Abstract: Pen pressure has enabled a new degree of freedom for interactions in pen-based user interfaces, which has been shown the potential in relevant studies [6-8]. In this paper, we present a new pressure-based technique called Pressure Cursor for target acquisitions, in particular for small targets. Pressure Cursor enhances target acquisition by employing pen pressure as a control variable to enlarge the cursor. Pressure Cursor uses quick-release in the final determination of selecting a target, being different from traditional pointing technique (clicking). This technique is especially helpful for small targets. We conducted a quantitative experiment to examine the performance of this technique and to reveal its significant benefits.

Abstract: The practice teaching of specialty to the ability training of students of economic management field is very important. Some shortcomings exist in the practical teaching of the specialty system of undergraduate, which affect cultivation of the innovative qualified personnel. The author analyzes the existing problems, designs a scientific practical teaching system cooperating the universities with the enterprise to reform the existing system. The business processes in real enterprise has been introduced to intramural simulation training base to carry out the practice teaching of specialty cooperating the universities with the enterprises. It is mainly discussing the creative research way of the shortage of practical teaching resource for undergraduate based on the summarization of the experience gained in the innovation practice of practical teaching system of the information management and information system specialty in this paper. At the same time, the author explores the way to construct the demonstrative practice base of the information and management subject to solve the practical teaching problem of the specialty. The paper also discusses a few problems remained to be solved. On the basis of experiences and analyses, the author believes that in order to promote the construction of high-quality training system, the practical teaching system which cooperating the universities with the enterprise is the effective way to break the shackle of insufficient resources and ensure the quality of practical teaching.

Abstract: It’s a worthy research topic to use genetic algorithm for classification rules in data mining. In this paper, it was studied and researched in-depth. Firstly, we combined genetic algorithm and machine learning together, and then analyzed architecture of the genetic algorithm-based classification system, and also its development concrete structure was given. Secondly, we proposed a data classification rules learning system based on adaptive genetic algorithm, which can learn the classification rules accurately from the dataset. Finally the standard Play Tennis dataset was used for a closed test and after learning the system got three classification rules all with 100% accuracy rate, which fully demonstrated the feasibility of this algorithm.

Abstract: Bus reliability is essential for maintaining the steady state of electrical network in power plants and power transformer stations. Researches on techniques and methods to achieve highly reliable and intelligent bus protection are very important. A new bus protection method based on parameter optimization of the support vector machine (SVM) is provided in this study. Various types of fault data were collected and used as samples for sorting comparison and analysis of different bus faults. Data were obtained by comparing the SVM method with the artificial neural network (ANN) method. The results suggest that the SVM model using RBF kernel can better distinguish among bus normal operation and different bus fault types than the ANN model, and meet the precision requirements for bus protection.

Abstract: With the rapid development of software industry, in response to development in software technology, improve the market competitiveness of software professionals, many colleges and universities set java software language as their teaching language, and carry out lots of study about the Java language teaching reform and course content. compared to vocational college, the private college even more so for the market demand requires software to be more market-oriented needs of teaching, in this paper, out of the demand of market and java language its own characteristics, combined with characteristics of private colleges, we study discuss the training course in java language in private college teaching.

Abstract: This presentation proposed an autocorrelation-based signal detection scheme to get a better resulting. The signal detection scheme is combined by Autocorrelation Filter and an improved linear Minimum Mean Square Error (MMSE) estimator. The Autocorrelation Filter is used to reject the interference, and the improved linear MMSE estimator is used to get the least error. Both two methods are based on the non-overlapping property of the signals in autocorrelation domain. The theory consequence and Simulation results indicate that this signal detection scheme can achieve a high detection quality.

Abstract: For the sake of change our country the irregularity of the common high school athletics professional traditional teaching mode, improve a teaching target in the teaching, well embody the student's corpus position, relocate relation of teacher and pupil, build up the team study mode, development aware of self study, ego control, ego management of behavior habit, this text to study type organization theory the usage carried on a viability assessment at the teaching process and put forward to is the speculation of study of study type organization the study change of classroom.

Abstract: Small unmanned aircraft for civil and military has a wide range of applications. The design of traditional UAV avionics system is use discrete lines which link one point to another to communicate. It will make the system complexity, and the anti-jamming performance is poor. A new kind of design idea of unpiloted aircraft digital avionics system based on CAN bus is introduced, and this article also made a further study in the avionics systems’ critical subsystems, components and redundant design. The new avionics system, which used bus communication system has many good points, such as strong anti-interference ability, easily extended, simply configuration and so on. The system also has a certain value to promotion.

Abstract: In order to better adapt to the modern physics experiments under intelligent conditions, we examined a number of modern physics experiment the intelligent way from data acquisition and processing and concluded: Data collection can be attributed to two ways, one way is by means of computer device (such as sound card) to receive data, another way to install the data acquisition card (or frame grabber), moreover to install device driver in the computer; Modern experimental data processing is the main purpose of the intelligentization, with special software, fast data processing, and giving visual results. The results contribute to a better use of computer-based modern physics experiments.

Abstract: In daily life, we rely on other people's suggestions or by word of mouth or recommendation letters and book reviews printed in newspapers and general surveys, such as restaurant guides. However, the Internet's explosive growth has brought us information that anyone can be greatly difficult to digest. To cope with the flood of information, the personalized recommendation systems have been established to assist and complement the natural social process. These systems recommend users to select information that users may be interested in and filter out which users may not be interested. In order to alleviate the information overload problem, the author researches on the application of agent in personalized information recommendation system. The system collects user information of interest through the agent systems and queries the resources to filter and remove information that users do not need. It can provide users with intelligent and active information services.
