Abstract: The present application provides an aft plate removal tool for servicing a combustor. The combustor includes an aft plate with a central passage and a number of tubes extending through the aft plate. The aft plate removal tool includes a central screw, a lower housing attached to the central screw, the lower housing including a number of spring loaded lower housing feet, and an upper housing attached to the center screw, the upper housing including a number of spring loaded upper housing feet. The aft plate removal tool is inserted through the central passage of the aft plate such that rotation of the upper housing advances the spring loaded upper housing feet against the aft plate until the spring loaded upper housing feet push the aft plate off of the tubes.

Abstract: Machine learning model searching using meta data is provided. A system receives, via a graphical user interface from a client device, a request to search for one or more blueprints including one or more models to add to a project. The system can identify, based on a selection, a list of features with which to execute the requested search. The system can provide a blueprint including a model selected from projects established via input from client devices different from the client device, the projects including blueprints, the blueprints including models trained by machine learning. The system can train, via machine learning, the model of the blueprint to determine the target and add the blueprint including the trained model to the project. The system can generate data causing the graphical user interface to display an indication of the blueprint including the trained model.

Abstract: This disclosure relates generally to using machine learning models to generate current time-series features using machine learning and validate time-series machine learning model output. At least one aspect is directed to a system with one or more processors, coupled to memory, to segment a time series range into a first segment for an instance of time, the segment associated with a value for a target feature and a timestamp for the value, segment the time series range into an input segment associated with a plurality of input features and a segment timestamp less than or equal to the timestamp, generate a model trained with input comprising values for the target feature and timestamps for the values less than or equal to the segment timestamp, and transform at least one of the input features based at least on the model.

Abstract: Systems and methods of epidemiological modeling using machine learning are provided, and can include receiving values for an occurrence of the infectious disease during a first time period, generating, from a model trained by a machine learning system, predictions for the occurrence of the infectious disease over a second time period, performing, by a simulator using the predictions, one or more simulations of the occurrence of the infectious disease in one or more geographic regions during one or more time periods subsequent to the second time period, and providing, to a user interface, a first simulation of the one or more simulations performed by the simulator for a first geographic region of the one or more geographic regions during a time period of the one or more time periods.

Abstract: Methods and systems are provided for enhancing crankcase ventilation in a boosted engine. During boosted conditions, a crankcase may be ventilated via vacuum generated at an aspirator coupled in a compressor bypass passage. However, when the aspirator is plugged, pressure in the crankcase may be relieved by flowing crankcase gases through an aspirator bypass passage.

Abstract: Methods and systems are provided for ventilating a crankcase in an engine. In one example, when the engine is operating boosted under cruising conditions, fuel vapors from the crankcase may flow to each of a compressor inlet and an intake manifold of the engine. In this way, the crankcase may be effectively purged.
