Urban expansion is always an important element of the urban issue. And the remote sensing technology is a powerful tool in extraction of urban areas and analysis of urban expansion. In this study ETM+ images are used to detect the land use change of the urban and urban fringe areas in Hangzhou. The directional flow and driving forces of the urban expansion are then analyzed to study its urbanization...
This paper proposes the approach of analyzing risk of deep excavation engineering based on fuzzy theory. By using fuzzy mathematical method, the risk assessment model is established, and a practical method on fuzzy comprehensive assessment on risk of deep excavation engineering is proposed, and the practicability of this method is verified in a real engineering projects.
The goal of federated identity management is to allow principals, such as identities and attributes, to be shared across trust boundaries based on established policies. Since current Single Sign-On (SSO) mechanism excessively relies on the specifications of Circle of Trust (CoT), the need for service collaboration from different domains is being addressed on CoT. For the motivating issue of the cross-domain...
Pulse diagnosis is one of important diagnosis methods in Traditional Chinese Medicine (TCM). Recognition of TCM pulse has received more and more attention in recent years. Extracting proper features is crucial for satisfactory classification. While most of previous methods for feature extraction of TCM pulse have no specific correlation with the mechanism of TCM pulse, a hemodynamics method is used...
Effective evaluation to the significance of the items is an important basis to process inventory management. In this context we not only consider item's own attribute such as item's profit and item's cost, but also the effect of item association to process inventory classification. Using association rules related theories we build a new evaluation criterion based weighted dollar-usage and propose...
The risk assessment of engineering project is an important basis for the risk management countermeasure in project actualization phase. This paper brings forward design discipline of risk assessment index system, and founds risk assessment index system of engineering project based on it. In view of the shortcomings of traditional fuzzy assessment, which are coarse quantification of qualitative indices...
In order to overcome the subjective randomness in traditional fuzzy comprehensive evaluation, the weight value is modified based on the differential degree of evaluation indices, a new model for comprehensive evaluation-entropy weight fuzzy comprehensive evaluation model is established by using the concept of entropy in information engineering science. Then the model is applied to the optimization...
