METHODOLOGICAL FOUNDATIONS OF THE IMITATIONAL MODELLING OF THE GEOLOGICAL ENVIRONMENT OF THE MILITARY ACTIVITY TERRITORIES (AT THE DIVYCHKY POLYGON AS AN EXAMPLE)

open access: yesГеохімія техногенезу, 2021
The methodological basis of a theory for information support of research and work on management of the geological component of military activity territories is founded on the development of a typification of geological environment violations resulted ...

Gelfand―Tsetlin Polytopes and Feigin―Fourier―Littelmann―Vinberg Polytopes as Marked Poset Polytopes [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2011
Stanley (1986) showed how a finite partially ordered set gives rise to two polytopes, called the order polytope and chain polytope, which have the same Ehrhart polynomial despite being quite different combinatorially.

Physico-mathematical modeling of crossflow filtration [PDF]

open access: yesChemical Engineering Journal, 2005
Abstract A phenomenological model that allows the correlation of pressure fields, filtration rate and cake thickness in the process that results from the axial flow of a suspension in a duct that is provided with a porous wall is presented. The model is based in the motion and the continuity equations for the phases and incorporates the following ...

Separating Topological Noise from Features Using Persistent Entropy [PDF]

open access: yes, 2016
Topology is the branch of mathematics that studies shapes and maps among them. From the algebraic definition of topology a new set of algorithms have been derived.

Computer modeling and hydrogeological drafting of ground water level returns [PDF]

open access: yesE3S Web of Conferences
This paper develops a mathematical model and methods of hydrogeological calculations of the effect of water inflow on the rise of the water table. At present, a variety of mathematical methods are increasing used to analyze groundwater movement.

An essay on the general theory of stochastic processes [PDF]

open access: yes, 2006
This text is a survey of the general theory of stochastic processes, with a view towards random times and enlargements of filtrations. The first five chapters present standard materials, which were developed by the French probability school and which are

Gauss-Manin connections for p-adic families of nearly overconvergent modular forms [PDF]

open access: yes, 2014
We interpolate the Gauss-Manin connection in p-adic families of nearly overconvergent modular forms. This gives a family of Maass-Shimura type differential operators from the space of nearly overconvergent modular forms of type r to the space of nearly ...

On Some Mathematical Models of Filtration Theory

open access: yesBulletin of the South Ural State University. Series "Mathematical Modelling, Programming and Computer Software", 2015
The article is devoted to the study of some mathematical models arising in filtration theory. We examine an inverse problem of determining an unknown right-hand side and coefficients in a pseudoparabolic equation of the third order. Equations of this type and more general Sobolev-type equations arise in filtration theory, heat and mass transfer, plasma
