Direct Solution of Modulus Constraints
"... The modulus constraint is a constraint on the position of the plane at infinity (1 ) which applies to the problem of selfcalibration in the case of constant internals. For any pair of cameras which are known to have the same internal parameters, the classical modulus constraint is the vanishing of ..."

STABILITY MODULUS SINGULAR SETS
"... Abstract. A new concept of stability, closely related to that of structural stability, is introduced and applied to the study of C r endomorphisms with singularities. A map that is stable in this sense will be conjugated to each perturbation that is equivalent to it in a geometric sense. It will be ..."

Geometric Realizations Of Substitutions
 BULL. SOC. MATH. FRANCE
, 1998
"... Substitution dynamical systems are abstract objects and it is therefore natural to look for ways of representing them geometrically. In this article we give geometric realizations for a large class of substitutions. We only require that the substitution be primitive and that the incidence matrix ..."

On the elastic modulus degradation in continuum damage mechanics
 Comput. Struct. 2000
"... Abstract To measure accurately the elastic modulus of a metal, E, can be a dicult task when a specimen undergoes plastic strains. Moreover, some failure criteria, such as those associated with Continuum Damage Mechanics, require the change of elastic modulus with strain to de®ne a measure of damage ..."

It is shown in this article, with the aid of a numerical simulation, that any plastic strains induce important
