Abstract: A rotating detonation combustor includes a nozzle coupled to the combustor body at or near the exhaust opening to choke the exhaust opening. A rotating detonation combustor may include a diverting plate positioned radially inward of the inlet annulus and inlet channels for diverting flow of a mixture in an axial direction. A rotating detonation combustor may include a combustor body including an outer shell at least partially defining a detonation combustion chamber and extending axially from a base toward an exhaust opening of the detonation combustion chamber. The base defines a passageway in fluid communication with the detonation combustion chamber and includes an inlet annulus for axially directing a second fluid into the passageway and a plurality of inlet channels for radially directing a third fluid into at least one of the passageway or the detonation combustion chamber, and the detonation combustion chamber is free of any inner body.

Abstract: Systems and methods for a vision-based machine learning model for lane connectivity in autonomous or semi-autonomous driving. An example method includes obtaining images from a multitude of image sensors positioned about a vehicle; compute forward pass-through backbone networks of a machine learning model, wherein the output of the backbone networks are fused via a transformer network; aggregating information output from the transformer network across time and/or space; and determining lane connectivity information.

Abstract: Systems and methods for a vision-based machine learning model for autonomous driving with adjustable virtual camera. An example method includes obtaining images from a multitude of image sensors positioned about a vehicle. Features associated with the images are determined, with the features being output based on a forward pass through a first portion of a machine learning model. The features are projected into a vector space associated with a virtual camera at a particular height. The projected features are aggregated with other projected features associated with prior images. A plurality of objects which are positioned according to the virtual camera are determined.

Abstract: In one embodiment, a combustor includes a nozzle coupled to the combustor body at or near the exhaust opening to choke the exhaust opening. In another embodiment, a combustor includes a diverting plate positioned radially inward of the inlet annulus and inlet channels for diverting flow of a mixture in an axial direction. In another embodiment, a combustor includes a combustor body including an outer shell at least partially defining a combustion chamber and extending axially from a hollow base toward an exhaust opening of the combustion chamber. The hollow base defines a passageway in fluid communication with the combustion chamber and includes an inlet annulus for axially directing a first fluid into the passageway and a plurality of inlet channels for radially directing a second fluid into at least one of the passageway or the combustion chamber, and the combustion chamber is free of any inner body.
