Mathematical Modeling of H-processes
The problem of the discrete continuous processes having "tubular" structure in space "input-output" variables’s modeling is investigated. The fact that when the trained parametrical models of "tubular" processes’s creating, ...
The inverse problem for the nonlinear pseudoparabolic equation of filtration type
The paper discusses the correctness of the inverse problem on finding an unknown coefficient dependent on t in the nonlinear pseudoparabolic equation of the third order with an additional information on the boundary. The ...
Finite Ion Size Effects on Electrolyte Transport in Nanofiltration Membranes
The pressure–driven electrolyte transport through nanofiltration membrane pores with specified wall po- tential is investigated theoretically. The finite ion size effect is taken into account by introducing an additional ...
Theoretical Study of Electrolyte Diffusion through Polarizable Nanopores
The diffusion of binary aqueous electrolytes through nanopores with dielectric as well as conductive surface is investigated theoretically on the basis of Space–Charge model. The latter is extended to the case of polarizable ...
An Elementary Algorithm for Solving a Diophantine Equation of Degree Four with Runge's Condition
We propose an elementary algorithm for solving a diophantine equation (p(x, y) + a1x + b1y)(p(x, y) + a2x + b2y)-dp(x, y)-a3x-b3y-c = 0 (*) of degree four, where p(x, y) denotes an irreducible quadratic form of positive ...
Modelling of Electrochemically Switchable Ion Transport in Nanoporous Membranes with Conductive Surface
The impact of potential applied to the conductive surface of nanoporous membrane on the membrane potential at zero current is investigated theoretically on the basis of two–dimensional Space–charge model. The membrane ...
