Abstract: System and methods for generating microseismic velocity models are provided. One or more existing well sites in proximity to a planned well site are selected. Historical microseismic velocity models associated with the selected well sites are obtained. The formation depths for each velocity component of the historical models are correlated to formation depths from well logs acquired for a subsurface formation associated with the planned well site. A classification and non-linear regression on the historical microseismic velocity models is performed to identify the best-fitting velocity components for layers of the subsurface formation corresponding to the correlated formation depths. An initial microseismic velocity model of the formation is generated using the best-fitting velocity components. Seismic wave propagation through each layer of the formation is simulated using the generated model.

Abstract: A method of displaying media content through a user interface of a communication device using an Activity-based Overlay technique. The method includes detecting a first user interaction with a user interface and responsively initiating a timer, the timer being configured to expire upon elapsing of a predefined delay period. An Overlay containing the media content is then rendered on a display of the user interface. The method further includes monitoring, during the predefined delay period, the operating system in order to detect a second user interaction with the user interface. Upon expiration of the timer, it is determined whether a detection of the second user interaction with the user interface occurred during the predefined delay period. A backing Activity associated with the Overlay is then invoked based upon this determination.

Abstract: A communication device configured to unobtrusively display media content. The processor receives an indication of a state transition of a first Activity and detects a first user interaction with the user interface, which may be done by inspecting a first operating system method called in relation to the first Activity. Upon determining the first Activity is finishing, the processor displays the media content. A backing Activity is then invoked behind the media content on a z-axis of the display wherein the operating system delays execution of the backing Activity for a predefined delay period subsequent to the selection of the user interface element. A second user interaction with the user interface is detected by inspecting a second operating system method called in relation to the backing Activity. The display of the media content is terminated upon the detection of the occurrence of the second user interaction.

Abstract: A method for displaying rich media content through a user interface of a communication device. A first user interaction with the user interface is detected and it is determined, based partly upon detection of the first user interaction, that a first Activity of a plurality of Activities is finishing. An Overlay containing the media content is then rendered on the device display. The Overlay is associated with a backing Activity, the device operating system delaying execution of the backing Activity during a delay period initiated in response to the first user interaction. The method further includes inhibiting Activity-supported functionality of the Overlay facilitated by the backing Activity. A context object associated with the Overlay is created to contain an Activity context associated with a state of the Overlay during the delay period. The Activity context is transferred to the backing Activity and Activity-supported functionality of the Overlay enabled.

The View container is painted on the display to thereby render the media content on the display. A second system broadcast is generated by the operating system is received. The second system broadcast indicates the first user interface element has been again selected. The View container is then removed from the memory, thereby terminating rendering of the media content on the display.

Abstract: Described are techniques for reducing inaccurate values in databases by managing the order in which processes are enqueued and executed. A modification process to modify a first value in a database may be received. A precomputation process that modifies values dependent on the first value may be enqueued prior to enqueuing of the modification process to ensure that the modification process does not occur if the precomputation process fails. The modification process may be executed prior to executing the precomputation process to ensure that the precomputation process acts to modify the dependent values using the modified version of the first value.
