Smart City, whose main characteristics are intelligence and interconnection capability, has become an important goal of some cities’ development. This paper, based on urban three-dimensional geographic information characteristics, analyses 3D geographic information requirements in the Smart City construction and development process, proposes construction and management methods for 3D geographic information. Furthermore, this paper takes Shanghai Geographic Information Public Service Platform as an example, discusses 3D geographic information application in multiple fields, and proves that it is an effective ways to promote Intelligent City construction.

Modeling and control of marine vessels raised huge interests in recent years. Lots of articles provided many different mathematical modeling and dynamic control methods with advanced intelligent algorithms. In this paper we presented a 6 DOF dynamic model for a tanker vessel, investigated on its maneuverability and conducted numerical simulation experiments to show 6 DOF motion behavior of the vessel including position and orientation. And we discussed the turning ability of the vessel in simulation using a PID controller in the present of environmental waves.

In this study, passive dynamic control of a manipulator is designed and realized. According to the control strategy, the shift in the position and orientation of an end effector attributable to an external force is regarded as deformation of the robot. The Zener model, known as a standard linear solid model, is used to generate the deformable behavior, which describes the combination of plastic and elastic deformation. Based on the relation analysis between the Zener model and two other deformable models, two types of control methods are proposed in terms of the model’s expression. Physical simulations with a robotic arm are executed to validate the proposed control laws.

The last effect of any thrombosis is recanalization. The aim of this study was to investigate the possibility of thrombosed cerebral venous vessels recanalization and the determination of optimal control methods after thrombolytic therapy. A group of 106 patients with adiagnosis of cerebral venous thrombosis after MRI, MR-angiography, ultrasound duplex scanning and CT-angiography underwent dynamic control examinations after thrombolytic therapy. MR-angiography and ultrasound duplex scanning appeared to be satisfactory and effective control methods to disclose thrombosed cerebral venous vessel recanalization. In our study venous vessels were recanalized in 15 cases (14%). The majority of cases of recanalization were revealed in the acute period of thrombosis.

Flood Limited Water Level

t is important to reasonably raise the reservoir flood limited water level in order to increase the utilization of the rainwater resources. The methods to set the flood limited water level include the static control and the dynamic control. And the dynamic control methods include the multiple duration method and the dynamic control method. All those methods were summarized and analyzed in this paper, especially the dynamic control. The advantages of the multiple duration method and the dynamic control method for the flood were indicated respectively. Those two methods were contrastively analyzed from the design principles, the application conditions, the actual operation complexity and the risk control factors. Then the conclusion was obtained, that the dynamic control method will be more advantageous and popular than the multiple duration the in the future.
