S-system is a commonly used model for dynamic biological system. However, due to technical limitations, biological reaction networks are often only partially observable, which indicates that not all individuals incorporated in the model can be measured directly. Given a limited amount and quality of experimental data, it cannot be assured that the model structure and parameters can be estimated unambiguously...
This paper mainly implements human following function for home service robot, May, developed in our laboratory. In order to follow the operator accurately, visual tracking is composed by Tracing-Learning-Detection (TLD) and Kinect skeleton, where TLD plays the role as re-detecting the situation that operator is occluded or disappeared, and Kinect skeleton is adopted to track all other situations while...
This paper mainly confers the development of tracking controller design for wheeled mobile robots with plant uncertainties and external disturbances. This paper proposes a unified and systematic procedure to design adaptive fuzzy tracking controllers for such system. At first an adaptive fuzzy tracking controller (AFTC) is designed for the nonholonomic constrained wheeled mobile robots without considering...
In leaves of A. thaliana, there exists an intricate network of epidermal surface layer cells responsible for anatomical stability and vigor of flexibility to the entire leaf. Rho GTPases direct this organization of cell polarity, but full understanding of the underlying mechanisms demands further inquiry. We conduct two experiments: (1) a novel procedure is proposed that could be used in other life...
In this paper, a novel evolutionary learning algorithm is proposed by hybridizing the clonal selection algorithm (CLONALG) and the artificial bee colony algorithm (ABC). The algorithm is thus called HCABC to enhance the CLONALG performance. This algorithm presents a new idea to optimize the parameter and structure of the PID-like fuzzy controller simultaneously. The ABC algorithm has been proven to...
A generalization of multiresolution analysis (MRA) to arbitrary affine frames, and the constructions of affine frames based on MRAs are considered and characterized. The authors define a frame multiresolution analysis (FMRA) and provide a necessary and sufficient condition for constructing frames of translates. Conditions for constructing FMRAs and associated frames are derived. The results are part...
