Database security is very important in an information system. Most database management systems (DBMS) use access control to protect database. But access control can't resist bypass threats. Database encryption can resist these threats well. Encrypting data can exist on different positions in a DBMS. This paper compares four database encryption schemes in DBMS and proposes six design criteria for database encryptions. According to these criteria, we implement a prototype in Postgre SQL compliance with the fourth scheme. Our design hasn't impact on other database functions and makes no changes on DBMS structure. So it is a good way to enhance database security especially existing DBMS. Finally, we compare performance of database between with encryption and without encryption. The downgrade of performance is little and tolerable.

By analysis of common boundary tracing algorithm in the binary image identification, this paper proposes a universal boundary tracing algorithm based on contour, which can judge the trend of contour according to the last boundary point. In search for the next boundary point, it only needs to judge 5 points on the candidate and then the next boundary point can be found. Thus the method reduces search times and the boundary tracking is greatly reduced. The algorithm is also effective for line segment whose contour is not closed by scanning the contour to get information. Experiments show that the algorithm is not only fast, but also accurate about the contour recognition. For the object which has complex images, algorithm can embody its superiority.

To realize the fast and accurate detection of the edges from the blurry images, the fast multi-level fuzzy edge detection (FMFED) algorithm is proposed. The FMFED algorithm first enhances the image contrast by means of the fast multi-level fuzzy enhancement (FMFE) algorithm using the simple transformation function based on two image thresholds. Second, the edges are extracted from the enhanced image by the two-stage edge detection operator which identifies the edge candidates based on the local characteristics of the image and then determines the true edge pixels using the edge detection operator based on the extreme of the gradient values. Experimental results demonstrate that the FMFED algorithm can extract the thin edges and remove the false edges from the image, which leads to its better performance than the Sobel operator, Canny operator, traditional fuzzy edge detection algorithm and other multi-level fuzzy edge detection algorithms.

The decision-based adaptive weighted mean filter is proposed to remove impulse noise from the highly corrupted image. The proposed filter first identifies the corrupted pixels using the soft decision-based noise detector and then removes the detected impulses using the adaptive weighted mean filter while keeping the uncorrupted pixels unaltered. Extensive simulations indicate that the proposed filter significantly outperforms a number of existing decision-based filters in that it can remove impulse noise from the corrupted image effectively while preserving the details in the image very well.

College physics experiment teaching is different from the general theoretical knowledge teaching, which emphasizes students’ practical ability and logical thinking ability in experimental design. The traditional teaching approach still has shortcomings in the cultivation of students’ interest in experiment, and meanwhile, it is not conductive for the improvement of students’ learning interest in experimental course. The hierarchical teaching approach proposed achieves the division of teaching contents according to certain layers, so it can be used to implement teaching in different stages according to students’ acceptance of knowledge complexity. Compared with traditional teaching mode, hierarchical teaching enhances students’ ability to understand knowledge and enables them to accept the knowledge implanted by teachers and to study in a progressive and gradual manner according to knowledge mastered. By applying the hierarchical approach in experimental teaching, teachers not only achieve the continuity and consolidation of theoretical knowledge, but also largely enhance the scientific literacy of college students.

To equalize the side effect that caused by the delay due to bus priority at intersections, three methods for green loss equilibrium to achieve bus priority were studied, including green extension, red truncation and phase insertion. Based on the assumption that vehicles arrives linearly, delay analysis were made at single priority request of non-saturated intersection when equilibrium is lost. Computing formula of intersection delay was presented with consideration of green light time non-priority phase loss and make-up during green light time. A timing optimization model was established which is known as normal traffic at rest phases, while objects to a function that maximize average delay at intersection. Based on Frank-Wolfe algorithm, solution came out under the diagonalized design. Instance analysis indicates the timing optimization model effectively balanced green loss at phases of non-priority, while deduced the amount of delaying at intersections. New delay calculation more explicitly described the delay change at intersections of bus priority.

In this paper, we use the time series model to analyze the impact of rural tourism to economic growth and employment rate. As rural tourism is a significant factor that will influence the regional economic growth and employment levels, so we make a statistical analysis of the impact of rural tourism growth (RTG), economic growth as gross domestic product (GDP) and tourism industry’s employment rate (RET). The result shows that: First, rural tourism will promote GDP increase. LnRTG at lag 1 period increased one percentage can drive LnGDP increase by 0.871 percentage; Second, rural tourism will also have positive influence to employment rate. LnRTG at lag 1 period increased one percentage can drive LnRET growth by 0.026 percentages; Third, LnRTG is the granger reason to LnGDP, which means rural tourism growth is the reason to the economic growth. At the same time, LnRTG is also the reason to LnRET. In addition, the rural tourism has a certain contribution degree to economic growth and employment rate, and can be used to explain the rising of GDP and employment rate. On this basis, we put forward the related policy suggestion.

Traditional membership functions in fuzzy SVM (FSVM) were designed based on the distance between a sample and its cluster center, which are irrational for dataset with non-spherical-shape distribution. A new membership function was proposed based on the distance between a sample and a hyper plane within the class. It overcomes disadvantages of traditional designing methods and improves the generalization ability of FSVM, while reducing the dependence of membership function on the geometric shape of sample data. Numerical experiments show that, compared with the traditional SVM and three FSVM with different membership functions, FSVM with new membership function has better classification accuracy. The New method is simple and its computation time is less.

