Exploring and machine learning structural instabilities in 2D materials
npj Computational Materials, 2023 We address the problem of predicting the zero-temperature dynamical stability (DS) of a periodic crystal without computing its full phonon band structure.

Scale invariance without scale selection [PDF]
2008 IEEE Conference on Computer Vision and Pattern Recognition, 2008 In this work we construct scale invariant descriptors (SIDs) without requiring the estimation of image scale; we thereby avoid scale selection which is often unreliable. Our starting point is a combination of log-polar sampling and spatially-varying smoothing that converts image scalings and rotations into translations.

Neck growth kinetics during polymer sintering for powder-based processes [PDF]
EPJ Web of Conferences, 2021 To prevent texture defects in powder-based processes, the sintering time needs to be adjusted such that a certain amount of coalescence is achieved. However, predicting the required sintering time is extremely challenging to assess in materials such as ...

Advances and visions in large-scale hydrological modelling : findings from the 11th Workshop on Large-Scale Hydrological Modelling [PDF]
, 2008 Large-scale hydrological modelling has become increasingly wide-spread during the last decade. An annual workshop series on large-scale hydrological modelling has provided, since 1997, a forum to the German-speaking community for discussing recent ...

Steady state rheology from homogeneous and locally averaged simple shear simulations
EPJ Web of Conferences, 2017 Granular materials and particulate matter are ubiquitous in our daily life and they display interesting bulk behaviors from static to dynamic, solid to fluid or gas like states, or even all these states together. To understand how the micro structure and

Scaling and scale breaking in polyelectrolytes
The Journal of Chemical Physics, 1996 We consider the thermodynamics of a uniformly charged polyelectrolyte with harmonic bonds. For such a system there is at high temperatures an approximate scaling of global properties like the end-to-end distance and the interaction energy with the chain length divided by the temperature.
