Abstract: A method includes obtaining, at a first data provider, a first query generation request. The method also includes determining whether a first query, that is to be generated based on the first query generation request, is approved. In response to a determination that the first query, that is to be generated, is approved, the method also includes generating the first query. The method further includes sharing the generated first query with a second data provider.

Abstract: Disclosed are methods and systems for providing a plurality of data corpuses for anonymization and aggregation. A plurality of data providers validate rules for accessing data by data requesters prior to data availability.

Abstract: A method of calculating radiation fluence and energy deposition distributions on a networked virtual computational cluster is presented. With this method, complex Monte Carlo simulations that require expansive equipment, personnel, and financial resources can be done efficiently and inexpensively by hospitals and clinics requiring radiation therapy dose calculations.

Abstract: An oil storage vessel (10) comprises a hull (12) of generally tubular form having a double wall defining one or more ballast chambers (14). The orientation of the hull (12) relative to water in which it is floated is controllable by adjusting the content of some or all of the ballast chambers (14). Thus, by suitable manipulation of the ballast chambers (14) the barge (10) may be caused to float generally horizontally, that is, with its longitudinal axis parallel to the surface of the water. In this position, it is particularly useful for transportation of the hull contents. Alternatively, the hull (12) may, be manipulation of the ballast chambers (14) be arranged with its longitudinal axis perpendicular to the surface of the water so that it can be used for collection and storage of liquids such as oil.
