A model of comprehensive evaluation of regional power quality based on multilevel extension method is first put forward in this paper. A new index system is established, with the characteristic indexes include voltage level, load capacity, number of users, importance of the user, user sensitivity and quality performance of the subregions. Then, the subjective weighting algorithm based on improved...
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.
Through the analysis of the relevant power energy consumption factors of the large-scale public buildings, the integrated model based on multiple linear regression and self-regression methods is attained, of which the least square algorithm is chosen to make parameters estimation. -test and -test are applied to verify its availability. After power consumption data of large-scale public buildings acquired...
The content of technologies integration in regional land resources security and control system is analyzed in this paper, and on this basis, the key supporting technologies are explained. A theoretical framework is constructed, which chooses GIS technology as the platform for technologies integration, while organization and management of data and models as the center, and thus to realize specific...
