  • Publication number: 20220164405
    Abstract: A machine learning model generates predicted performances of multiple entities at a future time based on corresponding ex post data associated with each of the multiple entities and corresponding entity profiles associated with each of the multiple entities. One or more items of content to be provided to one or more of the multiple entities are selected based on the predicted performances of the plurality of entities. An indication of the one or more items of content that are to be provided to the one or more of the multiple entities is transmitted to a third-party system.

  • Patent number: 6784143
    Abstract: The use, in a minor amount, of a detergent composition comprising one or more metal detergents which comprises metal salts of organic acids, wherein the detergent composition comprises more than 50 mole %, based on the moles of the metal salts of organic acids in the detergent composition, of: (I) a metal salt of an aromatic carboxylic acid, or (II) a metal salt of a phenol, or (III) both a metal salt of an aromatic carboxylic acid and a metal salt of a phenol, in a lubricating oil composition for improving the oxidation resistance of the lubricating oil composition, wherein the amount of phosphorus and sulfur in the oil composition is less than 0.09 mass % and at most 0.5 mass % respectively, based on the mass of the oil composition. It has also been found that a detergent composition comprising more than 50 mole % of a metal salt of an aromatic carboxylic acid improves the reduction in wear in an engine.
