Flow Regime Analysis of the Pressure Build-Up during CO2 Injection in Saturated Porous Rock Formations

open access: yesEnergies, 2019
In this work, we are concerned with the theoretical and numerical analysis of the pressure build-up on the cap of an aquifer during CO2 injection in saturated porous rock formations in all flow regimes of the problem.

Optimized Self-Similar Borel Summation

open access: yesAxioms, 2023
The method of Fractional Borel Summation is suggested in conjunction with self-similar factor approximants. The method used for extrapolating asymptotic expansions at small variables to large variables, including the variables tending to infinity, is ...

Self-similar hyperbolicity [PDF]

open access: yesErgodic Theory and Dynamical Systems, 2017
In this paper we consider expansive homeomorphisms of compact spaces with a hyperbolic metric presenting a self-similar behavior on stable and unstable sets. Several applications are given related to Hausdorff dimension, entropy, intrinsically ergodic measures and the transitivity of expansive homeomorphisms with canonical coordinates.

The visible part of plane self-similar sets [PDF]

open access: yes, 2012
JMF was supported by an EPSRC grant whilst undertaking this work.Given a compact subset F of R2, the visible part VθF of F from direction θ is the set of x in F such that the half-line from x in direction θ intersects F only at x. It is suggested that if

Remaining Useful Life Prediction of Roller Bearings Based on Fractional Brownian Motion

open access: yesFractal and Fractional
Roller bearing degradation features fractal characteristics such as self-similarity and long-range dependence (LRD). However, the existing remaining useful life (RUL) prediction models are memoryless or short-range dependent.

Self similar collapse and the Raychaudhuri equation

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The role of the Raychaudhuri equation in studying gravitational collapse is discussed. A self-similar distribution of a scalar field along with an imperfect fluid in a conformally flat spacetime is considered for the purpose.

Asymptotic Formula for the Moments of Lebesgue’s Singular Function

open access: yesМоделирование и анализ информационных систем, 2015
Recall Lebesgue’s singular function. Imagine flipping a biased coin with probability p of heads and probability q = 1 − p of tails. Let the binary expansion of ξ ∈ [0, 1]: ξ = ∑∞ k=1 ck2−k be determined by flipping the coin infinitely many times, that is ...

Global Self‐Similar Scaling of Terrestrial Carbon With Aridity

open access: yesGeophysical Research Letters, 2023
While it is well known that water availability controls vegetation growth and soil microbial activity, how aridity affects ecosystem carbon patterns is not completely understood. Toward a more quantitative assessment of terrestrial carbon stocks, here we
