Simulation of Storm Runoff Under Different Recurrence Periods in Jinfeng District of Yinchuan
Published 2022-01-01“…Visual simulation of urban storm runoff can reveal the spatiotemporal laws of urban catchment runoff,node overflow,pipe network drainage,and waterlogging risk under different recurrence periods.This research selected the central part of the Jinfeng District in Yinchuan,China,as the study area.Runoff in each sub-catchment,drainage capacity of the pipe network,and the urban waterlogging risk under different recurrence periods were simulated through the stormwater management model (SWMM) and the geographic information system (GIS).The results show that the total rainfall,surface water storage,surface runoff,and runoff coefficient all increase with the recurrence period.There are positive correlations of rainfall intensity with the depth,time,and area of node waterlogging,area of the high waterlogging risk region,and the maximum depth and time of full flow in pipes.Node overflow mainly occurs in low-lying areas and regions with large catchments,dense populations,or large impervious areas.GIS and SWMM can be used to visually simulate the urban storm runoff and assess the drainage capacity of the pipe network and the urban waterlogging risk under different recurrence periods.The results of this research can provide a reference for the maintenance of urban pipe networks,the prevention and control of waterlogging disasters,and the construction of sponge cities.…”

mmWave radar based robust sign language recognition for the smart museum
Published 2023-08-01“…A smart museum is a new form of a museum, which uses devices or technologies including the Internet of things (IoT) and artificial intelligence (AI) to build the information interaction channels between people, things, and space.Sign language recognition not only assists the visitors who have hearing or speech impairment to visit the museum without barriers but also helps study the visitors’ natural gesture interaction.However, the methods based on cameras and wearable devices mayhave issues like privacy or usability when applied to museum spaces.Therefore, a robust sign language recognition method based on millimeter-wave radar was proposed.Different features of distance and velocity changes relative to the radar device were firstly extracted in this method, then a physical data enhancement method was adopted to expand the training data.Finally, a ResNet based on the pre-processed distance time features and Doppler time features was designed to further remove the environment-related information and perform feature fusion for classification.Experimental results show that this method can effectively recognize sign language and achieve an averaged recognition accuracy of over 90% when the testing environment and the user's location change, providing a new method for smart museum wireless sign language and gesture recognition.…”
