This paper proposes a mixed-integer quadratic programming (MIQP) model for optimal day-ahead distribution networks dispatch considering Wind Generators (WGs) and topology reconfiguration. Firstly, linearized current injection model is introduced for generators by a series of approximations. Then the day-ahead Switching Operations (SOs) of reconfiguration could be calculated in a linear form based...
Due to the low weight of monocular camera, monocular Simultaneous Localization and Mapping (SLAM) is an area of popular research and promotes countless applications of micro Unmanned Aerial Vehicles (UAVs), especially in some GPS-denied indoor environments. Nevertheless, the motion of UAVs is often faster and more complex than that of ground-based robots. It would also lead to error accumulation if...
In this paper, it presents a control strategy to trajectory tracking of multiple quadrotors while maintaining the desired formation. From the mathematical model of quadrotor, we can get that the controls of quadrotor in height and yaw direction are independent. Therefore, we can adopt different control strategies for the horizontal and height direction. We present a synchronization approach to trajectory...
The performance of a 4-station Multi-Terminal MMC HVDC system (MTDC-MMC-HVDC) is predicted by numerical integration of 57 first order Ordinary Differential Equations (ODEs). Wind power oscillation is also considered in this model. Because larger step-size can be used in the numerical integration of ODEs, to simulate a same size MTDC-MMC-HVDC system, the computations speed of our model increases over...
Learning the scene correlation of uncalibrated static cameras is in increasing demand for intelligent surveillance system, such as making a inference of topology, or allocating computation resources for video retrieval in multirobot system. However, many existing approaches learn the scene correlation among camera views by camera calibration or tracking targets across cameras. They seldom learn the...
It is a significant problem to learn the scene correlation of uncalibrated static cameras, which can be applied for intelligent surveillance systems with a large scale camera network. Some existing approaches learn the scene correlation among camera views by tracking targets across cameras. They seldom analyze the scene correlation among cameras with appearance modeling for moving targets. In this...
Static and dynamic simulation of effect of carbon source and hydraulic retention time (HRT) on removal performance of nitrogen and phosphorous were carried out by using activated sludge model software Biowin3 for typical anaerobic-anoxic-aerobic (A2/O) process in municipal wastewater treatment plant. The static simulation results showed that increasing C/N and C/P could improve obviously removal performance...
