Health grading evaluation is an important technology in health management. Taking the advantage of Bayesian networks in dealing with the issue of uncertainty, this paper puts forward the dynamic Bayesian network model based on the three-state dividing of system which is according to circuits' fault characteristics of hierarchy, correlation and uncertainty. Component-level health quantitative assessment...
In multiple AUVs cooperative navigation system, a small amount of leader AUVs with high precision navigation sensors lead a large amount of follower AUVs with low accuracy navigation sensors to complete the task, which has important engineering application value. Improving follower AUV navigation and positioning accuracy is cooperative navigation key issues. In view of the water communication data...
In order to meet the needs of real-time communication and control in Autonomous Underwater Vehicle (AUV), a communication network of AUV based on CAN bus technology is designed. The real-time performance of the messages based on the AUV is analyzed and evaluated, and then the CAN bus system is analyzed through stimulation software CANoe and hardware-in-the-loop simulation. The communication mode has...
As a major part of the Dianchi Lake, the Caohai Lake is in a serious eutrophication situation, which is imminent for pollution treatment. An improved floating bed, which called combined packing with emergent aquatic plants canna indica, submerged aquatic plants Hydrilla verticillata and aeration device, was used to purify the water taken from the Caohai Lake. Compared with the traditional floating...
