In this paper, we provide a convergence analysis of a projection semi-implicit scheme for the simulation of fluid-structure systems involving an incompressible viscous fluid. The error analysis is performed on a fully discretized linear coupled problem: a finite element approximation and a semiimplicit time-stepping strategy are respectively used for space and time discretization. The fluid is ...

We present in this paper a new curve and surface implicit model. This implicit model based on hyperquadrics allows a local and global control of the shape and a wide variety of allowable shapes. We deene a hybrid hyperquadric model by introducing implicitly some local properties on a global shape model. The advantage of our model is that it describes global and local properties through a unique...

We consider the elastic theory of single crystals at constant temperature where the free energy density depends on the local concentration of one or more species of particles in such a way that for a given local concentration vector certain lattice geometries (phases) are preferred. Furthermore we consider possible large deformations of the crystal lattice. After deriving the physical model, we...

We introduce a time-implicite Voronoi box based finite volume discretization for the initial-boundary value problem of a scalar nonlinear viscous conservation law in a one, twoor threedimensional domain. Using notations from the theory of explicit finite volume methods for hyperbolic problems and results from the Perron-Frobenius theory of nonnegative matrices, we establish various existence, s...

Artykuł prezentuje charakteryzację kobiet, które w Nowym Testamencie określone są explicite lub implicite jako głosicielki Ewangelii: (1) Maria Magdalena i inne kobiety przy grobie Jezusa; (2) kobieta samarytańska J 4, 4–42; (3) Pryska/Pryscylla; (4) Ewodia Syntyche z Flp 2–3. zwraca uwagę na historyczny teologiczny kontekst ich działalności oraz definiuje treść przedmiot głoszenia, czyli Ewang...

Au cours de la première moitié du XXe siècle, le patronat suisse l’industrie des machines et métaux renouvèle en profondeur les comptabilités ses entreprises. Si rapports publiés tendent désormais à invisibiliser données production, particulier travail salarié, interne, services comptables établissent progressivement statistiques d’une extrême précision sur temps rentabilité production. L’objec...

Different time-discretization methods for equivalent-control based sliding mode control (ECB-SMC) are presented. A new discrete-time sliding mode control scheme is proposed for linear time-invariant (LTI) systems. It is error-free in the discretization of the equivalent part of the control input. Results from simulations using the various discretized SMC schemes are shown, with and without pert...
