Watermarking is the requirement of today‟s digital media. Embedding of watermark provides security against piracy & attacks .Watermarking is also useful for provide owner identification to digital media. Inthis Research papera new algorithm, for digital image, based on Hybrid DWT-DCT Transformation is proposed. A host image (grey scale) is initially DWT transformed up to 3-level.Thencomputation...

Several lines of evidence concerning the vertical abundance profile of water in the atmosphere of Venus lead to strikingly unusual distributions (the water vapor abundance decreases sharply in the immediately vicinity of the surface) or to serious conflicts in the profiles (different infrared bands suggest water abundances that are discrepant by a factor of 2.5 to 10). These data sets can be re...

The aims of this article are to provide an up-to-date review of the methodological features and substantive results of published epidemiological surveys of the prevalence of pervasive developmental disorders (PDD).
