摘要：
In order to improve the quality of peak characteristics extraction in chromatographic data, an automatic peak fitting method based on wavelet ridges and morphology (WMPF) was proposed. In handling overlapping peaks and weak peaks, WMPF gave solution to deal with the shortcomings of existing peak detection methods. The ridge line of the signal was obtained by wavelet transform of the original chromatogram signal, and the signal was divided into peak areas and non-peak areas. Then, we processed morphological operations with an adaptive window, and combined Gaussian fitting with wavelet ridge information. Finally, the peak characteristics of the signal were extracted. Through the analysis of high-density lipoprotein electrophoretogram data, it was confirmed that the proposed method was effective for baseline separation, noise elimination, peak detection and overlapping peak recognition.

摘要：
In this paper, we present a bio-inspired model for detecting edges based on mathematic analysis of artificial retina response. And then mathematical analysis as well as computational design methods on the proposed retina model are dealt with. The characteristics of our model is that it just concerns four types of cells rather than traditional ones with five types of cells. Experimental results show that the proposed model based on retina neural mechanism for edge detection is efficient.

摘要：
In view of the characteristics of the physical code Nestor the focus is on the correctness of calculation for which the test adequacy criterion has been established. This is based on structural coverage and the input domain. According to such test adequacy criterion, testing strategies have been applied on the entire testing process. They consist of unit static, unit dynamic, integration, system and regression test strategy. Each strategy is composed of test target, test range, technology and method, entry criterion, completion criterion, test focus and priority. After compared with 11 basic benchmarks from nuclear power plants and calculation result of benchmark programs, the ELEMENT program result is correct and credible; the relative error of result is less than three percent. The ELEMENT testing is adequacy. Its test cases covers fuel grid element types, fuel types, non-combustible grid element types, and control rod computational models. Furthermore, it puts forward a research direction in the future.

摘要：
Aimed at the characteristics of strong nonlinearity, uncertainty, time-variance and serious interconnection etc for AC electric arc-furnace (EAF). A new control method is put forward, in which fuzzy-neural network is applied. Mamdani fuzzy model is adopted in the control system, its structure has four layers. According to the gradient descent strategy, the variable learning speed algorithm of the off-line is used to seek for the better parameters of membership function and the weights of the links between layer III and layer W, the invariable learning speed algorithm of the on-line is used to search for their optimization parameters. The unbalanced technical question of the AC EAF's three phase current is solved by fuzzy-neural control method. At the same time, the hard structure and soft structure of system are introduced in this paper. It has better robustness and real-time ability in running system.

In view of the current situation of the less embedded Linux image acquisition application based on V4L2(Video for Linux Two), embedded image acquisition system based on V4L2 is designed. S3C6410 is adopted as hardware development platform and Linux as software platform. After loading the driver of CMOS camera OV9650 and other relative drivers, image acquisition applications on the basis of V4L2 is compiled, adopting double frame buffer to reduce CPU utilization rate to accomplish acquisition and preview image. With the size of 400x480 and the frame rate of 15 frames per second, the picture collected shows clearly and it has good quality. The experiment result indicates that the system has good scalability, and it offers a new idea for embedded hand-held devices.
摘要：
The roundness and surface roughness are important quality performances for machined round parts. In order to get the best quality performance by less experiment search for optimum parameters, an orthogonal array was used for the experimental design, optimal machining parameters were determined by the grey relational grade obtained from the grey relational analysis, and the main machining parameters that affect the machining performance can be found by the difference between the maximum and minimum value of the grey relational grade of the machining parameters. Experimental results have shown that the roundness and surface roughness of machined round parts can be improved effectively by the proposed approach.
摘要：
Based on the compressive sensing theory (CS), various compressive imaging (CI) systems have been developed. Meanwhile, image fusion methods that directly perform on the measurements from multiple CI sensors are also investigated in literatures. In this paper, we presented a multi-focus image fusion method in compressive sensing domain. The main contribution is to introduce a novel clarity level of the random CI measurements without prior geometric information. The CI measurements are sparsely represented with DCT bases which are also projected into the CS domain. Then the sparse coefficients responding to DCT bases are used to guide the fusion of CI measurements of CI sensors. Finally, the fused images are obtained with CS recovery algorithm based on the block compressive sensing (BCS) theory. The simulation results validate the proposed method.

Digital instrument control platform;Information security;Vulnerability analysis;Security loophole
摘要：
From the general industrial control system to the nuclear power plant control platform, the threat of information security has its own particularity more than continuity.The original dedicated system in general industrial area is gradually replaced by many common protocol, software and equipment. As a result, the security vulnerabilities are more likely to be used illegally. For a specific nuclear power plant digital control platform-NASPIC, the vulnerability analysis of platform is performed. Mainly two aspects of technology and management are to be carried out. For technical aspects, four categories problems-unauthorized execution, unauthorized write, unauthorized reading and reject service-are analyzed. Management is mainly about the lack of management strategy and strategy vulnerability. By analyzing the fragility of the instrument control platform, the key equipments, key channels and key modules are proposed. The qualitative and quantitative rules are deduced for evaluation of NASPIC information security.

摘要：
Based on analysing the factors that cause torque ripple and analysing the nonzero demagnetism/in magnetism component in stator current for the typical direct torque control system of the permanent magnet synchronous motor, this paper presents a novel control system which directly controls the magnetizing component of the stator current with two-level bang-bang controller.The improvement eliminated the component which in the stator current did not hope, enhanced the exchange transmission system efficiency. It is simple and easy to implement. The simulation results indicate static and dynamic performance of the new system is improved and torque ripple is decreased, simultaneously still retains the better control performance and higher efficiency than the typical direct torque control system.
