RESEARCH ON RIVER-LAKE DEMARCATION TECHNOLOGY FUSING RADAR POINT CLOUD ANDORTHOPHOTO

In the demarcation of rivers, lakes and water conservancy projects, whenthe airborne lidar point cloud data is used alone to automatically filter andclassify, low vegetation points are easily misclassified and misjudged as groundpoints,affected by the dense Pressure Switch distribution of vegetation in the measured area, thusresulting in the failtu

Pulsating jets Loungewear are very common and sometimes useful in industrial fields, due to some differences in basic characteristics from steady jets.In this research, the authors focus upon the mechanism of the frequency effect on a finite-amplitude pulsating jet.Experiments are conducted at a Reynolds number of 5,000, Strouhal numbers of 0.13, 0
