Enhancement of riveted steel bridges by adding a trough in UHPFRC acting in composite action

Riveted railway bridges are commonly considered as being “old”, having fatigue damage and are therefore replaced. While this practice should be by now obsolete by using novel engineering methods like structural monitoring, prolongation of the service durat ...

Renewal of a fixed railway track using UHPFRC - first use worldwide of UHPFRC in rail track construction, part 1

Eugen Brühwiler, Antonina Hochuli

This two-part article reports on the renewal and adaptation of the fixed railway track in the heavily frequented underground train station at Zurich Airport. The fixed track built in 1980 had reached the service duration predicted by the system provider an ...

Mask to identify polluted periods during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

Aerosol and trace gas measurements are strongly affected by the ship exhaust and other human activities (e.g., helicopter flights). Therefore, it is important to discriminate between clean and polluted periods. This mask provides an indication of clean per ...

Model-based economic analysis of electrification in railway - Understanding the impact of track, operations, and uncertainties

Michel Bierlaire, Nikola Obrenovic, Florian Mueller

This paper presents results on the impact of different tracks on the economic viability of track electrification for regional railway. Since regional railway still heavily relies on pollutive diesel propulsion systems, track electrification can be key to r ...

Integrated maintenance model for heavy haul tracks

José João Pires De Oliveira Filho

Due to the accumulation of traffic, the railway components are affected by the induced stresses. As a result, the geometry of the railways is degraded over time. The degradation occurs either through the partial loss of the track's geometry or through the ...

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 ...

Flexible triangular formation keeping of marine robotic vehicles using range measurements

Colin Neil Jones, Jorge Miguel Dias Almeida Rodrigues Soares, Francisco Fernandes Castro Rego

This paper addresses the problem of keeping an autonomous marine vehicle in a moving triangular formation by regulating its position with respect to two leader vehicles. The follower vehicle has no prior knowledge of the path described by the leaders but h ...

Development of a Fast Cluster Finding self-seeded trigger demonstrator

Hui Wang

The ABC 130 chip developed for the high luminosity LHC(HL-LHC) upgrade of the ATLAS silicon strip tracker implements a Fast Cluster Finder (FCF). The FCF is capable of reading out certain track cluster information serially with a clock rate up to 640 MHz, ...
