The Savonious rotor is a slow running vertical axis wind turbine (VAWT) which gets stabilized after a certain period of functioning. This work aims to assess the results of an aerodynamic study concerning a Savonious rotor. The computational fluid dynamics (CFD) is a technique used to solve the airflow around the wind turbine rotor. In this paper, the turbulence models standard k-ε and shear stress transport (SST) k-ω are the turbulences models. A three-dimensional study of the problem has been conducted. Firstly, the moment of static forces acting on the rotor blades have been compared to with experimental results. Secondly, the integration of the equation of motion of the Savonious rotor with one degree of freedom (1-DOF) rigid body dynamics model. Implicit schemes for unsteady Euler equations have been used to perform dynamic simulation.

Students of software engineering are facing with the problem of lacking enough practices. Joining a real project and developing software in a team can always bring them valuable experiences and lessons. To help students obtain software development capabilities, this paper introduces a teaching model based on computer-supported collaborative learning (CSCL) theory, as well as specific teaching methods. A teaching research undertaken in a university uses this model and the result indicates that students could acquire much more knowledge and experiences about software engineering from this kind of collaborative learning.

This paper focuses on a simulation research by way of combining nonlinear adaptive Kalman filter with PID control, aiming at resolving the space attitude and the PID control system for an underwater robot. The results reveal that the nonlinear adaptive Kalman filter, compared with general Kalman filter PID control system, can inhibit white noise pollution more effectively. Thus, the control effect has been improved.

Digital museum has become an important mode in culture communication with the great development of information technology. At the same time, the digital museum depending on physical articles is restricted by communication subjects in terms of collection and integration of the original materials. Due to the fact, thematic digital museum mode is proposed based on the digital museum in this paper, which has great advantages in propagation of culture. Moreover, this mode would develop the resources and the educational functions of digital museum. As an example, “Cizhou kiln” thematic digital museum is introduced to describe the structure, content and realization of the present mode. This work can offer some fundamental theory to the development of digital museum.

The purpose of this study was to construct an E-situated learning system using problem-based situated learning methods, in order to increase learning efficiency. The design of the system can be divided into two parts: (1) the development of the learning platform, devising materials management and interactive learning interfaces, helping teachers create multimedia teaching materials that target different clinical problems. (2) Development of the learning assessment indicator system, which includes consolidating learning indicators, analyzing the learner's route of learning, and providing teachers the learning results as a feedback. In order to verify that the electronic situated learning system is able to help increase a student's observational and judgmental strengths, pre- and post-tests were conducted. The results indicated that (1) the average learning time was reduced by 46%, and (2) by providing students with different cases with the same manifestations, the rate of correctness increased from 66.5% in the pre-tests to 70.25% in the post-tests. From the analysis of the experimental results, it was found that problem-based situated learning is able to strengthen the students' observational and judgmental capabilities.

The conventional Java based method of data encryption and decryption exists such problems as low efficiency and complicated programming. To resolve these problems, an efficient implementation which combines the third-party open source Poco library with JNI is proposed in this paper. Developers can create their C++ function library using Poco and finally generate a dynamic link library file, then Java will call the needed functions by mean of JNI. The implementation is highly portable and available on many different operation systems and has passed the testing on Windows XP as well as Ubuntu. Different implementations are compared in efficiency, the result shows that the performance improves significantly.

A two-DOF dynamic equation with cubic nonlinear stiffness was established. The response of the system to the four kinds of path spectrums which are cement road, washboard road, pebble road and fishscale pits road is obtained by Runge-Kutta method and the vertical vibration serviceability is obtained by simulation calculation. The curves of vibration serviceability-damping coefficient under the four kinds excitations of path spectrums are also obtained which supply theoretical basis for dynamic design of the tractor.
