The block length and key length of AES can be specified independently as 128 bits, 192 bits, or 256 bits, and the corresponding round time is 10,12, or 14.
By increasing the data block length, the accuracy of the results also increases.
For both random and block copolymers, therefore, the determination of the average block length and sequence distribution is highly significant to understand the polymer phase behavior.
The block length L can be further decomposed into L = [L.sub.T] + [L.sub.d], where [L.sub.T] is the length of training symbols in a block and [L.sub.d] is the length of data symbols in a block.
AES uses different key sizes of 128, 192 or 256 bits but restricts the block length to 128 bits.
For example, polyester thermoplastic elastomers have been produced by melt copolymerization of poly(tetramethylene ether) glycol (PTMEG) with dimethyl terephthalate and 1,4-butanediol [4], For these copolymers, a multiblock copolymer is produced possessing low [T.sub.g] polyether blocks, derived from PTMEG, randomly distributed along the polymer backbone amongst higher [T.sub.g] polyester blocks of varying block length. Although this synthetic method does not allow for control of block architecture or block lengths, it has enabled the production of important commercial polymers.
Hence not only does that LDPCA need more complex memory management, but also it does not support rate adaptivity for any variation in block length. Skipping highly correlated colocated blocks in block based video coding leads to variable block length and hence source nodes.
