AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We explore invariants as a linking mechanism between the business and technical service perspectives: From the business perspec- tive, invariants can be used to model (business) requirements of an en- terprise; from the technical perspective, invariants ex ...
Depuis plus de 30 ans, Cuba est frappée par une crise économique qui a conduit le pays à une situation de survie permanente provoquant au fil des années une forte dégradation de l'habitat urbain. La municipalité de Centro Habana dans la ville de La Havane ...
The aim of this text is to crystallize the challenges of European railway liberalization for Switzerland, as well as for the railway freight. In order to do that, I will proceed in three steps: I will first recall European railway liberalization. I will th ...
Echo modulations that arise in Carr–Purcell–Meiboom–Gill (CPMG) spin echo sequences and stem from homonuclear couplings can be suppressed by different methods. The evolution under homonuclear couplings can be either ‘‘locked’’ or ‘‘refocused’’, leading to ...
Homogeneous line-widths that arise from transverse relaxation tend to be masked by B-0 field inhomogeneity and by multiplets due to homonuclearf-couplings. Besides well-known spin-locking sequences that lead to signals that decay with a rate R-1p without a ...
Roebel cables are one possible option for use in the manufacture of high current conductors for various technical applications. In this work the behaviour of critical current under transverse loads up to 90 MPa was studied in coated conductor Roebel cables ...
Large fluctuations in the sediment transport rate are observed in rivers, particularly in mountain streams at intermediate flow rates (Ancey, 2006). These fluctuations seem to be, to some degree, correlated with the evolution of morphologies in the stream. ...
We propose an analysis of the social network composed of the characters appearing in Jean-Jacques Rousseau's autobiographic Les Confessions, with existence of edges based on co-occurrences. This work consists of twelve volumes, that span over fifty years o ...
We show that the evolution of magnetic fields in a primordial plasma, filled with standard model particles at temperatures T greater than or similar to 10 MeV, is strongly affected by the chiral anomaly-an effect previously neglected. Although reactions, e ...
Evolutionary algorithms were proposed to automatically find solutions to computational problems, much like evolution discovers new adaptive traits. Lately, they have been used to address challenging questions about the evolution of modularity, the genetic ...
