Based on geographical and semantic features of remote sensing image, the paper presents a universal remote sensing image data model, and analyzes the logical structure and storage methods of this model. Based on the model, the paper puts forward a remote sensing image retrieval method, and makes analysis of the process of remote sensing image retrieval. At last, on basis of computer and database technology,...
Determining the weights in a combination forecasting is an important problem. We can translate the problem of computing weights into estimating the importance of attributes. Inclusion degree is one of the methods of computing importance of attributes. So this paper introduces a new method of computing weights based on inclusion degree. The example illustrates that the weights computed by inclusion...
This article analyzes the current Web graphic processing technique, and then it puts forward a new model of object grouping database and technology of rapid graphic refreshment based on the incremental data. Later on it discusses collaborative graphic editing technology to organize GIS data more effectively and improve graphics interaction processing efficiency under network environment.
This paper calculates capital allocation efficiency (short for CAE) of the total, domestic and foreign capital (3-funds enterprises) in Chinapsilas manufacturing industry and explores this thought into the allocation of labor. Yearly CAE and labor allocation efficiency (short for LAE) are calculated out by sectional data model while capital and LAE of the total, domestic and foreign capital in different...
Monitoring and predicting human cognitive state and performance using physiological signals such as Electroencephalogram (EEG) have recently gained increasing attention in the fields of brain-computer interface and cognitive neuroscience. Most previous psychophysiological studies of cognitive changes have attempted to use the same model for all subjects. However, the relatively large individual variability...
