An introduction to incidence geometry Universiteit Gent
Some contributions to incidence geometry and the polynomial method Universiteit Gent
Quotients of incidence geometries Vrije Universiteit Brussel
We develop a theory for quotients of geometries and obtain sufficient
conditions for the quotient of a geometry to be a geometry. These
conditions are compared with earlier work on quotients, in particular
by Pasini and Tits. We also explore geometric properties such as connectivity,
firmness and transitivity conditions to determine when they are preserved under
the quotienting operation. We show that the class of ...

Wear patterns in knee OA correlate with native limb geometry KU Leuven Universiteit Antwerpen
Background: To date, the amount of cartilage loss is graded by means of discrete scoring systems on artificially divided regions of interest (ROI). However, optimal statistical comparison between and within populations requires anatomically standardized cartilage thickness assessment. Providing anatomical standardization relying on non-rigid registration, we aim to compare morphotypes of a healthy control cohort and virtual reconstructed twins ...
Impact of roof geometry of an isolated leeward sawtooth roof building on cross-ventilation: Straight, concave, hybrid or convex? KU Leuven
© 2015 Elsevier Ltd. The roof geometry of a leeward sawtooth roof building can have a large influence on the cross-ventilation flow. In this paper, five different leeward sawtooth roof geometries are evaluated using Computational Fluid Dynamics (CFD). The 3D CFD simulations are performed using the steady Reynolds-Averaged Navier-Stokes approach with the SST k- ω turbulence model to provide closure to the governing equations. The computational ...

Geometry of the inversion in a finite field and partitions of PG(2k−1,q)in normal rational curves. Vrije Universiteit Brussel
Let L=Fqn be a finite field and let F=Fq be a subfield of L. Consider L as a vector space over F and the associated projective space that is isomorphic to PG(n − 1, q). The properties of the projective mapping induced by x↦x−1 have been studied in Csajbók (Finite Fields Appl. 19:55–66, 2013), Faina et al. (Eur. J. Comb. 23:31–35, 2002), Havlicek (Abh. Math. Sem. Univ. Hamburg 53:266–275, 1983), Herzer (Abh. Math. Sem. Univ. Hamburg 55:211–228 ...
Comparative incidence rates of mild adverse effects to transcranial magnetic stimulation Universiteit Gent
Objectives: Past research has largely neglected to investigate mild adverse effects (MAEs) to transcranial magnetic stimulation (TMS), including headache and nausea. Here we explored the relationship between MAEs, participant characteristics (age and gender) and protocol parameters, including mode of application, coil geometry, stimulated brain region, TMS frequency, TMS intensity, and active vs. sham stimulation. Methods: Data from 1270 ...
