Fitting the topology of synthetic particle systems with a novel graph representation
Martin Alexander Memmesheimer, Claudia Redenbach
The shape and arrangement of particles in a material determine its macroscopic properties. The generation of synthetic data with varying particle structure, often represented as 3D…
Synthetic Defect Geometries of Cast Metal Objects Modeled via 2d Voronoi Tessellations
Natascha Jeziorski, Petra GospodnetiÄ, Claudia Redenbach
In industry, defect detection is crucial for quality control. Non-destructive testing (NDT) methods are preferred as they do not influence the functionality of the object while ins…
Increasing Inter-Fiber Contact in the Altendorf-Jeulin Model
Alex Keilmann, Claudia Redenbach, Francois Willot
In fields such as material design or biomedicine, fiber materials play an important role. Fiber simulations, also called digital twins, provide a basis for testing and optimizing t…
Fitting Generalized Power Diagrams to 3D Image Data: A Prerequisite for Virtual Materials Testing
Andreas Alpers, Orkun Furat, Christian Jung +4
This paper reviews algorithmic and modeling approaches for fitting generalized power diagrams to three-dimensional image data, a key step in virtual materials testing (VMT). Beyond…
Goodness-of-fit tests for spatial point processes: A power study
Chiara Fend, Claudia Redenbach
Spatial point processes are used as models in many different fields ranging from ecology and forestry to cosmology and materials science. In recent years, model validation, and in…
Bayesian inference for Neyman-Scott point processes with anisotropic clusters
JiÅà DvoÅák, Emily Ewers, Tomáš MrkviÄka +1
There are few inference methods available to accommodate covariate-dependent anisotropy in point process models. To address this, we propose an extended Bayesian MCMC approach for…
