Internet database of 3D Voronoi tessellations
Ponížil, P. ; Saxl, Ivan
A detailed description of the Internet database of the geometric properties ofVoronoi tessellations covering a wide range of situations starting with lattice tilings and ending with locally highly inhomogeneous case generated by Bernoulli cluster and mixed point fields.
3D stationary anisotropic fibre processes: Estimations of the rose of directions
Hlawiczková, M. ; Prokešová, M. ; Ponížil, P. ; Saxl, Ivan
Selected results of stereological analysis of the anisotropy of 3D fibre processes by means of the EM estimator and by the Bayesian approach are presented.
Stereology of stationary fibre processes in Rd
Saxl, Ivan ; Hlawiczková, M. ; Ponížil, P.
Stereological methods of the fibre process anisotropy based on the notion of the Steiner compact are reviewed and demonstrated for selected processes in 2D and 3D.
Geometrický výběr
Saxl, Ivan ; Beneš, V.
Objektem statistického hodnocení bývají stále častěji data popisující objekty nejrůznějšího druhu rozmístěné v prostoru. Předmětem zkoumání jsou jednak objekty samotné, resp. jejich prostorové rozmístění, jednak jejich vnitřní struktura, rozmístění jejích komponent příp. jejich interakce.
Spatial Voronoi tessellations: Report on extensive database
Saxl, Ivan ; Ponížil, P.
The Internet accessible database of spatial and sectional Voronoi tessellations is described in detail, possible applications are mentioned.
Classification of 3D tesellations
Saxl, Ivan ; Ponížil, P.
Classification of Voronoi tessellations generated by various point processes is proposed and discussed, the previously proposed models are reviewed and commented.
Simulated Intergranular Fracture Characteristics
Ponížil, P. ; Saxl, Ivan
Modeling of intergranular crack propagation in computer simulated tessellations; the effect of cell size distribution on fracture characteristic is examined and the recent theoretical asumptions and models are discussed.
Microstructural Characteristics of Dispersion Strengthned Cu-based System
Velgosová, O. ; Saxl, Ivan ; Besterci, M.
An example of application of the proposed improved procedure for grain size estimation to a real dispersion strengthned material.
Shapes of Random Closed Sets
Saxl, Ivan ; Ponížil, P.
An overview of the shape properties of Voronoi cells generated by point processes include a wide scale of situations ranging from isohedral tilings to tessellations with practically unlimited cell size dispersion. Cell shape characteristics are an important supplementary tool of the induced tessellation analysis.
Markov point process: 3D Voronoi tessellation generated by Strauss process
Bodlák, M. ; Ponížil, P. ; Saxl, Ivan
The analysis of tessellations generated by the Strauss point process at various values of its parameters is presented: the possibilities to construct processes with low cell size dispersion are discussed in detail.
