Title: Network vulnerability analysis
Inventor: PRASANNA PIMPALNERKAR
IPC: H04L12/26
Filed: 2019-08-02
Abstract: A system for analysing distributed network vulnerabilities imports raw data from a current vulnerability scan associated with a network asset and determines a relationship between data aspects, then generates first and second nested relational data structures for the current scan and a previous scan, respectively, then merges these nested relational structures to provide contextual vulnerability data which can be categorised as ‘unchanged’ or ‘added’ and reported.

Inventor: HONGLING CHU
IPC: C10M107/10
Filed: 2019-12-09
Abstract: The present invention provides a low viscosity poly-α-olefin (PAO) lubricating oil and a synthesis method thereof. The method comprises the following steps: (1) dehydration treatment: the α-olefin raw material (e.g. 1-decene) is subjected to dehydration treatment so that the water content in the raw material is ≤10 ppm; (2) polymerization reaction: a reaction of the dehydration treated α-olefin raw material is carried out in the presence of a complex catalyst and gaseous BF3 to obtain a reaction product, wherein the pressure of the gaseous BF3 is 0.01 to 1 MPa; (3) catalyst removal: the reaction product obtained in step (2) is sequentially subjected to flash distillation, gas stripping, centrifugation, and washing treatment to obtain an intermediate product; (4) post-treatment: the intermediate product obtained in step (3) is subjected to distillation under reduced pressure to separate the unreacted α-olefin raw material and α-olefin dimers, and the remaining heavy fractions are subjected to hydrogenation saturation treatment followed by fractionation and cutting-off to obtain poly-α-olefin synthetic oils of different viscosity grades. The present invention has a simple process, with simple operation and mild process conditions, and the operating cost can be reduced.

Abstract: Identifying relations between items in transactions. Local conditional frequency pattern trees are generated in processing nodes in a computer system. The nodes in the local conditional frequency pattern trees represent items and a frequency of the items in the transactions. Global conditional frequency pattern trees are generated in the processing nodes. Each processing node in the processing nodes generates a global conditional frequency pattern tree using a set of local conditional frequency pattern trees in the processing node. The global conditional frequency pattern trees generated by the processing nodes are distributed such that each processing node in the processing nodes has the global conditional frequency pattern trees generated by other processing nodes. Patterns are generated by the computer system. A set of rules is generated using the patterns and the global conditional frequency pattern trees in the processing nodes, wherein the set of rules define the relations between the items.
