Optimizing Fueling Decisions for Locomotives in Railroad Networks

Michel Bierlaire, Prem Kumar

Even though rail transportation is one of the most fuel efficient forms of surface transportation, the cost of fuel constitutes one of the major categories of very high operating costs for railroad companies. In the United States, unlike in Europe, fueling ...

Exploring the physics of sediment transport in non-uniform super-critical ows using a large dataset of particle trajectories

Christophe Ancey, Joris Heyman

In this article, we present 10 experiments carried out in a steep, shallow water ume made of an erodible bed of natural, uniform gravel. We simultaneously recorded bed load particle motion, bed and water elevation using two high-speed cameras. Particle tra ...

Analysis of Ballast Transport in the Event of Overflowing of the Drainage System on High Speed Lines

Giovanni De Cesare, Tamara Ghilardi, Mona Jafarnejad Chaghooshi, Elena Battisacco

The transport of ballast caused by the overflowing of longitudinal drains is a prime example of the interactions between the railway track and its environment. In such conditions, water flowing from the platform, along with debris, may drag the ballast off ...

Transport mode choice in alpine resorts in Switzerland

Vincent Kaufmann, Emmanuel Pierre Jean Ravalet, Derek Pierre Christie

Mountain regions are under-represented in transport research, which tends to concentrate on urban areas. This study investigates transport mode choice in 22 locations in the Alps, using data from the 2010 Swiss transport micro-survey (hereafter: MRMT2010) ...

c-texture versus a-texture low pressure metalorganic chemical vapor deposition ZnO films: Lower resistivity despite smaller grain size

Christophe Ballif, Duncan Thomas Lindsay Alexander, Sylvain Nicolay, Monica Morales Masis, Laura Ding, Lorenzo Fanni, Arthur Brian Aebersold

Recently, it has been shown that it is possible to tune the morphology of zinc oxide films deposited by low-pressure metalorganic chemical vapor deposition (LP-MOCVD) while preserving good electrical conductivity. Here a closer look is taken at films depos ...
