Link prediction is a basic problem in the research of social networks. At present, most link prediction algorithms are based on the features extracted from network structure, few research concerns the effect of natural attributes of nodes for creating a link. In this paper we develop a novel way to predict links based on Random Walk algorithm using the information from both the network topology and...
Using hydrochloric acid solution and rare earth concentrate mixed heating method, which is prepared a new polymer flocculant polymerization of rare earth coagulants (PRE), studied the amount of coagulant, pH value, slowly stir intensity, slowly stir time, sediment time on polymerization of rare earth coagulants coagulation effect. And will fuse rare earth coagulants (PRE) with common coagulants IC...
Sickbed arrangement is an important part of daily management in the hospital. Since the service time for different type of patients varies, the queuing system here, with multi-random input flow, can not be solved accurately by using classical queuing theory. Based on the analysis of patient information, we apply the simulation method into the sickbed arrangement system, and take the average waiting...
The risk of chemical site imposes on nearby vulnerabilities is of great concern and remains undefined. Risk severity index is devised to illustrate the risk levels in a simple and understandable way, with SLAB modeling the exposure of vaporizable substances. Risk and vulnerability mapping are both presented on the platform of GIS, and the distribution of vulnerability in different risk leveled areas...
The purpose of this paper is to analyze the spatial characteristics of the total population distribution in 39 cities near the Lancang River at the end of 1978 year to 2007 Year .The inherent laws of spatial distribution of population can be revealed by the spatial autocorrelation analysis based on population density data, we can analyze the spatial characteristics of population for each cities and...
Along with the deepening of the state-owned business remanufacture, more and more state-owned businesses have implemented the reform of the stockholder's rights multiplication. The whole employee stock ownership as one form of the stockholder's rights multiplication is also being applied widely. In the whole employee stock ownership enterprise, the factors such as the contradictions of staff's dual...
The change of land use/cover associates with the nature of land recourse and the manner that humankind applied on. This study concerns one of the hot issues about global changes. The land use/cover data could provide essential information for the purpose of protecting environment and fulfill sustainable development. This thesis mainly had the following results:1, Land use/cover maps for the years...
Based on the theory of core competence, the paper analyzes construction enterprise's core competence from the perspective of knowledge capital. It establishes evaluation index system of construction enterprise's core competence, and then uses BP neural network to set the model of calculating construction enterprise's core competence. This model avoids subjectivity and uncertainty brought about by...
In this paper, the city input-output efficiency analysis which includes electric power input has been done based on the extension models of DEA to Chinapsilas typical cities. At first, it established index system of comprehensive evaluation of city efficiency, and did input-output-effectiveness evaluation which include electric power input for China's 23 cities in 2006 and sorted by the urban development...
Using the thought of the value -chain to represent the valuable activities of information management, also importing the concept of the important contribution of the knowledge activity , thus lays the foundation on the theory for the performance prism to evaluate information management, pointing out the framework of the performance prism. Point out the concrete indices of every panel. Calculate the...
Based on the theory of core competence, the paper applies intellectual capital theory to analyzing construction enterprise's core competence and constructs the index system from the point of intellectual capital. Further, drawing on the method of analytic hierarchy process and information entropy of fuzzy matter-element, this article establishes a fuzzy comprehensive evaluation model. Finally, it...
