Abstract: PURPOSE: To judge whether earthquake data frame discrepancy is within an allowance range or not by selecting the width of an image as symmetry axis, dividing data around the symmetry axis, making the first and second data sets and comparing the data sets with a preset collating reference. CONSTITUTION: The results of earthquake testing groups are stored in an outside memory 210, prepared and modified to predict the image of earthquake data with specific symmetry around the axis. After they are modified, a device 200 is activated to read one frame of the earthquake data from a device 210 into an inside memory 220. An axis detector 240 accesses to the earthquake data and selects the axis as a symmetry axis. The maximum strength position is judged by a peak detecting technique. The earthquake data frame is sent to an edge detector 250 and a data point showing discontinuity in the data is identified, stored in an edge list and sent to a dividing means 260. The second edge list and the first edge list are collated by a collating device 160.

Abstract: PROBLEM TO BE SOLVED: To reduce the delay of data access by processing data retrieving operation, which does not require performing of a first prescribed task, without performing the first prescribed task. SOLUTION: A queue manager 48 fetches a first job from the head of a list to decide whether making a watermark is required or not, etc., (S350). When a request does not require a watermark, the job is added to the job queue of a user within 'fast ring' whose processing operation to be performed is relatively faster than the making of the watermark (S410). When the making of a water mark is required, its processing job is added to the queue of a user in circularly linked 'slow ring' circularly linking jobs requiring the making of the watermark (S380). Consequently, this helps the improvement of assignment of resources to reduce delay to be encountered in the case of operation which is not processor intensive.

Abstract: A data processing apparatus has: a memory unit 402; a system software unit 401 including a plurality of parsers 401A, 401B, for implementing a Document Object Mode (DOM) application programming interface, including a unit for receiving documents from an originating application 11, 21 and a unit for processing received documents using one of the parsers in order to convert each received document into an object model; and a system software unit for storing each object model into the memory unit; where the unit for processing sends a received document to a particular one of the plurality of parsers depending on the format of the received document. This allows the DOM to accept documents in formats other than XML/HTML, e.g in COBOL.

Abstract: Provided are a system and a method for data retrieval which identify from requested data retrieval operations those operations which require a particular processing task to be performed, and then separate those operations from operations not requiring the processing task. The separated sets of tasks are queued separately for independent processing. This enables resource scheduling to be performed which avoids the operations which do not require performance of the task from having to wait for the operations which do require the task. This is an advantage where the task is a processor-intensive task such as digital watermarking of images. A particular resource allocation method includes enqueing the set of operations requiring the processing task in a circularly linked list and then employing a scheduler to implement a round-robin allocation of resources for each of the system users in turn. Also provided is a pre-fetch policy whereby sets of data objects are retrieved from a data repository for processing in response to data retrieval requests and post-retrieval processing such as watermarking is initiated before an individual data object in the set has been selected.

Abstract: The present invention relates to the detection of errors in seismic data and in particular to apparatus for detecting errors in frames of seismic data that can be presented as images. Due to the techniques used for collecting seismic data, an image produced to represent that data will typically be expected to exhibit an inherent symmetry about an axis. The apparatus of the present invention comprises a storage device for storing a frame of seismic data which can be presented as an image, a selection device for selecting an axis within the image as the axis of symmetry, and a divider for dividing the data about the axis of symmetry to create first and second sets of data. Further it includes a comparison means for comparing the sets of data according to preselected matching criteria to determine, based on the degree of matching, whether the extent of mismatch in the frame of data is within a predetermined tolerance.

Abstract: A tool 30 for graphically defining an expression, such as an SQL expression, comprises a graphical user interface (GUI) 31 with means, responsive to user input, for defining one or more tree structures comprising a hierarchical series of nodes, and one or more lists, each list item being associated with a respective node of an associated tree, and an expression generator 32 which analyses the graphical definition to generate an expression based on the structure of the tree and any list items associated with the tree. The tool may be used to configure a message broker or a database query. Two or more tree structures may be defined, where nodes are associated by a list item, and the expression generator joins the tree structures on these nodes. An input tree structure may have two or more associated lists, from which the generator generates a logical OR expression. The user may also define output tree structures.

Abstract: Provided is a message broker 30 and a method of processing message content within a publish/subscribe message distribution service. The message broker and method extends publish/subscribe service capability to heterogeneous, pervasive communications networks in which different subscriber systems 20 can have very different capabilities in terms of their multimedia presentation capabilities, processing capabilities and storage capabilities. The broker 30 modifies the content of messages received from publisher application programs 10 to conform to the subscriber system capabilities prior to sending derived messages to the subscriber applications 20. There may be a distributed collection of brokers which communicate with each other, instead of a single broker. Subscribers register their capabilities with the broker when requesting information on subjects of interest.

Abstract: A tool (30) for graphically defining an expression is disclosed. The tool comprises a graphic user interface (GUI) component (31) and an expression generator component (32) adapted to read a graphic definition of an expression provided by a user through the GUI component. The GUI component is responsive to user input to define one or more tree structures comprising a hierarchical series of nodes, and one or more lists comprising a plurality of items, each list item being associated with respective node of an associated tree. The expression generator component analyzes the graphic definition and generates an expression based on the structure of the or each tree and any list items associated with respective nodes of a tree.
