Grr obner basis are a powerful tool with many applications in symbolic computation. In this article, we describe a linear systolic array which can be used as coprocessor for eecient computation of Grr obner basis. It was designed by synthesis from the high-level speciication language Alpha. Un r eseau systolique lin eaire pour le calcul de bases de Grr obner R esum e : Les bases de Grr obner so...

We study how the underlying graph of dependencies of one dimensional cellular automaton may be used in order to move and compose areas of computations. This allows us to deene complex cellular automata, relaxing in some way the inherent synchronism of such networks. and asynchronous computations. R esum e Nous etudions comment le graphe sous-jacent de d ependances d'un automate cellulaire de di...

We complete the theory of velocity averaging lemmas for transport equations by studying the limiting case of a full space derivative in the source term. Although the compactness of averages does not hold any longer, a speciic estimate remains, which shows compactness of averages in more general situations than those previously known. Our method is based on Calderon-Zygmund theory. R esum e Nous...

En croisant regards d’historiens et d’economistes, ce numero de la Revue l’OFCE a souligne richesse pluralite des lectures qui peuvent etre tirees 100 ans apres promulgation du Traite Versailles. Faire un bilan sous forme lecon definitive tiree l’histoire est exercice ardu : l’un ecueils majeurs provient point dans le temps partir duquel on choisit d’analyser passe. Par exemple si, comme il cou...

This multi-case study explored Swedish military veterans’ experiences related to posttraumatic stress disorder, moral injury, and spiritual injury. Specifically, the present focused on 4 domains (health care, veteran’s administration, conflicts injuries, identities existential dimensions) that emerged in participants’ meaning making as they navigated everyday life. While these...

Lencephalopathie de Wernicke est causee par une carence severe en thiamine il surtout observe chez les patients alcooliques, Nous rapportons le cas dune femme 34 ans a 10 SA, avec hyperemesisgravidarum severe. Elle presente confusion surdite bilaterale brutale crise convulsive tonico-clonique . Limagerie magnetique resonance montreun aspect faveur dun syndrome Gayet-Wernicke, sur vitaminique de...

This paper presents procedures for estimating the parameters of a regulated firm's production function which explicitly model the impact of the private information possessed by utility in the regulatory process. The paper derives the optimal regulatory outcome for two cases: (1) the utility's private information is observable by the regulator and (2) only the distribution of the private informa...

Asterisk* is a test bed system designed to support the development of new kinds of splines. The key concept is the integration of symbolic computation facilities with tools for interactively modifying and comparing different splines. By mode ling a spline as a list of attributes, Asterisk* can be used to create and manipulate almost any spline, without making assumptions about the future direct...
