  • Publication number: 20220407940
    Abstract: The present invention discloses a service caching method for a cross-border service network, wherein the method includes: a cache space of a service switch node is divided into a resident area, a change area, a pre-reclaimed area and a maintenance index area; among them, a cache hit frequency is: a resident area>a change area>a pre-reclaimed area, and the maintenance index area is used for separate storage services call path. when a service call is generated, a cache content in the cache space is replaced according to a cache value of a missed cache or a hit cache; a service router and service switch nodes in the corresponding area jointly form a hierarchical cache mode. When the cache space of any node in the service switch node is insufficient, the service switch nodes in the same area perform collaborative cache and store them in other cache space of the service switch node through indexing.

  • Publication number: 20220375220
    Abstract: A visual localization method and apparatus are provided. The method includes obtaining a captured first image, determining a first pose based on the first image and an aerial model, determining whether a ground model corresponding to the first pose exists in an aerial-ground model, and when the ground model corresponding to the first pose exists, determining a second pose based on the ground model. The aerial-ground model includes the aerial model and the ground model mapped to the aerial model, a coordinate system of the ground model is the same as a coordinate system of the aerial model, and localization accuracy of the second pose is higher than localization accuracy of the first pose. Performing fine visual localization based on the ground model can improve accuracy and a success rate of localization.

  • Patent number: 11428677
    Abstract: The present invention provides a reference fingerprint of virgin olive oil, and an establishment method and an application thereof. By using UPLC-FLD, the chromatographic information of various components in the extra virgin olive oil is obtained, breaking through the limitation of establishment of fingerprints by means of conventional GC-MS method and based on the fatty acid composition of edible oil, and further solving the problem that traditional fingerprints only use a single component for determination and thus result in false positivity.

  • Publication number: 20220266326
    Abstract: Flanges formed on sheet metal parts to increase the part stiffness or create mating surface for further assembly are created in an incremental sheet forming process using forming tool and supporting tool that move along a specified tool path so as to gradually deform a peripherally-clamped sheet metal work piece into the desired geometry. With two universal tools moving along the designed toolpath on the both sides of the part, the process is very flexible. Process time is can also be reduced by utilizing an accumulative double-sided incremental hole-flanging strategy, in which the flange is formed in only one step.

  • Publication number: 20210303371
    Abstract: Methods, systems, and computer programs encoded on computer storage media, for processing user-defined functions in containers One example system receives a query written in a primary query language that calls a user-defined function. The system assigns primary segment hosts to process portions of the query written in the primary query language and assigns first containers to process the call to the user-defined function. The primary segment hosts provide to the first containers the user-defined function and one or more arguments in the call to the user-defined function. The first containers execute the user-defined function. The primary segment hosts receive an initial result of the call to the user-defined function computed by the first containers. The primary segment hosts compute a final result of the query using the initial result. The primary segment hosts provide the final result of the query in response to receiving the query.
