iv Résumé (Solution de guidage navigation pilotage pour véhicules autonomes hétérogènes en vue d'une mission collaborative) L'application classique des techniques d'estimation et de contrôle, ba– sées sur des capteurs de haute performance, à des systèmes utilisant des capteurs de performances médiocres mais adaptés aux besoins nouveaux des troupes légères et à leurs contraintes est un enjeu pou...

We have investigated how four different pour point depressant (PPD) polymers affect the pour point transition in mixtures of a single pure wax in a solvent. We used either n-eicosane (C20), CH3(CH2)18CH3, n-tetracosane (C24), CH3(CH2)22CH3 or n-hexatriacontane (C36), CH3(CH2)34CH3 as the wax component with either n-heptane or toluene as the solvent component. For all wax-solvent combinations, t...

this paper investigates the effect of different methods of carbon nanotubes distribution in a thin matrix on static and dynamic behavior of the nanocomposite. five different symmetric patterns of distribution are considered, including four parabolic patterns and a linear one. for each pattern, the effective mechanical properties of the resultant nanocomposite are calculated using the rule of mi...

A disposable kit was tested as a means of detecting significant bacteriuria by quantitative culture of urine. The total error in 3,563 specimens tested by five investigators was less than 1%. The method was very effective in differentiating significant bacteriuria, i.e., more than 100,000 bacteria per ml of urine from uninfected urine. In specimens from patients with urinary tract abnormalities...

Le (bon) séquencement des événements au fil du temps est un sujet important pour l’analyse de programmes, par exemple dans le cadre de protocoles d’échange d’information ou de systèmes embarqués. De nombreux travaux s’appuient sur la logique temporelle linéaire (LTL) pour décrire formellement le comportement attendu d’un programme, sous la forme d’une succession d’actions distinctes. Implanté a...

Résumé. Le système CORON est une plate-forme générique de fouille de données qui propose une très grande collection d’algorithmes standards et “maison” pour l’extraction de motifs et de règles d’association. Le système a été utilisé dans des domaines et applications très variés, et offre une panoplie de modules utilisables avec profit par un analyste lors de sa recherche de pépites dans les don...

Here, we describe a numerical method which combines a mixed nite volume//nite element formulation on unstructured triangulations and a linearized implicit method for time advancing. A particular attention has been paid to the source term implicitation. This method is applied to three typical low-Reynolds number k ? " models, namely those of Lam-Bremhorst, Nagano-Tagawa and Speziale-Abid-Anderso...

Plastic waste can be seen in several areas the Wonorejo mangrove forest, Surabaya, which is also a habitat for various types of microbes. Research on bacterial isolates from water samples forests needs to conducted determine their diversity. This research was diversity and dominance forest waters. Each sample taken site that regularly irrigated (station 1) flooded 2). The number bacteria determ...

Autonomic computing has been proposed recently as a way to address the difficult management of applications whose complexity is constantly increasing. Autonomous applications will have to be especially flexible and be able to monitor themselves permanently. This work presents a framework, Pandora, which eases the construction of applications that satisfy this double goal. Pandora relies on an o...

JAMUS (Java Accommodation of Mobile Untrusted Software) is a Java platform dedicated to the accommodation of untrusted programs that can specify their requirements regarding the resources available on the system. It relies on the principle of resource contracting in order to offer a certain level of quality of service to hosted programs, while ensuring a safe execution of these programs at runt...
