Abstract: Example techniques may include: receiving information from a content provider; generating a bidding strategy based on the information, where the bidding strategy indicates a percentage of first content to be presented at a specified location on a computing device display; generating an initial bid for the one or more criteria associated with the first content in a content auction based on performance of second content that has one or more attributes in common with the first content, where the initial bid includes a monetary amount to pay in the content auction for an action relating to the first content; determining performance metrics for the one or more criteria and the initial bid based on results of the content auction; and automatically determining a revised bid for the one or more criteria based on the performance metrics and the bidding strategy.

Abstract: In a computer-implemented method of determining an abstraction of a plurality of differentiated goods available for exchange, data regarding each differentiated good is stored in a computer storage, wherein the data regarding each differentiated good includes an attribute value assigned to at least one attribute of the differentiated good. A processor of a computer determines a first abstraction of the plurality of differentiated goods based on the stored data. The first abstraction includes at least one abstract good. Each abstract good includes one or more differentiated goods. At least one abstract good of the first abstraction includes at least two distinct differentiated goods. The processor determines for each abstract good a specification for the abstract good based on the data regarding one or more differentiated goods forming the abstract good. The processor stores in the computer storage the specification determined for each abstract good.

Abstract: A method for separating the alkaline ore and spent carbon fractions contained in spent electrolytic cell cathode comprising the steps of:(a) grinding the spent cathode to a suitable particle size;(b) treating the product of step (a) with ultrasonic energy, sulfuric acid, or both, for a period sufficient to achieve a measurable particle size distinction between the alkaline ore and carbon particles; and(c) screening the alkaline ore and carbon particles to achieve separation of the alkaline ore particles which pass through the screen from the carbon particles which are retained on the screen.
