Simulated heat storage in Canada's most northern lake: Towards a 3 dimensional model

This work focuses on heat fluxes and hydrodynamic of Ward Hunt Lake, Canada's most northern lake, as well as its response to climate variations. The project aims to implement a heat budget model, in order to improve our understanding of underlying mechanis ...

Analyzing Large-Scale Public Campaigns on Twitter

Karl Aberer, Philippe Cudré-Mauroux, Julia Proskurnia, Roman Prokofyev

Social media has become an important instrument for running various types of public campaigns and mobilizing people. Yet, the dynamics of public campaigns on social networking platforms still remain largely unexplored. In this paper, we present an in-depth ...

Asteroid Deflection Campaign Design Integrating Epistemic Uncertainties

Patricia Egger, Sung Wook Paek

Asteroid deflection entails multiple sources of epistemic uncertainties and stochastic uncertainties. Epistemic uncertainties can be reduced by replenishing incomplete information with a better means of observation, whereas stochastic uncertainties are inh ...

Effect of fiber orientation on the in-plane tensile response of UHPFRC reinforcement layers

Eugen Brühwiler, Emmanuel Denarié, Maléna Bastien Masse

The application on existing Reinforced Concrete (RC) slabs of cast-on site Ultra-High Performance Fiber Reinforced cement-based Composite UHPFRC) layers is a very efficient reinforcement technique, currently spreading. For the design of these tensile reinf ...

Enhanced formation of isoprene-derived organic aerosol in sulfur-rich power plant plumes during Southeast Nexus

Athanasios Nenes, Hairun Guo, André Welti

We investigate the effects of anthropogenic sulfate on secondary organic aerosol (SOA) formation from biogenic isoprene through airborne measurements in the southeastern United States as part of the Southeast Nexus (SENEX) field campaign. In a flight over ...

Occupants’ behaviour in energy simulation tools: lessons from a field monitoring campaign regarding lighting and shading control

Marilyne Andersen

Previous studies have shown that the choice of the behavioural model for the control of lighting and shading devices has important implications in the energy performance assessment of office buildings and directly influences the comparison of design altern ...

Hydrometeor classification from polarimetric radar measurements: a clustering approach

Alexis Berne, Devis Tuia, Jacopo Grazioli

A data-driven approach to the classification of hydrometeors from measurements collected with polarimetric weather radars is proposed. In a first step, the optimal number of hydrometeor classes (nopt) that can be reliably identified from a large set of pol ...

Correction of raindrop size distributions measured by Parsivel disdrometers, using a two-dimensional video disdrometer as a reference

Alexis Berne, Timothy Hugh Raupach

The raindrop size distribution (DSD) quantifies the microstructure of rainfall and is critical to studying precipitation processes. We present a method to improve the accuracy of DSD measurements from Parsivel (particle size and velocity) disdrometers, usi ...

Controls on the diurnal streamflow cycles in two subbasins of an alpine headwater catchment

Marc Parlange, Steven Vincent Weijs, Marc Calaf Bracons, Holly Jayne Oldroyd, Raphaël Mutzner

In high-altitude alpine catchments, diurnal streamflow cycles are typically dominated by snowmelt or ice melt. Evapotranspiration-induced diurnal streamflow cycles are less observed in these catchments but might happen simultaneously. During a field campai ...
