Abstract: A modular blade connection structure includes a first module, a second module and a structural adhesive module. The first module is provided on an end face thereof with a bonding flange extending into the second module; a gap between the butting surfaces of the first module and the second module is injected with a structural adhesive, which is extruded and cured to form a structural adhesive module; and the thickness of the first module at the starting end of the bonding flange extends towards the inner surface to form a first reinforcement, and the structural adhesive module extends inside the second module in a direction away from the bonding flange to form a second reinforcement. The present disclosure facilitates the control the bonding quality of the double-sided overlapping of the modular blade by means of the bonding flange and the improvement of the fatigue resistance at the assembling position.

Abstract: A controller obtains data stored in one or more data structures generated based on a defined task to be performed for a selected event. The data includes a set of constraints for the defined task. One or more task solutions generated for the defined task using the provided data are obtained. A determination is made as to whether the one or more task solutions include a task solution that satisfies one or more defined criteria. Based on determining that the one or more task solutions do not include the task solution that satisfies the one or more defined criteria, the set of constraints is automatically adjusted to provide an adjusted set of constraints. The adjusted set of constraints is to be automatically provided to a solution generator to be used to obtain the task solution that satisfies the one or more defined criteria.

Abstract: Trusted execution environment construction is described and includes obtaining regulatory requirement information of a trusted execution environment. The regulatory requirement information is parsed to obtain atomized security function information applied to the trusted execution environment. Formal parsing processing is performed on the security function information to obtain a security solution of the trusted execution environment to prove that it satisfies the regulatory requirement information and generating a test case corresponding to the security solution based on an axiom of the security solution. Using a predetermined property migration mechanism based on the security solution and the test case corresponding to the security solution, a trusted execution environment is constructed that has same property information as the security solution and the test case with respect to a predetermined property item in a target scenario.

Abstract: Disclosed are an online monitoring system for a crack on a hoist spindle and an operation method thereof. The system comprises: a rope power part, a crack detection part, a wireless transmission part, and a computer. The rope power part comprises two traction ropes, two guide wheels, two stepper motors, and two stepper motor drivers. The crack detection part comprises a spiral tube guide rail, a sliding body, and an ultrasonic generator. The wireless transmission part comprises three zigbee wireless sensing modules. The zigbee wireless sensing modules receive instructions from the computer and transmit the instructions to the stepper motor drivers to control the motors to rotate. The stepper motors drive the guide wheels to rotate to realize the winding of the ropes, so as to pull the sliding body to slide on the spiral tube guide rail. The ultrasonic generator clamped on the sliding body monitors the rotating spindle along the spiral tube guide rail.
