A finite element method with numerical quadrature is considered for the solution of a class of second-order quasilinear elliptic problems of nonmonotone type. Optimal a-priori error estimates for the H and the L norms are derived. The uniqueness of the finite element solution is established for a sufficiently fine mesh. Our results permit the analysis of numerical homogenization methods. To cit...

This paper presents a growth model for dominant-height and site-quality estimations for Pyrenean oak (Quercus pyrenaica Willd.) stands. The Bertalanffy–Richards function is used with the generalized algebraic difference approach to derive a dynamic site equation. This allows dominant-height and site-index estimations in a compatible way, using any desirable base age and allowing estimations to ...

In honor of the 100th birthday of the article, " Sur les groupes continus " Abstract: A methodical analysis of the research related to the article , " Sur les groupes continus " , of Henri Poincaré reveals many historical misconceptions and inaccuracies regarding his contribution to Lie theory. A thorough reading of this article confirms the precedence of his discovery of many important concept...

— We construct and analyze efficient fully discrete Galerkin type methods, that are of high order of accuracy and conservative in the L sense,for approximating the solution ofaform of the linear Schrödinger équation with a time-dependent coefficient, found e.g. in underwater acoustics. The time stepping procedures are based on the class of implicit Runge-Kutta methods known as the q-stage Gauss...

Mobile ad hoc networks as well as grid platforms are distributed, changing, and error prone environments. Communication costs within such infrastructure can be improved, or at least bounded, by using k-clustering. A k-clustering of a graph, is a partition of the nodes into disjoint sets, called clusters, in which every node is distance at most k from a designated node in its cluster, called the...

l'importance de la traduction dans le monde moderne éclate de façon flagrante. la traduction est présente dans mille aspects de la vie quotidienne. cette omniprésence est le témoignage d'une société où se multiplient les échanges internationaux dans tous les domaines. etant donné le nombre considérable de texte à traduire dans un temps limité, on voit des traductions de mauvaise qualité avec be...

The existing macroeconometric evidence lends support to the wage Phillips curve by showing a negative relation between the rate of change in wages and the unemployment rate, conditional on lagged price inflation. Most theoretical models of wage setting, however, generate a “wage curve,” described by a negative relation between the level of the real wage and unemployment. Real wage dynamics have...
