Abstract: The present application discloses a data resource health maintenance method and apparatus, and a device. The data resource includes data computing resource and data storage resource. The method includes: obtaining a health assessment indicator for assessing health of the data resource, wherein the health assessment indicator includes a resource effective utilization degree and a resource risk level of the data resource in a use process; determining a weight corresponding to the resource effective utilization degree and a weight corresponding to the resource risk level; obtaining a health assessment result of the data resource based on the resource effective utilization degree, the resource risk level, the weight corresponding to the resource effective utilization degree, and the weight corresponding to the resource risk level; and obtaining a data resource use event related to the health assessment result, and performing data resource governance based on the data resource use event.

Abstract: A method and an apparatus for assessing a risk caused by improper use of a cluster data resource, an electronic device and a storage medium are provided. A high-risk diagnosis indicator in a storage assessment dimension and a high-risk diagnosis indicator in a computation assessment dimension are obtained. The amount of high-risk diagnosis indicators in the storage assessment dimension that are satisfied in the use process of the data storage resource and the amount of high-risk diagnosis indicators in the computation assessment dimension that are satisfied in the use process of the data computation resource are counted, and are recorded as high-risk indicator trigger quantities. Risk on the data storage resource is assessed based on the high-risk indicator trigger quantity in the storage assessment dimension, and risk on the data computation resource is assessed based on the high-risk indicator trigger quantity in the computation assessment dimension.

Abstract: Embodiments of the present disclosure provide a method for evaluating a cost of a cluster data resource, a storage medium, and an electronic device. And the method includes: a storage evaluation index in a storage evaluation dimension and a computing evaluation index in a computing evaluation dimension for evaluating a cost of a cluster data resource are obtained. The data storage resource cost is evaluated based on an index value of the storage evaluation index, and the data computing resource cost is evaluated based on an index value of the computing evaluation index. In this way, invalid use and low-efficiency use in the cluster data resource are distinguished, so that the evaluation of the cost of the cluster data resource is more accurate.

Abstract: A low-pressure aluminum casting mold and a low-pressure aluminum casting process for a motor rotor. The low-pressure aluminum casting mold includes an upper blade profile assembly, a lower blade profile assembly, a rotor core, a dummy shaft and a diverter. The upper blade profile assembly includes an upper backing plate and an upper mold, and the lower blade profile assembly includes a lower backing plate and a lower mold. The low-pressure aluminum casting mold further includes a first pressing device and four sets of second pressing devices. The low-pressure aluminum casting process includes the steps of cold lamination, heating of the rotor core, mold preparation, hot lamination, and low-pressure casting.

Abstract: A blockchain-based interconnected vehicle authentication system and method. During message signature process, a registered vehicle verifies a driver, and broadcasts a message. During a message verification process, a registered vehicle checks the message authentication code from a received message based on the system key, and verifies the message based on a public key of a sender of the message. During a block generation and verification process, the first local trust authority broadcasts a block, and share the block to the second local trust authorities after the block passes verification. During a block confirmation process, second local trust authority makes confirmation with regard to the block and send a confirmation result to the root trust authority, to allow the root trust authority link the block into the blockchain in response to receiving confirmation results from second local trust authorities in a quantity exceeding a predetermined number.
