    • A method and system for producing fluid from a subsea wellbore. An amount of fluid is sampled from fluid being produced and retained for a period of time until constituents in the fluid stratify. A fluid characteristic is sensed at spaced apart vertical locations in the sampled fluid. A water fraction as well as gas content can be ascertained from sensing the sampled fluid. The fluid characteristic is used for calibrating a multi-phase flowmeter that measures flow of the fluid being produced from the wellbore.
    • 一种用于从海底井筒生产流体的方法和系统。 从产生的流体中取出一定量的流体,并保持一段时间,直到流体中的成分分层。 在采样流体中的间隔开的垂直位置处感测流体特性。 可以从感测采样的流体确定水分和气体含量。 流体特性用于校准测量从井筒产生的流体的流量的多相流量计。

    • A wellhead system for producing hydrocarbons from a subterranean formation that includes concentric tubulars that form an annulus. The annulus is vented by flowing fluid from the annulus through a bleed line having a valve that is selectively opened and closed. Upstream of the bleed line valve, the bleed line is routed adjacent a production flow line. The temperature of the fluid in the production flow line is greater than annulus temperature and warms the bleed line. Hydrate formation in the bleed line is thereby inhibited by the thermal energy it receives from the production flow line.
    • 一种用于从地层形成烃的井口系统,其包括形成环的同心管。 通过将流体从环形空间通过具有选择性地打开和关闭的阀的排放管排出。 在排气阀门的上游,排放管路在生产流水线附近路线。 生产流水线中的流体温度大于环空温度并加热出气管线。 因此,通过从生产流水线接收的热能来抑制排出管线中的水合物形成。

    • Systems and techniques for generating item ratings for a user in order to allow for recommendations of selected items for that user. A set of known ratings of different items for a plurality of users is collected and maintained, and these known ratings are used to estimate rating factors influencing ratings, including user and item factors. Initial user and item factors are estimated and new user and item factors are successively added, with the original rating factors being progressively shrunk so as to reduce their magnitude and their contribution to the rating estimation as successive factors are added. When an appropriate number of user and item factors has been estimated, the rating factors are used to estimate ratings of items for a user, and the estimated ratings are employed to generate recommendations for that user.
    • 用于为用户生成项目评级的系统和技术,以便允许针对该用户的所选项目的推荐。 收集和维护一组用于多个用户的不同项目的已知评级,并且使用这些已知评级来估计影响评级的评级因素,包括用户和项目因素。 初始用户和项目因素被估计,并且连续添加新的用户和项目因素,原始评级因子逐渐收缩,以便随着连续因素的增加而减小它们的大小和对评估估计的贡献。 当估计出适当数量的用户和项目因素时,使用评级因子来估计用户的项目的评级,并且使用估计的等级来为该用户生成推荐。

    • A method, apparatus, and computer-readable medium for predicting the fault-proneness of code units (files, modules, packages, and the like) of large-scale, long-lived software systems. The method collects information about the code units and the development process from previous releases, and formats this information for input to an analysis stage. The tool then performs a statistical regression analysis on the collected data, and formulates a model to predict fault counts for code units of the current and future releases. Finally, the method computes an expected fault count for each code unit in the current release by applying the formulated model to data from the current release. The expected fault counts are used to rank the release units in descending order of fault-proneness so that debugging efforts and resources can be optimized.

    • The present subject matter relates to data access and, more particularly, to data unification models. Some embodiments provide systems, software, and methods of handling data access requests for data items having values stored in multiple instances across one or more data sources. Some embodiments provide a data manager to service access requests for a data item, wherein the data manager services the data access requests for the data item with data from an authoritative instance or from one of one or more secondary instances. In some embodiments, the data manager services the request for the data item according to a data model. The data model, in some embodiments, exists in metadata that is accessible to the data manager.
