A pseudo-DNS method for the simulation of incompressible fluid flows with instabilities at different scales
(Springer, 2019-07)
In this work, a new model for the analysis of incompressible fluid flows with massive instabilities at different scales is presented. It relies on resolving all the instabilities at all scales without any additional model, ...
Shape classification using complex network and Multi-scale Fractal Dimension
(ELSEVIER SCIENCE BV, 2010)
Shape provides one of the most relevant information about an object. This makes shape one of the most important visual attributes used to characterize objects. This paper introduces a novel approach for shape characterization, ...
Oriented Percolation in One-dimensional 1/vertical bar x-y vertical bar(2) Percolation Models
(SPRINGER, 2010)
We consider independent edge percolation models on Z, with edge occupation probabilities. We prove that oriented percolation occurs when beta > 1 provided p is chosen sufficiently close to 1, answering a question posed in ...
Model order reduction in computational multiscale fracture mechanics
(Trans Tech Publications, 2016-01)
Nowadays, the model order reduction techniques have become an intensive research field because of the increasing interest in the computational modeling of complex phenomena in multiphysic problems, and its consequent ...
Vector borne diseases on an urban environment: the effects of heterogeneity and human circulation
(Elsevier Science Bv, 2017-06)
We study the effect of human circulation and host/vector heterogeneities on the onset of epidemics of arboviruses. From a meta-population dynamics based on the classical Bailey-Dietz model, we derive a multi-group model ...
Bedforms-ATM, an open source software to analyze the scale-based hierarchies and dimensionality of natural bed forms
(Elsevier, 2018-06-30)
Bedforms-ATM (Bed forms analysis toolkit for multiscale modeling) is a software designed to hierarchize and quantify the dimensionality of natural bed forms fields. It comprises four modular applications, namely: (1) wavelet ...
A boundary element formulation to perform elastic analysis of heterogeneous microstructures
(2018-02-01)
A BEM formulation to perform elastic analysis of heterogeneous microstructures is proposed in the context of multi-scale analysis. The microstructure, also denoted as RVE (Representative Volume Element), is modeled as a ...
