Abstract: The contribution of various features for image recognition is different. In order to comprehensively and complementarily express the contents of liver CT image, a method of multiple features fusion based on PCA (Principal Component Analysis) is proposed in this paper. First, the features of each medical image include color, texture and shape are extracted, which constitute a feature vector that can represent the image. Then, for the wide gap of the value among the features, the features are standardized. Finally, the method of PCA is used to fuse the standardized features which can reduce the dimension and eliminate the redundant information among the features. The results through the recognition based on SVM (Support Vector Machine) proves that the fused features can express the contents of the liver CT image better and a higher recognition rate can be got in the image recognition.

Abstract: To relieve traffic overhead induced by active probing based methods, a new fault detection method, whose key is to divide the detection process into multiple stages, is proposed in this paper. During each stage, only a small region of the network is detected by using a small set of probes. Meanwhile, it also ensures that the entire network can be covered after multiple detection stages. This method can guarantee that the traffic used by probes during each detection stage is small sufficiently so that the network can operate without severe disturbance from probes. Several simulation results verify the effectiveness of the proposed method.

This paper proposes a parametric design ideas, the use of Auto-CAD's VBA language and Dialog control language (DCL), which can input the various parameters for gear class by dialogue box, and can calculate the value of gear class, proofreading and draw each parameter gears different structure design, that can output fully automated computer-aided design system. Experimental indicate the system can complete gear design parameters, should be widely applied.

Abstract: For TV model, repair algorithm only along the gradient perpendicular to the direction of diffusion that will cause staircase effect, iterative low efficiency and generate false edge of the shortcomings. The article improved K and P parameters of manufacturing image restoration algorithm. The algorithm contains both isotropic and anisotropic diffusion, taking regional frequency difference realized in different areas using different iterative equation. The experimental results show that the algorithm is compared with the TV model algorithm has the same restorative effects, avoid the staircase effect and better than the TV model repair speed.

Abstract: The innovation of computer software and hardware technology has brought the power to support strong for the numerical simulation technology, and computer three-dimensional simulation has been applied to various engineering fields. Engineering safety early warning system is a hot problem of the computer simulation, in which using the ANSYS computer software can calculate the stress numerical in engineering to carry out stress analysis, which could realize the function of engineering safety early warning. In this paper, the mining slope stress calculation and prediction as an example, we carry out calculate the stress of mine slope, and as can be seen from the calculations, mine stress does not reach the ultimate safety value, the maximum stress of mine Y direction reached is 5.81Mpa, exceeding the limit value of 5.60Mpa; Z direction compressive stress is reached 3.78Mpa, more than the stress limit 3.56MPa. After the stress limit, mine is prone to landslide hazard, so this paper markers the dangerous positions through the ANSYS software, which can be the successful implementation of the mine slope stress detection and early warning.

Abstract: In this paper, we use the software of ANSYS and MATLAB to do research on early computer warning system. ANSYS can check the intensity of early warning system, and MATLAB can realize the visual function of warning system. In this paper we established the process model of ANSYS intensity checking, and designed the calculation process of order flow. We use the disaster warning when opencast mining to underground mining as an example to verify the model and the algorithm. Through the calculation we get the correlation table between calculated and measured value. Finally we get the biggest stress nephogram of chamber center by using ANSYS software, and through the MATLAB software we realized visualization of surrounding rock stress. It provides the theoretical reference for the research on computer warning system in mining process. With the development of computer hardware and software technology, computer information early warning system begins to appear in many engineering fields. This system can carry on security issues of real-time detection and warning in the process of project implementation, and through the visualization software to display this information.
