On some curvature conditions of pseudosymmetry type

Ryszard Deszcz, Małgorzata Głogowska, Marian Hotloś, Georges Zafindratafa

It is known that the difference tensor R⋅C−C⋅R and the Tachibana tensor Q(S,C) of any semi-Riemannian Einstein manifold (M,g) of dimension n≥4 are linearly dependent at every point of M. More precisely R⋅C−C⋅R=(1/(n−1))Q(S,C) holds on M. In the paper we show that there are quasi-Einstein, as well…

Dynamic hysteresis and scaling behavior in epitaxial antiferroelectric film

Ge Jun, Ying Chen, Xian-Lin Dong, Denis Remiens, Xin Guo, Fei Cao, Gen-Shui Wang

In this study, we investigated the scaling behavior of dynamic hysteresis with frequency f and electric field E in epitaxial PbZrO3 antiferroelectric film on (111)-oriented SrTiO3 substrate. The scaling relation for the saturated hysteresis loops takes the form of hysteresis area <A> ∝ f 0.03…

Impedance spectroscopy studies on (Na0.5Bi0.5)0.94Ba0.06TiO3 + 0.3 wt% Sm2O3 + 0.25 wt% LiF lead-free piezoelectric ceramics

N. Zidi, Ahcène Chaouchi, Sophie d'Astorg, Mohamed Rguiti, Christian Courtois

The a.c. complex impedance spectroscopy technique was used to obtain the electrical parameters of (Na0.5Bi0.5)0.94Ba0.06TiO3 +0.3 wt% Sm2O3 +0.25 wt% LiF lead-free ceramics in a wide frequency range at different temperatures. These samples were prepared by a high-temperature solid-state reaction…

Human-Machine task allocation: Impact on patient safety in hospital settings, La distribution des tâches entre Homme et Machine : impact sur la sécurité des patients à l’hôpital

Sylvia Pelayo, Romaric Marcilly, Françoise Anceaux, Stéphanie Bernonville, Marie-Catherine Beuscart-Zephir

The paper aims at evaluating the impact of the tasks’ allocation between human and machine on the efficiency of work systems in the healthcare domain. Usability testing was performed to compare two different tasks’ allocations depending on two different systems (semi-automated system vs. manual…, Ce travail s’intéresse à l’impact de l’allocation des tâches entre humain et machine sur l’efficacité des systèmes de travail. Il défend l’idée que la conception d’outils doit être centrée sur l’humain et non pas orientée par la technique. Pour cela, on peut considérer l’humain et la machine comme…

Development of a Platform Dedicated to The TeleMedical Practice under local architecture USB-HID and distant TCP-IP

A. Nemmiche, Mohammed Benabdellah, N. Hamlil, Sofiane Rerbal, Georges Nassar

The telemedical practice consists in taking from patient a multidimensional and multimedia information representative of its physiopathological state, to stream them to a local computer terminal initially then to a distant computer terminal in the second time. We propose through this article : 1)…

Solving the biharmonic Dirichlet problem on domains with corners

Colette De Coster, Serge Nicaise, Guido Sweers

The biharmonic Dirichlet boundary value problem on a bounded domain is the focus of the present paper. By Riesz’ representation theorem the existence and uniqueness of a weak solution is quite direct. The problem that we are interested in appears when one is looking for constructive approximations…

Elasto-viscoplasticity Behaviour of a Structural Adhesive Under Compression Loadings at Low, Moderate and High Strain Rates

David Morin, Grégory Haugou, Franck Lauro, Bruno Bennani, Benjamin Bourel

Crashworthiness performance of automotives by introducing new materials is of high interest based on the global mass’ reduction of cars. Bonded techniques are tested at present with respect to the reduction of the mass/energy’s ratio combined with recycling processes. In this study, a compression…

A hybrid heuristic for the 0–1 Knapsack Sharing Problem

Boukthir Haddar, Mahdi Khemakhem, Said Hanafi, Christophe Wilbaut

The Knapsack Sharing Problem (KSP) is a variant of the well-known NP-hard knapsack problem that has received a lot of attention from the researches as it appears into several real-world problems such as allocating resources, reliability engineering, cloud computing, etc. In this paper, we propose a…
