Land use and land cover change is one of the focuses in the study of global change in recent year. Land cover characteristics, at the global and regional scale, are very important for evaluating global environment status and simulating global environment scenario in the future. In order to provide some...

In this paper, earthquake triggering is described as the process of local instability of system in mathematical and physical way. And critical instability conditions of the fault in analysis domain are given. Based on elastic-plastic theory general constitutive relationship of the fault plane is derived....

an efficient resource schedule mode is built to solve the conflict of multi-user effectively in Tracking and Data Relay Satellite System in this paper. Mathematical model, improved optimizing algorithm and simulation results are given. Simulation results showed that the proposed algorithm can get the...

The internal parameters are important indexes for detecting the quality of the apples. This paper extracted spectral values of the apples from 400-1000nm with the hyperspectral image technology, carried out pre-treatment to original spectrums with MSC, performed regression analysis on spectral reflectivity...
