The unusual problem of upscaling isostaticity theory for granular matter
Raphael Blumenfeld
Jun 06, 2020
Abstract: Isostaticity theory (IT) provides stress field equations for marginally rigid packs of non-cohesive particles, interacting through hard-core forces. Its main advantage over strain-based theories is by closing the...

Organo-metal halide perovskite demonstrates a large potential for achieving highly efficient photovoltaic devices. The scaling-up process represents one of the major challenges to exploit this technology at the industrial level....
Robust numerical upscaling of elliptic multiscale problems at high contrast
We present a new approach to the numerical upscaling for elliptic problems with rough diffusion coefficient at high contrast. It is based on the localizable orthogonal decomposition of H 1 ${H^{1}}$ into the image and the...
