Optimization and pre-clinical perception of an artificial simulator for endodontic training : a preliminary study

Lieven Robberecht, Jean-Christophe Hornez, Marion Dehurtevent, Thomas Dufour, Julien Labreuche, Etienne Deveaux, Feng Chai

The aim of this study was to evaluate the performance of ceramic, hybrid ceramic, and commercial plastic bloc root canal simulator (RCS) as preclinical training aids in the learning phase of endodontic treatments. A previously developed hydroxyapatite ceramic RCS was improved by adding epoxy resin…

δ ] (2, 2)-ideal centroaffine hypersurfaces of dimension 5

Handan Yildirim, Luc Vrancken

The notion of an ideal submanifold was introduced by Chen at the end of the last century. A survey of recent results in this area can be found in his book [9]. Recently, in [10], an optimal collection of Chen's inequalities was obtained for Lagrangian submanifolds in complex space forms. As…

On four-dimensional Einstein affine hyperspheres

Zejun Hu, Haizhong Li, Luc Vrancken

It is well-known that Vrancken–Li–Simon classified locally strongly convex affine hyperspheres in Rn+1 whose affine metric are of constant sectional curvatures, but on the other side it is still a difficult problem to classify n-dimensional locally strongly convex affine hyperspheres whose affine…

Nouveaux modèles géométriques pour la C.A.O. et la synthèse d’images

Jean-Paul Becar, Lionel Garnier

La géométrie du 21ème siècle est indissociable de l'ordinateur. La performance des logiciels de géométrie qu'ils soient gratuits ou sous licence d'exploitation s'accroit de jour en jour. La plupart repose sur la représentation de courbes à l'aide de points de contrôle…

Sintering of Ceramics

Anne Leriche, Stuart Hampshire, Francis Cambier

This chapter gives an overview of surface and bulk matter transport processes occurring during the densification of ceramic powder compacts. Starting from purified or chemically synthesized raw materials, sintering takes place by either solid state or liquid phase mechanisms during heat treatment…

Spectral analysis of a generalized buckling problem on a ball

Colette De Coster, Serge Nicaise, Christophe Troestler

In this paper, the spectrum of the following fourth order problem (Formula Presented.)where D1 is the unit ball in RN, is determined for ν< 0 as well as the nodal properties of the corresponding eigenfunctions. In particular, we show that the first eigenvalue is simple and that the corresponding…

Adapted Numerical Methods for the Poisson Equation with $L^2$ Boundary Data in NonConvex Domains

Thomas Apel, Serge Nicaise, Johannes Pfefferer

The very weak solution of the Poisson equation with L 2 boundary data is defined by the method of transposition. The finite element solution with regularized boundary data converges in the L 2 (Ω)-norm with order 1/2 in convex domains but has a reduced convergence order in nonconvex domains…

Generalized Yangians and their Poisson counterparts

Dimitri Gurevich, Pavel Saponov

By generalized Yangians, we mean Yangian-like algebras of two different classes. One class comprises the previously introduced so-called braided Yangians. Braided Yangians have properties similar to those of the reflection equation algebra. Generalized Yangians of the second class, RTT-type…
