The Oz Explorer [Sch97] is a visual constraint programming tool for Oz. Oz is a concurrent constraint language providing for functional, object-oriented, and constraint programming [Smo95]. It has a simple yet powerful computation model which extends the concurrent constraint model by first-class procedures, concurrent state and encapsulated search. The Explorer uses the search tree of a constr...

The Allen Brain Atlas is a repository of neuroanatomical data concerning the mouse brain. The core of the database is a Nissl-stained reference atlas of the brain accompanied by in situ hybridization data for essentially the entire mouse genome. This database is freely available at the Allen Institute for Brain Science website, as is an innovative tool to explore the database, the Brain Explore...

Dans cet article, nous proposons une nouvelle piste de raisonnement élaborée en interdisciplinarité avec des archéologues, conçue pour études liées à la notion mobilité. À l’aide d’études cas, analysons comment les chercheurs ont identifié, conceptualisé et relié traces matérielles décrivant divers processus mobilité dans région donnée. Nous élaborons ensuite construction d’ontologies qui perme...

The Explorer bar is a component of the Internet Explorer web browser that provides a unified model for web navigation activities. The user tasks of searching for new sites, visiting favorite sites, and accessing previously viewed sites are simplified and enhanced by using a single user interface element.

The CTSA Inventory of Resources Explorer facilitates searching and finding relevant biomedical resources in this rich, federated inventory. We used efficient and non-traditional formal usability methods to define requirements and to design the Explorer, which may be extended to similar web-based tools.

We envision a scenario with robots moving on a terrain represented by a plane. A mobile robot, called explorer is connected by a communication chain to a stationary base camp. The chain is expected to pass communication messages between the explorer and the base camp. It is composed of simple, mobile robots, called relays. We are investigating strategies for organizing and maintaining the chain...
