The paper describes the current research situation of automotive ride comfort from two aspects of experimental and simulation. The dynamics model with five degrees of freedom of a bus is established, meanwhile the kinetic equations is also derived according to D'Alembert principle. A road simulation model of class B is also established on the basis of white noise method. Combined with vehicle model...
This paper studies partially decentralized control based on generalized predictive control for the load frequency control in deregulated environments. This method can decompose the complex interconnected power system into several subsystems. Compared with the decentralized control, it can take the coupling information into account, thus improve the performance of the control system but not make the...
Voice-based speaker recognition technique can be used in the identification of speakers. In such manner, Gaussian Mixture Model (GMM) can provide voice feature vectors' probability density model. In this paper, the Akaike's Information Criterion (AIC) is used to identify structures of the GMM models. The GMM parameter optimization is done by the differential evolution (DE) algorithm. During the optimization,...
In order to study the characteristics of electroencephalogram (EEG) induced by different types of music, we selected 58 volunteers (college students) with no musical training experience. Half of them are males and the rest are females. We finally adopted 49 experimental samples for further data processing. The results showed that: (1) music caused the changes of energy intensity in specific area of...
The Australian higher education sector has accepted that increasing work-related stresses can have a negative impact on the quality and productivity of academic life. Workplace stresses can have significant financial impact both on university budgets and the overall economy due to poor decision-making, health issues and accidents resulting from illness. Engineering academics that teach and/or research...
In this paper a comprehensive analysis of the content of information education issues for Pudong, Shanghai Regional Network Support Teacher Learning Community Environmental Studies, is conducted through various survey data using grey relational analysis model. The results provide several insightful suggestions to improve the training-studying network. For example, it shows that the motivation for...
Use of machine vision of tissue to indoor orchid plant growth status monitoring for plant growth, the state information, to improve the intelligent room of tissue has the vital significance. With the price of LED decreases, within the tissue more and more using LED for light, can significantly improve the plant growth and quality, but so on plant monitoring brings new problems, this paper proposes...
This paper has analyzed the principles of the traditional fault location methods which including traveling wave method, impedance method and the signal injection method. And it has introduced matrix method, neural networks, genetic algorithms, ant colony optimization, Petri nets and rough sets based on the distribution automation. Then this paper has pointed out their applications in the distribution...
In order to improve the reusability and efficiency of software development for in-vehicle information platform, a reusable and extensible object-oriented framework was proposed. Firstly, by analyzing the characteristics and demands in the related field, the meta-model of in-vehicle information platform was designed. Then, based on the meta-model and according to the domain feature, the framework was...
This text analyses present data mining technology based on association rule, carrying on an improvement to Apriori of frequency set method, and put forward to a multi-dimensional Apriori algorithm without producing candidates for election, according to which, give a investigation of data of undergraduate employment instruction center recent years of Jiamusi university. The result manifests that the...
For it has so many advantages multimedia supplementary teaching has been widely used nowadays. This paper introduces how to conform the multimedia and the environmental teaching on the basis of the practice of the environmental teaching. It also reveals several problems needing attention about the multimedia teaching process. In addition, it put forward that we should combine the multimedia teaching...
The relationship between passive smoking and female breast cancer with Meta-analysis were explored in this paper. The experiment was conducted in Department of Preventive Medicine of Qingdao University Medical College. Article that was about risk factors of female breast cancer were searched through Chinese journals full-text database and VIP Chinese science and technology journals full-text database...
In college English teaching (CET), evaluation is not only to check the results of learning but also a strategy to reform teaching model. The focus in the article is placed on the formative evaluation strategies to facilitate studentspsila interaction and autonomous learning. The principle of Criterion First and the evaluation interpretation strategies--- student team achievement division (STAD) and...
Some nonlinear physiological bio-signals like electroencephalograph (EEG) are not intuitive for analysis. Some mathematic model should be used to process the EEG data first. In this paper, theories and methodology of fractal dimension were introduced first. The enhanced dynamic fractal dimension model (DFDM) with sliding window was developed to analyze the nonlinear physiological bio-signals allowing...
The collaborative learning (CL) focusing on the teacher-student and student-student interaction and cooperation is a beneficial attempt to reforming the present teaching model. An experimental research was conducted to acquire some empirical evidence on CLpsilas effectiveness at the college level. Some CL strategies were exercised in non-major college English teaching (CET) of experimental class and...
