It is proposed in this article that small towns should be dynamically planned,and the circulative accumulation is an important inner motive force for small towns development.

The relation between the two-dimensional cyclic convolution and the discrete reconstruction convolution is educed.

This paper proposes a new algorithm for the computation of Discrete Cosine Transform (DCT) with odd prime length using cyclic or skew cyclic convolutions.

Convolution is converted to cyclic convolution,and also FFT is employed to calculate cyclic convolution.

The result shows that the Birkhoffian system has generalized energy integrals and cyclic integrals.

Routh and Chaplygin equations for variable mass nonlinear nonholonomic system in noninertial reference frame are extended,and the cyclic integral and its condition of existence for the system are given.

In this paper, the D Alembert-Lagrange principle and the generalized chaplygin s equation for variable mass weakly nonholonomio systems moving relative to noninertial reference frame are established at first, and then the generalized energy integral and the generalized cyclic integral of the dynamical equations in the case of one-order approximation for the systems above are studied and presented.

GPS signal C/A code phase measurement using FFT and circular convolution;

Research of Circular Convolution in OFDM System with Fixed Waveform TGI;

The algorithm firstly determines the mensurability of the signals and the lowest sampling rate for correctly detecting the signals,and calculates the PN code phase at this sampling rate,then gradually increases the sampling rate and calculates the PN code phases at those sampling rates using circular convolution,until the expectant precision is acquired.
