Threshold algorithms and functions of wavelet shrinkage in speech enhancement;

Denoising method based on combining multi-scale product with wavelet shrinkage;

After eliminating the high frequency component by threshold quantizing of the wavelet shrinkage, signals can be reconstructed for the de-noising aim.

Argument on the completeness of quantum mechanics spanning two centuries is outlined, including the arguments between Einstein and Bohr, the probabilistic interpretion of quantum mechanics, the "reduction of wave packet", the "EPR argument" which is incorrectly called "EPR paradox" in many papers and books, "hiddenvariable theories" and the "Bell inequality".
