Biointerface dynamics – Multi scale modeling considerations
Colloids and Surfaces B: Biointerfaces, 2015Irreversible nature of matrix structural changes around the immobilized cell aggregates caused by cell expansion is considered within the Ca-alginate microbeads. It is related to various effects: (1) cell-bulk surface effects (cell-polymer mechanical interactions) and cell surface-polymer surface effects (cell-polymer electrostatic interactions) at the

Multi-scale observation models for motion estimation
2013 IEEE International Conference on Image Processing, 2013Multi-scale frameworks based on coarse-to-fine warping strategies are widely used in the state-of-the-art optical flow methods. While they allow the estimation of large motions and usually lead to a faster minimization, they can also create strong dependencies between the successive estimates at different scale levels, yielding sometimes the ...

If a mathematical model contains many different scales the computational cost for its numerical solution is very large. The smallest scale must be resolved over the distance of the largest scale. A huge number of unknowns are required and until recently many such problems could not be treated computationally.

Model Transformations in Multi Scale Modelling
2002Abstract Computer Aided Process Engineering (CAPE) requires computer based process models for most of its applications. Many of these applications require different attributes (accuracy, speed of solution, etc) of their models. For example, models that run in realtime sacrifice accuracy in exchange for speed, while offline applications do not need to

Turbulence, emergence and multi-scale modelling
Synthese, 2018The paper begins with a generic discussion of modelling, focusing on some of its practices and problems. I then move on to a philosophical discussion about emergence and multi-scale modelling; more specifically, the reasons why what looks like a promising strategy for dealing with emergence is sometimes incapable of delivering interesting results. This

A Data Model for Multi-scale Topographical Data
2008The lack of fully automated generalisation forces National Mapping Agencies to maintain topographical data sets at different map scales. For consistency between map scales, but also for supporting (future) automated generalisation processes, information on similarities and differences of the separate data sets should be identified and formalised.

Multi-scale Modeling of Gene Regulation of Morphogenesis
2012In this paper we demonstrate a spatio-temporal gene regulatory network for early gastrulation in the sea anemone Nematostella vectensis. We measure gene expression during early gastrulation using a gene expression quantification tool. We measure gene expression during early gastrulation when the embryo is more or less radial symmetrical and where there

Multi-scale Modelling of the Heart
2009A computational framework is presented for integrating the electrical, mechanical and biochemical functions of the heart. The gross anatomy as well as microstructural details are presented and the required imaging techniques. Active tension development of cardiac myocytes and the relation to cellular metabolism and electrophysiology are discussed in ...
