Improved stochastic rounding
Lu Xia, Martijn Anthonissen, Michiel Hochstenbach +1
Due to the limited number of bits in floating-point or fixed-point arithmetic, rounding is a necessary step in many computations. Although rounding methods can be tailored for diff…
Homogenization of a pseudo-parabolic system via a spatial-temporal decoupling: upscaling and corrector estimates for perforated domains
Arthur Johannes Vromans, Fons van de Ven, Adrian Muntean
In this paper, we determine the convergence speed of an upscaling of a pseudo-parabolic system containing drift terms with scale separation of size . Both the upscaling and…
Refined a posteriori error estimation for classical and pressure-robust Stokes finite element methods
P. L. Lederer, C. Merdon, J. Schöberl
Recent works showed that pressure-robust modifications of mixed finite element methods for the Stokes equations outperform their standard versions in many cases. This is achieved b…
Design and Processing of Invertible Orientation Scores of 3D Images for Enhancement of Complex Vasculature
M. H. J. Janssen, A. J. E. M. Janssen, E. J. Bekkers +2
The enhancement and detection of elongated structures in noisy image data is relevant for many biomedical imaging applications. To handle complex crossing structures in 2D images,…
Anisotropic interactions in a first-order aggregation model: a proof of concept
Joep H. M. Evers, Razvan C. Fetecau, Lenya Ryzhik
We extend a well-studied ODE model for collective behaviour by considering anisotropic interactions among individuals. Anisotropy is modelled by limited sensorial perception of ind…
Weakly Non-Equilibrium Properties of Symmetric Inclusion Process with Open Boundaries
Kiamars Vafayi, Manh Hong Duong
We study close to equilibrium properties of the one-dimensional Symmetric Inclusion Process (SIP) by coupling it to two particle-reservoirs at the two boundaries with slightly diff…
