This paper describes our recent work in developing multilingual spoken language systems that support human-computer interactions. Our approach is based on the premise that a common semantic representation can be extracted from the input for all languages, at least within the context of restricted domains. In our design of such systems, language dependent information is separated from the system...

Voyager 1 is observing the energy spectra of anomalous cosmic ray H, He, and O in the heliosheath. The relative abundance of H/He is 20 at 1-1.5 MeV/nuc, indicating that H pickup ions are more efficiently accelerated than was modeled from observations at higher energies. Voyager 2 began observing upstream energetic ions from the shock in late 2004 at ∼75 AU, about 10 AU closer to the Sun than o...

Based on Voyager 2 observations, a numerical model of the heliosphere, which includes the mutual interaction of the interstellar medium, solar wind plasma, and interstellar hydrogen, is employed to speculate on the possible crossing of the termination shock by the Voyager spacecraft. The multiple crossings caused by large-scale solar wind uctuations are studied quantitatively. In the event that...

The authors are developing a series of intelligent software agents, collectively referred to as AgentsTools, for the express purpose of aiding those involved in the establishment, execution, and monitoring of distributed simulations, including HLA/RTI compliant simulations AgentsTools are being prototyped in a Phase I SBIR program for STRICOM using Java, Java’s RMI (Remote Method Invocation) ex...
