Mapping Spatial Distribution of Pores in an Additively Manufactured Gold Alloy Using Neutron Microtomography
Roland Logé, Jamasp Jhabvala, Markus Strobl, Hossein Ghasemi Tabasi, Michaël Meyer
A crucial criterion for the quality of the additively manufactured parts is the porosity content for achieving an acceptable final relative density. In addition, for jewelry applications, visible pores are unacceptable at or in the vicinity of the surface. ...
2021Geotechnical and environmental performance of retaining structures in unsaturated soils
Presently, environmental issues are considered as critical aspects concerning the market competitiveness in the building and construction sector. However, the construction sector is regarded as one of the main areas contributing to CO2 emissions and resour ...
EPFL2020Impact of Mineralogical Composition on Geotechnical Properties of Opalinus Clay
Lyesse Laloui, Alessio Ferrari, Eleonora Crisci
Opalinus Clay is the selected host geomaterial for the construction of underground geological disposals for radioactive waste in Switzerland. The formation has been studied in several sites, i.e. the Mont Terri laboratory, and several boreholes in the nort ...
2019Anisotropic behaviour of Opalinus Clay through consolidated and drained triaxial testing in saturated conditions
Lyesse Laloui, Alessio Ferrari, Valentina Favero
This paper investigates the anisotropic hydro-mechanical behaviour of Opalinus Clay shale, the host material currently being considered for the construction of a nuclear waste repository in Switzerland. Consolidated and drained triaxial tests on Opalinus C ...
2018A Miniaturized Biaxial Deformation Rig for in Situ Mechanical Testing
Helena Van Swygenhoven, Steven Van Petegem
A novel miniaturized biaxial deformation rig is presented. It allows one to apply in-plane biaxial stress states with arbitrary stress ratios and to perform strain path changes on thin-sheet metals. The device is optimized for in situ usage inside a scanni ...
Springer2017The role of mass-transport deposits and turbidites in shaping modern lacustrine deepwater channels
Subaquatic canyons are an important pathway for sediment transport into oceanic and lacustrine basins. Understanding the mechanisms governing their geomorphological evolution is a key to predict the sediment distribution patterns through these sediment con ...
Elsevier2016Robust optimization for strategic energy planning
Michel Bierlaire, François Maréchal, Stefano Moret
Long-term planning for energy systems is often based on deterministic economic optimization and forecasts of fuel prices.When fuel price evolution is underestimated, the consequence is a low penetration of renewables and more efficient technologies in favo ...
2016Temporal evolution of crack propagation propensity in snow in relation to slab and weak layer properties
Johan Alexandre Philippe Gaume, Jürg Schweizer, Alec van Herwijnen
If a weak snow layer below a cohesive slab is present in the snow cover, unstable snow conditions can prevail for days or even weeks. We monitored the temporal evolution of a weak layer of faceted crystals as well as the overlaying slab layers at the locat ...
2016The Impact of Uncertainty in National Energy Planning
Michel Bierlaire, François Maréchal, Stefano Moret, Victor Codina Gironès
Concerns related to climate change and security of energy supply are pushing various countries to define strategic energy plans. Strategic energy planning for national energy systems involves investment decisions (selection and sizing) for energy conversio ...
2016Pre-clinical Evaluation of a Cyanine-Based SPECT Probe for Multimodal Tumor Necrosis Imaging
Recently we showed that a number of carboxylated near-infrared fluorescent (NIRF) cyanine dyes possess strong necrosis avid properties in vitro as well as in different mouse models of spontaneous and therapy-induced tumor necrosis, indicating their potenti ...
