Abstract: A comprehensive resilience evaluation system for a traditional village is provided. The system employs a deep learning-based neural network model to perform semantic encoding on data for resilience aspects of a traditional village to be evaluated to extract semantic descriptive coding features from the multi-dimensional data for the resilience aspects of the village to be evaluated. Concurrently, the system retrieves village resilience-related data labeled with a first resilience evaluation label from a backend database as reference features. Through conducting a semantic query matching analysis based on multi-source resilience-related data between the village to be evaluated and various villages labeled with the first resilience evaluation label, the system intelligently evaluates whether the village to be evaluated possesses a resilience level corresponding to the first resilience evaluation label.

Abstract: According to a turbine hydroelectric power generation device and a power generation method based on pressurized water inlet pipelines, after water flows are input into liquid inlet flow channels and guided by guide vanes, by arranging the liquid inlet flow channels that are the vortex-shaped spiral flow channels, it can be ensured that the water flows are evenly diverted by the guide vanes and thus are output to a driving rotor at the same flow velocity to impact and drive the driving rotor to rotate. The driving rotor can drive, during rotation, a power generation rotor to rotate inside a magnetic power generation mechanism to generate electricity, and the input water flows are finally collected by a bottom liquid discharge mechanism and then separated into multiple water flows to be output respectively.
