Multi-scale polarisation phenomena [PDF]

Light: Science & Applications, 2016
AbstractMulti-scale methods that separate different time or spatial scales are among the most powerful techniques in physics, especially in applications that study nonlinear systems with noise. When the time scales (noise and perturbation) are of the same order, the scales separation becomes impossible. Thus, the multi-scale approach has to be modified

Multi-scale modeling of gas-fluidized beds [PDF]

, 2006
Numerical models of gas-fluidized beds have become an important tool in the design and scale up of gas-solid chemical reactors. However, a single numerical model which includes the solid-solid and solid-fluid interaction in full detail is not feasible ...

Multi-scale modeling of dispersed gas-liquid two-phase flow [PDF]

, 2004
In this work the concept of multi-scale modeling is demonstrated. The idea of this approach is to use different levels of modeling, each developed to study phenomena at a certain length scale.

Multi-scale Multi-attention Network for Moiré Document Image Binarization

, 2021
In this paper, we propose a Multi-scale Multi-attention Network (MsMa-Net) to binarize document images contaminated by moiré patterns from camera-captured screens.

Effect of cohesion on local compaction and granulation of sheared soft granular materials

EPJ Web of Conferences, 2017
This paper results from an ongoing investigation of the effect of cohesion on the compaction of sheared soft wet granular materials. We compare dry non-cohesive and wet moderately-to-strongly cohesive soft almost frictionless granular materials and ...

Detrainment in deep convection

Geophysical Research Letters, 2012
This study explores the mechanisms that determine detrainment in deep cumulus convection. A set of 90 high‐resolution Large Eddy Simulations is used to systematically explore the sensitivity of continental deep convection to the relative humidity and ...

Optimized geothermal energy extraction from hot dry rocks using a horizontal well with different exploitation schemes

Geothermal Energy, 2023
In the foreseeable future, the geothermal exploitation from hot dry rocks (HDR) using a horizontal well will bear potential. Thus, in-depth studies should be conducted on the selection of injection-production scheme (IPS) and working fluid, design of ...

Multi-Scale attributed node embedding [PDF]

Journal of Complex Networks, 2021
Abstract We present network embedding algorithms that capture information about a node from the local distribution over node attributes around it, as observed over random walks following an approach similar to Skip-gram. Observations from neighbourhoods of different sizes are either pooled (AE) or encoded distinctly in a multi-scale ...
