摘要： A filter media and methods are provided. The media is stretchable and exhibits a high degree of elongation which thereby extends its surface area during pleating. By extending surface area of media during pleating, the initial differential pressure is lowered as the area of media is stretched while keeping the same efficiency range with a compressed thickness of media on the affected area.

摘要： A system and method are presented that identify new, modified, unchanged, and deleted files in an incremental backup through a file list maintained on the backup destination. The FileList is a flat file in which file information about each file on a source node is stored sequentially into the file. During a subsequent incremental backup, the FileList is read sequentially from the backup destination and is used to generate a search tree. A hash value based on the file path is the key to the search tree, with the file's modified time and size being hashed together to form the value of the tree's key-value pair. Files are examined on the source and compared to the key-value pairs in the search tree. Status information in the search tree is modified to indicate discovered files. Unmodified status information identifies files that have been deleted since the previous backup.

摘要： Embodiments generally relate to systems and methods for detecting topics in social media data. More particularly, the systems and methods can extract a concept hierarchy from a set of data, wherein the concept hierarchy comprises a plurality of layers. Further, the systems and methods can train topic models based on the content in each of the layers. Still further, the systems and methods can select the most appropriate topic model for social media data by balancing the complexity of the model and the accuracy of the topic detection result. Moreover, the systems and methods can use the most appropriate topic model to detect topics in social media data.
