Abstract: The systems and methods disclosed herein receives artifacts generated using a first set of models within a multi-model superstructure. The multi-model superstructure includes a second set of models to test the first set of models. The multi-model superstructure dynamically routes the artifacts of the first set of models to one or more models of the second set of models by (i) determining a set of dimensions of the artifacts against which to evaluate the artifacts and (ii) identifying the models in the second set used to test the particular dimension. The second set of models then assesses each artifact against a set of assessment metrics. If an artifact fails to meet one or more assessment metrics, the second set of models generates actions to align the artifact with the set of assessment metrics.

Abstract: A reactor system and method for catalytic dehydrogenation of saturated C3-C6 hydrocarbons within a reactor placed within a reactor disengager, where the reactor is open at the bottom thereof and open to the disengager, and the exit riser from the reactor is not hard coupled to at least one downstream cyclone. This configuration permits controlling the amount of catalyst within the reactor by varying the level of catalyst in the reactor disengager outside the reactor and permits controlling total catalyst hold-up and/or weight hourly space velocity (WHSV) independently from catalyst flow from the catalyst regenerator.

Abstract: Methods and systems are provided for delimiting a gas plant during fluid catalytic cracking unit (FCCU) revamp as part of the olefin production system. These methods and system include a chiller unit in the gas concentration unit downstream of the FCCU. Other measures also include installing a stripper unit downstream of the regenerator of the FCCU or installing a quench line in a reactor of a FCCU to reduce the contact time of the hydrocarbon feedstock with the catalyst. These methods and systems may also lead to an increase in the propylene yield of the olefin production system.

Abstract: A joint distraction device that is wearable by a patient and user-friendly and associated methods of joint distraction. Such devices can include first and second anchors that secure portions of the patient's body proximal and distal of the joint, the anchors each being attached to a beam and a distance between first and second anchors being adjustable so as to hold the joint being investigated in distraction. For distraction of a wrist joint, the first anchor can be a finger clamp and the second anchor can be an arm sleeve. The finger clamp can include multiple finger traps. The distance between anchors can be adjusted by an adjuster, by extending the beam or by moving an anchor incrementally along the beam. Advantageously, the device is fully wearable by the patient without being attached to external components, thereby improving patient comfort, portability and ease of use.

Abstract: The present disclosure relates to a system, method, and computer program for extracting utterances corresponding to a user problem statement in a conversation between a human agent and a user. The system obtains a set of utterances from a natural language conversation between the human agent and the user. The system uses a problem-statement classifier to obtain machine-generated predictions as to whether each natural language utterance in the set relates to a problem statement. The system selects one or more utterances from the set as corresponding to a problem statement based on the predictions. The system provides the selected utterances to a downstream system for further processing. In certain embodiments, the problem statement classifier includes an encoder that creates an utterance embedding for each utterance and a prediction module that uses the utterance embeddings to predict whether each utterance corresponds to a user problem statement.
