Pitfalls in the spectral measurements of polarization-altering metasurfaces

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 ...

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 ...

Time calibration for the SciFi Tracker at SND@LHC using DESY testbeam data

Jennifer Maria Frieden

A Scintillating Fibre Tracker with timing information was developed by LPHE at EPFL. To evaluate its timing and tracking performance, a test beam campaign was organized at DESY in October 2019. By using this data, the different time delays and offsets that ...

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 ...

Robustness via curvature regularization, and vice versa

Pascal Frossard, Seyed Mohsen Moosavi Dezfooli, Alhussein Fawzi

State-of-the-art classifiers have been shown to be largely vulnerable to adversarial perturbations. One of the most effective strategies to improve robustness is adversarial training. In this paper, we investigate the effect of adversarial training on the ...

Pull-Out Behavior of CFRP Single-Strap Ground Anchors

Thomas Keller, Anastasios Vassilopoulos, Haifeng Fan

Pull-out experiments were performed on four carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in rock and soil. The CFRP tendons used in these anchors comprise a single-strap end on both ground and air sides. On the ground ...
