It is still difficult to locate reference point for low-quality fingerprints in fingerprint recognition. In this paper, a novel algorithm based on quadratic B-spline wavelet is proposed to deal with this problem. The main idea of the paper is to make a progressive analysis on the gradient-changing of the orientation field and combine the gradient information at different scales together. Due to multi-scale...
Virtual cultivated land refers to the quantity of cultivated land resources needed during the production of goods and service. This paper chose four kinds of main grain products i.e. rice, maize, wheat and soybean, and calculated their trade volume of virtual cultivated land. The result showed, from 1978 to 2007 the average annual net import of virtual cultivated land came to nearly 4.4 million hectares...
Service trade increasingly becomes an important criterion of a country's overall international competitiveness assessment. The purpose of this thesis was to analyze China's current service trade competitiveness and prompt strategies for China's service trade development. This thesis empirically studied China's service trade of TC and the RCA index, and comparatively analyzed service trade between...
In order to further promote quality education and meet the needs of social development for talents, China's education field started a new wave after the main education, researching education and so on, it was a bilingual teaching. This thesis started from the theories of bilingual teaching models, analyzed the several models of bilingual teaching, then it compared bilingual teaching models of the...
The recursive digital filter technique was used to separate annual baseflow of main hydrological stations in the Upper Reaches of Heihe River. The methods of moving average, Mann-Kendall abrupt test and wavelet variance were employed to explain the characteristics of the annual change of baseflow and analyze the reasons of change. The results indicated that the Baseflow Index (BFI) were higher and...
It is very important to detect the reference point effectively and accurately, especially in nonminutiae based fingerprint matching and fingerprint classification. In this paper, an effective algorithm based on block level for fingerprint reference point detection is proposed to simplify detection process and improve accuracy of the position of the point. The method is simple in the preprocessing...
Sustainable development of resource-based enterprises is dynamic, open and complex system involving five subsystems: resource, economy, society, environment, technology, and management level. Three are various fields related to its study, including enterprise management, resource management, ecology, environmental science, demography, engineering, economics, and sociology. The inherent complexity...
FCM algorithm is an important algorithm in fuzzy pattern identification. It has significant application value in theory and practice. And whether clustering results are reasonable or not is belongs to cluster validity problem. In this paper, based on the Shannon entropy and fuzzy variation theory, considering the geometry structure information of data sets, we give a new cluster validity function...
This paper examines the relationship between corporate governance and corporate performance. An overall set of measures are constructed to evaluate the practice of corporate governance in Chinapsilas civilian-owned listed enterprises. Factor analysis is introduced to construct a comprehensive performance variable. The result demonstrates better corporate governance mechanism is not associated with...
The application of reversed A2/O process into practice and the effect of removing nitrogen and phosphorus are studied based on the principle of reversed A2/O process. The practical application shows that reversed A2/O process is a new process that is simple and highly-efficient and is adapted to the municipal wastewater condition in China.
The paper summarizes current technologies of dynamic web service composition. Then, based on the existing technologies, we raise a new solution for dynamic web service composition. We make use of the knowledge of domain ontology. On the one hand, the user’s requirement was broken down into a series of abstract web services, according to the logic of business processes. On the other hand, through establishing...
The primary goal of this research is to develop a novel intelligent fault diagnosis method employing neuro-fuzzy transductive inference algorithm (NFTI) in order to solve the the global model application problem, as well as the global availability of the model and sample data set. The method is characterized by that a personal local model which is established for every new fault symptom input data...
Under assumption of labor force relatively overmuch, this paper investigates agglomeration of horizontally FDI in host country in view of limited number of firms or much enough number of firms. The research indicates: Number of firms will affect agglomeration of horizontally FDI in the host country; horizontally FDI won't invest and agglomerate in host country under the market construction of firm's...
XML indexing is an important method for accelerating query processing. Existing structural indexes suffer from the problems of redundant traversal and lack of scalability for answering multiple queries simultaneously. In this paper, we present a novel index called as SIMP, which is an efficient XML structural index for multiple query processing. We first introduce an index to cluster the concerned...
This paper proposes a transformation algorithm of abstracting information based on the semantic path, by constructing XML index tree. The signature information of more subtle granularity and significance can be found quickly in the XML document according to the tree and transformation algorithm. Through signing multi-semantic path and information, XML multi-signature can be realized, data security...
