A single bunch of charged particles in a storage ring is a system of 10-10 coupled non-linear oscillators with radiative energy loss and compensated by the accelerating cavity. A stable collective mode in such system was induced and observed in the SPEAR storage ring using a turn-by-turn phase space monitor. New possibilities of using this mode as a tool to experimentally study non-linear dynam...

Humans adapt the instructions provided in route directions to the assumed spatial knowledge of the receivers; the majority of route directions is provided to wayfinders with at least partial spatial knowledge of the environment. However, today’s navigation systems assume no a-priori knowledge. Most of current research addresses this by exploring means to personalize assistance through the captu...

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...
