چکیده

This paper deals with convolution-type Urysohn equations of the first kind. Finding a solution for such is an ill-posed problem. For it to be solved, regularization algorithms and continuous wavelet transform are used. Similar Fourier transform, applied (based on transforms) unknown shift. The preferable cases approximated right-hand sides type 1 equations. We demonstrated that application Urysohn-type shift translates into nonlinear equation oscillating kernel. Depending availability priori information, combination iterative use close effective solving based equation.

APPLICATION OF DIFFERENTIAL TRANSFORM METHOD TO SOLVE HYBRID FUZZY DIFFERENTIAL EQUATIONS

In this paper, we study the numerical solution of hybrid fuzzy differential equations by using differential transformation method (DTM). This is powerful method which consider the approximate solution of a nonlinear equation as an infinite series usually converging to the accurate solution. Several numerical examples are given and by comparing the numerical results obtained from DTM  and  predi...

On Quadratic Integral Equations of Urysohn Type in Fréchet Spaces

0 u(t, s, x(s)) ds, t ∈ J := [0,+∞), where f : J → R, u : J × [0, T ] × R → R are given functions and A : C(J,R) → C(J,R) is an appropriate operator. Here C(J,R) denotes the space of continuous functions x : J → R. Integral equations arise naturally from many applications in describing numerous real world problems, see, for instance, books by Agarwal et al. [1], Agarwal and O’Regan [2], Cordune...

Numerical inversion of Laplace transform via wavelet in ordinary differential equations

This paper presents a rational Haar wavelet operational method for solving the inverse Laplace transform problem and improves inherent errors from irrational Haar wavelet. The approach is thus straightforward, rather simple and suitable for computer programming. We define that $P$ is the operational matrix for integration of the orthogonal Haar wavelet. Simultaneously, simplify the formulaes of...

Application of the wavelet transform to nanoscale thermal transport

The continuous wavelet transform is employed to analyze the dynamics and time-dependent energy distribution of phonon wave-packet propagation and scattering in molecular dynamics simulations. The equations of the one-dimensional continuous wavelet transform are presented and then discretized for implementation. Practical aspects and limitations of the transform are discussed, with attention to ...
