Abstract: A standalone website order after-sales method and apparatus, a device and a medium, the method including: receiving an order generation request sent by user equipment, where the order generation request includes a commodity identification and a user identification; generating a commodity order according to the order generation request; sending the commodity order to the user equipment to enable the user equipment to complete payment for the commodity order; in response to a completion of the payment for the commodity order, generating an after-sales token corresponding to the commodity order; sending a commodity order confirmation email to a user mailbox corresponding to the user identification, where the commodity order confirmation email includes an after-sales link of the commodity order, and the after-sales link includes the after-sales token corresponding to the commodity order.

Abstract: Disclosed is a method for analyzing wind turbine blade coating fatigue due to rain erosion. According to the method, a stochastic rain field model is established, and the coating fatigue life of the wind turbine blades is calculated based on a crack propagation theory. The present patent innovatively develops a stochastic rain field model considering the shape, size, impact angle, and impact speed of raindrops to simulate the raindrop impact process, analyzes the impact stress of raindrops on the blade coating by using a smooth particle hydrodynamics method and a finite element analysis method, calculates the impact stress of all raindrops in the random rainfall process by using a stress interpolation method, and carries out fatigue analysis for the blade coating based on the impact stress.

Abstract: A system and method are disclosed for high performance message passing between an origin computing node and a target computing node. A target progress thread is caused to receive a message from an origin process user thread to initiate a one sided communication operation. A target copy buffer of a target process thread is caused to respond to the received message for assisting in completing communication operations.
