Three-dimensional fluorescence spectrometry is a rapid analyzing method and is widely used in dissolved organic matter (DOM) characterizing and fingerprinting. In this present work, three-dimensional emission and excitation matrix (3DEEM) fluorescence spectrum was applied to characterize the fluorescence properties of dissolved organic matter in farmer household tourism wastewater and municipal wastewater...
The change of farmland Compaction is one of the important restrictive factors of agriculture production in reclamation land. There are similar in the destructive land by coal mining and by earthquake, so we can learn the reclamation technology each other. According the analysis of spatial variation of the reclamation farmland compaction, the article gets the conclusion that the reclamation farmland...
In this paper, a highly robust digital video watermarking technique is given. First of all, the watermark information is encrypted by Arnord transform. Then it is embedded in DCT domain by high-frequency coefficients correlation algorithm in RGB frames of source video file. The field tests indicate that the video file with the watermark information is transparent, and strong anti-aggressive.
