Project Voyager builds applications that link virtual services to people, places, and things. This thesis describes the design and implementation of two such systems. The MIT Campus Guide application provides services for specific points of interests. Campus visitors used the system to interact with different sites—for example, a restaurant, a lecture hall, or a sculpture. The Voyager Personal ...

This paper reviews solar wind observations in the outer heliosphere, concentrating on new developments in the past 3 years. Voyager 2 has detected an increase in speed and decrease in normalized density, consistent with spending more time in the fast polar ow as it moves to higher heliolatitudes. The proton temperatures continue the increase which began at about 35 AU. We describe a new feature...

This paper describes our initial efforts at porting the VOYAGER spoken language system to Japanese. In the process we have reorganized the structure of the system so that language dependent information is separated from the core engine as much as possible. For example, this information is encoded in tabular or rule-based form for the natural language understanding and generation components. The...

Introduction The VOYAGER speech recognition system, which was described in some detail at the last DARPA meeting [9], is an urban exploration system which provides the user with help in locating various sites in the area of Cambridge, Massachusetts. The system has a limited database of objects such as banks, restaurants, and post offices and can provide information about these objects (e.g., ph...

We present evolutionary sequences for Jupiter and Saturn, based on new nongray model atmospheres, which take into account the evolution of the solar luminosity and partitioning of dense components to deeper layers. The results are used to set limits on the extent to which possible interior phase separation of hydrogen and helium may have progressed in the two planets. When combined with static ...

Massively parallel processors introduces new demands on software systems with respect to performance , scalability, robustness and portability. The increased complexity of the memory systems and the increased range of problem sizes for which a given piece of software is used poses serious challenges for software developers. The Connection Machine Scientiic Software Library, CMSSL, uses several ...
