In this paper, a wavelet analysis is based on digital image watermark embedding and extraction algorithms, according to the algorithm designed and implemented in the visual sense with intuitive binary image watermark in the gray image of the hidden and extraction, and carried out a simulation experiment. The experimental results show that the algorithm research paper is feasible, from the visual point...
Shotcrete operation in coal mine face will produce a large number of cement dust. One of the main dust production equipments is concrete spraying machine. In order to decrease harm effectively from cement dusts generated in the coal mine face. Dust removal technology of concrete spraying machine is researched in the paper, and a new dust removal system is developed. According to producing cement dust...
A method based on curvature scale space to detect human head is proposed. The presented algorithm analyzes the head shape, and then gets the features different from other parts. Under the curvature scale space frame, the curvature of each point on the contour is calculated, combining the special features of head shape to detect the head. Experimental results show that the presented method can detect...
Residual current protective devices play an important role in electrical safety engineering. When dangerous residual current occurs, automatic disconnection of power supply can prevent dangerous residual currents which may cause burns, fires and electrocution. Discrimination protection is to ensure that only the faulty part of a circuit is de-energized by tripping of the protective device. Common...
To stimulate consumers' purchase willingness, producers must determine the reasonable selling prices and warranty length for their product. Based on the diffusion mode, a dynamic Stacklberg game of price and warranty was researched in this paper. Through this model, we got some conclusion about the supplier and retailer's optimal strategy.
Evaluation for urban sustainable development is very significant to the future development of urban. The analytic hierarchy process (AHP) has the special advantage multi-criteria evaluation method, which is very suitable for evaluation of urban sustainable development. In the study, AHP is applied to evaluate urban sustainable development. On the basis of analyzing the evaluation indexes, evaluation...
In this dissertation the research on the number of netizen in China is firstly developed, and then China's development of online shopping is analyzed. The developing countermeasures of Shopping at Network in China's e-commerce is put forward by looking at the number of network users to change the law.
In order to set up a water quality assessment system for Zhanghe river fittingly, a fuzzy comprehensive evaluation model based on fuzzy theory is studied. The application of this method to evaluate the water quality in Xida section is given as an example for demonstration. According to the environmental quality standard of surface water, the membership function is established. So as to ensure the...
The fly ash is rich with the actual situation in Handan, high-performance concrete was prepared by means of orthogonal design, according to test data, analyze water-cement ratio, the amount of fly ash, FDN content how to influence the 28th-day compressive strength and workability by means of range and variance. The aim is to explore the possibility that mix and use HPC as structure concrete in local...
With the development of market economy, farthest considers customer's satisfaction has become individual enterprise's management purpose,therefore customer satisfaction becomes especially important to evaluate the enterprise social performance. By analyzing the the concept of customer satisfaction, gives a method to quantitatively describe evaluation index on customer satisfaction, and establishes...
In order to ensure safety in coal production, full assurance is given for fully-mechanized excavated faces. Based on the vector supporting machine for regression (SVR), a model is established for predicting the gas emission in fully-mechanized excavated faces. The index system is analyzed and the model parameters are chosen. Then, the sample set of gas emission in fully-mechanized coal driving workface...
According to china standards ,an air displacement test of compressor should be made when the air-conditioned passenger train is maintained. In order to improve efficiency of maintenance , this article has studied the test system of air-conditioner compressor which is a part of air-conditioned passenger train . According to the request of the maintenance regulation, this article had designed the test-bed...
As we know AHP is better at computing index weight and comparing index in the same row than at classifying level, on the contrary, Fuzzy comprehensive evaluation method is good at classifying level. The advantage of the two methods is coupling to form a new method, which has been used in many areas. According to analyze constituent elements of intellectual capital, the index system was proposed by...
There are three broad types of legitimacy: pragmatic, moral, and cognitive (Barron 1998; Suchman 1995). Pragmatic of IT policy can help CIO balance budget and high quality of IT system. Moral of IT policy can help CIO design IT policy under the rules and standards. Cognitive of IT policy can help CIO design IT policy more smart and make the life cycle of IT system longer. Flow of design IT policy...
Software as a Service (SaaS) is a new kind of software application mode. In this paper, we discuss the application mode in the informationization in small and medium-sized logistics enterprises. The features of SaaS mode as well as its advantages in logistics industry are analyzed. SaaS platform suitable for the development of logistics industry is put forward. The business model and application mode...
Mutual interference between elemental images is a key problem of integral imaging. Some researchers presented a method to resolve the problem by limiting the aperture to limit the direction of incident light-ray, and the record region corresponding to each micro-lens had been separated, avoiding interference between adjacent elemental images. However, this method must be used at the process of picking...
Electroencephalography (EEG) is widely used in the field of neural engineering. EEG signals can describe the brain activities while the subjects with para/tetraplegia perform movement with their limbs. This paper reviews the research on the design of experiment, the different frequency bands of EEG signals and the data processing methods of EEG. According to the analysis of the previous studies, it...
Word sense disambiguation (WSD) is always an important and difficult problem that requires to be solved in natural language processing. This paper presents a new WSD method which is based on the mining association rules. The method can mine the association rules between the sense of the ambiguous word and its context, to construct an association rules-based database. At last the sense of the ambiguous...
The nurturing of innovative talent is the basis of a national increase scientific and technological innovation. How to cultivate talents with innovative consciousness and innovative abilities is the major concern of Chinese higher education. Based on in-depth analysis of mathematical modeling training and contest in this paper, we came to the conclusion that mathematical modeling training and contest...
