Research of Overall Optimization Based on a Series of Data Structure Courses Teaching Content
Статья научная
“Data Structure” is the core of computer science courses, which is closely related to “Programming Language”, “Discrete Mathematics”, “Operating System” and “Compiler Principle”. The five courses have a strong relationship between academic edge in the teaching content, teaching model and teaching method. This paper proposes a method of overall optimization based on a series of data structure courses teaching content. The method explains inherent relationships among the courses so as to avoid to be disconnected each other. As a result, general efficiency of the five courses teaching is increased and the students’ ability of the data abstraction and algorithm design is improved.

Research of P300 Feature Extraction Algorithm Based on Wavelet Transform and Fisher Distance
Статья научная
With the aim to improve the divisibility of the features extracted by wavelet transform in P300 detection, we research the P300 frequency domain of event related potentials and the influence of mother wavelet selection towards the divisibility of extracted features, and then a new P300 feature extraction method based on wavelet transform and Fisher distance is proposed, which overcomes the drawbacks of no systematic feature selection method during traditional P300 feature extraction based on wavelet transform. In this paper, both the BCI Competition 2003 and the BCI Competition 2005 data sets of P300 were used for validation, the results showed that the proposed method can increase the divisibility by 121.8% of the features extracted by wavelet transform, and contribute to the followed classification.

Research on Financial Distress Early-warning of Listed Companies Based on GA-SVM
Статья научная
Based on financial management and enterprises of early-warning theory, this paper constructs a financial distress early-warning model using GA-SVM. First, it uses listed companies appearing in Shanghai Stock Exchange and Shenzhen Stock Exchange in 2007-2009 as sample books. Defining ST listed companies which have abnormity of finance status as signature of the listed company's financial crisis. Then it uses the data in the financial statements known to the public as the input feature vector and combine genetic algorithm and support vector machine. Use Taking an empirical research with the financial distress early-warning model. Test results of the demonstration study shows the model has a superiority in predicting financial distress.

Research on Resource-based and Theme-oriented College English Teaching
Статья научная
Guided by the sociocultural theory and input theory, a research was conducted to probe into resource-based and theme-oriented college English teaching. It discusses the principles of college English language materials selection and how theme-oriented teaching activities enhance meaningful language input and output. The results show that the teaching mode can improve students’ multiple intelligences on a large scale and facilitate the transformation between students’ explicit knowledge and tacit knowledge. Being resource-based and theme-oriented, the mode helps broaden students’ horizon, cultivate their humanistic quality, enhance students’ information quality and boost the effects of language learning.

Research on Strategies and Patterns of Research Teaching
Статья научная
In order to improve teaching level, quality and effect, more and more attention has been paid to the tendency of research teaching being one part of teaching reform in higher education. The research teaching model is proposed that opposite to in unidirectional knowledge instruction teaching model primarily, it refers to the teaching system melting study and research as a body. The research teaching model is the research undergraduate college teaching basic teaching model. Starting with the significance and the conduction of research teaching, this paper puts forward and analyzes several patterns of research teaching, discusses the important role of teachers in these patterns and proposes some strategies as well as suggestions.

Research on teaching of Java Exception Handling
Статья научная
Exception handling is an important and difficult part of the Java programming’s teaching and training. The paper points out and discusses the two outstanding problems in details during teachings, that are how can make students master exactly the basic ideas of exception handling and locations need to be handled by exception handling methods in Java programs. Furthermore proposes a kind of teaching process which gradually shows the puzzles during the learning of students starting from the case by combining the heuristic teaching with the practical case of significance, and figures out step by step the solving methods, namely the knowledge points, which have to be learned about exception handling. Visualization and simplification are their advantages, which facilitates the students’ learning and understanding. The teaching practice shows that the good teaching results have been achieved.

Retrieval of Motion Capture Data Aids Efficient Digital Learning
Статья научная
This study aims to integrate digital technology with the animation production process. By experiencing and learning how body joints move — with digital technology as the learning aid — students can create results similar to motion-captured body movements. This then can be applied to animation design with the hope that it can help the students in their future employment. This paper focuses on digital learning and technology to bring forth body movement production principles and an integrative framework. The study results can offer training to front-end talents of the digital content industry. In addition, the main contribution lies in the research and development of training methods and linking them with digital learning techniques. This can provide directions for the development of upcoming relevant cultural industrial courses. This paper will use human-like character animation —that is comparatively harder to represent in 3D computer animation — as the example. It will also discuss the variations in results achieved by different production processes. At the same time, feasible training directions are provided as references for learning digital technologies.

Review on: Analysis of an IoT Based Blockchain Technology
Статья научная
Blockchain is the technology which in the last decade has influenced our lifestyles most. Bitcoin is a word used frequently for Blockchain. For example, scalability and protection issues that stands up because of the immoderate numbers of IoT items within the community. The server/client version calls for all devices to be connected and authenticated via the server, which creates a single point of failure. Therefore, shifting the IoT machine into the decentralized course may be the right selection. One of the popular decentralization structures is blockchain. The Blockchain is a powerful technology that decentralizes computation and management methods that may resolve many of IoT troubles, in particular safety.Many Blockchain still confuse Bitcoin, even if it's not equal. Bitcoin is one of several applications are available in Blockchain technology. First of all we present an outline of blockchain architecture and compare a few popular consensus methods in various blockchains. This study also introduced the entire blockchain ecosystem of all the articles we examined and summed up. Furthermore, analyses and consensus models are conducted on many blockchain platforms. Finally, we analyze key issues which are necessary for the future of blockchain technology in these key fields to be broadly available.
