In this paper, taking Yangshuo County, which is frequently affected by mountain floods and Lijiang River transit floods together, as an example, we utilize the high-precision flood data generated by the coupled hydrological-hydrodynamic models in a machine learning sample library and construct the maximum inundation water depth prediction model (KNN-Depth) and the maximum inundation flow rate prediction model (KNN-Speed) based on the machine learning K-nearest-neighbor algorithm (KNN) to predict the maximum inundation water depth and maximum inundation flow rate. The prediction performance of the models has been tested and examined with 17 data sets of historical floods, in which a total of six flood risk classes have been classified to carry out flood risk prediction in the study area by considering the two indicators of maximum inundation water depth and maximum inundation flow rate. The results show that: 1) The maximum inundation water depth predicted by KNN-Depth is close to the simulation results of the maximum inundation water depth of the hydrodynamic model, and the mean values of the Coefficients of Determination (R2), Root Mean Square Error (RMSE), and Mean Absolute Error (MAE) indexes of the 17 floods are 0.988, 0.127m, and 0.060m, respectively;2) The maximum inundation flow velocity generated by KNN-Speed model is similar to the simulation results of the maximum inundation flow velocity of the hydrodynamic model, and the mean values of R2, RMSE and MAE indicators of the 17 floods are 0.968, 0.051m/s and 0.020m/s, respectively;3) The running time of KNN-Depth and KNN-Speed models is 2s and 10s, respectively for the prediction;4) The research indicates that the flood risk in Yangshuo County within 500m of the banks of the main rivers during a large flood is level 6 in general, and the flood risk in the new and old urban areas is up to level 5. © 2024 IEEE.

Transparent conductive films (TCFs) are widely used as electrodes in flexible optoelectronic devices, which have very strong potential applications in a lot of fields. Currently, one of the most intensively studied subject in this community is developing transparent organic buffer layer with both low thermal expansion coefficient and strong interfacial bonding energy with TCFs, so as to enhance their resistibility against thermal expansion during device working. This is particularly important for the ceramic type TCFs, such as indium tin oxide (ITO), because their thermal expansion coefficients are almost two orders of magnitude lower than that of flexible organic substrates. In this work, we have successfully developed a new highly transparent SiO2-PMMA buffer layer with glass transition temperature of 119.6 ℃. Thermal shock tests reveal that a 100 nm thick ITO film grown on this SiO2-PMMA buffer layer can tolerate 10 cycles of temperature shock between -55 ℃ and 120 ℃. In addition, the interfacial adhesion between organic substrate and ITO film after thermal shock was greatly enhanced as well by introducing SiO2-PMMA buffer layer. Our work presents the possible for ITO films to achieve the good thermal shock resistance and robust adhesion to organic substrates simultaneously, and is expected to be widely used in flexible optoelectronic devices. © 2024 SPIE.

Twin ducted fan UAV is a novel aircraft with redundant control effectors and the interactions between actuators and control allocators can not be ignored. In this paper, dynamic control allocation is used to deal with the control allocation problem of Twin ducted fan UAV. First, the actuator rate is penalized in the optimization function of the control allocation based on the quadratic programming method. Second, a post-compensation method is applied to compensate for command increment attenuation. The simulation results show that the dynamic control allocation method with actuator dynamic compensation can prevent the high bandwidth actuator from saturating in advance, and the virtual control command is effectively allocated to actuators with different bandwidths. © 2022, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Nowadays, human body motion detection is closely related to national defense security, urban public security, and people's daily lives. In this paper, the pyroelectric sensor is utilized to detect the different electrical signals generated by the human body when making various movements. By designing the pyroelectric infrared sensor unit, signal processing unit, microcontroller data acquisition unit, and Labview host computer display unit, the electrical signals from the infrared sensor were collected. Through experiments capturing the pyroelectric infrared signals of human stepping and jumps, an analysis and comparison of the two types of motion signals were conducted, successfully distinguishing between stepping and jumping actions. © 2024 IEEE.

In order to solve the challenges of high-precision maps based on lidar 3D point clouds, which are expensive on-vehicle sensors and high computing power requirements, the academic community has proposed a cognitive map solution with low cost, small amount of data, and moderate positioning accuracy. The current cognitive map mainly relies on the geometric relationship between road signs and lane lines to complete vehicle positioning, and the local positioning accuracy needs to be further improved. This paper proposes a real-time vectorized map modeling solution, using a vectorized map instead of a discrete point map to support a vehicle positioning solution based on road geometry, thereby improving the local positioning accuracy of the vehicle. At the same time, in order to solve the problem of vehicle global positioning, this paper adopts a location recognition algorithm based on the perspective of the vehicle to complete the global location estimation of the vehicle on a large scale only by relying on the vision, so as to serve the navigation function. © 2022 ACM.
