A method for fast resampling of remote sensing imagery has been developed based on the nature of the geometric distortion of raw imagery.

The paper proposes a new approach of anisotropy analysis of spatial distribution pattern of plant populations based on the data resampling technique combining Ripleys L index.

Data sampling interpolation algorithm based on computer sampling theory and its application in modern numerical control system;

The interpolation algorithm for involution is proposed in accordance with the principle of data sampling.

According to the basic idea of data sampling interpolation s time division,under the condition of machining quality being guaranteed,the cutter-center path is programmed into some straight line segments,consequently the feed rate between adjacent lines is almost constant.

Analysis and countermeasures of problems about unusual sampling data in microprocessor-based protection;

First, it gives a method of extracting signal frequency from sampling data Second,it also gives the range of relative errors by the relative errors formulation Finally, the theory is verified under the environment of Matlab and the results are also given The conclusion may be taken as a tutor for research of extracting signal frequency from sampling dat

The record of CAT is a series of sampling data.

Chaotic anticontrol of a class of two-dimensional continuous time linear systems using sampled data;

The single parameter sampled data feedback control directs the system to unstable equilibrium point with only one parameter.

The system state variables are sampled at a given sampled period,and a sine function constructed by the sampled data is used both to form a discrete-time state feedback controller and to make the continuous-time,stable and linear systems chaotic.

This paper describles the design and implementation method of the virtual battery test system based on FPGA and USB interface technology, And explained the design principle based on FPGA central controller especially, the design of Read and Write module of USB endpoint, the design of muti channel data sample module and the realization of USB interface driven.
