A curve fitting method based on automatically extracting subsection points is proposed to fit the wheel tread profile accurately. Firstly, the subsection points are determined by segmenting discrete points of wheel tread profile based on given errors and threshold. Secondly, the segmentation interval is determined with the respective segment point as the center, and the least squares curve fitting...
Selfish behaviors significantly affect the overall performance of mobile ad hoc networks (MANETs). Reputation systems have been proved to be an efficient way to block such behaviors in MANETs. Several reputation models based on subjective logic have been proposed to improve the reputation mechanism, in which an uncertainty value is introduced for reputation computation when the local information is...
This paper describes the research of genetic algorithm (GA) based PID for autonomous underwater vehicle (AUV) motion control. A simulation of heading control application is considered using GA and improved GA based PID. The dynamic model of AUV is established. The design method of GA and improved GA based PID is introduced. The heading control design model is obtained by the AUV linearization model...
This paper focuses on the automatic registration and precise positioning of high-resolution satellite images and a vector map utilizing the RPC. First, the general RFM is introduced for high-resolution satellite images, and then the methods to compensate for systemic errors of these models are stated. Experiments with SPOT-5 images are analyzed and suggest the automatic registration of high-resolution...
