In this paper we discuss the use of models of space in mixed-reality systems. By model of space we mean a distinguishable geometric or symbolic description associated with a physical space. We outline several types of model that might exist, how they are surveyed or otherwise authored, how they are represented to the users and how the underlying middleware and sensors support them. We show that...

Industrial facilities are becoming increasingly complex, which profoundly affects their planning and operation. Architectural structures, infrastructure and machines are planned using CAD software, but, typically, many alterations are made during actual construction and installation. These alterations usually do not find their way back into the CAD models. In addition, there may be a large body...

Statistical analysis of parasitological data provides a powerful method for understanding the biological processes underlying parasite infection. However, robust and reliable analysis of parasitological data from natural and experimental infections is often difficult where: (1) the distribution of parasites between hosts is aggregated; (2) multiple measurements are made on the same individual h...

CU FOREX is a bilingual hotline for real-time foreign exchange inquiries. Presently, it supports two separate interaction modalities: a direct dialog (DD) interaction, which is systeminitiated for novice users; as well as natural language (NLS) shortcuts, which is u...
