    Based on the actual CPI data of Anhui Province from January 2010 to August 2018, this paper constructs a price index prediction model based on non-stationary time series analysis (ARIMA)and conducts empirical analysis. The results show that the absolute and relative absolute errors of the model are within a small fluctuation range. This shows that the model fits well and the predicted value approaches the true value. Finally, the CPI data from September to November 2018 in Anhui Province is predicted using this model.

    Abstract: Based on the theory of dynamic game, this paper analyzes the evolutionary game relationship between regulators and people忆s livelihood financial institutions. Through the evolutionary game theory, the key factors affecting the stability of the game model and the equilibrium stability strategy of the two main bodies are obtained. The research shows that rent-seeking variables play a key role in the evolution of game behavior and the formation of equilibrium and stability strategy. Strengthening supervision is not necessarily the most efficient way to solve people忆s livelihood financial problems. Appropriate punishment intensity can effectively adjust the evolution of game behavior. Through further analysis, this paper puts forward some suggestions,so as to provide reference for promoting the innovation, coordination, orderly and efficient development of the national people’s livelihood finance and supervision mode.

    Abstract: The Hirota bilinear method is used to obtain the single soliton solution, the breather solution and the Lump soliton
    solution of the (2+1)-dimensional KdV equation. The motion trajectory, effective volume and effective kinetic energy of the Lump-type soliton are obtained by theoretical calculation. The kinetic feature quantity is then found by the superposition of the single soliton solution and the breather solution to find out the phenomenon that the breather is swallowed by a single soliton,and explore the particle characteristics such as collision, rebound, absorption and splitting in the interaction process of Lump soliton and single soliton. Thus the phenomenon behind the reflected laws of physics is revealed.

    The almond-based activated carbon was used as adsorbent for treating low phenol concentration wastewater; the adsorption equilibrium experiments data were fitted with Langmuir, Freundlich, pseudo-first order and pseudo-second order equations. The results showed that adsorption equilibrium data fit Langmuir model. Equilibrium adsorption capacity decreased with the increasing temperature in low concentration. However, it related to "adsorption-desorption" balance when phenol concentration was higher. The adsorption process could be described by pseudo-second order kinetic model well, and chemical adsorption was the rate-limiting step.

    Al/MoO3 nano-thermite has attracted wide attention due to its high heat released and fast combustion speed. In this paper, clubbed MoO3 with homogenous morphology was prepared by hydrothermal method at pH=1, reaction temperature 180°C and reaction time 24 h. Then Al/MoO3 nanocomposite coatings were assembled by electrophoretic deposition. Moreover, themorphology, structure, output of heat and combustion properties of the prepared samples were analyzed comprehensively. The results show that when the voltage is 200 V, the electrophoresis time is 10 min, the concentration of polyethyleneimine (PEI) is 1% and the ratio of two components is 2.13, the heat released of Al/MoO3 thermite reaches 3555 J/g, and the combustionphenomenon is violent. It is indicated that the micro-morphology and reaction ratio between Al and MoO3 have significant effect on the reaction performance of the Al/MoO3 thermite.

    In recent years, carbon nanotubes derivatives become the research focus because of their unique physical and chemical characteristics and broad application prospect. Functionalized carbon nanotubes were synthetized mainly by the methods of
    covalent bond and non-covalent bond. The former is the use of carbon nanotubes produced oxidation with other functional active groups occurring etherification, amidation, alkylation and in-situ polymerization reaction; The latter makes organic functional group molecular winding, coating or grafted in carbon nanotubes surface by non-covalent bond. In this paper, the synthesis methods of carbon nanotubes derivatives are reviewed, especially the methods of covalent bond and non-covalent bond are introduced. The existing problems of the synthesis methods are also analyzed. In the meantime, the application prospect of nanotubes derivatives is discussed.

    The finite element analysis of the Baja racing car's brake and its connection piece has been completed. The UG software is used to establish the connection piece 3D model, which is imported into ANSYS workbench to carry out its structural statics analysis, and the structure of the connection piece is checked and optimized. The main improvement scheme is to add ribs in places where stress concentration occurs and to hollow out properly. The modal analysis of the brake disc is carried out; the natural frequency of the brake disc is calculated, and the vibration mode is analyzed. The results show that the reason for the brake disc falling off is not the resonance torsion between the brake disc and the outside world, but the brake disc is subjected to a large axial force when driving, which acts on the rivet connecting the brake disc and causes the rivet to fail. The analysis results can provide reference for the design of the Baja racing car's brake and its connection piece.

    Course scheduling in colleges and universities is complicated and tedious. Scientific arrangement of teaching sites and experimental equipment can improve the teaching effect. Based on the study of various constraints of the course scheduling
    system in colleges and universities, the structural equation model (SEM)of the course scheduling system is constructed by
    using AMOS software to solve the direct and indirect effects of key factors on the course scheduling system in colleges and
    universities. The results show that the maximum path coefficient of performance input query management is 0.754, followed by
    teaching plan management 0.665, curriculum information management 0.547, and the minimum impact is teacher-student
    evaluation management, with a value of 0.403. Accordingly, it provides countermeasures and suggestions for promoting the
    reform of education and teaching, improving the quality of teaching and avoiding resource waste.

    A vehicle classification model based on deep learning is proposed to deal with complex traffic scenes. The model consists of two parts: vehicle detection model and classification model. A region-based convolutional neural network (R-CNN)method is used in the vehicle detection model to extract a single vehicle image from a disorderly background image. This step provides data for the next classification model. In the vehicle classification model, an image of a vehicle is included into a CNN model and a feature is produced, and then a joint Bayesian network is used to implement the classification process. Experiments show that the method can effectively identify vehicle structures and models in traffic images.

    Abstract: The advent of MOOC brings the traditional teaching mode new chances as well as challenges. However, it is difficult
    to provide a complete learning experience due to the lack of face-to-face communication. SPOC not only utilizes the advantages of MOOC, but also it deeply integrates the traditional classroom teaching of higher education. Therefore, to solve the problem in this topic, a blended teaching mode is designed based on SPOC in this study. The teaching and learning process is reconstructed by combining online learning and offline learning, integrating classroom teaching with flipped classroom, and complementing classroom and extracurricular. To validate the proposed blended teaching mode based on SPOC, the C language programming course is carefully chosen in this study. The influence of blended teaching mode on learners忆learning behavior and learning effect is investigated from the aspects of learners忆learning behavior, school record and learning evaluation. The results show that the teaching effect of blended teaching mode is better than that of traditional teaching mode, and it has a postive impact on improving learners忆learning participation and self-regulated learning ability.
