Abstract: The invention relates to a method and system that provide a high performance and extremely scalable triple store within the Resource Description Framework (or alternative data models), with optimized query execution. An embodiment of the invention provides a data storage and analysis system to support scalable monitoring and analysis of business processes along multiple configurable perspectives and levels of granularity. This embodiment analyses data from processes that have been already executed and from ongoing processes, as a continuous flow of information. This embodiment provides defining and monitoring processes based on no initial domain knowledge about the process and such that the process will be built only from the incoming flow of information. Another embodiment of the invention provides a grid infrastructure that allows storage of data across many grid nodes and distribution of the workload, avoiding the bottleneck represented by constantly querying a database.

Abstract: An apparatus and operating method for generating a second one or more sequences of elements after receiving a first one or more sequence of elements. The apparatus includes an identifying device that receives a first one or more sequence of elements, accesses stored sequences, and identifies which of the stored sequences each of the first one or more received sequences of elements most closely resembles. The identifying device is operable to output for each received sequence of elements, an identifying signal indicative of the correspondingly identified stored sequence. The apparatus further includes a sequence generator that generates sequences of elements, operates to receive an input, an identifying signal, and generates a sequence of elements in response thereto.

Abstract: A data access system includes proxy servers for caching “local” copies of selected data sets stored on data servers to which users request access. Each proxy server is adapted to generate a subscription request message in respect of each identified cached data set for submission to a conventional “publish & subscribe” data distribution system. The data distribution system is arranged with access to “published” updates to data sets, made available from respective data servers. Upon receipt of a published updated data set having an identifier matching that in an earlier-received subscription request, the data distribution system forwards the data set to the subscribing proxy server to enable update to the respective cached copy. Thus, a proxy server, having decided to cache a particular data set, need only issue a subscription request message in order to receive all subsequent updates, as they become available, until choosing to remove the data set from the cache.

Abstract: A call distribution system, suitable for use in a network supporting a telemarketing call center, maintains call counts at a global data server and at a number of transaction servers which are connected in common to the global data server. A choice is made of either the global count or the local count to be used in addressing a distribution map which determines the destination for a particular call. The distribution map may be a minimum error map which minimizes the deviation from a planned distribution ratio wherever a call sequence is terminated.

Abstract: A decoder for speech signals receives magnitude spectral information for synthesis of a time-varying signal. From the magnitude spectral information, phase spectrum information is computed corresponding to a minimum phase filter which has a magnitude spectrum corresponding to the magnitude spectral information. From the magnitude spectral information and the phase spectral information, a time-varying signal is generated. The phase spectrum of the signal is modified by phase adjustment.

Abstract: A management system provides a remote access service to units of equipment at distributed locations of a communications network. For instance, it can provide automatic meter reading over a PSTN for utility companies. The management system initiates calls over the network to selected units, usually pre-determined, in response to call requests, and can provide considerable functionality such as authentication and batch processing of the request. Conflict with ordinary traffic on the network can be avoided by monitoring for ordinary traffic calls and clearing down any existing conflicting remote access calls or blocking any requested potentially conflicting remote access calls. Uncompleted or blocked remote access calls are automatically re-scheduled by the management system.

Abstract: Adaptive bit allocation to the channels of a sub/band coder (or to the coefficients of a transform coder) by using a fixed set of numbers of bits, only the selection of those channels to which the available bits are assigned being varied.
