  • Publication number: 20190034464
    Abstract: The current document is directed to methods and systems that collect data within computing facilities according to data-collection specifications contained in data-collection manifests and that export a specified portion of the collected data to remote data-processing and data-analysis systems based on data-export specifications encoded within data-export whitelists. In a disclosed implementation, collected data is hierarchically encoded within a file or document that is efficiently processed, using one or more regular expressions that comprise a data-export whitelist, to extract the specified portion of the collected data for export to a remote data-processing and data-analysis system.

  • Patent number: 8580897
    Abstract: Disclosed herein is a crosslinked fluoropolymer network formed by the free radical initiated crosslinking of a diacrylate fluoropolymer. The diacrylate copolymer is of formula CH2?CR?COO—(CH2)n—R—(CH2)n—OOCR??CH2, wherein R is selected from the group consisting of i) an oligomer comprising copolymerized units of vinylidene fluoride and perfluoro(methyl vinyl ether), ii) an oligomer comprising copolymerized units of vinylidene fluoride and hexafluoropropylene, iii) an oligomer comprising copolymerized units of tetrafluoroethylene and perfluoro(methyl vinyl ether), and iv) an oligomer comprising copolymerized units of tetrafluoroethylene and a hydrocarbon olefin, R? is H or —CH3, n is 1-4 and wherein said oligomer has a number average molecular weight of 1000 to 25,000 daltons. The source of the free radicals may be a photoinitiator or an organic peroxide.

  • Patent number: 8170941
    Abstract: A system and computer-implemented method for generating random vectors for estimating portfolio risk is provided. Historical financial variable data of financial assets is stored in a memory. Parameters of a copula are estimated. Random vectors are generated from the copula. Risk for the financial assets is calculated based on the random vectors.
