Micromagnetics and Numerical Analysis
Mathematical Models and Methods in Applied Sciences, 1997The 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.

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
2009The 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.

A numerical analysis of calendering
Journal of Non-Newtonian Fluid Mechanics, 1988An analysis of calendering of inelastic (power-law) and viscoelastic sheets of finite initial thickness has been carried out using (i) a perturbation method based on lubrication theory; (ii) an approximate treatment including normal stress effects; (iii) a full numerical analysis using the boundary element method.

Numerical Analysis of Bifurcations [PDF]
, 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, 1985In 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 analysis of sandwich beams
Computers & Structures, 1991This paper describes the development of a numerical model for the physical nonlinear analysis of simply supported sandwich beams, specifically with foamed-concrete cores and concrete faces. The long-term behaviour is included in view of creep and shrinkage of both faces and core. The structural behaviour of sandwich beams is described by a fourth-order

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.

Microprogramming and Numerical Analysis
IEEE Transactions on Computers, 1971This short note presents the view that microprogramming affords a technology that can provide a powerful, efficient, and versatile computer facility for numerical analysts. Particular areas of application are discussed. Fundamental questions are raised relevant to the exploitation of this technology by numerical analysts.
