Dam safety is an important basic part of national water network security. Building a dam deformation prediction model based on monitoring data crucial to ensure safety. However, traditional statistical regression methods have shortcomings, such as weak nonlinear fitting ability when constructing and models. The residual the results usually contains parts that cannot be effectively explained by ...

This study proposes a method for evaluating crack variations on structural performance of concrete dams using observational and computational output. The is represented by the system entropy in dams, stress-strain field established incorporating observations simulations calculations. Considering characterization ability sample points, weighted sequence constructed with selected index system. Th...

This paper conducts a research on the wavelet construction and application of image edge detection. Taking detection algorithm based modulus maxima as subject, this discusses problem dislocation phenomenon, threshold selection, multi-scale fusion evaluation criterion in algorithm, proposes an improved self-adaptive hierarchical information amount vanishing moment. From angle symmetry, filter co...
