Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for receiving data including a user identifier associated with a user and one or more key-value pairs associated with the user's access of a resource. Each key-value pair includes a key and a value provided by the resource. Upon determining that the received data satisfies one or more rules associated with a user list comprising user identifiers, the user identifier is added to the user list.

Abstract: Systems and techniques are described for splitting user-lists. A described technique includes obtaining a master user-list, the master user-list including object identifiers that are respectively associated with web clients; obtaining a splitting factor that controls a splitting of the master user-list; creating a reduced user-list from the master user-list based on the splitting factor such that the reduced user-list maintains a statistical fidelity of the master user-list, the reduced user-list including fewer than all of the object identifiers included in the master user-list; and providing the reduced user-list.

Abstract: A method to determine a risk of failure for a machine including: generating a first value for a risk of failure of the machine, wherein the first value is determined by a first model receiving as an input a condition of the machine and the first model includes a relationship derived from historical machine failures and correlating the input condition of the machine to a value for the risk of failure; generating a second value of the risk of failure of the machine, wherein the second value is determined by a second model receiving as an input information regarding wear or degradation of the machine and the second model includes a relationship correlating the input information regarding wear or degradation to a value for the risk of failure, and determining a total risk of failure based on the first and second values of the risk of failure.

Abstract: A computer-implemented maintenance/repair workscope development tool uses one or more sources of gas turbine engine/fleet operational condition data, gas turbine engine/fleet historical data and gas turbine engine/fleet specific information, including other historical, statistical and maintenance/engineering records data to develop a recommended maintenance/repair workscope. A method, system and program product are described for producing a recommended maintenance/repair workscope for individual machines and/or machines on a fleet level. Relevant domain knowledge/information models along with appropriate application rules defining maintenance/repair requirements are predetermined and maintained in a network accessible database/repository. A rules/reasoner engine is used to develop logical inferences and make intelligent workscope choices based upon user input situational data, operational condition data stored in data/information databases and the predetermined knowledge/information models and rules.

Abstract: Techniques for epoch pipelining are disclosed. In one particular exemplary embodiment, the techniques may be realized as a method for epoch pipelining comprising the steps of beginning a first epoch, determining for one or more pages of memory if the pages of memory are likely to be modified in a subsequent epoch, performing a first operation on the pages of memory that are likely to be modified in a subsequent epoch, beginning a second epoch, subsequent to the first epoch, performing a second operation on the pages of memory that are not likely to be modified in a subsequent epoch, and ending the first epoch, wherein the first operation and the second operation are dissimilar.

Abstract: Systems, methods, and computer programs encoded on a computer-readable storage medium for allocating a minimum number of impressions to a content item in order to satisfy a delivery goal for the content item during a certain period of time are described. In some implementations, a satisfaction index (SI) for each content item can be used. The SI is a metric that reflects the degree to which a content selection service is on pace to meet a delivery goal for a content item within some period. The SI can be used to compare the number of impressions that have been allocated to the content item thus far in a period to the delivery or allocation goal for the content item in the period. A content selection service may determine scores for impression allocations based on both an estimate of value and the SI for a candidate content item in order to balance the goals of meeting delivery goals and optimizing impression inventory value.

Abstract: Competitive content item serving is provided. Competitive content item serving can include the ability to receive a request for a content item and to compare an expected return for a first network content item to an expected return for a second network content item. Based upon the comparison, it can be determined whether to provide the first network content item to the publisher.

The second data set includes a second set of data attributes associated with a second set of users. The method includes generating user cluster information based at least in part on at least one common data attribute associated with the first set of users and the second set of users. The method includes providing the user cluster information to a data purchaser.

Abstract: Among other disclosed subject matter, a computer-implemented method for managing data includes receiving user data from a data provider. The user data includes user information in a first format. The method includes transforming the user data in the first format to user data in a second format. The user data in the second format includes a subset of the user information and the second format is defined by a data subscriber. The method includes providing the user data in the second format to the data subscriber.

Abstract: Methods, systems, computer program products and techniques are described for presenting content. One method includes generating, by a data exchange engine executing on one or more processors, one or more user lists based on owned or permissioned data; importing, by the data exchange engine, user specific data from at least one of a browser, a third-party server, or an advertising database; generating, by the data exchange engine, one or more associations between one or more user lists and the imported user specific data, wherein the associations define whether user specific data correlates to one or more predefined definitions associated with a given user list; storing the associations; and providing user list identifying information to subscribers to a given user list in response to receipt of a content request from a user included in a respective user list.

Abstract: A computer-implemented method comprises identifying a user list where the user list includes a definition that characterizes members included in the user list, identifying available impressions that are satisfied by the definition, bundling the user list and the impressions into a bundle including determining a price to charge a consumer of the bundle, and providing the bundle to a consumer.
