Multi-frame coding is supported by the emerging H. 264. It is important for the enhancement of both coding efficiency and error robustness. In this paper, error
This paper made use of approximate entropy (ApEn) to evaluate the complexities of frequency-hopping (FH) sequences. By defining the maximal randomness of sequen
Due to the large quantities of data and high relativity of the spectra of remote sensing images, K-L transformation is used to eliminate the relativity. An improved ISODATA(Interative Self-Organizing
The vacuum brazing of TiA1 based alloy with 40Cr steel was investigated using Ag-Cu-Ti filler metal.The experimental results show that the Ag, Cu, Ti atoms in t
