This paper presents a Web page indexation model. In this model, a Web page is not viewed as a whole, but as a combination of a set of blocks based on their visual rendering, where ...
Error diffusion halftoning is a popular method of producing frequency modulated (FM)halftones. In FM halftoning the dot size and shape is fixed (equal to one pixel) and the dot fr...
—Jacket matrices motivated by the center weight Hadamard matrices have play some important roles in signal processing and communication. In this paper we proposed a notation call...
Security of a modern block cipher is commonly measured in terms of its resistance to known attacks. While the provable security approach to block ciphers dates back to the first C...
Constructions for hash functions based on a block cipher are studied where the size of the hashcode is equal to the block length of the block cipher and where the key size is appro...
