Micromagnetics and Numerical Analysis

Mathematical Models and Methods in Applied Sciences, 1997
The structure of domain walls in ferromagnetic crystals is investigated by means of micromagnetics. Moreover, the numerical integration of one-dimensional micromagnetic equations in domain walls is carried out in order to obtain approximate expressions of the energy associated to these regions.

Numerical analysis

WIREs Computational Statistics, 2011
AbstractIn this article, we touch on a few selected topics illustrating the interplay between computational statistics and numerical analysis. Rather than briefly reviewing a long array of methods, on one hand we place emphasis on problems, such as stochastic optimization, which require the joint application of several techniques; on the other hand, we

Numerical Bifurcation Analysis

2009
The theory of dynamical systems studies the behavior of solutions of systems, like nonlinear ordinary differential equations (ODEs), depending upon parameters. Using qualitative methods of bifurcation theory, the behavior of the system is characterized for various parameter combinations.

Numerical Analysis of Bifurcations [PDF]

open access: possible, 1995
In this chapter we shall describe some of the basic techniques used in the numerical analysis of dynamical systems. We assume that low-level numerical routines like those for solving linear systems, finding eigenvectors and eigenvalues, and performing numerical integration of ODEs are known to the reader.

Numerical analysis of inflation

Physical Review D, 1985
In this paper the mechanism of a cosmological phase transition is addressed in a new way which avoids weaknesses of previous approaches. The effects of inhomogeneities are included explicitly. A numerical analysis is presented in which for a wide class of models the Universe enters a period of new inflation.

Numerical Welltest Analysis

Nigeria Annual International Conference and Exhibition, 2004
Abstract The importance of reservoir and well parameters estimated from BHP analysis, has made it necessary to analyze field pressure data as practically as possible. This has lead to the application of numerical solutions to BHP analysis.

Numerical Harmonic Analysis

1986
As we have seen in the previous programme, the determination of the coefficients in the Fourier series representation of a periodic function entails the evaluation of various integrals involving the function of the waveform.
