Smoothing by cubic spline modified applied to solve inverse thermal problem
(2018-05-01)
This paper presents an alternative to cubic spline regularization and its weighted form applied in solving inverse thermal problems. The inverse heat transfer problems are classified as ill-posed, that is, the solution may ...

LOCAL WELL POSEDNESS, ASYMPTOTIC BEHAVIOR AND ASYMPTOTIC BOOTSTRAPPING FOR A CLASS OF SEMILINEAR EVOLUTION EQUATIONS OF THE SECOND ORDER IN TIME
(AMER MATHEMATICAL SOC, 2009)
A class of semilinear evolution equations of the second order in time of the form u(tt)+Au+mu Au(t)+Au(tt) = f(u) is considered, where -A is the Dirichlet Laplacian, 92 is a smooth bounded domain in R(N) and f is an element ...
Euler scheme for solutions of a countable system of stochastic differential equations
(Elsevier, 2001-10-01)
We consider a countable system of stochastic differential equation. Euler scheme for approximating these solutions is used, and the global error is estimated. Solutions are approximated by means of a process which takes ...

GLOBAL WELL-POSEDNESS AND NON-LINEAR STABILITY OF PERIODIC TRAVELING WAVES FOR A SCHRODINGER-BENJAMIN-ONO SYSTEM
(AMER INST MATHEMATICAL SCIENCES, 2009)
The objective of this paper is two-fold: firstly, we develop a local and global (in time) well-posedness theory for a system describing the motion of two fluids with different densities under capillary-gravity waves in a ...
Global solutions of approximation problems in Hilbert spaces
(Taylor & Francis, 2019-10)
We study three well-known minimization problems in Hilbert spaces: the weighted least squares problem and the related problems of abstract splines and smoothing. In each case we analyze the solvability of the problem for ...
Existência global de soluções para certos sistemas parabólicos não lineares
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Matemática - PPGM, 2005-03-02)
In this work, we study the global existence of smooth solutions for certain
systems of the form ut + f(u)x = Duxx, where u and f are vectors and D
is a positive, constant and diagonalizable matrix. We assume that the ...
