Modelling in Science Education and Learning, 2009 Els elements finits actualment constitueixen una eina fonamental per a resolució d’equacions diferencials en contextos reals. En aquest article presentem un bon exemple per al mètode: l’obtenció dels modes de ressonància sobre la tapa harmònica d’una ...

On the Equivalence of Finite Element and Finite Integration Formulations [PDF]
IEEE Transactions on Magnetics, 2010 The paper offers a comparative study of numerical methods of analysis of electromagnetic fields. The focus is on the finite element method (FEM) and finite integration technique (FIT), but with the cell and equivalent network approaches also considered.

The Serendipity Family of Finite Elements [PDF]
Foundations of Computational Mathematics, 2011 We give a new, simple, dimension-independent definition of the serendipity finite element family. The shape functions are the span of all monomials which are linear in at least s-r of the variables where s is the degree of the monomial or, equivalently, whose superlinear degree (total degree with respect to variables entering at least quadratically) is

Desenvolupament virtual de producte
Temes de Disseny, 2002 Avaluar la funcionalitat, la seguretat, la qualitat, etc. d'un producte, pot ser llarg i costós. Els prototipus i els assaigs reals són eines determinants, però el seu ús exhaustiu en la fase de creació del producte pot encarir aquest procés i retardar ...

Programari i escenaris de disseny
Temes de Disseny, 2002 En aquest article l'autor intenta centrar l'interès en els diferents aspectes que actualment estan involucrats en el procés de disseny, per acabar remarcant la creixen importància del factor humà, el treball en equip i els recursos de programari. Aquests

Modelling in Science Education and Learning, 2013 The mathematical model's validity used in computer programs are based on a specific formula implemented leading commercial software. Since these programs use their own databases of materials sometimes the question arises of what the miscalculation in ...

Early Medieval Europe, EarlyView.This article presents a newly discovered Latin text: a theological treatise titled Liber testimoniorum veteris testamenti that was written by Alcuin’s friend Candidus (Wizo) at the request of Charlemagne. By discussing selected passages from the Heptateuch, Candidus seeks to demonstrate that Jesus Christ and the Holy Spirit, thus the whole Christian ...

On the p-Elements of a Finite Group [PDF]
Proceedings of the American Mathematical Society, 1975 Let G be a finite group, p a prime, and x a p-element in G. An element g in G is called a witness of G if the subgroup generated by x and g is a p-group. The set of all witnesses of x in G is denoted by W(x). This paper shows that x belongs to a given Sylow p-subgroup P of G if one of the following holds: (1) G is p-solvable and W(x) Pfl n Ixgg E GI ...
