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...

La présente recherche tend à montrer que la propension d’un acte de langage devenir fait institutionnel et ainsi « se faire politique » tient sa force illocutoire complexe construction implicite (Anquetil, paraître). En prenant appui sur l’exemple d’ALERTER, nous déterminerons comment le processus d’institutionnalisation en trois phases – 1. l’assignation d’une fonction agentive aux faits insti...

the increasing reliance on information gathered from the web and other internet technologies raise the issue of trust. through the development of semantic web, one major difficulty is that, by its very nature, the semantic web is a large, uncensored system to which anyone may contribute. this raises the question of how much credence to give each resource. each user knows the trustworthiness of ...

In this note we study the temporal convergence of a locally implicit discontinuous Galerkin (DG) method for Maxwell’s equations modeling electromagnetic wave propagation. Particularly, we wonder whether the method retains its second-order ordinary differential equation (ODE) convergence under stable simultaneous space-time grid refinement towards the true partial differential equation (PDE) sol...

This paper introduces a new model of deformable surfaces designed for animation, which we call active implicit surfaces. The underlying idea is to animate a potential field defined by discrete values stored in a grid, rather than directly animating a surface. This surface, defined as an iso-potential of the field, has the ability to follow a given object using a snake-like strategy. Surface ten...
