Minkowski Distance Based Pilot Protection for Tie Lines Between Offshore Wind Farms and MMC

Offshore wind farms (OWFs) with modular multilevel converter high-voltage dc (MMC-HVdc) have become an important form of renewable energy utilization. However, if a fault occurs at the tie line between the MMC and the OWF, the fault steady-state current at ...

Robust tunable acoustic impedance control on electroacoustic resonators for aircraft noise reduction

Maxime Volery

Air traffic noise emissions are responsible for a significant part of the overall environmental noise, especially in the vicinity of airports. Exposure to environmental noise is known to negatively impact health and to be associated with cardiovascular dis ...

Parameterizing snow saltation: the exponential decay of the mass flux profile and its relation to the saltation dynamics

Varun Sharma, Michael Lehning, Daniela Brito Melo, Armin Sigmund

Drifting snow events lead to snow redistribution and enhance snow sublimation. Taking into account the importance of snow sublimation to the correct prediction of the surface mass balance, a general consensus has emerged within the scientific community on ...

Automated identification of local contamination in remote atmospheric composition time series

Jian Wang, Julia Schmale, Andrea Baccarini, Ivo Fabio Beck, Hélène Paule Angot, Lubna Dada

A common challenge of atmospheric measurements in remote environments is to identify pollution from nearby activities that interfere with the purpose of the observations. Pollution, particularly from combustion, typically reveals itself in enhanced particl ...

Corona discharge actuator as an active sound absorber under normal and oblique incidence

Hervé Lissek, Stanislav Sergeev, Thomas Humbert

In the majority of active sound absorbing systems, a conventional electrodynamic loudspeaker is used as a controlled source. However, particular situations may require an actuator that is more resistant to harsh environments, adjustable in shape, and light ...

High-energy hadron colliders are designed to generate particle collisions within specialized detectors. A higher number of collisions is achieved with high-quality beams of low transverse emittances, meaning a small transverse cross-section, and high inten ...

EPFL2021

In environmental acoustics and in room acoustics, many surfaces exhibit extended-reaction (ER) behavior, i.e., their surface impedance varies with the angle of the incident sound wave. This paper presents a phenomenological method for modeling such angle d ...

A comparative study of indoor environmental quality in temporary emergency shelters

Patrick Bonzi

Extreme natural or man-made disasters are events caused by factors that injure, displace people and damage property. Victims of such events are often forced to live in temporary emergency shelters for prolonged time. It is therefore important to evaluate t ...
