A cohomology-based Gromov–Hausdorff metric approach for quantifying molecular similarity [PDF]

open access: yesScientific Reports
We introduce a cohomology-based Gromov–Hausdorff ultrametric method to analyze 1-dimensional and higher-dimensional (co)homology groups, focusing on loops, voids, and higher-dimensional cavity structures in simplicial complexes, to address typical ...

Hausdorff Measures on Generalized Set Valued Neutrosophic Quadruple Numbers and Decision Making Applications for Adequacy of Online Education [PDF]

open access: yesNeutrosophic Sets and Systems, 2021
In this paper, we develop a new method of decision-making algorithm with Hausdorff distance and Hausdorff similarity measures based on generalized set-valued neutrosophic quadruple numbers.

On intersections of Cantor sets: Hausdorff measure [PDF]

open access: yesOpuscula Mathematica, 2013
We establish formulas for bounds on the Haudorff measure of the intersection of certain Cantor sets with their translates. As a consequence we obtain a formula for the Hausdorff dimensions of these intersections.

Determining the Hausdorff Distance Between Trees in Polynomial Time [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2021
The Hausdorff distance is a relatively new measure of similarity of graphs. The notion of the Hausdorff distance considers a special kind of a common subgraph of the compared graphs and depends on the structural properties outside of the common subgraph.

The Second Generalization of the Hausdorff Dimension Theorem for Random Fractals

open access: yesMathematics, 2022
In this paper, we present a second partial solution for the problem of cardinality calculation of the set of fractals for its subcategory of the random virtual ones.

On the usage of average Hausdorff distance for segmentation performance assessment: hidden error when used for ranking

open access: yesEuropean Radiology Experimental, 2021
Average Hausdorff distance is a widely used performance measure to calculate the distance between two point sets. In medical image segmentation, it is used to compare ground truth images with segmentations allowing their ranking.

A Generalization of the Hausdorff Dimension Theorem for Deterministic Fractals

open access: yesMathematics, 2021
How many fractals exist in nature or the virtual world? In this paper, we partially answer the second question using Mandelbrot’s fundamental definition of fractals and their quantities of the Hausdorff dimension and Lebesgue measure.

On the Fractal Measures and Dimensions of Image Measures on a Class of Moran Sets

open access: yesMathematics, 2023
In this work, we focus on the centered Hausdorff measure, the packing measure, and the Hewitt–Stromberg measure that determines the modified lower box dimension Moran fractal sets. The equivalence of these measures for a class of Moran is shown by having
