Coupled Electro-Thermo-Mechanical Finite Element Modeling of the Spark Plasma Sintering Technique

Maxime Schwertz, Aurelien Katz, Emmanuel Sorrel, Sébastien Lemonnier, Elodie Barraud, Adèle Carrado, Sophie d'Astorg, Anne Leriche, Michel Nardin, Marie-France Vallat, Francis Kosior

This paper deals with the development of a novel and predictive finite element method (FEM) model coupling electrical, thermal, and mechanical time-dependent contributions for simulating the behavior of a powdery material submitted to a spark plasma sintering (SPS) treatment by using COMSOL…

Predictive models of the energy consumption in intelligent buildings

M Fratu, Jean-Paul Becar, Jean-Charles Canonne

In this work we present a novel approach to energy saving in buildings through the identification of the relevant parameters and the application of Soft Computing techniques to generate predictive models of energy consumption in buildings. To verify the feasibility of this proposal, we apply our…

Complete Lagrangian ideal δ(2) submanifolds in the complex projective space : recent advances in the geometry of submanifolds – dedicated to the memory of Franki DILLEN (1963–2013)

Luc Vrancken

In the 1990s B.Y. Chen introduced a sequence of curvature invariants, constructed using appropriate sectional curvatures of the manifold. Each of these invariants is used to obtain an optimal lower bound for the length of the mean curvature vector for an immersion in a real space form. This upper…

PU/PZT composites for vibratory energy harvesting

S. Touhtouh, Mohamed Rguiti, Christian Courtois, F. Belhora, A. Arbaoui, Sophie d'Astorg, A. Rachek, A. Hajjaji

Piezoelectric composites of PU/PZT with 0–3 connectivity were prepared in the film form. Homogeneous dispersion of the ceramic PZT in polyurethane matrix has been obtained and has been verified by SEM analysis. Dielectric properties reveal that under an electrical field of 1000 V the remnant…

A classification of isotropic affine hyperspheres

Marilena Moruz, Luc Vrancken

We study affine hypersurfaces M, which have isotropic difference tensor. Note that, any surface always has isotropic difference tensor. In case that the metric is positive definite, such hypersurfaces have been previously studied in [O. Birembaux and M. Djoric, Isotropic affine spheres, Acta Math.…

Derivatives in noncommutative calculus and deformation property of quantum algebras

Dimitri Gurevich, Pavel Saponov

The aim of the paper is twofold. First, we introduce analogs of (partial) derivatives on certain noncommutative algebras, including some enveloping algebras and their “braided counterparts” — the so-called modified Reflection Equation algebras. With the use of the mentioned derivatives we construct…

Design of C2 algebraic-trigonometric pythagorean hodograph splines with shape parameters

Cindy González, Gudrun Albrecht, Marco Paluszny, Marianela Lentini

In this paper, we construct C2 Algebraic-Trigonometric Pythagorean Hodograph (ATPH) splines by solving a non-linear system of equations in complex variables. We compare these splines, which depend on several shape parameters, with their polynomial PH counterpart as well as with the well-known C2…
