Abstract: The present invention relates to the technical field of catalyst preparation, disclosing a preparation method and application of a coated vanadium-tungsten-titanium oxide monolithic SCR catalyst. The method includes the steps of mixing a vanadium oxide precursor, a tungsten oxide precursor, titanium dioxide, an inorganic adhesive, an organic adhesive and a macromolecular surfactant with deionized water and stirring them to obtain a thick liquid; adding a pH adjuster to the thick liquid to make its pH 1.5-4.5; impregnating a cordierite honeycomb carrier in the thick liquid to obtain a preliminarily-impregnated catalyst and dried and calcined the preliminarily-impregnated catalyst to obtain a finished catalyst. The method has advantages such as simple operation, easy repetition and short time-consuming, so it can be applied to exhaust gas post-treatment of a marine diesel engine, and provide a good choice for catalysts used to denitrify medium and high temperature exhausted gas from marine engines.

Abstract: Methods, systems, and apparatus, including computer-readable media, for authentication enhanced data indexing and searching. In some implementations, a search service is configured to receive and process queries from a plurality of different application servers, where each application server has an associated data repository. The search service receives a query associated with a user of a client device. The search service provides the query to a search backend having a search index for the plurality of application servers, where the search index describes contents of each of the respective data repositories of the application servers. Search results are received from the search backend, including search results representing data elements from different data repositories of the different application servers. At least some of the search results are provided as an output of the search service as a response to the query.

In a particular composition, the water-soluble plant nutrient comprises urea, the binding material for the core comprises corn starch, the hydrogel for the coating layer comprises corn starch hydrogel, the core has a thickness of 2.5-3.5 mm and a closed porosity of 0.05-3%, and the coating layer has a thickness of 1.35-1.5 mm and a closed porosity of 0.1-5%.

Abstract: The present disclosure relates to an action recognition method, an electronic device, and storage medium. The action recognition method includes: detecting a target part on a face in a detection image; capturing a target image corresponding to the target part from the detection image according to the detection result for the target part; and recognizing, according to the target image, whether the object having the face executes a set action. Embodiments of the present disclosure are applicable to faces of different sizes in different detection images, and are also applicable to faces of different types. The embodiments of the present disclosure have a wide application range. Not only the target images may include sufficient information for analysis, but also the problems of low system processing efficiency caused by oversized captured target images and excessive useless information are reduced.

Abstract: An action recognition method and apparatus, a driving action analysis method and apparatus, and a storage medium are provided. The method includes: extracting a feature in an image including a human face; determining, on the basis of the feature, a plurality of candidate boxes including a predetermined action; determining an action target box on the basis of the plurality of candidate boxes, where the action target box includes a face local region and an action interactive object; and categorizing the predetermined action on the basis of the action target box to obtain an action recognition result.

Abstract: A method for recognizing a dangerous action of personnel in a vehicle, an electronic device, and a storage medium are provided. The method includes: obtaining at least one video stream of the personnel in the vehicle through an image capturing device, each video stream includes information about at least one of the personnel in the vehicle; performing action recognition on the personnel in the vehicle based on the video stream; and responsive to that a result of the action recognition belongs to a predetermined dangerous action, performing at least one of: sending prompt information, or executing an operation to control the vehicle, wherein the predetermined dangerous action includes at least one of the following action representations of the personnel in the vehicle: a distraction action, a discomfort state, or a non-standard behavior.
