Abstract: In some implementations, an event data analysis system may identify event data that indicates user interactions with an application, each of the user interactions corresponding to an interaction with data filters. The system may generate specificity scores, each of the specificity scores indicating, for a corresponding user interaction, a measure of specificity associated with data filters that correspond to the corresponding user interaction. The system may filter the event data stream based on the specificity scores. The system may generate at least one entropy value for at least one data filter, each entropy value indicating a rate of change of a corresponding data filter. The system may identify, based on the specificity scores and the at least one entropy value, a set of relevant filter values associated with the event data. The system may provide output indicating the set of relevant filter values.

Abstract: A system may include a gas inlet configured to receive a gas stream comprising hydrogen sulfide (H2S), a first particle bed comprising a plurality of first particles, the first particles comprising a support material and a first metal material comprising at least one of: iron (Fe), nickel (Ni), chromium (Cr), cobalt (Co), vanadium (V), copper (Cu), and cerium (Ce); and the first particle bed in fluid communication with the gas inlet. A system may include a second particle bed comprising a plurality of second particles comprising a support material and a second metal material comprising at least one of: iron (Fe), chromium (Cr), nickel (Ni), and vanadium (V), the second particle bed being in fluid communication with the first particle bed. A system may include a gas outlet in fluid communication with the second particle bed, the gas outlet being configured to provide an output stream comprising hydrogen (H2) gas.

Abstract: Anion-exchange membranes are useful for electro-membrane processes such as electrodialysis (water desalination, separation of inorganics from organic molecules, separation of specific inorganic ion, etc.), in-situ ion-exchange and ion substitution, electro-deionization for producing ultrapure water, polymer electrolyte membrane for alkaline fuel cell and electrolysis applications. The present invention discloses an acid and base resistant fluorinated hydrocarbon based anion-exchange membrane and its method of preparation thereof. In the first step co-polymerization is carried out between N-isopropylacrylamide and 1-vinylimidazole. In the second step, obtained inter-polymer of isopropylacrylamide-co-vinylimidazole co-polymer is mixed with poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) (IA-co-VI/PVDF-co-HFP), which is used for casting membrane film of desired thickness. The obtained casted membrane thin film is quaternized in methyl iodide solution.
