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 ...
State-feedback Control Principles for Inverted Pendulum with Hysteresis in Suspension
In this paper we consider the mathematical model of the inverted pendulum with the hysteretic nonlinearity (in the form of a backlash) under state feedback control. The analytic results for the stability criteria as well ...
Correctness of the Two-dimensional Cauchy Problem for a Polynomial Difference Operator with Constant Coeffcients
The correctness of Cauchy problem for a polynomial difference operator is studied. An easily verifiable sufficient condition for correctness of a two-dimensional Cauchy problem for an operator with constant coefficients is proved.
Numerical Simulation of Magnetic Microstructure in Nanocrystalline Thin Films with the Random Anisotropy
The magnetic structure of thin nanocrystalline films with a random distribution of magnetization easy axes was studied by means of micromagnetic modeling. The dependences of the correlation function parameters of the ...
Micromagnetic Simulation of Magnetization Reversal Processes in Thin Obliquely Deposited Films
The magnetization reversal processes in thin obliquely deposited films were studied by means of micro- magnetic modeling. Thin film structures for micromagnetic study were generated by Monte Carlo film growth simulator. ...
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 ...
On an analogue of the Riemann-Hilbert problem for a non-linear perturbation of the Cauchy-Riemann operator
We consider a non-linear perturbation of a famous Riemann-Hilbert problem on the recovering of a holomorphic function in a domain via its real part on the boundary. We get an information on the local structure of the ...
