We describe an approach to modeling diagnostic problems that is based on a passive observation of a diagnostician's work-flow and recording their findings and final diagnosis, from which the model can be modified directly, or improved by learning from cases so acquired. While the probabilistic model of a system under diagnosis is necessarily simplified,(More)
In this paper we discuss the implementation of receiver-driven rate adaptation using multicast and SNR scalability as supported by Version 2 of ITU-T Recommendation H.263-Video Coding for Low Bit Rate Communication. We compare the layered bit stream approach to receiver-driven rate adaptivity to the approach using multiple independent bit streams. We show(More)
Communication is vital in any workplace. However, as workers become less tied to their desktops and computers, the need to provide them with a flexible, easy to use, mobile method of communication becomes more necessary. This is particularly true in " non-traditional " workplaces like factories or hospitals. Cell phones, PDA's, and walkie-talkies provide(More)

Communication is an integral task for any distributed work group. As the work environment becomes less structured, it becomes harder for teams who are not collocated to coordinate and communicate about essential matters that might be integral to their productivity. More often than not, communication is not the only task an individual is engaged in, but one(More)
In looking forward to more natural telecollaboration, we can anticipate that the teleconferencing system of the future will enable participants at distant locations to share the same virtual space. The visual object of each participant can be transmitted to the other sites and be rendered from an individual perspective. This thesis presents an effort,(More)
