Upgradable system opportunities in order to rationalize materials

Part of: Seliger, Günther (Ed.): Innovative solutions : proceedings / 11th Global Conference on Sustainable Manufacturing, Berlin, Germany, 23rd - 25th September, 2013. - Berlin: Universitätsverlag der TU Berlin, 2013. - ISBN 978-3-7983-2609-5 (online). - http://nbn-resolving.de/urn:nbn:de:kobv:83-opus4-40276. - pp. 96–101.Design of more sustainable products is a fundamental priority in our society. New opportunities for facilitating the dissemination of the remanufacturing approach or the Product-Service Systems, or for increasing the lifetime of product (three ways for rationalizing of materials) are proposed by the integration of upgrades, functional enrichments brought to the product. This paper aims to show the need of product upgradability through a concrete study focused on four hypotheses: • H1- Upgradability concept requires a potential of disposed devices which still works. • H2- Upgradability concept requires a need for adaptability of product towards user needs. • H3- Upgradability concept requires a need for adaptability of product versus the competition. • H4- Upgradability concept is consistent with an accumulation of problems. The first results show the necessity to consider a new sort of "evolutionary" products for sustainability: Innovations with multiples upgrade cycles

Claudia Jullien, Dictionnaire de la Bible dans la littérature française. Figures, thèmes, symboles, auteurs

Il s’agit d’un ouvrage de vulgarisation, qui s’appuie, pour ses références bibliques (et certains commentaires), sur la traduction française de la Bible dans la collection de la Pléiade. La théorie documentaire est exploitée – un peu maladroitement –, p. 167, à propos des noms de « Dieu », et p. 237. L’indication des termes hébreux, grecs ou latins pour les termes français correspondants, ou celle de la forme biblique des noms propres francisés constituant une entrée est en général trop irrég..

Low Voltage Totally Free Flexible RF MEMS Switch With Anti-Stiction System

This paper concerns a new design of RF MEMS switch combined with an innovative process which enable low actuation voltage (<5V) and avoid stiction. First, the structure described with principal design issues, the corresponding anti-stiction system is presented and FEM simulations are done. Then, a short description of the process flow based on two non polymer sacrificial layers. Finally, RF measurements are presented and preliminary experimental protocol and results of anti-stiction validation is detailed. Resulting RF performances are -30dB of isolation and -0.45dB of insertion loss at 10 GHz.Comment: Submitted on behalf of EDA Publishing Association (http://irevues.inist.fr/handle/2042/16838

Les réécritures poétiques de l'histoire de Jonas au xvie siècle et la poétique réformée

La figure biblique de Jonas est un révélateur du potentiel de la poétique réformée au xvie siècle. Si Jonas reste une préfiguration typologique du Christ et de la rédemption, son cantique donne lieu à des paraphrases lyriques permettant une appropriation personnelle et collective de la figure de l'élu sauvé, dans le cadre d'une nouvelle herméneutique biblique et de la poétique issue de Marot et de Bèze. Par ailleurs, Jonas est également valorisé comme porteur de la Parole de Dieu et prophète ultime de la pénitence. Aubigné achève de transformer le scénario calvinien de la vocation divine à une fonction prophétique, récusée puis assumée par l'élu, en un nouveau type humain complexe, typiquement réformé, et qui est à la fois un prophète élu et un prédicateur-poète.The biblical character of Jonas is an eloquent example of the scope of reformed poetics in the 16th century. While Jonas is still typologized as a harbinger of Christ and the redemption, his prayer gives rise to lyrical retellings which are at once a personal and a collective appropriation of the figure of the man chosen for salvation, within a new form of biblical hermeneutics combined with poetics inherited from Marot and Beza. Jonas is equally celebrated as the bearer of the Word of God, and as the foremost prophet of penitence. Aubigné succeeded in transforming the Calvinist scheme of divine vocation, with a prophetic function that the chosen one first challenges then faces up to, into a complex human portrait which is both original and typically reformed, in which God's chosen prophet is also a poet with a preaching mission

An asymptotic non-linear model for thin-walled rods

In this paper, we present a non-linear one-dimensional model for thin-walled rods with open strongly curved cross-section, obtained by asymptotic methods. A dimensional analysis of the non-linear three-dimensional equilibrium equations lets appear dimensionless numbers which reflect the geometry of the structure and the level of applied forces. For a given force level, the order of magnitude of the displacements and the corresponding one-dimensional model are deduced by asymptotic expansions

A 2D micromechanical modelling of anisotropy in granular media

We propose a two-dimensional modelling of the anisotropy of granular media based on the use of a second order or a fourth order fabric tensor describing the distribution of the contact probability. This fabric tensor-based approach is then combined with a new kinematic localization rule and yields an efficient homogenization scheme for anisotropic granular media