This paper adopts the data ware house technology and data mining technology to establish a sports training assistant decision support system for long jump athletes. To make organic integration of the training factors for athletes, it applies scientific training theory and advanced training methods to the sports training management. We focus on the improvement of two classic data mining algorithms: association rules of Apriori and decision tree classification ID3. For Apriori algorithm, we improve the connections and pruning strategy when creating (k+1)-order frequent item set by k-order frequent item set, and the process pattern of transactions. For the defects of ID3 algorithm, we propose to reduce the computation of attribute gain selection when establishing the tree, and provide corresponding scheme to set the attribute importance. Then the actual examples are used to apply the improved models to the sports training assistant decision support system. The results show our algorithm improve the mining efficiency actually. The generated strong association rules which have higher association can be imported into knowledge library as important base for the sports training schemes.

In this paper, we aim to solve the problem of high-rise building construction project safety risk forecasting. The main innovation of this paper lies in that we convert the project safety risk forecasting problem to a classification problem, and design a novel QPSO-SVM model to implement the classification process. Before predicting the project safety risk, we present an index system, which contains six first-layer indexes, such as “Falling accident”, “Objects striking accident”, “Collapse accident”, “Mechanical injury”, “Fire disaster in construction”, and “Electric shock injury”. Particularly, 29 indexes are included in the second-layer of this index system, and these 29 indexes can effective represent almost all influencing factors in high-rise building construction project safety risk prediction. Next, we describe how to select optimal parameters of SVM classifier using the quantum behaved particle swarm optimization policy. Finally, experimental results demonstrate that, compared with other schemes, the proposed hybrid QPSO-SVM can forecast the high-rise building construction project safety risk with higher accuracy.

Smart Phones are portable and extensible, besides they can provide MEMS micro-accelerometer with good support. This article introduces a method of measuring the tension force of the cable-stayed bridge with the application of a Smart Phone. According to the FFT (Fast Fourier Transform) algorithm, the time domain is converted to the frequency domain while we program on the Android platform and the effective peak-picking algorithm is designed to determine the natural frequencies of the cables. An analysis of simulated signals demonstrates that the designed programs can accurately identify the natural frequencies with or without the disturbance and it can also compute the fundamental frequency based on the identified natural frequencies. With the fundamental frequency it goes on to calculate the tension force. A comparison of the result by adopting the method introduced in this article and the one collected from the JMM-268 tension force dynamic measuring instrument indicates that the Smart Phone has some difficulty in measuring the cables shorter than 40m; however, a less than 5% error is detected where the cables are longer than 40m.

The current and speed dual-loop control method was used in the DS operating mechanism control system. Due to the motor operating mechanism control system’s nonlinearity, the control error is large when the conventional double-loop PID control system was used. The fuzzy control algorithm combined with the PID controller can adjust the control parameters online and enhance its control capability of nonlinear control system – thereby reducing control error. Experiment results show that combined with fuzzy control algorithm of motor operating mechanism, intelligent control system can make real-time adjust the speed of switch contact to ensure the motion of stability and meet opening and closing speed requirements.

In order to improve the stability and reduce dashing time of micromouse in complex maze, the traditional turning trajectory and speedtime curves were abandoned. “S” turning method is proposed to achieve fast consecutive turning. For the “S” turning in straight way, controller fully considers passing of the last turning and leading of the next turning, with the help of compensation and navigation sensors to realize precise correction of micromouse position; For the “S” turning in arcs, different speeds are used to track different arcs, gyroscope records its rotation angle and does real-time angle compensation. “S” turning method is verified by micromouse based on STM32. Experiments of seven consecutive turnings show that the method can greatly improve the stability and reduce the turning time of micromouse.

As one of the important enhanced oil recovery (EOR) technologies, Foam flooding is being used more and more widely in the oil field development. In order to describe and predict foam flooding, experts at home and abroad have established a number of mathematical models of foam flooding (mechanism, empirical and semi-empirical models). Empirical models require less data and apply conveniently, but the accuracy is not enough. The aggregate equilibrium model can describe foams’ generation, burst, coalescence from mechanism, but it is very difficult to describe. The research considers the effects of critical water saturation, critical concentration of foaming agent and critical oil saturation on the sealing ability of foam and considers the effect of oil saturation on the resistance factor for obtaining the gas phase relative permeability and the results were amended by laboratory test, so the accuracy rate is higher. Through the reservoir development concepts simulation and field practical application, the calculation is more accurate and higher.

Basing on the theory of finite element method and modal analysis，the models of a bare plate and a piano soundboard are established in the ANSYS separately，then the two models' natural frequency and mode shape are calculated and compared. What is more，the influences of density and thickness on the piano soundboard's modal frequency are discussed. The result reflects that the piano soundboard's modal frequency is higher than the bare plate's and the piano soundboard vibrates in more complicate way. At the same time, it is found that the piano soundboard's modal frequency turns to be larger when the thickness turns to be larger and turns to be smaller when the density turns to be larger.

This paper concentrates on the problem of fault diagnosis for wind power generation system, which is a crucial problem for wind power industry. Firstly, framework of the fault diagnosis system for wind power generation is presented. This framework is made up of two main parts, that is, “local device module” and “remote diagnosis center”. In the local device module, wind turbines are connected to other servers through lower computers, and then data is transmitted to the remote diagnosis center. Furthermore, the remote diagnosis center can receive the data transmitted by the local devices and then discover faults by the proposed association rule mining algorithm. Secondly, in the proposed association rule mining algorithm, the opportunity and effectiveness of a specific rule is represented as the number of chances to utilize this rule and the average utilization ration of this rule, and then the rules with higher probability are preserved to conduct the Fault Diagnosis. Finally, specific wind power generation equipment is used to test the effectiveness, and experimental results show that the proposed method can discover different kinds of faults in the power generation system with high accuracy.
