Applied Latin Hypercube stochastic method to quantify the uncertainty in groundwater equation model simulations [PDF]
E3S Web of Conferences, 2021 It is accepted that digital models simplify the physical reality that is the object of the modeling. Hydrodynamic modeling is an approach with high uncertainties in this context.

Groundwater flow equation, overview, derivation, and solution [PDF]
E3S Web of Conferences, 2021 Darcy’s law is the basic law of flow, and it produces a partial differential equation is similar to the heat transfer equation when coupled with an equation of continuity that explains the conservation of fluid mass during flow through a porous media ...

Noncommutative-Geometry Wormholes Based on the Casimir Effect [PDF]
Journal of High Energy Physics Gravitation and Cosmology, 2023 While wormholes are as good a prediction of Einstein's theory as black holes, they are subject to severe restrictions from quantum field theory. In particular, holding a wormhole open requires a violation of the null energy condition, calling for the ...

A study of water infiltration basin and clogging using column experiments [PDF]
E3S Web of Conferences, 2021 The clogging of infiltration basins is the main problem affecting the proper functioning of groundwater artificial recharge systems. In this study, several parameters have been varied to understand their impacts on water infiltration.

From noncommutative geometry to random matrix theory [PDF]
Journal of Physics A: Mathematical and Theoretical, 2022 We review recent progress in the analytic study of random matrix models suggested by noncommutative geometry. One considers fuzzy spectral triples where the space of possible Dirac operators is assigned a probability distribution.

Noncommutative geometry from perturbative quantum gravity [PDF]
Physical Review D, 2022 Trying to connect a fundamentally non-commutative spacetime with the conservative perturbative approach to quantum gravity, we are led to the natural question: are non-commutative geometrical effects already present in the regime where perturbative ...

Sobolev algebras on Lie groups and noncommutative geometry [PDF]
Journal of Noncommutative Geometry, 2022 We show that there exists a quantum compact metric space which underlies the setting of each Sobolev algebra associated to a subelliptic Laplacian $\Delta=-(X_1^2+\cdots+X_m^2)$ on a compact connected Lie group $G$ if $p$ is large enough, more precisely ...

Spectral Truncations in Noncommutative Geometry and Operator Systems [PDF]
Communications in Mathematical Physics, 2020 In this paper we extend the traditional framework of noncommutative geometry in order to deal with spectral truncations of geometric spaces (i.e. imposing an ultraviolet cutoff in momentum space) and with tolerance relations which provide a coarse grain ...

Wormhole Solutions in Symmetric Teleparallel Gravity with Noncommutative Geometry
Symmetry, 2021 This article describes the study of wormhole solutions in f(Q) gravity with noncommutative geometry. Here, we considered two different f(Q) models—a linear model f(Q)=αQ and an exponential model f(Q)=Q−α1−e−Q, where Q is the non-metricity and α is the ...

Quasifolds, diffeology and noncommutative geometry [PDF]
Journal of Noncommutative Geometry, 2020 After embedding the objects quasifolds into the category {Diffeology}, we associate a C*-agebra with every atlas of any quasifold, and show how different atlases give Morita equivalent algebras.
