As the knowledge in the fault diagnosis of civil aircraft is dynamic and uncertain, a method based on the Adaptive Fuzzy Petri Net(APFN) is proposed to solve the problem. AFPN not only takes the descriptive advantages of fuzzy Petri net, but also has learning ability like neural network. By this mean, firstly set up a fuzzy Petri net using the fuzzy production rule. Then the parameters of the fuzzy Petri net are trained by BP learning algorithm. At last, when the weights of the fuzzy Petri net are fixed, the fault origin can be found through the fault inference. At the end of the paper, an experiment is designed to demonstrate that the approach is feasible and effective in fuzzy reasoning.

This paper proposed a wholly new offset approximation method. Based on the improvement of the best rational Chebyshev approximation theory, approximating the offset curve along the offset direction is investigated, and the approximation error is also measured along the offset direction, which could reflect the real approximation effect. Experiments show that the proposed method has advantage of low complexity, high precision, and global error control.

Braking deviation system is an important piece of automotive operating equipment, targeting on the problems of complex fault mechanisms of automotive hydraulic braking system and uncertainty between fault type and fault symptoms, the method of Bayesian network fault diagnosis in baking deviation system has been raised. In the learning process of Bayesian network structure, this algorithm adopts statistical strategy for the rule library provided by many experts, discard rules with relatively weak casual relationship, and retain rules with stronger causal relationship, thereby set up the fault diagnosis hierarchical structure model in braking deviation system based on Bayesian network. Experimental data analysis shows that the Bayesian network fault diagnosis model has higher accuracy than fuzzy logic diagnosis method, effectively solving the uncertainties in fault diagnosis.

In this paper, we study the scattering of time harm-onic electromagnetic waves by a homogeneous layer above a perfectly conducting surface in the case of TM polarization. We first, propose a variational formulation, and establish its equivalence to the boundary value problem. Then we prove, via Lax-Milgram theorem, the well-posedness of this problem for small wave number, and obtain a stability estimation about the solution, which show explicitly the dependence on wave number and the maximum surface elevation. Finally, we consider the case of conducting layer, and show the problem is still uniquely solvable based on the results of dielectric case.

To get sufficient environmental information for a teleoperated unmanned vehicle, a matched image with wide field and high quality image is necessary. Image matching is a key point in image mosaic. And the vast amounts of data and complex calculations make it bottlenecked to get a high speed on mosaicing images. Considering the requirements of real-time image mosaic, a self-adaptive image matching method, considering the priori information on the spatial relationship between images, is proposed in this paper. The overlapping region is used as one of the constraint to reduce the search range during the image matching process. And using the General Purpose Graphic Process Unit (GPGPU) to accelerate complex computations, is becoming a research focus. In this paper, the algorithm of image matching is parallelized based on Compute Unified Device Architecture (CUDA), which is a platform of GPGPU programming. Experiment results show that, compared with the serial scheme on CPU, the efficiency of image mosaicing, implemented with the parallel scheme on Graphic Process Unit (GPU), is improved more than 30 times, with 12.8 frames per second.

For the problem of affective recognition from pulse signal, a new feature selection method which combines correlation analysis with max-min ant colony algorithm is proposed in this paper, and stable feature subsets with good performance are found to construct affective recognition model. Firstly, sequential backward selection (SBS) is used for sorting of the original features. Secondly, the linear correlation coefficient is adopted to compute the correlation degrees between the features and features with high correlation degrees are removed through the result of sorting. Finally, max-min ant colony algorithm is used for feature selection, which searches for an optimal subset based on the compact feature subset, and six emotions (happiness, surprise, disgust, grief, anger and fear) are recognized by means of Fisher classifier. The experimental results show that the method can construct effective affective recognition model through stable and effective feature subsets chosen from original features.

In order to achieve the intelligent water meter reading, a water meter ID identifying and reading system based on RFID technology has been designed. Because most of water meters are made by foundry iron, the transmit signals will be interfered with the iron if we use ordinary UHF tags. To solve this problem, the system uses anti-metal UHF tags as the data transmitter and hand-held data reader as the Data receiver. Furthermore, ISO18000-6C is selected as the Radio-Frequency Identity protocol. As a result, the communication distance can reach more than 1 meter in the proposed system, which provides a solution for intelligent water meter reading and data saving in database.
