IN 1973, ARTHUR MCANALLY AND ROBERTDOWNSauthored a seminal article on the changing role of the university library director. This article takes a look at McAnally and Downs’s findings twenty years later to determine whether the changes outlined in 1973 are still valid today. Additional sources of strife for university library directors are outlined and requirements for today’s library directors ...

Multimedia searching over Internet has gained substantial popularity in the past two years. Java's networking features, along with the growing number of Web browsers that can execute Java applets, facilitate distributed processing. Networking and computational performances are key concerns when considering the use of Java to develop performance-sensitive distributed multimedia search engines. T...

In the present paper, a numerical method is considered for solving one-dimensional heat equation subject to both Neumann and Dirichlet initial boundary conditions. This method is a combination of collocation method and radial basis functions (RBFs). The operational matrix of derivative for Laguerre-Gaussians (LG) radial basis functions is used to reduce the problem to a set of algebraic equatio...

The UQMG group submits three runs for instance search at TRECVid 2015 [13]: all of them are automatic runs. Instead of adopting the traditional retrieval approach, e.g., Bag-of-Visual-Word (BoVW), our approach consists of three major steps: video decomposition, feature extraction and indexing. During decomposition, video segmentation is applied and various objects are extracted. Here a visual o...

We formulate the static mechanical coupling of a geometrically exact Cosserat rod to a nonlinearly elastic continuum. In this setting, appropriate coupling conditions have to connect a one-dimensional model with director variables to a three-dimensional model without directors. Two alternative coupling conditions are proposed, which correspond to two different configuration trace spaces. For bo...

RÉSUMÉ. Dans les systèmes temps réel manipulant des tâches périodiques, des travaux introduisant la notion de contraintes (m,k)-firm ont été effectués. Ces contraintes permettent de relaxer les contraintes temps réel des tâches en autorisant que certaines invocations d’une tâche soient perdues. D’un autre côté, dans les SGBD temps réel, certaines transactions périodiques permettent, de rafraîch...

RÉSUMÉ. Le développement des systèmes de gestion de contenu a profondément changé la nature du web : de plus en plus de documents sont créés automatiquement et leur mise en page reflète leur structure logique. Dans ce travail, nous montrons que l’information contenue dans la mise en page est suffisante pour inférer une structure sémantiquement riche, ce qui ouvre la voie à de nombreuses applica...

The MISE Project (Mediation Information System Engineering) aims at providing virtual enterprises with a Mediation Information System (MIS) in charge of supporting interoperability in a collaborative network. MISE proposes an overall MIS design method according to a model-driven approach, based on model transformations. This MIS is in charge of (i) information management, (ii) services sharing ...
