Abstract: An unmanned aerial vehicle (UAV) can be configured for fire suppression and ignition. In some examples, the UAV includes an aerial propulsion system, an ignition system, and a control system. The ignition system includes a container of delayed-ignition balls and a dropper configured, by virtue of one or more motors, to actuate and drop the delayed-ignition balls. The control system is configured to cause the UAV to fly to a site of a prescribed burn and, while flying over the site of the prescribed burn, actuate one or more of the delayed-ignition balls. After actuating the one or more delayed-ignition balls, the UAV drops the actuated one or more delayed-ignition balls from the UAV onto the site of the prescribed burn.

Abstract: A computer program file or a sequence of processing steps from an authoring environment of a data processing system is used to generate a graph including nodes representing the processing steps is generated. Unique identifiers (tags) are assigned to the nodes. One or more processing steps are optionally modified while preserving the original identifiers. If an error occurs during execution, error information is saved including the processing step that failed and data records that triggered the failure. The identifier of the failed processing step is attached to the error information. The error information is collected and processed. The collected error information is used to correlate the error to the failed processing step and to data records triggering the error using the identifier of the failed processing step recorded with the error information. The correlated error information indicates cause and location of the error.

Abstract: The present application provides a turbine rotor blade including an airfoil shape and a trailing edge shape. The airfoil shape may have a nominal profile substantially in accordance with Cartesian coordinate values of X, Y and Z set forth in Table I, while the trailing edge profile is defined by Table II. The Cartesian coordinate values of X, Y and Z are non-dimensional values from 0% to 100% convertible to dimensional distances expressed in a unit of distance by multiplying the Cartesian coordinate values of X, Y and Z by a height of the airfoil in the unit of distance (e.g., inches). The X and Y values, when connected by smooth continuing arcs, define airfoil profile sections at each distance Z. The airfoil profile sections at Z distances may be joined smoothly with one another to form a complete airfoil shape.

Abstract: A computer-implemented method is disclosed that comprises receiving, at a data provider computing system, a data contribution from a client device associated with a user, and based on the received data contribution, determining a user identifier that uniquely identifies the user. The method comprises performing a data validation operation to validate the data contribution. The method comprises, based on validating the data contribution, storing the data contribution in association with the user identifier. Further, the method comprises receiving a data request from a data consuming system. Based on the data request, the stored data contribution is identified and distributed to the data consuming system. Based on distribution of the data contribution to the data consuming system, a distribution value associated with the data contribution is generated. An indication of the distribution value is stored in association with the user identifier.

Abstract: A multiple screw extruder (50) combines application of vacuum to a vacuum vent (62) positioned between material feed locations (70, 72) of the extruder and use of specially configured extruder screws (58) to extract gases, primarily air, out of the extruder to densify the materials introduced into it and to extract unwanted fluid from material introduced for mixture with molten polymeric material flowing through the extruder. The multiple screw extruder is operationally versatile in that it is capable of carrying out the material densification and fluid extraction processes either separately or simultaneously. Implementation of the disclosed vacuum feed technology provides an increase in rate of extrudate throughput as compared with that achievable by implementation of atmospheric venting (16) in a conventionally configured extruder (10a, 10b).
