A set of algorithms to correct a geometry in order to be meshed
(2000)
Text en actes de congrés
Accés obertOne of the major difficulties in meshing 3D complex geometries is to deal with non proper geometrical definitions coming from CAD systems. Typically, CAD systems don’t take care of the proper definition of the geometries ... -
A Set of rules for a constructive geometric constraint solver
(1995-04)
Report de recerca
Accés obertThis work presents the set of constructive rules used by a two-dimensional, variational geometric constraint solver based on a constructive approach. The main goal in defining the rules has been to keep the set of rules ... -
A set simulation approach to the computation of invariant sets for nonlinear systems
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Comunicació de congrés
Accés restringit per política de l'editorialGiven a nonlinear discrete-time system, previous works exist that compute invariant sets as finite unions of boxes. Set inversion algorithms based on interval arithmetic are used to obtain inner approximations of the one ... -
