HOW MANY LOBSTERS ARE IN THE SEA?

open access: yesImage Analysis and Stereology, 2011
A lobster fishery must have a reasonable estimate of the number of lobsters within the fishery in order to regulate the annual harvest. Stereological sampling procedures are used to estimate the number of lobsters in a defined region of the sea.

The eternal fractal in the universe [PDF]

open access: yes, 2001
Models of eternal inflation predict a stochastic self-similar geometry of the universe at very large scales and allow existence of points that never thermalize.

Information Geometry on Complexity and Stochastic Interaction

open access: yesEntropy, 2015
Interdependencies of stochastically interacting units are usually quantified by the Kullback-Leibler divergence of a stationary joint probability distribution on the set of all configurations from the corresponding factorized distribution.

Information Geometry of Spatially Periodic Stochastic Systems

open access: yesEntropy, 2019
We explore the effect of different spatially periodic, deterministic forces on the information geometry of stochastic processes. The three forces considered are f 0 = sin ( π x ) / π and f ± = sin ( π x ) / π

Discrete stochastic approximations of the Mumford-Shah functional [PDF]

open access: yes, 2019
We propose a $\Gamma$-convergent discrete approximation of the Mumford-Shah functional. The discrete functionals act on functions defined on stationary stochastic lattices and take into account general finite differences through a non-convex potential ...

Dimensioning of 5G Networks by Using Stochastic Geometry

open access: yesInternational Journal of Information and Communication Technology Research, 2021
In this paper, we propose an analytical model for dimensioning of Orthogonal Frequency Division Multiple Access (OFDMA) systems in 5G networks by considering Internet of Thing (IoT) application using stochastic geometry.

Stochastic quantization on Lorentzian manifolds

open access: yesJournal of High Energy Physics, 2021
We embed Nelson’s theory of stochastic quantization in the Schwartz-Meyer second order geometry framework. The result is a non-perturbative theory of quantum mechanics on (pseudo-)Riemannian manifolds.

KV. Cohomology and some applications [PDF]

open access: yes, 2020
Two versions of the KV-cohomology are presented and some algebraic and geometrical applications are given. We will see some applications to stochastic manifold. As a consequence, we can apply these ideas in Lorentzian geometry, in particular in

GRAPE: A Stochastic Geometrical 3D Model for Aggregates of Particles With Tunable 2D Morphological Projected Properties

open access: yesImage Analysis and Stereology, 2023
The main goal of this paper is to propose a method for the 3D morphological characterization of compact aggregates using 2D image analysis. The problem at hand is the 3D morphometric characterization of latex nanoparticle aggregates.

Ethnomathematics: Exploration of Fractal Geometry in Gate Ornaments of the Sumenep Jamik Mosque Using the Lindenmayer System

open access: yesIndonesian Journal of Science and Mathematics Education, 2023
Jamik Sumenep Mosque, a heritage site of the Sumenep Kingdom, was built to emphasize the acculturation of Chinese, Islamic, and Madurese cultures. This ethnomathematics research aims to reveal and explore the fractal geometry forms in the gateway of ...
