Abstract: One of the key challenges that entities face when adopting data lakehouse for data storage is selecting a storage format for their data. However, choosing a single storage format to standardize is a difficult task, and entities often end up using different storage formats and different data processing services that may provide support for a particular storage format but not for the other. The disclosure addresses these challenges by recognizing the fact that different data storage formats are built on data files of the same type. The main differences are the metadata layer that stores metadata files describing the properties of these data files. The metadata for a second data storage format is automatically generated against a single copy of data files. As a result, entities can use the most suitable tool for each data workload and operate on a single data source, with interoperability across different storage ecosystems.

Abstract: A powdered adsorbent lossless recovery method based on a belt filter is provided. The lossless recovery method includes a first separation step of collecting a powdered adsorbent at a tail end of a belt filter. In the first separation step, at least a gas-water mixture fluid is used to flush a filter cloth to separate the powdered adsorbent from the filter cloth. In this disclosure, the separation manner of simple water washing used in the conventional technology is replaced with the manner that a gas-water mixture fluid is used to flush a filter cloth. Such a separation manner can not only save a large amount of liquid, but also reduce water content in a flushed powdered adsorbent suspension, so that the leakage of the powdered adsorbent is greatly reduced during transportation, to improve the recovery rate of the powdered adsorbent.

A cleaning portion, and a cleaning cavity for containing a ground cleaning device are formed in the base. The cleaning portion is used for cleaning at least part of the ground cleaning device.

The overall structural size of the cleaning base is reduced. The tap water source can continuously supply water to a cleaning tank. Thus, a user does not need to manually add water to the water storage structure.

Abstract: This disclosure relates generally to CT x-ray imaging systems and methods, and particularly to an inverse geometry with tetrahedron beams. Specifically, a dose efficient and controllable inverse geometry tetrahedron beam CT imaging is disclosed. The disclosed CT geometry includes a linear array of x-ray sources perpendicular to a rotation axis of the CT system and rotates together with a linear detector array extended parallel to the rotation axis. The x-ray emission from each of the sources is collimated into a fan-shaped beams projected to the linear detector array. The intensity of each beam is dynamically adjusted and controlled during the rotation of the source array and the detector array. Such a configuration provides control of x-ray intensity over a selected region of interest in a target object during the rotation even if the region of interest is off from the rotation axis, with efficient dose control.
