  • Publication number: 20190188156
    Abstract: Implementations described herein provide a storage system including a cache, such as a solid-state cache or other relatively higher speed memory cache, and a disc array or relatively higher capacity mass data store. As the storage system receives write requests from a host device, the data of the write requests is initially written to the cache. Eventually, such data is committed to the mass data store in a flushing process. A flushing manager selects data blocks from the cache to flush to the mass data store. The flushing manager selects a sequence of data blocks that are contiguously stored on the mass data store such as to increase performance for I/O operations in the mass data store. The flushing manager utilizes a data structure, such as a binary search tree, to identify the contiguous data blocks to flush.

  • Patent number: 10301446
    Abstract: A method for generating a microstructure that includes microcellular bubbles, in a material that includes molecules of a thermoplastic polymer, comprises: determining a size-index for the material that represents an average size of the thermoplastic polymer molecules included in the material, and in response to the determined size-index, setting a parameter of a process to generate a microstructure in the material that includes microcellular bubbles. The process to generate a microstructure in the material includes: 1) infusing into the material, during a first period, a gas that does not react with the material, 2) making the gas-infused material thermodynamically unstable.

  • Patent number: 10306459
    Abstract: A method includes maintaining a VLR validation database accessible by an SS7 STP and receiving, by the STP, a MAP SAI request message. The method also includes determining that the MAP SAI request message includes a VLR identifier not recorded in the VLR validation database accessible by the STP and recording the VLR identifier in the VLR validation database. The method further includes receiving a first MAP LU request message and detecting a VLR identifier in the first MAP LU request message and determining that the VLR identifier read from the first MAP LU request message does not match the VLR identifier recorded for a subscriber in the VLR validation database. In response to determining that the VLR identifier does not match the VLR identifier recorded for the subscriber in the VLR validation database, the first MAP LU request message is rejected.

  • Publication number: 20190044932
    Abstract: A method for authenticating a mobility management entity (MME) for outbound roaming subscribers includes maintaining a Diameter authentication information request (AIR)/update location request (ULR) mapping database at a Diameter edge agent (DEA). A Diameter AIR message is received at the DEA. The DEA determines that the AIR message includes a visited public land mobile network identifier (VPLMN ID) not of record in the database. The DEA records the VPLMN ID in the database. A Diameter ULR message is received at the DEA, and a VPLMN ID is read from the ULR message. The DEA determines that the VPLMN ID read from the ULR message does not match the VPLMN ID recorded for the subscriber in the database. In response to determining that the VPLMN ID does not match the VPLMN ID recorded for the subscriber in the database, the DEA rejects the ULR message.

  • Publication number: 20170200041
    Abstract: A system includes an aerial image database containing sensor data representing an aerial image of the earth surface, the sensor data comprising a feature vector for each pixel in the aerial image. A processor applies a plurality of classifiers to each feature vector to produce a plurality of classifier scores for each feature vector. The processor then determines a plurality of cluster probabilities for each feature vector, each cluster probability for a feature vector indicating a probability of the feature vector given a respective cluster of feature vectors. The processor uses the cluster probabilities for the feature vectors to form a respective weight for each of the plurality of classifiers. The processor combines the weights and the classifier scores to form an ensemble score for each pixel, the ensemble score indicating which of two possible land cover types is present on a portion of the earth surface represented by the pixel.
