Filtration of the underground water to the workings of a large diameter
Известия высших учебных заведений: Геология и разведка, 2019 An approximate solution obtained by the author for the problem of the flow of pressure groundwater to a large-diameter water receiving system with a disturbed aquifer with a constant flow rate has been given. The solution has been obtained using the most

The Approximate Solution of Some Plane Boundary Value Problems of the Moment Theory of Elasticity
Advances in Mathematical Physics, 2016 We consider a two-dimensional system of differential equations of the moment theory of elasticity. The general solution of this system is represented by two arbitrary harmonic functions and solution of the Helmholtz equation.

The Wiener-Hopf solution of the isotropic penetrable wedge problem: diffraction and total field [PDF]
, 2011 The diffraction of an incident plane wave by an isotropic penetrable wedge is studied using generalized Wiener-Hopf equations, and the solution is obtained using analytical and numerical-analytical approaches that reduce the Wiener-Hopf factorization to ...

Approximate Coalgebra Homomorphisms and Approximate Solutions
, 2020 Terminal coalgebras $$\nu F$$ of finitary endofunctors F on categories called strongly lfp are proved to carry a canonical ultrametric on their underlying sets. The subspace formed by the initial algebra $$\mu F$$ has the property that for every coalgebra A we obtain its unique homomorphism into $$\nu F$$ as a limit of a Cauchy sequence of morphisms ...

DBD Plasma: Explicit Model with Integral Approximate Solution to Wall Jet
, 2018 : This study aims to first introduce a formulation which is quite simple for obtaining dielectric-barrier discharge plasma spatial body force. This new model comprises a combination of an empirical model and a numerical one. Although there are still some

An Approximate Solution of Blasius Equation by using HPM Method [PDF]
, 2012 In this study, Homotopy Perturbation Method (HPM) is used to provide an approximate solution to the Blasius nonlinear differential equation that describes the behaviour of a two-dimensional viscous laminar flow over a flat plate.

An approximate method for the solution of an influence function foil rolling model
, 2004 Fleck and Johnson (Int. J. Mech. Sci. 29 (1987) 507) and Fleck et al. (Proc. Inst. Mech. Eng. 206 (1992) 119) have developed foil rolling models which allow for large deformations in the roll profile, including the possibility that the rolls flatten ...
