In this paper we study the problem of scheduling a collection of workflows, identical or not, on a SOA grid. A workflow (job) is represented by a directed acyclic graph (DAG) with typed tasks. All of the grid hosts are able to process a set of task types with unrelated processing costs and are able to transmit files through communication links for which the communication times are not negligibl...

Background: Cystic echinococcosis (CE), as a chronic parasitic disease, is a major health problem in many countries. The performance of the currently available serodiagnostic tests for the diagnosis of CE is unsatisfactory. Objective: The current study aimed at sub-cloning a gene, encoding the B8/1 subunit of antigen B (AgB) from Echinococcus granulosus, using gene optimization for the immunodi...

Oscillating chemical bulk reactions of the Belousov–Zhabotinsky (BZ) type usually show a welldefined periodical color change representing the underlying chemical reactions. Models including up to more than 50 coupled reactions have been developed to describe the BZ-reaction in detail, however, typically a much simpler set of equations is used (i.e. the Brüsselator, the FKN, or the FitzHugh–Nagu...

Résumé. Plusieurs méthodes ont été développées ces dernières années pour détecter, dans un réseau social, les membres qualifiés, selon les auteurs, d’influenceurs, de médiateurs, d’ambassadeurs ou encore d’experts. Dans cet article, nous proposons un nouveau cadre méthodologique permettant d’identifier des diffuseurs dans le contexte où seule l’information sur l’appartenance des membres du rése...

Résumé. L’analyse discriminante généralisée suppose que l’échantillon d’apprentissage et l’échantillon test, qui contient les individus à classer, sont issus d’une même population. Lorsque ces échantillons proviennent de populations pour lesquelles les paramètres des variables descriptives sont différents, l’analyse discriminante généralisée consiste à adapter la règle de classification issue d...

Purpose – Aims to assess the effect of European Union performance directives related to CE marking on the machinery industry of Taiwan. Design/methodology/approach – This paper adopts a questionnaire to collect information. By means of a statistical scheme, performance indices of importance and difficulty, which meet the directives requirement, are designated. The performance evaluation matrix ...

Background: We performed this study in order to investigate the role of chronic endometritis (CE) in unexplained recurrent spontaneous abortion (RSA) and to determine the correlation between hysteroscopic and histologic findings of CE in patients with unexplained RSA. We also tried to find out the relation between CE and primary vs. secondary RSA. Materials and Methods: One hundred and forty-two ...
