Link formation is the foundation for understanding, analyzing and modeling friendship networks. We analyzed a friendship network comprising 190 students at Northwest University for Nationalities with attributes (gender, nationality, hometown, major, class and dorm). We found that link formation is dominated by a combination of effects arising from geographic proximity and homophily. Attributes dorm...
In order to solve the complexity of the evaluation process of the urban water supply performance and the drawbacks that data envelopment analysis (DEA) can not be re-sort for effective decision making units, a supper efficiency-data envelopment analysis (SE-DEA) model based comprehensive decision-making scheme for the urban water supply performance is established and a set of options to reflect the...
Along with the economy development and the industrialization progress quickly, watershed pollution in cities is growing seriously. It's difficult to achieve the goal of improving the water environment with the traditional water pollution control theory, as it's more emphasis on the end approach. Evolution of watershed relates to climate change, geological features, land use, animal changes, human...
This paper uses fuzzy neural network method to establish simulation model about the evaluations of customers' beer tastes and preference degree. It explains the methods of building, training and simulating networks in the development environment of MATLAB software. And it does network training and error testing by the actual data to prove this model is feasible.
The rapid urbanization process has resulted in innumerable ecological and environmental problems which are still worsening. This paper presents the advantages and disadvantages of several causal-chain models such as PSR, and introduces a new ecological-security assessment model-DPSIRM, which is a causal-network combined with GIS spatial analysis method. After investigating the healthy state of Dalian...
Public transport is one of most complicated systems in a modern city. Based on the grey system theory, a grey relational assessment model on service quality of urban public transport is put forward. On the Basis of above, this method is applied to evaluate the service quality of public transport in one northern city.
The importance of System-On-Chip (SoC) validation continues to grow with the increase of design size. How to measure the completeness and quality of validation approach? An innovative domain coverage metric is proposed in this paper. Domain methodology is based on a geometrical analysis of the domain boundary and takes advantage of the fact that point on or near the boundary is most sensitive to domain...
