This paper investigates the maintenance scheduling problem in a flow line system consisting of two series machines with a finite buffer in between. The machines deteriorate with age and have multiple deteriorating quality states represented by multiple decreasing yield levels. The maintenance problem of both machines is modeled as semi-Markov decision processes. A heuristically accelerated multi-agent reinforcement learning algorithm with a feature of incorporating heuristic function for action selection is developed to produce a reasonable maintenance scheduling. A comparison with a Ε-greedy search based exploration algorithm, a simulated annealing search based exploration algorithm, a tabu search based exploration algorithm and a neighborhood search based exploration algorithm in reinforcement learning is presented. The results indicate that the proposed heuristically accelerated multi-agent reinforcement learning algorithm is competitive and has a certain advantage for larger problems.

An Echo State Network (ESN) based predictive control method for aircraft system is proposed to increase the flight quality. Aero craft is a nonlinear and time-varying system and its controllers are usually designed by trajectory linearization method. Furthermore, the predictive controller is designed to adjust the current controlled variables by the trend of output to improve the quick responsiveness and traceability. Then, the stability of the system is proved by Lyapunov function. Finally, the numerical simulation results of step-response and attitude tracking illustrate the robustness and effect of the method.

Hierarchy task network (HTN) planning, as one of AI planning approaches, has been widely used in the emergency decision making for action planning in recent years, in which domain knowledge plays an important role. The special and complicated characteristics of emergency domain knowledge make it difficult to model, hindering the application of HTN planning to emergency action plan development. Though ontology modeling can get over the difficulty, existing ontology models for the emergency domain knowledge are either incomplete or not applicable for HTN planning. This paper aims at constructing emergency domain knowledge ontology applicable for HTN planner SHOP2 which can effectively support the emergency action plan development. An approach of translating an emergency domain knowledge model into a SHOP2 domain is also discussed in the paper. Finally an implementation of our work is roughly introduced.

In order to solve the problem of image degradation caused by dust environments, an image degradation model considering multiple scattering factors caused by dust was first established using the first-order multiple scattering method. Then, a dark channel prior principle was applied to present an image restoration algorithm based on the image degradation model. Finally, a particle swarm optimization algorithm was applied to optimize the atmospheric light and the exposure parameters. This optimization algorithm was established according to the criterion of the image evaluation based on kirsch operator with dual threshold. By using the method an optimistic result of image restoration was obtained. The experimental results have shown that the method not only enhanced luminance and contrast, but also discovered more detail edges information. The method provided a foundation for target recognition in the dust environments. © 2010 IEEE.

image mosaic technique based on interest points feature matching

引用

Guangdianzi Jiguang/Journal of Optoelectronics Laser 2006年第6期17卷 733-737页

作者： Wu, Jian-Ning Guo, Bao-Long Feng, Zong-Zhe Institute of Intelligent Control and Image Engineering Xidian University Xi'an 710071 China

An automatic image mosaic technique based on interest points feature matching (IPFM) was proposed. Firstly the combined corner and edge detector is used to gain the interest points, and a kind of bidirectional greatest correlative coefficient match law is used to extract the initial feature points pair, then the false feature points pair is rejected by space coordinate distance criterion, finally the correct match feature points pair is used to realize image stitching;In addition, the field value concept is introduced in the image fusion technology to solve the smooth transition problem through overlap region. The experimental results indicated that this method can fast and accurately extract the corresponding feature points between two images and reduce the probability greatly which matches by mistake. Under the existing slight rotator situation, this method still could effectively realize the image smoothly stitching.

Guangdianzi Jiguang/Journal of Optoelectronics Laser 2007年第6期18卷 738-740页

作者： Yang, Zhan-Long Guo, Bao-Long Institute of Intelligent Control and Image Engineering Xidian University Xi'an 710071 China

An automatic image mosaic method based on invariant moments of interest points was proposed. Firstly the Harris corner detector is used to gain the interest points, and the moment invariants to translation, rotation and scale defined on the interest point neighborhood are computed. Then by comparing the Euclidean distance of these invariant moments, the initial feature points pairs are extracted, and the spurious feature points pairs are by eliminated by geometric transform model. Finally image stitching with the correct mapping model is realized. Experimental results demonstrate the proposed algorithm is robust to translation, rotation and slight scaling.
