Naar een vrijwillige opschaling van de lokale politie Universiteit Gent
Pleidooi voor een opschaling van het lokale woonbeleid in Vlaanderen KU Leuven
Drawing on a mixed method study in the province of West Flanders, we plead in this article for an upscaling of housing policies in Flanders. Based on a quantitative analysis of migration data for the whole province in 2009 and 2010, we make it obvious, first, that housing dynamics do not take place at the scale of individual towns and municipalities, but at the larger scale of regional housing markets. Based on a qualitative analysis of ...

Perspectives for DNA adductomics in large-scale exposomics : upscaling sample preparation and preprocessing data Universiteit Gent
Space-time upscaling of reactive transport in porous media Universiteit Hasselt
Reactive transport in saturated/unsaturated porous media is numerically upscaled to the space-time scale of a hypothetical measurement through coarse-grained space-time (CGST) averages. The reactive transport is modeled at the fine-grained Darcy scale by the actual number of molecules involved in reactions which undergo advective and diffusive movements described by global random walk (GRW) simulations. The CGST averages verify identities ...
Effect of feed frame on lubricant sensitivity during upscaling from a compaction simulator to a rotary tablet press Universiteit Gent
Formal upscaling and numerical validation of unsaturated flow models in fractured porous media Universiteit Hasselt
In this work, we consider a mathematical model for describing flow in an unsaturated porous medium containing a fracture. Both the flow in the fracture as well as in the matrix blocks are governed by Richards' equation coupled by natural transmission conditions. Using formal asymptotics, we derive upscaled models as the limit of vanishing ε, the ratio of the width and length of the fracture. Our results show that the ratio of porosities and ...
Rigorous Upscaling of Unsaturated Flow in Fractured Porous Media Universiteit Hasselt
In this work, we consider a mathematical model for flow in an unsaturated porous medium containing a fracture. In all subdomains (the fracture and the adjacent matrix blocks) the flow is governed by Richards' equation. The submodels are coupled by physical transmission conditions expressing the continuity of the normal fluxes and of the pressures. We start by analyzing the case of a fracture having a fixed width-length ratio, called ε > 0. ...
Analysis and upscaling of a reactive transport model in fractured porous media with nonlinear transmission condition Universiteit Hasselt
We consider a reactive transport model in a fractured porous medium. The particularity appears in the conditions imposed at the interface separating the block and the fracture, which involves a nonlinear transmission condition. Assuming that the fracture has thickness ε, we analyze the resulting problem and prove the convergence toward a reduced model in the limit ε↘0. The result is a model defined on an interface (the reduced fracture) and ...
