Pitfalls in the spectral measurements of polarization-altering metasurfaces

Olivier Martin, Hsiang-Chu Wang

The optical characterization of metasurfaces and nanostructures that alter the polarization of light is tricky and can lead to unphysical results, such as reflectance beyond unity. We track the origin of such pitfalls to the response of some typical optica ...

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 ...

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

Eugen Brühwiler

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 ...

Mechanotaxis directs Pseudomonas aeruginosa twitching motility

Lorenzo Anton-Louis Talà, Alexandre Louis André Persat, Xavier Jean-Yves Pierrat, Jose Negrete Jr, Marco Julian Kühn, Joanne Netter Engel

The opportunistic pathogen Pseudomonas aeruginosa explores surfaces using twitching motility powered by retractile extracellu-lar filaments called type IV pili (T4P). Single cells twitch by sequen-tial T4P extension, attachment, and retraction. How single ...

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 ...

Towards non-invasive hybrid brain-computer interfaces: Framework, practice, clinical application and beyond

José del Rocio Millán Ruiz, Robert Leeb

In their early days, BCIs were only considered as control channel for end users with severe motor impairments such as people in the locked-in state. But, thanks to the multidisciplinary progress achieved over the last decade, the range of BCI applications ...

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 ...

Application of vertex and mass constraints in track-based alignment

Christophe Salzmann, Louis Nicolas, Géraldine Conti, Vincent Fave, Olivier Schneider, Frédéric Guillaume Dupertuis, Gerhard Raven, Matthew Needham, Maurizio Martinelli

The software alignment of planar tracking detectors using samples of charged particle trajectories may lead to global detector distortions that affect vertex and momentum resolution. We present an alignment procedure that constrains such distortions by mak ...

Comportement du ballast sous l'action du bourrage et du trafic ferroviaire

Chiara Paderno

The geometry of the railway track is degraded under traffic load, and must be maintained periodically. This degradation is due to the arrangement of ballast particles under loads and vibrations, which results into irreversible plastic settlements. Tamping ...
