The carbon dioxide is the major component of greenhouse gas in energy consumption. Because of different energy varieties and consumption patterns carbon emissions are different. Therefore, the estimate of carbon emissions should be calculated one by one according to different energy variety which bases on the clear range of energy consumption counting. In accordance with the carbon emission factors...
This paper makes an attempt to address the scaling problem of Leaf Area Index (LAI) and to analyze the propagation of scaling effect of LAI. On the basis of the Taylor series expansion and following the general scaling procedure, it is demonstrated that the magnitude of the scaling effect is the product of the degree of the non-linearity of the retrieval model and the spatial heterogeneity of input...
The prototyping is to realize an original model quickly according to the communication between users and developers to improve the model quality and decrease the faults. According to analyzing the basic characteristics of the mining recycling economy, a spatial decision support system (SDSS) development strategy by using the prototyping is proposed to integrate the technologies of the rapid prototyping,...
Aims at the issue of passenger turnover structure, based on Markov theory building the multi-product alternative forecast model, obtained the future passenger turnover structure under the stable state trend of transportation development. In practice this method has the strong feasibility, through the prediction of the passenger turnover this thesis could provide a viable research ideas for the harmonious...
This article used statistical data of recent two years. Under the condition that RMB satisfies Markov property, we used Markov chain to compute the frequency matrix and transition probability matrix and moreover, we predicted the future trend of exchange rate. We also simulated the original data using AR model, and added residual factor that is from analysis of Markov Chain. Finally, we got a model...
A new model of network security assessment is proposed in this paper. A single IT entity is evaluated through EAL; The composite IT entities are evaluated by CAP. The model analyzes the security value of network elements, and adopts the Geometric mean method to determine the security value of the entire network. The effectiveness of this method is validated through the evaluation of a practical system.
