Study on time-lapse seismic time difference in layered medium;

Analysis of time-lapse seismic time difference in layered strata;

Based on the spectral correlation theory,a model and algorithms of time difference of arrival(TDOA) estimation for cyclostationary signals are presented firstly,and then this model is used for TDOA estimation of the DSS signals in the highly noisy and jamming environment.

Target Cooperative Tracking in Multiple Stations Based on DOA and TDOA;

A Method of Dual-Satellites Geolocation Using TDOA and FDOA and Its Precision Analysis;

Calculation Method for Location Accuracy of Tri-station TDOA System Based on Experimental Data;

Acoustic log moveout correction based on variation of borehole diameter.;

Analysis of P-Wave nonhyperbolic reflection moveout in VTI media;

Shear moveout reflected the porosity variation,it was feasible to compute porosity by using shear moveout.

And the necessity to set up resources links and its influence on calculating activity floats were analyzed.

When adjustable amount for a job is calculated, limits on the activity and some constraints are analyzed to eliminate job s virtual float.

This paper researches the regular relationship of activity floats in Network diagram and establishes several mathematical models.

Referring to the classical location method attributed to Geiger, this paper brings up a scheme according to time difference of arrival(TDOA) to locate the position location of the survivor in earthquake and its feasibility is verified by a series of experiments.

Cramér-Rao lower bound(CRLB) is derived for multi-satellite passive location based on time difference of arrival(TDOA) and frequency difference of arrival(FDOA) and its necessary and sufficient conditions are given.
