Influence of sun cups on surface albedo of wet Alpine snowpack

Loïc Marcel Louis Brouet, Michael Lehning

In high elevation Alpine areas, characterised by high snow accumulation and radiation-driven melt processes, the formation of peculiar ablation features called sun cups can be observed. Sun cups likely influence the energy and mass balance of the wet snowp ...

Automated neuron tracking inside moving and deforming C. elegans using deep learning and targeted augmentation

Ariane Andrée Marie Delrocq, Sahand Jamal Rahi

Reading out neuronal activity from three-dimensional (3D) functional imaging requires segmenting and tracking individual neurons. This is challenging in behaving animals if the brain moves and deforms. The traditional approach is to train a convolutional n ...

On Triangulation as a Form of Self-Supervision for 3D Human Pose Estimation

Pascal Fua, Sina Honari, Leonardo Citraro, Soumava Kumar Roy

Supervised approaches to 3D pose estimation from single images are remarkably effective when labeled data is abundant. However, as the acquisition of ground-truth 3D labels is labor intensive and time consuming, recent attention has shifted towards semi- a ...

Black carbon and dust in the Third Pole glaciers: revaluated concentrations, mass absorption cross-sections and contributions to glacier ablation

Julia Schmale

In snow and ice, light-absorbing particles (LAPs), such as black carbon (BC) and dust, accelerate the melting of Third Pole glaciers (TPGs). In this study, we revaluated LAP concentrations in the snow pits of TPGs (SP-TPGs), measured LAP mass absorption cr ...

How Forward-Scattering Snow and Terrain Change the Alpine Radiation Balance With Application to Solar Panels

Michael Lehning, Annelen Kahl

Rough terrain in mid- and high latitudes is often covered with highly reflective snow, giving rise to a very complex transfer of incident sunlight. In order to simplify the radiative transfer in weather and climate models, snow is generally treated as an i ...

Improved Near-Surface Continental Climate in IPSL-CM6A-LR by Combined Evolutions of Atmospheric and Land Surface Physics

Etienne Gabriel Henri Vignon

This work is motivated by the identification of the land-atmosphere interactions as one of the key sources of uncertainty in climate change simulations. It documents new developments in related processes, namely, boundary layer/convection/clouds parameteri ...

Simple and easily controllable parabolic-shaped microlenses printed on polymeric mesas

Jürgen Brugger, Cristina Martin Olmos, Joo Yeon Kim

A simple and easy shape-controllable approach is demonstrated for the fabrication of parabolic-shaped polymer microlenses (mu-lenses), which are widely used in bio-imaging systems such as microfluidic and lab-on-a-chip systems for improving the image quali ...

Dynamic wetting in pressure-infiltration of ceramic particle preforms by molten metal

Gionata Schneider

This thesis investigates the interaction between mechanically induced flow of a liquid metal into a porous solid, and kinetic effects at the triple line. The approach is experimental and focuses on metal-ceramic systems for which the literature gives value ...

Relationship between high daily erythemal UV doses, total ozone, surface albedo and cloudiness: An analysis of 30 years of data from Switzerland and Austria

This work investigates the occurrence frequency of days with high erythemal UV doses at three stations in Switzerland and Austria (Davos, Hoher Sonnblick and Vienna) for the time period 1974-2003. While several earlier studies have reported on increases in ...

SPH High-Performance Computing simulations of rigid solids impacting the free-surface of water

François Avellan, Pierre Maruzewski

Numerical simulations of water entries based on a three-dimensional parallelized Smoothed Particle Hydrodynamics (SPH) model developed by Ecole Centrale Nantes are presented. The aim of the paper is to show how such SPH simulations of complex 3D problems i ...

Retrieving multiple light sources in the presence of specular reflections and texture

Pascal Fua

Recovering multiple point light sources from a sparse set of photographs in which objects of unknown texture can move is challenging. This is because both diffuse and specular reflections appear to slide across surfaces, which is a well known physical fact ...

Modeling the performance of cool pavements and the effect of their aging on outdoor surface and air temperatures

Flourentzos Flourentzou

Aiming at the improvement of a dense urban area's microclimatic conditions, this study examines by simulation means, the application of highly reflective materials as a mitigation strategy. However, as significant albedo changes may occur due to weathering ...

Sorption of hydrophobic organic compounds (HOC) in rapeseed oil bodies

Ian William Marison, Julien Boucher

Oil-bodies are minute plant organelles (0.5-2.0 mu m diameter) consisting of an oil core surrounded by a phospholipid monolayer/proteinaceous membrane. Oil-bodies have been isolated from rapeseed seeds and demonstrated to constitute a novel type of micro-c ...

Interface-fitted moving mesh method for axisymmetric two-phase flow in microchannels

John Richard Thome, Gustavo Rabello Dos Anjos, Erik Gros

A boundary-fitted moving mesh scheme is presented for the simulation of two-phase flow in two-dimensional and axisymmetric geometries. The incompressible Navier-Stokes equations are solved using the finite element method, and the mini element is used to sa ...

Dynamics of methane dissociation on transition metals

Rainer Beck

One of the many contributions of Harold Winters to surface science was his pioneering ultrahigh vacuum study on the kinetics of the technologically important dissociation of CH4 on transition metals in the 1970s. He observed a dramatic activation of the di ...

Hydro-mechanical analysis of volcanic ash slopes during rainfall

Lyesse Laloui, Alessio Ferrari, John Eichenberger, Chao Li

Rainfall-induced landslides in volcanic ashes represent a major natural hazard in many regions around the world. Due to their loose structure, volcanic ash slopes are prone to rainfall-induced landslides. The paper presents a continuum modelling approach f ...

Nitrogen, Phosphorus, and Sulfur Co-Doped Hollow Carbon Shell as Superior Metal-Free Catalyst for Selective Oxidation of Aromatic Alkanes

Shuliang Yang, Li Peng

Metal-free heteroatom-doped carbocatalysts with a high surface area are desirable for catalytic reactions. In this study, we found an efficient strategy to prepare nitrogen, phosphorus, and sulfur co-doped hollow carbon shells (denote as NPS-HCS) with a su ...
