the environmental effect of energy consumption. With this objective, transportation sector seeks improve emissions in all its modes. In particular, rail transport industry analysing various alternatives for non-electrified lines. These services are mainly carried out with diesel units. As an alternative fuel, present study use liquefied natural gas...

Pantograph arcing in electrified railway systems not only reduces the power collection quality of a locomotive but can also damage pantograph strips and overhead lines (OHLs). Most research detects pantograph-to-OHL arcs based on onboard voltage/current measurements, cameras, so on. The use data, though being cost-effective, rarely reflects arc locations along OHLs. This article develops an pos...

In some regions the exposure to railway noise is extremely concentrated, which may lead to high residential annoyance. Nonacoustical factors contribute to these reactions, but there is limited evidence on the interrelations between the nonacoustical factors that influence railway noise annoyance. The aims of the present study were (1) to examine exposure-response relationships between long-term...

Carbon pollution has become a sensitive topic across the globe in recent times. In Australia, incentive has been provided to industry in order to reduce carbon emissions in heavy polluting industries. The railway transportation system is one of the industries expected to reduce the emissions and contribute to a long term reduction strategy, although comparatively rail sector contributes much le...
