Abstract: A fault cause estimating system includes: an initial model generating section which creates an initial fault derivation model indicating a derivation among faults and an initial event derivation model indicating a derivation among the faults and events, based on a basic model definition; an extended Baum-Welch calculating section which creates a fault derivation model which is a transition of a combination of device classes and faults and an event derivation model which is a transition of a combination of device classes and events, based on a instance definition, a class definition, the initial fault derivation model, the initial event derivation model and an event sequence for learning; an instance derivation probability calculating section which creates an instance deviation model of a derivation of an occurrence device based on the event sequence for learning; and an extended Viterbi calculating section which estimates an event cause fault based on the instance definition, the fault occurrence location cla

Abstract: A system of reserving a connecting service to the internet at a time period, includes a reservation table and a contract unit. A state with regard to a reservation for a connecting service to the internet at a time period is stored in the reservation table. The contract unit inputs a reserving demand to reserve the connecting service to the internet at a certain time period from a user to judge whether the reserving demand is permitted with reference to the reservation table.

Abstract: A syntax coverage percentage measuring system includes a BNF rule check table which has BNF data respectively corresponding to BNF syntax rules. A first file reading section reads each of test input files and carries out lexical analysis to data of each of the read test input files to classify into tokens. A first syntax analyzing section carries out syntax analysis to each of the tokens, and marks one of the BNF data of the BNF rule check table corresponding to the token. A coverage percentage output section acquires a total number of the BNF data and a number of the marked BNF data from the BNF rule check table, and calculates a coverage percentage based on the total number of the BNF (data and the number of the marked BNF data. An output section outputs the coverage percentage calculated by the coverage percentage output section.

Abstract: A node (500) transmits a message to a reception node (501) via a message router (600). In the message router (600), a DB (database) read unit (240) extracts, as reception target candidate nodes, nodes in a sub-tree rooting in a domain designated by a domain path that is an attribute value representative of a message receiver. A policy engine (610) applies a policy, which has been imparted to a reception target node, to the header of the message, and selects the reception node. In this way, an appropriate node is selected in accordance with the characteristics of a message, thereby realizing linkage between nodes, such as introduction of front processing service nodes.

Abstract: A conference assisting system includes a plurality of conference room servers each disposed for one of conference rooms, and a network including a plurality of VLANs each disposed for one of departments to which participants belong. A user having a mobile terminal connected to a VLAN specifies another mobile terminal to share conference files with the another mobile terminal. The user uses the conference server to project a file in the own mobile terminal for presentation by using an image projector through the conference sever.

Abstract: A policy processing system includes a storage section for storing a plurality of policies and a policy transition processor. Each of policies includes policy transition information including at least one transition-destination policy for a corresponding policy. Policy transition is performed such that, when a policy is activated due to occurrence of an event that matches the policy, the policy activated is changed to a corresponding transition-destination policy according to the policy transition information of the policy activated.

Abstract: A system of reserving a connecting service to the internet at a time period, includes a reservation table and a contract unit. A state with regard to a reservation for a connecting service to the internet at a time period is stored in the reservation table. The contract unit inputs a reserving demand to reserve the connecting service to the internet at a certain time period from a user to judge whether the reserving demand is permitted with reference to the reservation table.

Abstract: A GDMO translator is provided, which is capable of generating output files with various syntaxes from an input file with the same syntax, and which is capable of describing different outputs containing, for example, an indefinite number of nesting structures.A parser 140 reads an input file and produces an abstract syntax tree by conducting an analysis according to a prescribed syntax. The abstract syntax tree is then stored in the abstract syntax tree data base 120 through the data base access means 130. The translation means 80 reads the output template 100 through the syntax reading means 60 and the lexical analysis means 70.

Abstract: When a data manipulation language execution unit (120) executes a data manipulation routine, an object manipulation unit (150) requests a database access unit (170) to make the database access unit retrieve an object in order to obtain the object from a database (180). The object manipulation unit registers the object in an object descriptor table (160) and supplies the object to the data manipulation language execution unit. The data manipulation language execution unit accesses the object in accordance with an object descriptor and an attribute name. The object manipulation unit fetches the object designated with the descriptor from the object descriptor table. The object manipulation unit supplies object to an attribute extraction unit (140). The attribute extraction unit fetches an attribute in accordance with the object.
