Abstract:
Au cours des dernières années, de nombreux concepts de structures spatiales dépliables ou gonflables constituées de membranes de grande dimension ont vu le jour. Cependant, les films minces de faible épaisseur utilisés dans ces réalisations se plissent lorsqu’ils sont soumis à des contraintes de compression. L’existence de plis sur ces surfaces peut affecter la performance de certains dispositifs jusqu’à les rendre totalement inutilisables. C’est la raison pour laquelle la prédiction de l’apparition des zones plissées et de leur géométrie est un axe de recherche important pour les acteurs de l

Abstract:
This master’s research is a phenomenological inquiry into the pedagogical moment in teacher education. This phenomenon is explored through a conceptual lens that draws from the phenomenological pedagogical ideals that are intrinsic to the work of both Ted Aoki and Max van Manen. Following a comprehensive outline of the phenomenological methodology that guides this thesis, the pedagogical moment is described in terms of three phases: tension, opening and pulse. The phenomenon is further explored through several sub themes relating to the lifeworld existentials (time, body, space, relation to ot

Ce travail est lié au système de protection des réseaux de distribution. Les réseaux radiaux dedistribution peuvent être protégés simplement par une protection placée en tête du départ. Maisl'exploitation future des réseaux de distribution, qui se transforment en réseaux intelligents,flexibles et adaptatifs, va sûrement nécessiter une protégeabilité plus complexe. Parconséquent, un nouveau plan de protection pourrait être nécessaire afin d'augmenter la fiabilitédu réseau de distribution et le taux de productions décentralisées.

The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. For the tensile properties, it is the inherent heterogeneity of the paperboard that might cause problems for the board-maker.

Abstract:
Lors de la réalimentation des auxiliaires d'une tranche nucléaire ou hydraulique, l'étape la plus à risque est la remise sous tension brusque du transformateur à cause des surtensions et courants d'appels générés. Ces phénomènes transitoires engendrent des effets très indésirables autant pour le réseau comme pour le transformateur (efforts électrodynamiques sous les bobinages, vibration du circuit magnétique, bruit et vieillissement prématuré du transformateur.) Le but de ces travaux de thèse est de proposer de nouvelles méthodologies permettant d'évaluer les paramètres mal connus (les valeurs

Abstract:
O objetivo deste trabalho é apresentar um modelo para análise probabilística de estruturas de concreto armado, sob estado plano de tensão, através do método dos elementos finitos. O modelo permite mostrar como as incertezas presentes nos principais parâmetros do comportamento de vigas e pilares afetam a variabilidade da resposta destas estruturas. Inicialmente é desenvolvida, através do Princípio dos Trabalhos Virtuais, uma formulação para análise não-linear física e geométrica de estruturas, submetidas a um estado plano de tensão, utilizando-se a formulação Lagrangeana Total.

Abstract:
L'un des aspects important de la conception et de l'exploitation des grands réseaux de transport et d'interconnexion est le maintien de la sécurité du système. Cette sécurité concerne aussi bien les limites thermiques sur les ouvrages de transport que les limites de tension aux noeuds du réseau (contraintes d'isolation et de stabilité). A cet effet, le développement de méthodes nouvelles qui permettront à l'opérateur d'exploiter le réseau de façon à ce qu'aucun incident ne puisse causer les dépassements de limites de sécurité du système, est de plus en plus une nécessité.

Abstract:
Studiens övergripande syfte är att kartlägga lärares syn på bedömningskompetens. En långsiktig intention är även att synliggöra lärares kompetensutvecklingsbehov inom bedömningsområdet. Processen vägleddes av en frågeställning gällande de kunskapsbehov som synliggörs i lärares diskussioner. Forskning har visat att elever lär sig det som de blir bedömda på vilket kan innebära att bedömningen snarare än styrdokument bestämmer vad och hur elever lär. Detta betyder att kunskap om bedömningsprocesser är viktigt och studien relaterar klassrumsbedömning till forskning samt politiskt genomförda reform

Dans le présent travail, nous abordons une problématique essentielle liée aux accessoires des lignes électriques et plus particulièrement au connecteur à perforation d’isolant (TTDC 45501 FA), commercialisé par la société Sicame située à Arnac-Pompadour (Corrèze). Ce produit permet d’effectuer des dérivations de courant en moyenne tension gainé HTA entre 15 et 25kV. Cependant, il devient nécessaire de concevoir une nouvelle génération de connecteurs capable de fonctionner à une tension de 52 kV en raison de la constante augmentation des besoins en électricité.
