Abstract: Re-distribution servers are installed at the branch points of a network for distributing streaming data, and route costs between two re-distribution servers are collected. Then, a distribution route tree from a source to a plurality of clients is automatically generated based on the cost information.

Abstract: In the analysis of one-dimensional sequences of molecules, the longest common subsequence, the number of elements constituting the subsequence, and appearance positions of the subsequence are determined by a novel and simple method, and processes, such as homology decision, homology search, motif search and alignment are performed based on the results. In the analysis of these-dimensional structures of molecules, limiting conditions, such as geometrical arrangements of elements, are introduced to realize the determination of correspondence of three-dimensional structures at high speeds, and whereby it is made possible to achieve such processing as superposed display of three-dimensional structure of molecules, retrieval of three-dimensional structure, and evaluation of functions. Moreover, the molecules are divided into secondary structure that are then related to each other based on spatial similarity among the secondary structures.

Abstract: The e-mail system includes: a text information notifying unit (21) for notifying a second information terminal (40) of text information of an e-mail message; a sound information storing unit for storing sound information related to the e-mail message; and a managing unit for managing association between the e-mail message and its related sound data. With this feature, it is possible for a user to reply to an original e-mail message by voice, thereby freeing a user from troublesome inputting text reply. Further, upon receipt of such a voice reply, the sender of the original mail can manage the reply in association with the original mail. Furthermore, upon receipt of an e-mail massage having information about sound information added thereto, it is possible to smoothly obtain the sound information.

Abstract: The invention provides an apparatus for extracting a common structure from two three-dimensional structures each formed from a set of sequenced points. The apparatus is constructed so as to extract one of common portions with which the common portion length of the two point sets superposed with each other exhibits a greatest length and the cumulative sum of distances between matched points of the two point sets superposed with each other exhibits a lowest value as an optimum common structure. The common structure extraction apparatus is suitably used to analyze a molecular structure to make clear a mechanism for manifestation of a function of a substance in order to investigate a property of a novel substance such as a protein or artificially produce a novel substance in the fields of physics, chemistry and so forth.
