Adhesive wear mechanisms in the presence of weak interfaces: Insights from an amorphous model system

Engineering wear models are generally empirical and lack connections to the physical processes of debris generation at the nanoscale to microscale. Here, we thus analyze wear particle formation for sliding interfaces in dry contact with full and reduced ad ...

Exploration of spatial structures made from reused elements and the design of optimal kits-of-parts

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting

Reuse reduces raw material use, waste generation and energy consumption caused by building construction. A substantial share of these impacts is contributed by load-bearing systems be-cause of their mass- and energy-intensive production process. Therefore, ...

Comparative analysis of transmittance measurement geometries and apparatus

Sabine Süsstrunk, Marjan Shahpaski

The accurate measurement of reflectance and transmittance properties of materials is essential in the printing and display industries in order to ensure precise color reproduction. In comparison with reflectance measurement, where the impact of different g ...

Adhesive wear mechanisms in the presence of weak interfaces

Jean-François Molinari, Tobias Brink

Despite the relevance of wear in many engineering applications, our understanding of the connection between mechanisms at the nanoscale and the observed wear rates of contacting parts at the macroscale remains limited. Recent work in our group has therefor ...

Optimum Truss Design with Reused Stock Elements

Corentin Jean Dominique Fivet, Gennaro Senatore, Jan Friedrich Georg Brütting, Joseph Jean François Desruelle

This paper proposes the application of optimization techniques to design reticular structures made from a stock of reused elements. Still little explored, the reuse of structural components over multiple service lives has the potential to reduce the enviro ...

Structure-Preserving Reduced Basis Methods for Hamiltonian Systems with a Nonlinear Poisson Structure

Jan Sickmann Hesthaven, Cecilia Pagliantini

We develop structure-preserving reduced basis methods for a large class of problems by resorting to their semi-discrete formulation as Hamiltonian dynamical systems. In this perspective, the phase space is naturally endowed with a Poisson manifold structur ...

Structure-Preserving Reduced Basis Methods for Hamiltonian Systems with a State-dependent Poisson Structure

Jan Sickmann Hesthaven, Cecilia Pagliantini

We develop structure-preserving reduced basis methods for a large class of nondissipative problems by resorting to their formulation as Hamiltonian dynamical systems. With this perspective, the phase space is naturally endowed with a Poisson manifold struc ...

pHARDI: accelerated reconstruction toolkit for estimating the white matter fiber geometry from diffusion MRI data

Erick Jorge Canales Rodriguez

Diffusion magnetic resonance imaging is a non-invasive technique capable of quantifying the diffusion process of water molecules in living biological tissues. Its main application is the study of the local geometry and wiring pattern of the human brain whi ...

Effect of plasma geometry on divertor heat flux spreading: MONALISA simulations and experimental results from TCV

Holger Reimerdes, Benoît Labit, Christian Gabriel Theiler, Federico Nespoli, Roberto Maurizio

Safe ITER operations will rely on power spreading to keep the peak heat flux within divertor material constraints. A solid understanding and parameterization of heat flux profiles is therefore mandatory. This paper focuses on the impact of plasma geometry ...
