Based on the fuzzy propositional logic FLCOM and fuzzy set FSCOM, we research the formal denotation, inference and computation of fuzzy knowledge. We extend the fuzzy and-or graph, turn the propositional formulas as state nodes, express the logical rules as the search space, construct and-or graph of the fuzzy propositional formula. We modify heuristic function on the basis of the traditional and-or graph search algorithm, and give out a method to process negation information in the process of reasoning, transforming the fuzzy knowledge reasoning into the state space searching problem, and using the state space searching to solve the problem of fuzzy knowledge reasoning.

Characteristic parameters mining of unknown protocol bitstreams and parameters optimizing of clustering algorithm are the foundations of unknown protocol bitstreams analyzing. The parameters such as the bit frequency, runs and bit frequency within a block are defined according to the frequency of zero and one, frequency of sequential zero and one, bit frequency within a block. As the parameter of bit frequency within a block is sensitive to the block length, an optimal block length selection algorithm is proposed based on the principle of variance. In order to select effective initial clustering centers for division clustering algorithms such as the k-means algorithm, an initial clustering centers selection algorithm is proposed based on the peak value of sample density for each dimension. In order to select the optimal clustering number, a function of clustering quality evaluation is given by the sample density in cluster and cluster density. Taking the bitstreams of HTTP, DNS, ICMP, TELNET and UDP datasets as the unknown protocols bitstreams, the experimental results not only verified the effectiveness of the proposed algorithms but also point out the necessity of mining more effective parameters.

Many algorithms have been developed for image classification and support vector machine (SVM) is a kind of supervised classification that has been widely used recently. However, the accuracy of a SVM classifier heavily depends on the selection of a right kernel model and appropriate parameter. In this paper, a comparative analysis of the impact of four kernels (linear kernel, polynomial kernel, radial basis function kernel and sigmoid kernel) on the accuracy of SVM classifiers is conducted. Moreover, the Particle Swarm Optimization (PSO) is used to search for the optimum parameters for each kernel function in order to improve the classification accuracy of SVM classifiers. Our experiments for optimizing the kernel function parameters and assessing the robustness of SVM classifiers were carried out with classifications of QuickBird-2 images over Wuhan, China for monitoring urban land cover/land use information. The experimental results indicate that the polynomial kernel outperforms the other kernels in classifying high resolution remote sensing image. The sigmoid kernel performs worse than any other kernels. Our findings also suggest that selected parameter by PSO will improve the classification accuracy, especially for radial basis function kernel.

The scalable and efficient multi-class classification algorithm is now a well-known hard problem. Traditional methods of computer vision and machine learning cannot match human performance on images classification tasks. This paper proposes a novel semi-supervised classifier called Spatial Pyramid Deep Neural Networks (SPDNN). SPDNN utilizes a new deep architecture to integrate the ability of neural networks and spatial pyramid model because deep neural networks do not considerable the spatial information. Feature fusion has been more and more important for image and video retrieval, indexing and annotation because of the lack of single feature. We use multiple feature fusion over any single feature instead of pixels of images. The features include color feature, shape feature and texture feature. The performance of experiment shows that the algorithm improved the state-of-the-art image classification.

Energy saving is an hot topic recently as the energy crisis is more and more serious. Among the energy consumer of the world, building is often ignored by many people. Nowadays many researchers noticed that research on the energy saving of building is meaningful, especially the research on the energy saving of air-conditioning. As the energy consuming of air-conditioning is very significant. Traditional control method of air-conditioning is based on PID. In the paper, fussy control is introduced and applied in the air-conditioning control, the result shows that response speed and accuracy of fussy controller are significantly better than PID controller.

The vehicle state is of significant to examine and control vehicle performance. But some vehicle states such as vehicle velocity and side slip angle which are vital to active safety application of vehicle can not be measured directly and must be estimated instead. In this paper, a Cubature Kalman Filter (CKF) based algorithm for estimation vehicle velocity, yaw rate and side slip angle using steering wheel angle, longitudinal acceleration and lateral sensors is proposed. The estimator is designed based on a three-degree-of-freedom (3DOF) vehicle model. Effectiveness of the estimation is examined by comparing the outputs of the estimator with the responses of the vehicle model in CarSim under double lane change and slalom conditions.

The effect of 3-S-isothiuronium propyl sulfonate (UPS) upon the microholes filling by Cu electrodeposition was investigated by cross-sectional images using optical microscopy. The bottom-up filling of the electroplating bath was achieved with an addition of UPS. The electrochemical study indicated that the polarisation on the cathode was decreased with an addition of UPS. Furthermore, X-ray diffraction analyses showed the crystallography and the peak intensity ratio I(111)/I(200) of plated Cu film were decreased with addition of UPS. The results present UPS as an accelerator which is beneficial for microholes filling for high density interconnections printed circuit board.
