This paper introduces Computer Science students' need to learn team interaction skills. A model that emphasizes the importance of structuring team interactions for effectiveness in Computer Science education by ensuring that key variables are present, is then offered. Findings regarding an analysis of this model in terms of positive interdependence, individual accountability, interpersonal and small-team skills, promotive interaction and team processing is further detailed. This is done by indicating to what extent, and how, educators ensured that the key variables were implemented. The paper finally offers conclusions, including a summary and an indication of the importance of this research.

This paper analyzes the relation between financial development, urban facilities and China's urban household consumption using dynamic panel model. The empirical results show that the expansion of the size and efficiency of financial institutions has a delayed impact on household consumption, but the effect of urban facilities is not clear. Except coverage rate of tap water, coverage rate of gas and per capita public green area, the effect of other 3 variables are not significant. Besides, we also find that education and medical expenditure and house price have significant effect on household consumption, but don't find powerful evidence of the effect of macroeconomic and demographic factors.

Folk paper cutting art is the folk carrier of Chinese nation deposited for thousands of years, contains the elite of national culture and art, which is one of the important representatives of excellent Chinese traditional culture. The introduction of folk paper cutting art to the curriculum system of college art education can make up for the shortages of higher education, pass on and protect national art, uphold patriotic passion, enhance folk culture and art education, improve the humanistic attainments of students in colleges and universities, restrain corrosive influence of adverse culture, shape physical and psychological health of college students, learn the elite of folk art creation and improve aesthetic level.

Arcade building is a unique architectural form in Lingnan Area of China. Its overhead space should provide a more comfortable passage space. However, during the stage of reconstruction design of Nanning Pedestrian Street, arcade buildings were completely retained in the structure and historical spirit as possible, whereas thermal comfort as a passage space was ignored. Through the analysis of field investigation, it was suggested that tree-planting, water-holding pavement and membrane structure would be effective cooling strategies. These passive strategies can improve thermal comfort in arcades and surrounding passage space. In order to optimize the thermal improving effect of these strategies, an optimal design was carried out based on computer simulation. Simulation results can be visualized in color images on a PC. From these images, a designer can easily understand where is cool, what degrees surface temperatures could be reduced in the passage space.

Variable precision rough set model is the extension of rough set model, which introduce the beta parameter based on the basic rough set theory, that is, allows a certain degree of misclassification rate existing. This paper presents the web mining algorithm based on variable precision rough set in e-commerce, analyzes the limitation of the reduction methods based on variable precision rough set theory. The experiment shows the CPU Time in the attribute numbers. indicating that VPRS is superior to normal algorithm in web mining in e-commerce. The experiments show the algorithm could flexibly and dynamically web mining and therefore provide a valuable addition to the field.

The phenomenon of bifurcation and chaos occurs in mine power grid under certain conditions, showing as seemingly irregular oscillation, sub-synchronous resonance, or voltage collapse phenomenon. This poses a threat to the safe operation of power system. Research on the control of bifurcation and chaos provides a theoretical guidance to improving the stability of power grid, which is of great significance to mine safety production. Taking the parameter drift and disturbance of mine power grid chaotic oscillation system into consideration, we use adaptive control method based on dynamic fuzzy neural network (D-FNN) to control the second-order model of mine power grid to the set target. Good control result verifies the effectiveness of the D-FNN control strategy.

With the deepening of information construction, Web architecture is widely used in various business systems. While presenting convenience, these new technologies also introduce great security risks. Web security has been a serious issue of information security, and SQL-injection is one of the most common means of attack against Web services. SQL Injection often changes the structure of SQL statements. This paper proposed a self-learning approach to counter SQL Injection which can learn automatically the structure feature of all legal SQL statements to construct knowledge library based on SQL syntax tree in safe environments, and then match every SQL statement with knowledge library to find whether the structural feature has been changed in real environments. If successful, this SQL statement is legal. SQL statements which fail pattern marching are not determined as illegal immediately. Then, we take depth-feature check based on Value-at-Risk, and identity the true illegal SQL statements. This method which combines mode-matching and character-filtering can reach good results. Experimental results prove that this proposed approach holds good performance and perfect protection for SQL Injection.
