. Wstęp

In the thesis computational semantics for monadic quantifiers in natural language in the spirit of J. van Benthem’s works [van Benthem 1986] is considered. The possible correlations between quantifiers and procedures which can be used to compute quantifiers’ denotations in finite models are discussed. We prove M. Mostowski’s theorem that monadic quantifiers definable in the divisibility logic a...

Stilbene Synthase and Chalcone Synthase : Two Different Constitutive Enzymes in Cultured Cells of Picea excelsa.

Cultured cells of Picea excelsa capable of forming stilbenes and flavanoids have been established. Unlike needles of intact plants containing piceatannol (3,3',4',5-tetrahydroxystilbene) and stilbene glycosides the cultured cells converted phenylalanine and p-coumaric acid primarily into resveratrol monomethyl ether (3,4'-dihydroxy-5-methoxystilbene) and naringenin. Partially purified enzyme pr...

Gestion de la variabilité dans les applications SaaS multi-locataire

Multi-tenancy is a relatively new software architecture principle, generally adopted when a software application is provided as a service (SaaS). Such new principle reduce considerably the application deployment and maintenance costs, as all customers(tenants) share the same instance of such application. However, to attract a significant number of tenants, the application has to be customizable...

Variabilité des performances des outils de TAL et genre textuel

RÉSUMÉ. Nous rapportons dans cet article un ensemble de résultats liés à la mise au point d’une base de marqueurs de relations lexicales pour un outil d’aide à la réalisation d’ontologies à partir de textes, CAMÉLÉON. L’évaluation de ces patrons sur huit corpus différents montre une grande variation de leurs performances selon le corpus testé. Cela nous conduit à deux sortes de conclusions : 1....
