Abstract: An aviation blade profile chord length measurement method and system based on secant rotation iteration, relating to the field of aviation blade profile measurement. The method comprises: taking a connection line between two farthest points in a blade profile contour point set as a secant, rotating or translating the secant to enable the secant to intersect with a blade basin, and obtaining a leading edge point set and a trailing edge point set; rotating the secant within the range of the leading edge point set and the trailing edge point set to obtain tangent points of the secant and the leading edge and the trailing edge, and calculating the distance between the two tangent points to obtain the chord length. The calculated chord length is high in accuracy; the size of the blade can be controlled by means of the chord length of the blade, and if the chord length is too short, the strength of the blade is reduced, thereby affecting the impact resistance and the aerodynamic performance of the blade; thus, the aerodynamic performance and safety of the blade can be ensured when the chord length of the blade is measured using the method.

Title: Sharding for workflow applications in serverless architectures
Inventor: CHANG SHUAI
IPC: G06F16/27
Filed: 2020-08-12
Abstract: Systems and methods provide a multi-version shard plan to improve horizontal scaling and load balancing across distributed shards while avoiding downtime resulting from data migration. According to serverless architectures, application hosting services providers may provision customers with distributed computing resources partitioned into shards, which may be dynamically assigned, scaled, and load-balanced for architecture-agnostic workflow applications. A versioned shard plan may be implemented at a database, storing key ranges which enable workflow application executions to be uniquely mapped to particular shards. The database controller may immutably assign a shard to each execution of a workflow application, and publish a new version of the shard plan accessible to both a frontend and a backend of the customer's hosted applications. By these solutions, in the course of horizontal scaling of computing resources assigned to workflow applications, data migration between shards is avoided and downtime may not be incurred as a result.
