Abstract: In the application of the classification, neural networks are often used as a classification tool, In this paper, neural network is introduced on motor imagery EEG analysis, the first EEG Hjort conversion, and then the brain electrical signal is converted into the frequency domain, Finally, the fisher distance for feature extraction in the EEG analysis, identification of the study sample was 97 86% recognition rate is 80% of the test sample.

Abstract: After years of development, the neural network classification, clustering and forecasting applications have a lot of development, but the neural network has the inevitable defects, if you enter the attribute set, the classification boundaries are not clear, convergence low efficiency and accuracy, there may even be the state does not converge, using rough set theory, the right value to modify the function to be modified, and joined the contradictions sample test module, after the use of EEG to verify reached the deletion of number of features and the purpose to improve the classification accuracy.

Abstract: A new Operator Fuzzy logic in the theory of semantics integral has been defined. In the way of combining syntax and semantics of the formulas, this logic which named SIOFL can give an index to the truth degree of a proposition formula. It can give the quantum measure of default information with the obtained knowledge. With the character of non-monotonic, the logic system is suitable for approximate reasoning when some information is lacked.

Abstract: Distributed Generation that is usually installed in the client or near them is a kind of power equipment whose capacity is generally small in the tens of kilowatts to tens of megawatts, which becomes a hot research area at home and abroad in recent years. The method for power flow calculations on distribution networks face new challenges because of the access of distribution generation, while, modeling of distribution generation is the basis and precondition for the research of power flow calculations on distribution networks with distributed generations. The article studies the modeling of distributed generations in power flow calculations, anylies most distributed generation forms, focuses on the interpretation of the principle and essence of them, and establishes theoretical models apply to the flow calculations. The modeling lay a solid theoretical foundation for the power calculations on distribution networks with distributed generations.

Abstract: The present study analyzes some problems of the current higher vocational education on urban rail transit by investigating personnel cultivation of rail transit in higher vocational colleges in China. Subsequently, the researcher deeply discusses the following aspects: speciality establishment, curriculum system construction, systematic textbooks, teaching format, practice and internship equipment, faculty troop, cooperation between colleges and enterprises etc. Finally, the result reveals that the current situation of urban rail transit in higher vocational education is not optimistic, and needs to be reformed.

Abstract: Training is an important means to accumulate human resources and strengthen the core competitiveness of an enterprise. As the last step in training, the evaluation of training effectiveness has been the weak point in large number of enterprises for a long time. The evaluation method of skills training effectiveness based on cloud models is provided. This method blends together the subjective and objective information. At the same time, the method integrates the fuzzy and random completely, achieves the mutual conversion of qualitative and quantitative evaluation, and deals with the uncertainty of the system evaluation indexes effectively.

Abstract: With the advance of computer multimedia technology and English teaching reform, the scope of computer multimedia application to education has become wider and wider. During the ESP teaching course, the teacher may stir students’ interests by means of multimedia technology, optimize the ESP course and improve teaching efficiency. The writer also points out the limitations and strategies we should pay attention to in the application of multi-media to ESP teaching in order to achieve an ideal teaching effect.

Abstract: The emotional education is a significant goal of education. Only pay more attention to the emotional factors in network teaching, we can cultivate the healthy human nature learners. This paper will introduce the Moodle platform and have a thorough discuss on how to use Moodle to realize network emotional education from the teaching function Moodle included.

Abstract: In traditional way of ELT, the teacher was the center of all teaching activities. There have existed many disadvantages in the traditional ELT which is against quality-oriented education. The application of web-based multimedia teaching model changes the teacher-centered model; it puts importance on the cultivation of student’s independent spirit and helps students change from the passive listeners to the active participants, thus develops student’s ability of using English and their learning autonomy. However, research discovers that about 30% of students do not hold positive opinions towards the application of multimedia and nearly half teachers have trouble in making good use of multimedia. (The results are shown in Table 1 and Table 2) This paper explores the changes that multimedia has brought to ELT and the difficulties and problems in applying it, suggests that schools increase opportunities for teachers to receive multimedia training, thus better integrating multimedia technology into college ELT.

Abstract: This articles take the iOS program design course as an example, briefly introduces the process to design and development this iPad- based mobile learning platform and the main function of it. This platform not only have the general video watching, resources sharing function, but also provides BBS, notes, resource download to meet the different needs of learner .
