The trajectory planning of Unmanned Aerial Vehicle (UAV) and Aerial Robots generally refers to a series of optimization problems. This paper presents a method of trajectory planning and design for UAV based on the A* algorithm. Using grids to process the trajectory path planning of UAV under the environment with presence of obstacles, and then search the shortest path from the initial point to the...
Trajectory planning of robots is not only an important research field of robotics, but also an challenging combination of artificial intelligence and robotics. Trajectory planning is a key technology of Unmanned Aerial Vehicle (UAV). It is also a prerequisite for autonomous navigation of UAV. Under the static environment distributing of obstacles, seeking a shortest path from the starting point to...
One of the current challenges in the development of robot navigation systems is making them capable of intelligent and suitable responses to the complex and changing environments. The navigation of the robot's behavior becomes very challenging when it is under complex and dynamic environments. Autonomous navigation systems for mobile robots have been well developed for a wide range of planar ground-based...
This paper presents a method of trajectory planning and design for Unmanned Aerial Vehicle (UAV) based on the A∗ algorithm. Using grids to process the trajectory path planning of UAV under the environment with presence of obstacles, and then find the shortest path from the initial point to the target point based on rasterized environment using A∗ algorithm. The simulation of trajectory planning is...
Social network has played a more and more important role in recommender system as users are strongly influenced by their friends. But the friend lists of a user are always hidden for privacy concern. Even her friend lists are accessible, there still exist many potential friends who have similar interest with her but she doesn't know. How to predict the friendship she knows and does not know when the...
Inter-subject correspondence is an important aspect of multi-subject fMRI studies. Recently, a new approach, called hyperalignment, has shown very promising results in fMRI functional alignment. Hyperalignment is based on Procrustean rotations and is connected, mathematically, to canonical correlation analysis. We review the core details of each approach, relate them through an SVD analysis, and indicate...
The training in the surgical practice is of paramount importance to prepare the residents in performing surgical procedures on human subject and to provide exercise on new techniques for experienced surgeons. Usually, these trainings are carried out on live animals or in virtual environments and dry boxes; the complexity of the exercises is identical in both of the case, but the pressure in operating...
With the rapid development of e-commerce and the growth of Internet business market, security risks in e-commerce become the obstacle which hinders consumers' online purchasing. This paper outlines several kinds of consumers' perceived security risks in e-commerce, and online consumers' assessment information with regard to each security risk are obtained by using well-designed questionnaire. The...
