The meshless method plays an important role in solving problems in computational mechanics where conventional computational methods are not well suited. In this paper, we examine the property of the kernel matrix and investigate the convergence and timing performance of some well-known Krylov subspace methods on solving linear systems from meshless discretizations.

The increasing use of GPS and data integration technologies in agricultural operations has led to large gains in operational e‰ciencies. This paper presents a new method to bridge periods when the number of visible GPS satellites falls below the minimum required to provide a navigation solution by utilising an external positioning system. This can be an additional dead reckoning INS system or a...

Abstract. These notes give a state of the art of numerical homogenization methods for linear elliptic equations. The guideline of these notes is analysis. Most of the numerical homogenization methods can be seen as (more or less different) discretizations of the same family of continuous approximate problems, which H-converges to the homogenized problem. Likewise numerical correctors may also b...

The FN method is used to establish accurate numerical results for the albedo and the exit distribution of radiation relevant to an illuminated semi-infinite half space with an exponentially varying albedo for single scattering.

It is known that if x is a real residue character modulo k with x(p) = — 1 k n for the first five primes p, then the corresponding Fekete polynomial £„=j X(n)x changes sign on (0, 1). In this paper it is shown that the condition that x(p) be — 1 for the first four primes p is not sufficient to guarantee such a sign change. More specifically, if x ¡s the real nonprincipal character modulo either...

Mixed hidden Markov models represent an interesting tool for the analysis of longitudinal data. They allow to account for both time-constant and time-varying sources of unobserved heterogeneity,which are frequent in this kind of studies. Individual-specific latent features, which may be either constant or varying over time, are included in the linear predictor and lead to a general form of depe...

The geometric quantities of cross-sectional area, volume, and surface area have been calculated, to three-decimal-place accuracy, using the normal range of dimensional values for mammalian red blood cells. The calculations are based on the formulas for the geometric quantities originally derived by Funaki and rederived by the authors. The calculations for the surface area differ from those foun...

Some physical results in four dimensional large N gauge theories on a periodic torus are summarized.

Answer to cond-mat/0106005, cond-mat/0106006 and additional notes are given concerning my previous comment (cond-mat/0105325). Recently I have discussed the numerical results for the Anderson transition [1]. Objections [2] and [3] have appeared after that. We answer here to the arguments of [2, 3] and give the additional comments. 1. I did not state in [1] that ν = 1 (in fact, my most probable ...

After giving an introduction to spin glasses, I will discuss recent numerical results on two topics which have been of interest in the field for many years: (i) whether there is a finite temperature phase transition in isotropic vector (e.g. Heisenberg) spin glasses, and (ii) whether there is a phase transition (called the AT line) in a spin glass in a magnetic field.
