    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: Provided are transaction processing systems and methods enabling interoperation between data processing resources which implement different transaction processing models. The systems and methods also enable resources which were not created using object oriented programming techniques to interoperate with object oriented programs and to utilise object orientation concepts. The systems and methods allow transactions to be controlled using consistent operations across multiple object oriented transaction services. A set of object classes is implemented on a transaction processing system, the object classes including: an object oriented wrapper (300) for an existing system interface; an interface implementation (310) which corresponds to a different transactional model from that of other system resources; and a transaction class (320) which maps transactional operations of one model to transactional operations of the second model, while taking account of transactional operations which are within transactional scope according to one model and outside transactional scope according to the second model.

    Abstract: In a publish/subscribe data processing broker network having a plurality of broker data processing apparatuses each of which has an input for receiving published messages directly from a publisher application and/or receiving subscription data from a subscriber application, a first broker data processing apparatus has: a unit for receiving a data message published on a first topic by a first publisher application; and a unit for forwarding the received published data message to a subscriber application which has requested, by entering subscription data, to receive a message on the first topic; wherein the first broker data processing apparatus sends a declaration to at least one other broker data processing apparatus of said plurality of broker data processing apparatuses declaring that the first broker data processing apparatus is the only broker data processing apparatus that is directly communicating with a publisher application that is publishing on the first topic.
