Abstract: Memory is used, including by receiving at a processor an indication that a first piece of metadata associated with a set of backup data is required during a block based backup and/or restore. The processor is used to retrieve from a metadata store a set of metadata that includes the first piece of metadata and one or more additional pieces of metadata included in the metadata store in an adjacent location that is adjacent to a first location in which the first piece of metadata is stored in the metadata store, without first determining whether the one or more additional pieces of metadata are currently required. The retrieved set of metadata is stored in a cache.

Abstract: The present disclosure describes systems and methods for performing multi-level reservoir history matching. At least some illustrative embodiments include a method that includes generating a first history-matched model using at least one updated model parameter derived from one or more existing model parameters, generating a set of second history-matched models by applying a probabilistic inversion to the first history-matched model, and deriving a set of third history-matched models from the set of second history-matched models. The method further includes generating dynamic simulation realization sets using each of the set of third history-matched models, ranking each of the set of third history-matched models based at least in part on the dynamic simulation realization sets, and presenting a production forecast to a user based on the highest ranked third history-matched models.

Abstract: An apparatus for premixing fuel and air prior to combustion in a gas turbine engine includes an annular fuel passage receiving fuel from a fuel source. The annular fuel passage includes a fuel plenum and has a wave shape with a peak section surrounded by trough sections. An annular air passage surrounds the annular fuel passage. The annular air passage receives air to be mixed with the fuel in the fuel passage for downstream combustion. A plurality of swirler vanes are disposed in the annular air passage adjacent the fuel plenum.

Abstract: A combustion system is provided having a liner, a flow sleeve, a flow-obstructing element, and a venturi. The liner is disposed around a combustion region. The flow sleeve is disposed around the liner. The liner and the flow sleeve cooperate to create an air passage having an airflow located between the liner and the flow sleeve. The flow-obstructing element is disposed within the air passage, and generally obstructs the airflow in the air passage to create wakes in the airflow. The venturi is disposed downstream from the flow-obstructing element, and generally restricts and diffuses the airflow in the air passage to reduce wakes in the airflow.

Abstract: A system includes a fuel nozzle. The fuel nozzle includes a hub, a shroud disposed about the hub, an airflow path between the hub and the shroud, multiple first fuel outlets disposed on the hub, and multiple swirl vanes disposed in the airflow path downstream from the multiple first fuel outlets.

Abstract: In an embodiment, a system includes a turbine fuel nozzle having a hub with an axis, a shroud surrounding the hub along the axis, an air flow path between the hub and the shroud, and a fuel flow path. The turbine fuel nozzle also includes a swirl vane extending between the hub and the shroud in a radial direction relative to the axis. The swirl vane includes a fuel inlet coupled to the fuel flow path, a fuel chamber extending from the fuel inlet, and a plurality of fuel outlets extending from the fuel chamber to the air flow path. The plurality of fuel outlets is positioned at an axial distance of at least approximately ? of an axial length of the fuel chamber downstream from an upstream point along an upstream edge of the fuel chamber.

Abstract: Information management is disclosed. A file output from an application to an operating system is intercepted before the file output arrives at the operating system. The file output is directed towards protected data. The intercepted file output is analyzed to determine whether a predetermined type of version of the protected data has been created. In the event it is determined that the predetermined type of version of the protected data has been created at least in part because the analyzed intercepted file output includes a modification to the protected data, the protected data automatically backed up, including by storing at least a portion of the file output as a backup version of the protected data. In the event it is determined that the predetermined type of version of the protected data has not been created, the protected data is not backed up.

Abstract: Information is retrieved by receiving a list of one or more files to be restored; and obtaining a contiguous group of blocks that includes a first segment of one or more blocks associated with the one or more files to be restored, a gap of one or more blocks that are not associated with the one or more files to be restored that is adjacent to the first segment, and a second segment of one or more blocks associated with the one or more files to be restored that is adjacent to the gap.
