Management of cluster-wide resources with shared variables
The number of concurrent systems locks supported on a Sysplex is limited. Since persistent system locks may not be released for a long time, the limit may be reached resulting in outage periods. Access to resources may be managed through shared variables across a cluster of computing systems. Processes running on the cluster can use shared variables that are either exclusive or non-exclusive. An exclusive shared variable associates a resource with a process that has exclusive control of the resource. Since each exclusive shared variable is unique across the cluster, another application cannot create a second exclusive shared variable to control the resource. There is no limit on the number of exclusive shared variables that can be created on a cluster. Using exclusive shared variables instead of persistent system locks can prevent a system from reaching the limit of concurrent system locks while allowing processes exclusive use of resources. |

System for distributed media network and meta data server
A system and method of operation for a distributed media network and meta data server provides a low cost, efficient, reliable and versatile alternative to traditional media network systems. Multiple media data file servers are designated as primary or alternate data file servers for different media data media files. Related or linked media data files may be distributed throughout a media network which results in lower peak bandwidth usage at each media data file server. Each server in the distributed media network responds more quickly and efficiently due to its limited functionality and scope of media data files that it must server. Media data file servers transfer low bandwidth meta data to client devices allowing a significant increase in the number of clients which can simultaneously log in to a dedicated network server. The distributed system also provides media data owners with greater control over the media data files that they own by allowing the owners to encode, post or remove files from servers that they control and maintain. The alternate media data file servers of the distributed media network also can act as primary file servers during catastrophic errors of the primary media data file servers, thus resulting in a more reliable and fault tolerant media network. |

Method to indentify anomalous data using cascaded K-Means clustering and an ID3 decision tree
The invention is a computer implemented technique for id entifying anomalous data in a data set. The method uses cascaded k-Means clustering and the ID3 decision tree learning methods to characterize a training data set having data points with known characterization. The k-Means clustering method first partitions the training instances into k clusters using Euclidean distance similarity. On each training cluster, representing a density region of normal or anomaly instances, the invention builds an ID3 decision tree. The decision tree on each cluster refines the decision boundaries by learning the sub-groups within the cluster. A test data point is then subjected to the clustering and decision trees constructed form the training instances. To obtain a final decision on classification, the decisions of the k-Means and ID3 methods are combined using rules: (1) the Nearest-neighbor rule, and (2) the Nearest-consensus rule. |

Method and apparatus for speech coding
A method and apparatus for prediction in a speech-coding system is provided herein. The method of a 1st order long-term predictor (LTP) filter, using a sub-sample resolution delay, is extended to a multi-tap LTP filter, or, viewed from another vantage point, the conventional integer-sample resolution multi-tap LTP filter is extended to use sub-sample resolution delay. This novel formulation of a multi-tap LTP filter offers a number of advantages over the prior-art LTP filter configurations. Particularly, defining the lag with sub-sample resolution makes it possible to explicitly model the delay values that have a fractional component, within the limits of resolution of the over-sampling factor used by the interpolation filter. The coefficients of such a multi-tap LTP filter are thus largely freed from modeling the effect of delays that have a fractional component. Consequently their main function is to maximize the prediction gain of the LTP filter via modeling the degree of periodicity that is present and by imposing spectral shaping. |

To improve the transmission of data having different priorities in the switchable data network, telegrams are assigned priorities, with said telegrams (70-77) in each case having a beginning and an end. Data telegrams assigned a first priority are sent during a first phase from first users to second users, with the first phase being characterized by a defined receive time of the end of one or more of the data telegram at one or more second users. |
