Because of the shortcomings such as intensive labors, low accuracy data, and no-timely information of the manual survey methods for collecting dynamic origin-destinations, a method for expanding dynamic origin-destination data based on mobile phone locations from samples to collectivities is designed according to the status with a large number of users and advanced location technology on mobile phone,...
Land reserve is an important mean for the intensive utilization and optimized allocation of land resources. But due to the influences of various uncertain factors in the operation of land reserve, there is some certain deviation between the actual return and expected return of land reserve, and this brings the possibility of sustaining losses. How to correctly evaluate and evade land reserve risks...
With regard to the increasingly prominent issue of cultivated land protection, it is necessary to establish a fast and effective early warning system that can have a real-time monitoring on cultivated land protection status. This thesis takes urban fringe area with prominent changes in cultivated land as the survey area, on the basis of comprehensively application database, System Dynamics (SD) and...

Precise indoor positioning is becoming increasingly important in commercial, military and public service applications for tracking people and asset. Ultra Wide Band (UWB) can provide high accuracy position with strong anti-jamming and low power consumption. By combining orthogonal frequency-division multiplexing (OFDM) with multi-band, MB-OFDM systems can capture multi-path energy more efficiently...
