In today " s world there is a great need for low power design and area efficient high performance in DIP (Digital Image Processing) systemIn this paper the proposed method presents a parallel single-rail self-timed adder. It uses recursive method for performing multi bit binary addition. This design attains good performance without any special speedup… (More)
A pseudorandom permutation is used to encrypt an original image, and the encrypted data are efficiently compressed by discarding the excessively rough and fine information of coefficients generated from orthogonal transform. After receiving the compressed data, with the aid of spatial correlation in natural image, a receiver can reconstruct the principal… (More)
Splicing system is proposed to model the recombinant behaviour of DNA molecules. This paper introduces the concept of double cross-over splicing in circular arrays. The theoretical result as persistence in circular array splicing give rise to important properties.
Splicing systems are generative devices of formal languages introduced by Head (1987) to model biological phenomena on Linear and Circular DNA molecules. Certain recombinant double cross-over behavior of DNA molecules are formalized various actions of splicing Schemes on Linear and Circular DNA molecules. We examine the double cross-over splicing scheme… (More)
