Abstract: An application-level memory control group of a first application may be created when the first application is opened. An anonymous page of the first application is added to a least recently used linked list of the application-level memory control group, and a file page of the first application is added to a global least recently used linked list. An application-level memory control group is created in a dimension of an application, and an anonymous page of the application is managed in a refined manner. In addition, a file page of the application-level memory control group may be managed based on a global least recently used linked list.

Abstract: A method of controlling access to components of an SDDC in a hybrid environment, the hybrid environment including a cloud platform from which cloud services are delivered to the SDDC through agents deployed on an agent platform appliance, includes the steps of: transmitting to a first component of the SDDC, a request to create a first account for accessing the first component of the SDDC by a first agent, which is one of the agents deployed on the agent platform appliance; in response to the first agent requesting access to the first component of the SDDC, transmitting to the first component of the SDDC, credentials associated with the first account and a request for a first authentication token that authorizes the access to the first component of the SDDC; and upon receiving the first authentication token from the first component of the SDDC, transmitting the first authentication token to the first agent.

Abstract: A method for forming a large-diameter special-shaped cross section thin-wall tubular part. A tailor welded barrel blank is adopted as an original blank for forming of the large-diameter special-shaped cross section thin-wall tubular part. After a desired shape is formed, the original weld joint is removed and butt joint tailor welding is performed on the tubular part again. Since the tailor weld joint of the original barrel blank is removed from the final part, there is no need to consider the consistency or coordination of the microstructure of the weld joint and the base metal during the forming process and the subsequent thermal treatment process.

An elastic piece is disposed om an inner surface of the one end of the cover rotatably connected with the box body. One end of the elastic piece is fixed on the box body. Another end of the elastic piece of the covers is buckled with one side of the pill storage cavity of the box body.

Abstract: A storage system, a file storage and reading method, and a terminal device are provided. A storage system including a UFS is used as an example. The storage system configures different medium forms of the UFS, for example, configures persistent storage space of the UFS including SLC and TLC medium forms, to implement hybrid medium multi-disk storage. Based on the storage system, a hot file related to an application running rate is preferentially selected and stored in an SLC storage area of the UFS, and files on a mapped multi-disk are mounted on a same directory of a file system, so that files can be migrated between the SLC storage area and a TLC storage area without user perception, to improve performance of the storage system.

Abstract: A system, apparatus, computer program product, and method use a convolutional neural network to auto-determine a first floor height (FFH) and a FFH elevation (FFE) of a building. The FFH, and FFE of the building are determined with respect to the terrain or surface of the parcel of land on which the building is located. In turn, by knowing the FFH and/or FFE of the building on the parcel, it is possible to use that information while performing a flood risk assessment to a property without requiring a personal inspection of the parcel by a human.

Abstract: Laser additive manufacturing and a method for preparing thin-walled preforms by laser metal deposition and follow-up rolling. This can solve the problems that when the existing laser metal deposition technology prepares the thin-walled preforms, the limit width size of a molten pool at high power affects the forming wall thickness of the preforms so that it is difficult to prepare preforms with wall thickness less than 2 mm, and the problems of poor surface quality and low accuracy of preforms due to convex and concave peaks caused by the interlayer overlapping, but also can solve the problems that a laser beam with a preset trajectory cannot act on the end surfaces of the preforms due to preform deformation caused by residual stress in a printing process so that the preforms cannot be continuously formed.
