Abstract: Disclosed is a method for testing and evaluating a short-circuit withstand capability of a press-pack power component.

Abstract: A welding bead modeling method for wire-arc additive manufacturing, a device therefor and a system therefor including using a dynamic parameter method, and using different welding process parameters in the same welding bead in the a wire-arc additive manufacturing process to obtain a welding bead with synchronous and dynamic changes in profile along with the dynamic changes of the welding process parameters. The method further comprising using a line laser sensor for scanning to obtain the segmented profile of the processed welding bead, and corresponding each welding bead profile to the welding process parameters one by one to train the neural network as training data, so as to obtain a welding bead modeling model capable of obtaining the corresponding welding bead profile according to the input welding process parameters.

Abstract: A method is used in managing data accesses in storage systems. An access path to a storage object is evaluated. The storage object is associated with a first storage processor of a storage system for providing access to the storage object. The storage object is accessed using a second storage processor of the storage system. The storage system includes source and destination storage pools configured such that performance characteristics associated with the source storage pool is different from performance characteristics associated with the destination storage pool. The storage object resides in the source storage pool associated with the first storage processor. Based on the evaluation, the access path of the storage object is changed to the second storage processor based on a policy. The policy determines available storage space in the destination storage pool associated with the second storage processor for migrating the storage object to the destination storage pool.

Abstract: Disclosed herein are various embodiments that include a method and a passive optical network (PON) for supporting a mobile network. In various embodiments, a baseband unit (BBU) is configured to measure an optical path delay from each remote radio unit (RRU) of a plurality of RRUs to the BBU during an initialization phase. The BBU synchronizes all the RRUs in the mobile system by adjusting the timing of each path based on the optical path delay between each RRU and the BBU. The BBU determines a mapping rule that maps each resource block assigned to each RRU of the plurality of RRUs to a different PON transport block. The BBU transmits the mapping rule to each RRU of the plurality of RRUs. In certain embodiments, the mapping rule may be recalculated dynamically after the initialization phase.

Abstract: A method is used in iterating in parallel for deduplication. Based on an iteration scheme, a collection of sections is selected from a set of storage extents. Each section of the collection of sections includes subset of the contents of a storage extent of the set of storage extents. Based on the iteration scheme, each section of the collection of sections is arranged in an ordered arrangement. Based on the ordered arrangement, a deduplicating technique is applied in parallel to each section of the collection of sections.

Abstract: Methods and apparatus for organizing a plurality of versions of a file in a file system. The plurality of versions of the file are stored in a data structure having a hierarchical organization that reflects relationships among the plurality of versions. Each version of the plurality of versions is assigned a name that identifies its position in the hierarchical organization. The hierarchical organization of the data structure and the descriptive naming convention used for the plurality of versions in the data structure facilitates deleting a version while retaining other versions derived from the version following the deletion of the version, and enables a staged initialization of the data structure upon system start-up.
