Given a B-pair W and a Schur functor S, we show under some general assumptions that W is trianguline if and only if S(W) is. This is an extension of earlier work of Di Matteo. We derive some consequences on the behavior of local Galois representations under morphisms of Langlands dual groups. We attach to a Schur functor a map between the trianguline deformation spaces defined by Hellmann, and we study congruence loci on the Hecke-Taylor-Wiles varieties constructed by Breuil, Hellmann and Schraen for unitary groups.

L’utilisation des nouvelles technologies pour transmettre des savoirs. Cette ePublication «La décolonisation: ses enjeux géopolitiques et son impact sur le processus d’intégration européenne» revient sur les grands moments de la désintégration des empires coloniaux européens, avec un accent particulier sur les décolonisations française et britannique, et s’interroge sur l’influence de ce processus de décolonisation sur le processus de construction européenne. Dans un premier temps, elle retrace, à travers des cas précis, les principales étapes de la décolonisation depuis 1945. C’est en effet dans un contexte de guerre froide et de condamnation internationale du colonialisme de plus en plus forte que les populations indigènes vont progressivement se défaire des liens qui les unissent à une Europe exsangue et ruinée par la Seconde Guerre mondiale. Parallèlement, la naissance de l’Europe communautaire amène les métropoles européennes à concilier politique d’outre-mer et politique européenne. Puis, l’entrée sur la scène internationale des pays du tiers-monde entraîne un changement dans les relations entre l’Europe et les (anciennes) colonies et soulève la question d’une politique communautaire d’aide au développement. Dans un deuxième temps, l'ePublication revient donc sur les débats qui ont mené en 1957 à l’association des pays et territoires d’outre-mer (PTOM) à la Communauté économique européenne (CEE), puis à la signature des conventions de Yaoundé (1963) et de Lomé (1975). Un point fort réside dans la collection et l’analyse de plus de 700 ressources documentaires riches et diversifiées, telles que des documents d'archives, des articles de presse, des correspondances, des extraits de mémoires, des photos, des caricatures, etc. [less ▲]

Lattice networks with dissipative interactions can be used to describe the mechanics of discrete meso‐structures of materials such as 3D‐printed structures and foams. This contribution deals with the crack initiation and propagation in such materials and focuses on an adaptive multiscale approach that captures the spatially evolving fracture. Lattice networks naturally incorporate non‐locality, large deformations and dissipative mechanisms taking place inside fracture zones. Because the physically relevant length scales are significantly larger than those of individual interactions, discrete models are computationally expensive. The Quasicontinuum (QC) method is a multiscale approach specifically constructed for discrete models. This method reduces the computational cost by fully resolving the underlying lattice only in regions of interest, while coarsening elsewhere. In this contribution, the (variational) QC is applied to damageable lattices for engineering‐scale predictions. To deal with the spatially evolving fracture zone, an adaptive scheme is proposed. Implications induced by the adaptive procedure are discussed from the energy‐consistency point of view, and theoretical considerations are demonstrated on two examples. The first one serves as a proof of concept, illustrates the consistency of the adaptive schemes and presents errors in energies. The second one demonstrates the performance of the adaptive QC scheme for a more complex problem. [less ▲]

The skills training is organized by the DHH doctoral training unit and will be led by Prof. Andreas Fickers, Dr. Stefania Scagliola and Andy O’Dwyer. It consists of a two-day program, in which lectures and theoretical discussions are combined with hands-on demonstrations and group experiments. The first day is dedicated to literature and to making sketches and drawings of how the digital affects the nature of a historical source. The second day the participants are going to digitize various datatypes and reflect on their observations of this process and the differences between data types. The last part of the training consists of a crowdsourcing experiment in which the genealogy of the term Digital Source Criticism is going to be traced and documented. [less ▲]

Remanufacturing of used technical products allows saving of raw material and energy. The complex and mostly manual disassembly of the products prevents the application of remanufacturing in industry. The fully automated dismantling can not be achieved and the manual work causes high labour costs. Companies can profit by remanufacturing. Using human-robot collaboration for disassembly allows a certain degree of automation and provides the flexibility and knowledge of the human. This is a promising approach to economically realise a disassembly and remanufacturing of products which are difficult to disassemble or have a high variance. [less ▲]

Snow changes from a porous solid to a granular material during deformation with high strain rates. This transition occurs in many cases where snow is relevant to engineering problems (vehicle mobility, avalanche formation and prevention, skiing etc.). For the description of the fast deformation of snow the discrete element method (DEM) is a valuable tool, as it is able to account for both states and the transition between them: the interaction of the loose and bonded particles. For the development of a physically relevant DEM snow model [1] we investigate experimentally along with simulations the basic processes of the granular behavior of snow. In the granular state, sintering plays an important role for the dynamics of the particles. Via sintering the high temperature ice particles (homologous temperature 0.95) bond together and change the structure and the physical properties of the material. This temperature dependent sintering process, which happens in the time range of milliseconds to hours, is in the focus of the present work. The fast sintering of ice in the range of milliseconds has scarcely been investigated. However, from sintering studies with ice cones (radius of 3 mm) we know, that the sintering force is closely related to the contact area of the particles [2]. As the contact area changes considerably for complicated shapes, exhibited by natural snow crystals, we consider different snow types (grain shape and size), besides ice beads as spherical model snow. The latter one is used to exclude shape effects and to directly compare experiments to simulations with spherical particles. To be able to take the effects of the grain shape into account and to examine sintering in the time range of interest (seconds), we perform angle of repose experiments and simulations. Snow is sieved to pile up on a flat base until an angle of equilibrium, the angle of repose, is formed. This angle increases with the sintering of the particles, but also with the inter-particle friction. To analyze the contribution of the friction and the grain shape without sintering, we perform the experiments at a low temperature °C ( 0.87), where sintering can be neglected; thus, the angle of repose is determined by inter-particle friction. With these measurements, we calibrate the simulations. At higher temperatures (up to °C) sintering changes the angle of repose, and a physically relevant sintering law for real snow is established in the simulations. [less ▲]
