Image steganography is a scheme that hides secret information in a cover image without being perceived.Most swish supreme glide track white of the existing steganography methods are more concerned about the visual similarity between the stego image and the cover image, and they ignore the recovery accuracy of secret information.In this paper, the s
Similarity in community composition declines as distance between locations increases, a phenomenon that has been observed in a wide variety of freshwater, marine and terrestrial ecosystems.One driver of the distance-similarity relationship is the presence of environmental gradients that alter the suitability of sites for particular species.Although

In order to investigate the influence of soot on the anti-wear property of molybdenum dialkyldithiocarbamate(MoDTC) and zinc dialkyldithiophosphate(ZDDP), the soot was added into different oil samples and then a four-ball machine friction experiment was carried out on the samples.Results showed that when the mass fractions of MoDTC and ZDDP were 0.
A novel attempt is made to quantify the qualitative interpretation of barotropic instability in terms of counterpropagating Rosssby waves (CRW) as proposed by here Hoskins et al.(1985).Although many investigations have been devoted to this quantification in the past, a minimum resolution grid point model is chosen here as a tool where complete insi
