At iGrid 2005 we demonstrated the transparent operation of a biology experiment on a test-bed of globally distributed visualization, storage, computational, and network resources. These resources were bundled into a unified platform by utilizing dynamic lambda allocation, high band-width protocols for optical networks, a Distributed Virtual Computer (DVC)(More)
The Petaflow project aims to contribute to the use of high performance computational resources to the benefit of society. To this goal the emergence of adequate information and communication technologies with respect to high performance computing-networking-visualisation and their mutual awareness is required. The developed technology and algorithms will be(More)
This paper discusses vision and challenges toward realization of {\em peta-flow computing}, which enables peta-scale information processing and communication. A promising application for peta-flow computing, a large-scale upper airway flow simulation and visualization over a long-fat network, is discussed with its requirements on peta-flow computing. Also,(More)
The hybrid applications are needed in dental research because the result of their operation could be predicted by both modeling of an oral truct and more than two kind of physical simulations. However, it takes long time to perform the hybrid applications, cost a lot of money and needs some experience to deal with them. This paper proposes a new execution(More)
This paper presents a new method for evaluating tooth brushing performance using audio collected from a smartphone. To do this, we use hidden Markov models (HMMs) to recognize audio data that include various types of tooth brushing actions, such as <i>brushing the outer surface of the front teeth</i> and <i>brushing the inner surface of the back teeth</i>.(More)
The Cybermedia Center, Osaka University (CMC) is a research institution that offers resource with knowledge and technology of all advanced research in the area of large-scale computation, information and communication, multimedia content and education. Currently, CMC involves in Japanese national grid projects such as JGN II (Japan Gigabit Network) and(More)
Computer simulations need a large amount of computational resources. We've believed that tightly-coupled computer is the first choice to perform the large scale simulations. This approach developing supercomputers never allows users to execute the interactive simulations so far. Here, a real time simulation indicates an interactive or streaming(More)
The effects of tongue position on sound properties were investigated by using simplified models of sibilant fricatives /s/ and /ʃ/. These were constructed from medical images of a native Japanese-speaking subject who pronounced both fricative sounds. The sounds generated by the models were experimentally measured and compared with the subjects /s/ and /ʃ/.(More)
