A new chaotic image encryption scheme based on permutation and substitution in the Fourier domain is presented.Fractional Fourier Transform(FRFT)is used before
The pyrolysis of 5-HMF was investigated using density functional theory methods at B3LYP/6-31G++(d, p) level. Two possible pyrolytic pathways were proposed and
