Abstract: A process for handling interleaved sequences using RNNs includes receiving data of a first transaction, retrieving a first state (e.g., a default or a saved RNN state for an entity associated with the first transaction), and determining a new second state and a prediction result using the first state and an input data based on the first transaction. The process includes updating the saved RNN state for the entity to be the second state. The process includes receiving data of a second transaction, where the second transaction is associated with the same entity as the first transaction. The process unloops an RNN associated with the saved RNN state including by: retrieving the second state, determining a new third state and a prediction result using the second state and an input data based the second transaction, and updating the saved RNN state for the entity to be the third state.

Abstract: The present invention pertains to the technical field of oil and gas; more specifically to the field of risers and flow line connections to offshore structures, and describes a pull-in cable deflector system in keelhauling of rigid risers comprising: a deflector assembly including a deflector device housed in a structural block, a sliding structure, at least two rails. The deflector device installed in the structural block is moved through a sliding structure on rails installed forward of the URB to the different pull-in or pull-out positions in keelhauling of rigid risers. The structural block is slidably mounted on a base frame by means of a system of sliding supports to perform a first adjustment of the transverse distance from the deflector device to the URB. The deflector device is then rotated around the vertical line depending on the azimuth of the support tube. A second adjustment of the transverse distance of the deflector device is performed during the pull-in operation.

Abstract: A system and method is provided for direct condensing steam heating of oil sands process slurry streams including viscous bitumen froth and tailings products streams. Slurry viscosities greater than that of water increase cavitation and vibration issues. High solids content exacerbate component erosions. Difficult, and competing, steam and slurry interactions are managed by steam nozzle arrangements and management of steam injection at sub-sonic velocities based on a ratio of the slurry back-pressure Pb and steam supply delivery pressure Po.
