A method of wavelet neural network (WNN) for correlation of base-level cycle is given. Wavelet neural network is introduced first. Then, a new method of Vectored of well logs is proposed. Through the training which causes the wavelet neural network memories the cycle pattern characteristic of the curve, and using the trained wavelet neural network to identify the memory cycle pattern of the well vectored...
Usually, the optimistic method of underground metal mines is selected by some mathematic methods, empowered the safe, technical and economic indicators with weight. Due to make the selection of mining method more scientific and rational, Firstly, the Safe indicator is considered separately based on the perspective of corporate social responsibility and fuzzy comprehensive evaluation (FCE) method is...
A novel infrared face recognition method based on radative energy and decision fusion is presented in this paper. In this method, according to Stefan-Boltzmann's law, the raw thermogram images are transformed to the radiative energy images. Then, the block-DCT is applied to get the local features of face. Finally, a method of decision fusion based on probability is presented to obtain the final result...
In view of the problems existed in library management and service work, we designed a RFID Intelligent Book Conveyor using Radio Frequency Identification (RFID) technology and embedded technology, we also exploited GUI using Qt integrated development environment. This book conveyor is a portable equipment with complete functions, friendly interface and convenient operation. It can greatly improve...
Virtual Screening (VS), a productive and cost-effective technology in quest for novel lead compounds, is a new approach in the pharmaceutical industry. This kind of applications belongs to the family of large scale loosely coupled parallel applications, whereas concurrent tasks are independent of each other, and are most suited to run on the Grid environments. However, there are some important practical...
Eutrophication of coastal waters has gained increasing attention during the recent decades. In the present study, the spatio-temporal representation of coastal water environment is described, and a tidal flow and pollutant transport numerical model, coupled to GIS, is established to simulate PO4 concentration in Bohai Bay, China. The result shows that linking GIS with simulation model enhances communication...
Corner detection is an important research topic in the field of computer vision and pattern recognition. Accurate corner detection plays a vital role in the completion of many computer vision tasks, such as image matching, object recognition, camera calibration and motion analysis, etc. According to the different implementation methods, it described four kinds of corner detection methods in detail,...
The Grid Architecture for Computational Economy (GRACE) is a model, which uses for reference the competitive market mechanism in human society to manage the resource. However, in the model, once the trade is set up, there is no way to monitor whether the seller (i.e., resource owner) has provided the services or the buyer (i.e., user) has accepted the services according to their commitment. Thus a...
A real-time sensor array self-calibration method is presented in this paper to reduce the ship-based flexible array element coordinates uncertainty in short baseline passive localization system. Six composite sensing elements are deployed to form the flexible array. Three of them emit direct spread spectrum DPSK pulse to measure the distance between six elements. Coordinates of these elements were...
Pipe network is a complex spatial distribution system. In order to define the internal structure of the pipe more, this article aims to analyze the section spatial topological structure of the pipe network from a 2-dimensional GIS pipe network map by using a generation algorithm of transverse section drawings and vertical section drawings. Based on C# and ArcEngine, this algorithm visualizes transverse...
This paper introduces the concept, development, key features, applications of cloud computing. The difference to grid computing is discussed. Eight kinds of typical open source cloud computing projects are described, the security reference models of cloud services are given. Cloud computing security challenges and countermeasures are discussed in this paper.
3D-GIS is the current research hot spot, which defines the topography, not the internal structure. Therefore, 3D-GIS based on 3D-LD is proposed, which applies the 3D visualization management of person and things. The simulation indicates that it is feasible and has broad market prospect. Moreover, the information resource platform based on the 3D-GIS is constructed. It actively pushes on the cities'...
Warranty service has an important role in the product transactions. The price is related to length of warranty period of product. Considering the reality, based on the consumer utility theory, assuming free replacement policy and the product failure with Weibull distribution function, this paper studies the differential pricing issues for the product with multiple warranty. This paper analyzes the...
Experimental Teaching is the specific application of theoretical knowledge and practice of professional skills to test students in an effective way. 21st Century Financial professionals must not only be able to adapt to the information age environment, but also be able to meet the changes of modern enterprise information management, therefore, financial class teaching more professional disciplines...
Dramatical increase of private automobiles speeds up the consumption and the demand of petroleum. Based on time-series data of private automobiles and petroleum consumption of China from 1990 to 2008, this paper carries on cointegration test and Granger Causality Test, and sets up an error correction model to quantitatively analyse the relationship of the short-term fluctuation and the long-term equilibrium...
During the development of private enterprises, their management mode usually features gradual evolution from family management to professional management. Likewise, HR management of private enterprises often develops from enterpriser-oriented to professional manager-oriented strategic management. In this paper, the authors introduce some reference information related to strategic HR management, describe...
In the era of the knowledge economy, corporate survival and development is closely related with the knowledge employees. The output of knowledge employees depends largely on the quantity and quality of enterprise incentive for them. In view of the current problems of knowledge-based business in staff motivation, this paper puts forwards several proposals from aspects of incentive mechanism, incentive...
The convergence of industrial structure in Yangtze River Delta increased internal competition between regions and waste of resources, the further development of regional economy was then hindered. These consequences ,to a considerable extent, caused by the local government behavior. Based on the calculation and analyzing of similarity coefficients of industrial structure of the Yangtze River Delta,...
Software process play an important role in improving the quality of software products. Formal software process model is conducive to the accurate description of software processes. A software process meta-model is a formal tool used to define software process models. In this paper, a software process meta-model SPMM is designed. Firstly, five important properties in software processes are discussed...
P2P traffic identification model based on machine learning is proposed. The FCBF(Fast Correlation-Based Filter) feature selection algorithm is used to select the P2P flow attribute features subset. A P2P flows identification model is built based on decision tree and FCBF. 10-fold cross-validation method is used to validate the proposed model. Experimental results show that the method of P2P traffic...
