Guaranteed Quantity of Interest Error Estimate Based on Equilibrated Flux Reconstruction

Zuqi Tang, Suyang Lou, Abdelkader Benabou, Emmanuel Creusé, Serge Nicaise, Julien Korecki, Jean-Claude Mipo

The quality of a local physical quantity obtained by the numerical method, such as the finite element method (FEM), attracts more and more attention in computational electromagnetism. Inspired by the idea of goal-oriented error estimate given for the Laplace problem, this work is devoted to a…

Four dimensional biharmonic hypersurfaces in nonzero space forms have constant mean curvature

Zhida Guan, Haizhong Li, Luc Vrancken

In this paper, through making careful analysis of Gauss and Codazzi equations, we prove that four dimensional biharmonic hypersurfaces in nonzero space forms have constant mean curvature. Our result gives the positive answer to the conjecture proposed by Balmuş–Montaldo–Oniciuc in 2008 for four…

Flash point prediction with UNIFAC type models of ethylic biodiesel and binary/ternary mixtures of FAEEs

Débora Costa Do Nascimento, Natália Daniele Dorighello Carareto, Antonio Marinho Barbosa Neto, Vincent Gerbaud, Mariana Conceição da Costa

In order to guarantee safe handling of a combustible liquid, such as biodiesel, it is important to be aware of its Flash Point (FP). Thus, the present study focused on FP experimental measurement and thermodynamic correlation of binary and ternary mixtures of saturated or unsaturated fatty acid…

Modification of hydroxyapatite surface properties by electron irradiation

Guillaume Bai, Jean-Christophe Hornez, Ulrich Maschke, Philippe Supiot, Etienne Bres

In the present work, the modification of wetting properties of EB irradiated HA ceramics are studied under air and N2 gas atmospheres. We show a noticeable increase of the hydrophily of electron irradiated HA ceramics in an air atmosphere and a lesser increase when the samples are irradiated in an…

Hyperbolic Radial Spanning Tree

Lucas Flammant

We define and analyze an extention to the d-dimensional hyperbolic space of the Radial Spanning Tree (RST) introduced by Baccelli and Bordenave in the two-dimensional Euclidean space (2007). In particular, we will focus on the description of the infinite branches of the tree. The properties shown…

Impedance spectroscopy analysis and piezoelectric properties of (Na 0.5 Bi 0.5 ) 0.94 Ba 0.06 TiO 3 + 0.3wt.% Sm 2 O 3 lead-free ceramics sintered at different conditions

Sadia Kennour, Nouara Lamrani-Amaouz, Ahcène Chaouchi, Mohamed Rguiti, Yannick Lorgouilloux, Christian Courtois

(Na0.5Bi0.5)0.94Ba0.06TiO3 + 0.3 wt.% Sm2O3 (named NBT-BT) lead-free piezoelectric ceramics were prepared by normal sintering. The effect of atmosphere sintering on NBT-BT ceramics was investigated through X-ray diffraction, dielectric, ferroelectric and piezoelectric characterizations. Real (Z′)…
