To improve beamforming under low signal-to-noise ratio,a method based on stochastic resonance(SR)in a bistable model is investigated by using a frequency scale transformation method.

The expression of electric charge distribution on the surface for an ellipsoidal conductor is presented by utilizing the electromagnetic scale-transformation and the space electromagnetic characteristic.

A digital image resizing algorithm based on the linear relationship between the coefficients of two different sub-blocks transformations is presented,which possesses the capability of arbitrarily image resizing with fixed aspect ratio or no-fixed aspect ratio in compressed domain.

This paper proposed a fast and efficient image resizing method based on the spatial relationship of discrete cosine transformation (DCT) coefficients between a block and its sub-blocks.

In this paper, we present a digital image resizing algorithm based on the linear relationship between the coefficients of two different sub-blocks transformations, which possesses the capability of arbitrarily image resizing with Fixed aspect ratio or No-fixed aspect ratio in compressed domain.

Application of Scaling in Simulation of High Order Interconnect Model;

The approach of scaling must be applied into researches.

The invariability of orderly connections of decreasing mean residual life distribution in translation transform and scale transform is investigated and it is given that life distribution is a sufficient and necessary condition for decreasing mean residual life distribution.

It is proved that the DMRL ordering is maintained under the translation and scale transforms.

To deal with the disadvantages of Chan-Vese model(C-V model),such as convergence slowness,a level set image segmentation algorithm based on scale transform of edge detection function is proposed.
