Large three-dimensional virtual space and walk-through animations are used in navigation systems, games, and movies, etc . In three-dimensional space using the CG data, reality is dependent on the texture quality of buildings. However, the costs for high -quality texture data are also high , which makes it very difficult to reproduce the reality of the real world completely. In this research , ...

Spoken dialogue systems have until recently upheld the simplifying assumption that the conversation between the user and the system occurs in a strict turn-by-turn fashion. In order to have more human-like, uent conversations with computers, a new generation of spoken dialogue systems has arisen that is capable of processing the user’s speech in an incremental way. As the user is speaking, the ...

A fast gate module has been developed at KEKB, which can pick up a signal of one bunch along a bunch train. The gate module was attached to a tune measurement system and to a turn-by-turn beam-position monitor system. Continuous monitoring of the betatron tune is an indispensable tool to keep the machine in a stable condition. A measurement of the tune along a bunch train is helpful to estimate...

People in dialog use a rich set of nonverbal behaviors, including variations in the prosody of their utterances. Such behaviors, often emotion-related, call for appropriate responses, but today’s spoken dialog systems lack the ability to do this. Recent work has shown how to recognize user emotions from prosody and how to express system-side emotions with prosody, but demonstrations of how to c...

Abstract In the Photon Factory 2.5 GeV electron storage ring at KEK, the upgrade project of its straight sections is underway. In the project, we improve the beam-position monitors (BPMs) and the global orbit feedback system. New BPMs are designed and installed in the straight sections and the orbit stabilization system is improved. The effect RF phase modulation to the beam position fluctuatio...

Title of Document: LONGITUDINAL SPACE-CHARGE WAVES INDUCED BY ENERGY MODULATIONS Brian L. Beaudoin, Master of Science, 2008 Directed By: Professor Patrick G. O’Shea and Professor Rami A. Kishek Department of Electrical and Computer Engineering High intensity beams that are space-charge dominated are important for applications such as free electron lasers that require high intensity and low emit...

The turn-by-turn directions provided in existing navigation applications are exclusively derived from underlying road network topology information, i.e., the connectivity of edges to each other. Therefore, the turn-by-turn directions are simplified as metric translation of physical world (e.g. distance/time to turn) to spoken language. Such translation that ignores human cognition of the geogra...
