    In this paper, we propose a round-robin burst assembly and constant burst transmission for optical burst switching (OBS) network. In the proposed method, ingress edge node has multiple buffers where IP packets are stored ...
  • Oh, Seiwoong; Kado, Daisuke; Taira, Tomohiro; Fujikawa, Kazutoshi; Shimojo, Shinji; Arikawa, Masatoshi; Miyahara, Hideo (Nara Institute of Science and Technology奈良先端科学技術大学院大学, 1997-06)
    Currently, most of networked virtual reality systems do not consider the scalability of the system in terms of the network. They assume high speed network among rather small number of distributed users. However, as high ...
  • Amemori, Kenichi; Ishii, Shin (Nara Institute of Science and Technology奈良先端科学技術大学院大学, 1998-04)
    In this article, we report a simulation result of unsupervised learning characterized as temporally and spatially local. After the learning, the network preserves an input sequence whose intervals vary in sub-millisecond ...
  • Ohtake, Satoshi; Inoue, Tomoo; Fujiwara, Hideo (Nara Institute of Science and Technology奈良先端科学技術大学院大学, 1997-07)
    The test generation problem for a sequential circuit capable of generating tests with combinational test generation complexity can be reduced to that for the combinalional circuit formed by replacing each FF in the sequenlial ...

    This paper compares the expressive power of five languagebased access control models. We show that the expressive powers are incomparable between any pair of history-based access control, regular stack inspection and shallow ...
  • Sakurai, Yasushi; Yoshikawa, Masatoshi; Kataoka, Ryoji; Uemura, Shunsuke (Nara Institute of Science and Technology奈良先端科学技術大学院大学, 2002-05)
    Similarity retrieval mechanisms should utilize generalized quadratic form distance functions as well as the Euclidean distance function since ellipsoid queries parameters may vary with the user and situation. In this paper, ...
