A number of applications are available that are designed to enhance student engagement in the classroom through the use of Tablet PCs. The value of this goal is well documented, and researchers working with applications such as Classroom Presenter and DyKnow Vision have blazed the way in studying not only how best to deploy this technology, but also how to best teach with it in actual classroom...

The use of workflow models to integrate intelligently complex experimental and analytical processes is becoming more and more critical to support scientific discovery. Storing and providing querying capabilities to retrieve, import, re-use, adapt, and reason about workflows are becoming necessary components to workflow architectures supporting collaborative and translational research. We report...

This position-paper accompanies the paper entitled “Recording techniques for capturing natural every-day speech“, which is published in the LREC-2002 proceedings, and puts forward our current thinking for the recording and storage of large amounts of every-day conversational speech. There has been considerable discussion recently regarding the optimal choice of media for recording, and the prob...

In the UIMA text annotation framework the most common way to store annotated documents (CAS) is by serializing the document to XML and storing this XML in a file in the file system. We present a framework to store CASes as well as their type systems in a relational database. This does not only provide a way to improve document management but also the possibility to access and manipulate selecti...

Arguably, the most successful data structure for tabling is tries. However, while tries are very efficient for variant based tabled evaluation, they are limited in their ability to recognize and represent repeated answers for different calls. We propose a new design for the table space where all tabled subgoal calls and tabled answers are stored in a common global trie instead of being spread o...

Relational databases are often used as a basis for persistent storage of ontologies to facilitate rapid operations such as search and retrieval, and to utilize the benefits of relational databases management systems such as transaction management, security and integrity control. On the other hand, there appear more and more OWL files that contain ontologies. Therefore, this paper proposes to ex...

New experiences can be memorized by modifying the synaptic efficacies. Old memories are partially overwritten and hence forgotten when new memories are stored. The forgetting rate depends on the number of synapses which are modified: networks in which many synapses are highly plastic and hence change following each experience, are good at storing new memories but bad at retaining old ones. On t...

We investigate the statistical mechanics of a torsionally constrained polymer. The polymer is modeled as a uctuating rod with bend sti ness AkBT and twist sti ness CkBT . In such a model, thermal bend uctuations couple geometrically to an applied torque through the relation Lk = Tw+Wr. We explore this coupling and nd agreement between the predictions of our model and recent experimental results...
