Semi-Grant-Free NOMA: A Stochastic Geometry Model [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2020
Grant-free (GF) transmission holds promise in terms of low latency communication by directly transmitting messages without waiting for any permissions. However, collision situations may frequently happen when limited spectrum is occupied by numerous GF ...

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.

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.

The stochastic geometry of invasion percolation [PDF]

open access: yesCommunications in Mathematical Physics, 1985
Invasion percolation, a recently introduced stochastic growth model, is analyzed and compared to the critical behavior of standardd-dimensional Bernoulli percolation. Various functions which measure the distribution of values accepted into the dynamically growing invaded region are studied.

A Stochastic Geometry Approach to Doppler Characterization in a LEO Satellite Network [PDF]

open access: yesICC 2020 - 2020 IEEE International Conference on Communications (ICC), 2020
A Non-terrestrial Network (NTN) comprising Low Earth Orbit (LEO) satellites can enable connectivity to underserved areas, thus complementing existing telecom networks. The high-speed satellite motion poses several challenges at the physical layer such as

Geometric thermodynamics for the Fokker–Planck equation: stochastic thermodynamic links between information geometry and optimal transport [PDF]

open access: yesInformation Geometry, 2022
We propose a geometric theory of non-equilibrium thermodynamics, namely geometric thermodynamics, using our recent developments of differential-geometric aspects of entropy production rate in non-equilibrium thermodynamics.

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.

Modeling, Analysis, and Optimization of Grant-Free NOMA in Massive MTC via Stochastic Geometry [PDF]

open access: yesIEEE Internet of Things Journal, 2020
In the massive machine-type communications (mMTCs) scenario for Internet-of-Things (IoTs) applications, though a large number of devices are registered to an access point (AP), very few of them are active with uplink short packet transmission ...

The stochastic dynamics of nanoscale mechanical oscillators immersed in a viscous fluid [PDF]

open access: yes, 2004
The stochastic response of nanoscale oscillators of arbitrary geometry immersed in a viscous fluid is studied. Using the fluctuation-dissipation theorem it is shown that deterministic calculations of the governing fluid and solid equations can be used in

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 ...
