For fault diagnosis and data processing in coal mine safety production, this paper gives a kind of data processing method based on Grubbs's criterion and weighted data fusion. The method is based on intelligent detecting system and data fusion technology, it eliminates measurement data containing mistake errors by Grubbs's criterion first and then determines weight number in weighted data fusion, at last, it calculates fusion estimate to carry out fault diagnosis. The measured data verification shows that this kind of data fusion algorithm has advantages of more accurate results, simple algorithm and strong practicality, etc.[...] Read more.
After analyzing the basic concept and method of Aspect Oriented Programming (AOP), the method based on AOP was presented to solved the security validate, permissions verification, log and so on. Compared to the conventional Object Oriented (OO) approach, AOP technology could avoid such problems as tangled code and scattered code, and had obvious advantages in raising the component reusability, optimizing processes and reducing the system complexity. Finally, an integration example of permissions verification in workflow system was provided, and the implement based on AOP was provided too.[...] Read more.
To deal with some problems of ERP software for textile enterprises, such as immaturity, poor adaptability to business management model and difficulties in meeting enterprise requirements, this article proposes an ERP system implementation method using MDA(Model-Driven Architecture)concept and the method has been in full application in textile enterprises. Such method may provide customized ERP system quickly based on specific information management requirements. It may vary with the change of management requirements in an economic, cost-effective and fast way.[...] Read more.
In this paper, an effective method of design fuzzy logic controller is introduced based on LabVIEW. The steps of setting membership function, fuzzy rules and fuzzy interference are introduced in details of design fuzzy controller. It is implemented in the oven temperature control system, which has practical value for engineering.[...] Read more.
With the development of the science and technology, Complex Product and System (CoPS) plays a more important role in modern economy and society. This paper aims at the problem of quality control in the CoPS innovation. Through studying the CoPS characteristics and different innovation mode from the mass production, we established the quality chain model. The model is a process network in which nodes are consist of the suppliers, manufacturers and customers etc. the lines between the nodes is process of quality transmission. Compared with the process model of normal innovation, the process added four steps (task decomposition, analysis of knowledge demand, outsourcing selection and system integration) which reflect the Complexity of CoPS innovation. Traditional processes such as trial-manufacture and R&D process are involved in the module development. Despite that some scholars have a profound interest in the process of quality transfer in he quality chain and put forward some method solve quality problem of CoPS innovation, up to now little suitable and quantization method is presented. In the paper, quality houses are adopted to deal with the relation of quality chain nodes and interpret the process of quality transfer. Quality requests of one node are converted the technique indexes of another node in the quality house. At last an example is given to illustrate that this approach can improve quality control level more than the traditional statistical process control method and effectively reach quality management of CoPS innovation.[...] Read more.
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.[...] Read more.
This paper starting from the original grey differential equations, through finding the relationship between the raw data and the derivative of its , constructed a new white differential equation which equal to the original grey differential equation, at the same time, getting the new GM(1,1)model which closer to the changes of data. Through the modeling and prediction of the standard index series, this model not only adapts to low growth index series, but also adapts to high-growth index series, and the simulation accuracy and prediction accuracy are high.[...] Read more.
A majority of domestic universities currently possess conditions of carrying out computer aided instruction, however, most of them are immersed in pure applications of multimedia classroom systems. In such application environment, teachers of literature courses generally have bias on understanding of multimedia, thus they pay more attentions to application of multimedia teaching tools and ignore the effective combination of multimedia technology and literature courses with its own characteristics. Literature courses primarily allow students to capture the beauty of Chinese language and its styles through permutations and combinations of them, and then enjoy pleasure of character plots, deep thoughts and feelings and so on. Based on this understanding, computer-assisted instruction should reasonably arrange proportion of multimedia elements: text, images, audio, video and others. Meanwhile, education of magnetic personality of teachers and predominance of teachers during teaching process should not be neglected. At last but not least, proper body language, fine grasp of the classroom rhythm and suitable display of multimedia elements can dramatically improve the effectiveness of delivery, and then achieve the purpose of humane education.[...] Read more.
This paper describes some basic concepts in contrastive linguistics, and discusses its function in language teaching. And it compares the English proverbs containing the animal word horse with the equivalent Chinese proverbs. It aims to find the correspondence of the animal word horse in English and Chinese languages and illustrate the cultural phenomenon behind the translation. This paper finds out that the correspondence is very important and can help to understand the languages and the cultures and contribute to the teaching of language. Relevant study should be based on the cooperation and effort of both linguistics and teachers.[...] Read more.
A simulation model of eddy current retarder is designed, including 1/4 vehicle model, eddy current retarder model, tire model. Based on the PID and neuro-fuzzy controltechnique, twokinds of control algorithm on constant speed control heavytruckare designed. On the built simulation system, the control algorithm is simulated and test. The results show that the neuro-fuzzy controller can implement high precision and strong robust control effects on control of eddy current retarder system.[...] Read more.
Mechanical manufacturing technology is a compulsory subject of mechanical engineering specialty and one of important processional fundamental course. Therefore, the course reformation is significant in the entire higher education reformation process so that new training plan can successfully carried out to train high quality talent. A novel course construction and content are proposed from the easy to the difficult. On the other hand, the analogy teaching method as well as the guide teaching method is created to attract students’ attention to mechanical manufacturing technology. The proposed reformation strategies for mechanical manufacturing technology can help student to improve basic abilities of analyzing and solving problem.[...] Read more.
According to the characteristic of Industrial and commercial Management specialty, especially “stronger practice”, in order to promote the transform of professional knowledge between explicit knowledge and tacit knowledge, the expansion model of SECI is introduced into the explorative analysis, and corresponding teaching methods and models are raised to facilitate the mastery and flexible application of students’ professional knowledge.[...] Read more.
