Comment les sociétés ont-elles fait face aux fortes augmentations de dette publique ? Dans l’histoire européenne des trois derniers siècles, ces moments ont eu lieu surtout pendant et après guerres, à l’exception notable la fin du xixe siècle xxe siècle. Ces conséquences contrastées fois en matière macroéconomiques ter...

Collective phenomena in biology can be a source of inspiration to propose multiagents methods in problem solving. They allow the design of individual behavior that are simple and that produce collectively complex phenomena. This article presents the process we followed to transpose a simulation model to a problem solving one. The initial biological context is the web building in social spider s...

This article aims to study how mapping contributes to organize and implement Integrated Coastal Zone Management projects. In order to observe the use of spatial representations and better understand the stakeholder’s mapping practices a qualitative methodology is used. The results show that mapping was mostly used to structure and stabilize the actor’s network. MOTS-CLES : représentations spati...

________________________________________________________________________________________________________ Fine granularity scalable speech coding: Application to the G.729 coder This paper proposes an efficient codebook design for tree-structured vector quantization (TSVQ) which is embedded in nature. We modify the speech coding standard G.729 by replacing its original quantizer for line spectra...

This paper describes the main retrieval problems when facing with blogs. Using the classical tf idf vector-space model together with three probabilistic and one statistical language model, we evaluate them using a TREC test-collections composed of 100 topics. Using two performance measures, we show that ignoring a stemming approach results in a better performance than other indexing strategies ...

We prove that in the weak topology of measure preserving transformations , a dense G has purely singular continuous spectrum in the orthocomplement of the constant functions. In the uniform topology, a dense G of aperiodic transformations has singular continuous spectrum. We show that a dense G of shift-invariant measures has purely singular continuous spectrum. These results stay true for Z d ...

VIVO is an open source tool from semantic web technologies, used to identify and characterize the research activity of an institution. It allows the reuse of information or data existing in several external reference bases and different bibliographic databases. The aim is to collect and use four sets of relevant data on research activity: research structures, authors, research outputs and means...

This work evaluates quotation finding approaches in the context of ancient Greek documents. We explore the notion of quotation as relevant to the first centuries of our era, and we discuss the efficiency and usability of unsupervised approaches, both statistical and semantic, used in more modern cases. We also discuss some characteristics of our corpus relatively to performance metrics. MOTS-CL...

________________________________________________________________________________________________________ When nasal is more than nasal: Oral articulation of French nasal vowels Lingual and labial articulations of oral and nasal vowels of three Metropolitan French (FM) speakers were recorded using an EMA system. Inter-speaker variation in these oral articulations suggest that the role of motor e...
