Recent progress in inverse methods in France

Given the current level of jet engine performance, improvement of the various turbomachinery components requires the use of advanced methods in aerodynamics, heat transfer, and aeromechanics. In particular, successful blade design can only be achieved via numerical design methods which make it possible to reach optimized solutions in a much shorter time than ever before. Two design methods which are currently being used throughout the French turbomachinery industry to obtain optimized blade geometries are presented. Examples are presented for compressor and turbine applications. The status of these methods as far as improvement and extension to new fields of applications is also reported

10041 Abstracts Collection -- Perspectives Workshop: Digital Social Networks

From 24.01.2010 to 29.01.2010, the Dagstuhl Seminar 10041 ``Perspectives Workshop: Digital Social Networks\u27\u27 was held in Schloss Dagstuhl ~--~ Leibniz Center for Informatics. During the seminar, several participants presented their current research, and ongoing work and open problems were discussed. Abstracts of the presentations given during the seminar as well as abstracts of seminar results and ideas are put together in this paper. The first section describes the seminar topics and goals in general. Links to extended abstracts or full papers are provided, if available

Processing Link Structures and Linkbases on the Web

Hyperlinks are an essential feature of the World Wide Web, highly responsible for its success. XLink improves on HTML's linking capabilities in several ways. In particular, links after XLink can be "out-of-line" (i.e., not defined at a link source) and collected in (possibly several) linkbases, which considerably ease building complex link structures

Composite Event Queries for Reactivity on the Web

Reactivity on the Web is an emerging issue. The capability to automatically react to events (such as updates to Web resources) is essential for both Web services and Semantic Web systems. Such systems need to have the capability to detect and react to complex, real life situations. This presentation gives flavours of the high-level language XChange, for programming reactive behaviour on the Web
