Ultrasonic sediment flux profiling with ACVP Technology: application to sediment-laden Boundary Layer flows

Sediment transport in geophysical boundary layer flows has relevance to a broad spectrum of sciences ranging from the physical and chemical, to the biological, ecological and geological. Advances in sediment transport modelling and prediction strongly suff ...

Reactivation of variably sealed joints and permeability enhancement in geothermal reservoir rocks

Alexandra Roma Larisa Kushnir, Michael Heap

Hydraulic stimulation of enhanced deep geothermal reservoirs commonly targets pre-existing joint networks with the goal of increasing reservoir permeability. Here, we study the permeability and strength of joint-free and jointed Buntsandstein sandstones fr ...

Metastable and localized Ising magnetism in alpha-CoV2O6 magnetization plateaus

Gregory Scott Tucker

alpha-CoV2O6 consists of j(eff) = 1/2 Ising to investigate the magnetic periodicity in the vicinity of these plateaus. We find these steps to be characterized by metastable and spatially short-range (xi similar to 10 angstrom) magnetic correlations with an ...

New perspectives for spatial planning in Switzerland: the role of ecosystem services

Rémi Jaligot

Spatial planning deals with the spatial expression of human activities in an integrated way to minimize their negative impacts on the natural and land systems. Rapid land use and land cover changes are important drivers of change of the benefits people der ...

Role of the electron-phonon coupling on the thermal boundary conductance of metal/diamond interfaces with nanometric interlayers

Ludger Weber, Maïté Blank, Gionata Schneider

Thermal boundary conductance (TBC) of the Ag/diamond and Au/diamond interfaces with a nanometer-thick interface layer of either nickel or molybdenum is measured by time domain thermoreflectance and modeled based on a 3-layer two-temperature model (3l-TTM). ...

Effect of Natural Weathering on Durability of Pultruded Glass Fiber-Reinforced Bridge and Building Structures

Thomas Keller, Anastasios Vassilopoulos, Julia De Castro San Roman Fest, Nikolaos Alexandros Theodorou

After 17 and 15years of use, respectively, a detailed inspection of a pedestrian bridge and a 5-story building structure composed of partly adhesively bonded pultruded glass fiber-reinforced polymer (GFRP) profiles was conducted accompanied by full-scale s ...

Mode I interlaminar fracture of carbon epoxy laminates: Effects of ply thickness

John Botsis, Thomas Gmür, Joël Cugnoni, Guillaume Frossard

In this work, the influence of ply thickness on strain energy release rate (ERR) in delamination of carbon epoxy laminates is addressed. Specimens with three ply thicknesses: 0.030, 0.075 and 0.150 mm are tested. While the ERR at onset of crack propagation ...

Espace sonore: une salle de concert. Réaffectation du centre de tri de la poste, Lausanne

Steve Cherpillod

Le projet propose une réaffectation du centre de tri de la poste, actuellement inoccupé, adjacent à la gare CFF de Lausanne. L'intervention vise à mettre en valeur les qualités du site en animant ce lieu resté somme toute marginal. En lui affectant une inf ...

Unconventional magnetization plateaus in a Shastry-Sutherland spin tube

Frédéric Mila, Salvatore Manmana, Jean-David Picon

Using density matrix renormalization group (DMRG) and perturbative continuous unitary transformations (PCUTs), we study the magnetization process in a magnetic field for all coupling strengths of a quasi-1D version of the 2D Shastry-Sutherland lattice, a f ...

Slow Time Behavior of the Semidiscrete Perona–Malik Scheme in One Dimension

Maria Colombo

We consider the long time behavior of the semidiscrete scheme for the Perona-Malik equation in one dimension. We prove that approximated solutions converge, in a slow time scale, to solutions of a limit problem. This limit problem evolves piecewise constan ...
