Abstract: Systems and methods for modeling subterranean formations that include both gaseous hydrocarbons and adsorbed hydrocarbons. The systems and methods include determining a formation volume factor for gaseous hydrocarbons that may be present within the subterranean formation and correcting the formation volume factor to generate a compensated formation volume factor. The systems and methods further may include simulating a fluid flow within the subterranean formation, with the simulating being based, at least in part, on the compensated formation volume factor. Correcting the formation volume factor may include adjusting the formation volume factor based, at least in part, on a fraction of the adsorbed hydrocarbons within the subterranean formation that desorbs from the subterranean formation and/or transitions to gaseous hydrocarbons during production of the gaseous hydrocarbons from the subterranean formation.

Abstract: The subject of this patent is a system and method for assessing students' understanding while they are interacting with a plurality of third party educational systems. The system comprises (1) an application program interface (API) that allow any educational content provider to instrument their content with the proposed system, so that the interaction of students with the content can be tracked; (2) an inference engine that gathers and analyzes interactions across multiple students and a broad array of content, and infers both, the difficulty of each piece of content, and the understanding of each student; (3) a reporting tool for students or for educators following a group of students, expressing the level of understanding of each student and its progression over time.

Abstract: A user interface method and apparatus for an electronic device operates by detecting a stroke (20) of a touch sensitive display (10) forming a part of the electronic device. The stroke is interpreted by the user interface method (73) as a sequence of commands where each command is associated to one edge traversed by the stroke, and possibly to the direction and to the speed at which the input device crossed the edge. The touch sensitive display (10) can be shared between the user interface method and any other application. If a stroke does not traverse any edges or is identified by other means as irrelevant for the user interface method, it is translated into an application function.
