Grouting Treatment of Water and Mud Inrush in Fully Weathered Granite Tunnel: A Case Study

open access: yesGeofluids, Volume 2020, Issue 1, 2020., 2020
When mountain tunnel passes through completely weathered granite strata, water and mud inrush is easy to occur, causing casualties and economic losses. Grouting is a common and effective treatment method for water and mud inrush disaster. The current existing researches focus on theoretical analysis, numerical simulation, and laboratory test, and the ...

Mathematical modelling for malaria under resistance and population movement

open access: yesRevista Integración, 2020
In this work, two mathematical models for malaria under resistance are presented. More precisely, the first model shows the interaction between humans and mosquitoes inside a patch under infection of malaria when the human population is resistant to ...

Deligne-Beilinson Cohomology and Abelian Link Invariants

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
For the Abelian Chern-Simons field theory, we consider the quantum functional integration over the Deligne-Beilinson cohomology classes and we derive the main properties of the observables in a generic closed orientable 3-manifold. We present an explicit

A topology on inequalities

open access: yesElectronic Journal of Differential Equations, 2006
We consider sets of inequalities in Real Analysis and construct a topology such that inequalities usually called "limit cases" of certain sequences of inequalities are in fact limits - in the precise topological sense - of such sequences.

Approximations for uniformly continuous functions on groupoids [PDF]

open access: yesSurveys in Mathematics and its Applications, 2017
The purpose of this paper is to prove an approximation/extension theorem for a family of partial functions on a groupoid satisfying a uniform compatibility condition.

Existence and uniqueness of solutions of nonlinear mixed integrodifferential equations with nonlocal condition in Banach Spaces

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we study the existence and uniqueness of mild and strong solutions of a nonlinear mixed Volterra-Fredholm integrodifferential equation with nonlocal condition in Banach spaces.

Wavelet-Based Quantum Field Theory

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The Euclidean quantum field theory for the fields $phi_{Delta x}(x)$, which depend on both the position $x$ and the resolution $Delta x$, constructed in SIGMA 2 (2006), 046, on the base of the continuous wavelet transform, is considered.

Factor-Group-Generated Polar Spaces and (Multi-)Qudits

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Recently, a number of interesting relations have been discovered between generalised Pauli/Dirac groups and certain finite geometries. Here, we succeeded in finding a general unifying framework for all these relations.

Tribes of cubic partial cubes

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2007
Partial cubes are graphs isometrically embeddable into hypercubes. Three infinite families and a few sporadic examples of cubic partial cubes are known.
