The preparation and characterization of blends of a series of dicyanate monomers such as 2,2′‐bis(4‐cyanatophenyl) propane (DCDPP), bis‐4‐cyanato‐biphenyl (DCBP), bis‐4‐cyanatonaphthalene (DCN), 3,3′‐bis(4‐cyanatophenyl)sulphide (DCTDP), 3,3′‐bis(4‐cyanatophenyl)sulphone (DCDPS), and the diglycidyl ether of bisphenol A are reported. These copolymers are combined with a montmorillionite nanoclay and...
Steganography has long been a means of secure communication. Security is achieved by camouflaging the secret message. In this paper, we present a Genetic Algorithm based Steganography using Discrete Cosine Transforms(GASDCT) and Genetic Algorithm based Steganography using Discrete Wavelets Transform(GASDWT). In our approach, the Discrete Cosine Transform and Discrete Wavelet Transform are applied...
