Abstract.A novel version of the edge-Szeged index is proposed in parallel to the revised (vertex) Szeged index, and some properties, especially lower and upper bounds are established for this molecular descriptor. (doi: 10.5562/cca1889)
In order to improve the control accuracy and response speed of the intelligent vehicle steering system, a DC-motor controlled steering system using an IPC (Industrial personal computer) is designed. The hardware of the system is developed by analyzing the dynamic steering model. A new control method of Fuzzy-PID controller with RSDA (Rough Set Data Analysis) is proposed. Experimental results using the proposed control strategy show better performance and robust properties than the ordinary Fuzzy-PID.
Aiming at the problem of poor adaptability to environment when using a single sensor to detect road-edge, this paper proposed a road-edge detection method based on perception dominance. Firstly, the confidence model of 2D laser radar and vision sensor was established, and then the Dempster-Shafer Theory was used to fuse the detection results of 2D laser radar and vision sensor. Finally, the effectiveness of the method in harsh environment was verified by experiments.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
