Elastoplastic description of sudden failure in athermal amorphous materials during quasistatic loading

Matthieu Wyart, Thomas Willem Jan de Geus, Marko Popovic

The response of amorphous materials to an applied strain can be continuous or instead discontinuous if the initial configuration is very stable. We study theoretically how such a stress drop emerges as the system's initial stability is increased. We show t ...

Multi-scale modeling of the urban meteorology: Integration of a new canopy model in the WRF model

Dasaraden Mauree, Alain Clappier

Urban parametrizations have been recently developed and integrated in mesoscale meteorological models for a better reproduction of urban heat islands and to compute building energy consumption. The objective of the present study is to evaluate the value of ...

Long-term path prediction in urban scenarios using circular distributions

Alexandre Massoud Alahi

Human ability to foresee the near future plays a key role in everyone's life to prevent potentially dangerous situations. To be able to make predictions is crucial when people have to interact with the surrounding environment. Modeling such capability can ...

Spatial variability in snow precipitation and accumulation in COSMO–WRF simulations and radar estimations over complex terrain

Varun Sharma, Michael Lehning, Alexis Berne, Franziska Gerber, Marco Gabella, Nikola Besic, Urs Martin Germann

Snow distribution in complex alpine terrain and its evolution in the future climate is important in a variety of applications including hydropower, avalanche forecasting and freshwater resources. However, it is still challenging to quantitatively forecast ...

Impact of the microstructure model on coupled simulation of drying and accelerated carbonation

Fabien Jacques Michel Georget

During carbonation, the microstructure of a cement paste is strongly modified, which induces a dynamic feedback loop impacting the global advancement of the reaction. In this study, we investigate the effect of the microstructure model on simulations of ac ...

Allocation of Frequency Control Reserve from Aggregated Resources of Active Distribution Systems

Fabrizio Sossan, Mokhtar Bozorg, Mohsen Kalantar Neyestanaki

This paper addresses the allocation of frequency control services (FCSs) from aggregated resources of active distribution systems (ARADSs) for balancing the transmission system while considering credible contingencies as well as forecast error of loads and ...

Snowpack runoff formation processes during rain-on-snow events

Sebastian Würzer

Rain-on-snow (ROS) events cause repeated flooding in many mountainous regions with a seasonal snow cover. The complex interaction of processes across spatial scales makes it difficult to accurately predict the effect of snow cover on runoff formation for a ...

Reactive transport modelling of cement paste leaching in brines

Fabien Jacques Michel Georget

We propose and analyse a unified reactive transport model for leaching of cement paste in brines, with and without CO2. We investigate the impact of the boundary conditions on the rate of propagation of the reaction. In agreement with experiments, we obser ...

Adaptive Quantization for Deep Neural Network

Pascal Frossard, Seyed Mohsen Moosavi Dezfooli, Yiren Zhou

In recent years Deep Neural Networks (DNNs) have been rapidly developed in various applications, together with increasingly complex architectures. The performance gain of these DNNs generally comes with high computational costs and large memory consumption ...

Adaptive isogeometric methods with hierarchical splines: Optimality and convergence rates

Annalisa Buffa

We consider an adaptive isogeometric method (AIGM) based on (truncated) hierarchical B-splines and continue the study of its numerical properties. We prove that our AIGM is optimal in the sense that delivers optimal convergence rates as soon as the solutio ...
