Abstract: To simulate the service behavior of new-made concrete pipelines in a sewage environment, the corrosion of different mortars in three stages of abiotic neutralization, neutral, and acidophilic bacteria action was studied. ...

Abstract: Aiming at raising the efficiency of multidisciplinary optimization of UAV rotor aerodynamics and aeroacoustics, this paper established a low-order method of rotor aerodynamics and noise prediction based on lifting line ...
