In this study, the self-evolution problem of knowledgeable manufacturing systems is studied by taking an assembly workshop as an example. The rolling horizon procedure (RHP) is adopted to implement the self-evolution process of the workshop. The whole dynamic self-evolution process is decomposed into several static decision processes. At each decision point, a static decision sub-problem needs to be solved. A general mathematical model of these sub-problems is built, and a bi-level genetic algorithm (BiGA) is designed. Simulation results show that the model and algorithm are feasible and effective. By comparison, the system with self-evolution operations has a better production performance. © (2014) Trans Tech Publications, Switzerland.

Coordinated Adaptive control for Coordinated Path-following Surface Vessels with a Time-invariant Orbital Velocity

This article considers the problem of directing a family of fully actuated surface vessels to cooperatively follow a set of convex and closed orbits with a time-invariant reference orbital velocity and maintain attitude synchronization. A consensusbased adaptive control law under a bidirectional communication topology is proposed to estimate the reference orbital velocity so that the restriction that every vessel in the family must have access to the reference in the previous literature can be *** assumption of nonzero total linear speed of each vessel is removed by the use of potential function. Simulation results demonstrate the effectiveness of the proposed approach.

Pedestrian detection is a hot research topic in pattern recognition and computer vision. We combine MBBP（Multiscale Block Local Binary Patterns）feature and Histogram Intersection Kernel SVM and apply them to pedestrian detection. MBBP features, which make up for the lack of LBP（Local Binary Patterns） features in robustness, is a kind of effective texture description *** Intersection Kernel Support Vector Machine has the advantage of fast classification and high accuracy in object recognition. It can be used for further enhancing the system's real-time performance. The experiments show that the proposed approach has higher precision than the classical algorithm HOG+Linear SVM and the HOGBP Features Fusion tested on the established benchmarking datasets—INRIA.

K-means clustering has been extremely popular in scene image classification. However, due to the random selection of initial cluster centers, the algorithm cannot always provide the most optimal results. In this paper, we develop a density-based k-means clustering. First, we calculate the density and distance for each feature vector. Then choose those features with high density and large distance as initial cluster centers. The remaining steps are the same with k-means. In order to evaluate our proposed algorithm, we have conducted several experiments on twoscene image datasets: Fifteen Scene Categories dataset and UIUC Sports Event dataset. The results show that our proposed method has good repeatability. Compared with the traditional k-means clustering, it can achieve higher classification accuracy when applied in multiclass scene image classification.

There is a growing interest in subspace learning techniques for face recognition. This paper proposes a novel face recognition method based on MPCA with Gabor tensor representation. Although the Gabor face representation has achieved great success in face recognition, the excessive dimension of the data space often brings the algorithms into the curse of dimensionality dilemma. In this paper, we propose a 3rd-order Gabor tensor representation derived from a complete response set of 40 Gabor filters. Then MPCA(Multi-linear Principal Component Analysis) is applied to each Gabor tensor to extract three discriminative *** dimension reduction is done in such a way that most useful information is retained. The subspaces are finally integrated for classification. Experimental results on ORL database show promising results of the proposed method.

IEEE International Conference on Automation Science and engineering (CASE)

作者： Jun Li Xing Dai Huaxuan Liu MengChu Zhou Ministry of Education Key Laboratory of Measurement and Control of CSE (Complex Systems of Engineering) Southeast University Nanjing China Department of Electrical and Computer Engineering New Jersey Institute of Technology Newark NJ USA

As a well-known combinatorial optimization problem, multiple traveling salesman problem (MTSP) fails to characterize some application problems where cities may have different accessibility for some but not necessarily all salesmen. This work proposes a colored traveling salesman problem (CTSP) in which a city has one to multiple colors allowing any salesman with the same color to visit. It presents a decomposition approach that converts CTSP into a combination of several individual traveling salesman problems (TSPs) and one MTSP for an important class of CTSP. To solve the transformed one, this work proposes a modified greedy algorithm allowing multi-colored city assignment during city search and adopts the formerly presented simulated annealing genetic algorithm. A dual-bridge waterjet cutting example is utilized to compare the presented decomposition approach and direct one. The results show that the former can achieve a better solution than the latter if the cities of same color(s) are clumped.
