Abstract: A cigar tobacco leaf harvesting maturity identification method and system based on integrated learning are provided. The method comprises: acquiring an image of a cigar tobacco leaf to be detected, and preprocessing the image of the cigar tobacco leaf to be detected; carrying out vectorization dimensionality reduction on the preprocessed image of the cigar tobacco leaf to be detected, and extracting RGB and HSV eigenvalues to obtain a feature set; carrying out feature dimensionality reduction on data in the feature set by using a Wrapper algorithm to obtain an initial data set of the image of the cigar tobacco leaf to be detected; and inputting the initial data set into a trained random forest model, and outputting a maturity identification result of the image of the cigar tobacco leaf.

Abstract: A flow guide apparatus includes an upper flow guide structure configured to receive a first gas from a remote source, and a lower flow guide structure attached to the upper flow guide structure. The upper flow guide structure and the lower flow guide structure are configured to receive at least one gas from at least one remote source. The flow guide apparatus further includes a line diffuser structure disposed between the lower flow guide structure and the upper flow guide structure. The line diffuser structure has a long axis along a length of the upper flow guide structure and a short axis. The line diffuser structure includes a plurality of through holes that are configured to approximately evenly distribute the at least one gas as it is output into a reactor.

Abstract: Apparatus and methods for processing substrates using a gas injector unit with a quartz plate are provided. The gas injector unit comprises an injector body with a first opening extending through the injector body. The first opening has a nut portion and a clamp portion. A nut is positioned within the nut portion spaced from the injector body by a spring. A clamp is positioned within the clamp portion, which may be remotely located on a hub for connection with the injector body. A screw extends through the opening in the clamp, a portion of the injector body, the spring and into a connection portion of the nut. Gas distribution assemblies and processing chambers incorporating the gas injector unit are also described.

Abstract: Embodiments described herein provide a chamber having a gas flow inlet guide to uniformly deliver process gas and a gas flow outlet guide to effectively purge process gasses and reduce purge time. The chamber includes a chamber body having a process gas inlet and a process gas outlet, a lid assembly, a process gas inlet and a process gas outlet configured to be in fluid communication with a processing region in the chamber, a gas flow inlet guide disposed in the process gas inlet, and a gas flow outlet guide disposed in the process gas outlet. The gas flow inlet guide includes a flow modulator and at least two first inlet guide channels having first inlet guide channel areas that are different. The gas flow outlet guide includes at least two first outlet guide channels having first outlet guide channel areas that are different.

Abstract: A wave disc engine apparatus is provided. A further aspect employs a constricted nozzle in a wave rotor channel. A further aspect provides a sharp bend between an inlet and an outlet in a fluid pathway of a wave rotor, with the bend being spaced away from a peripheral edge of the wave rotor. A radial wave rotor for generating electricity in an automotive vehicle is disclosed in yet another aspect.
