Latest Patents

Xie is associated with 1 patent, titled “Partition Monitoring Method and Model for Concrete Dam Operation Key Part.” The method uses time-frequency vectors extracted from monitoring data to partition key areas of a concrete dam. It then organizes time-series measurements from different monitoring instruments into a graph structure, capturing relationships across both time and variables. A graph attention network helps learn and represent these relationships, and the resulting features are used to calculate anomaly scores. By comparing measurements from multiple instrument types and locations, the approach supports anomaly detection while reflecting the dam’s structural integrity and spatial distribution.
