Every block cipher involves a transformation of a block of plaintext into a block of ciphertext, where the transformation depends on the key.
The mechanism of diffusion seeks to make the statistical relationship between the plaintext and ciphertext as complex as possible in order to thwart (hinder or prevent) attempts to deduce the key.
Confusion seeks to make the relationship between statistics of the cipher text and the value of the encryption key as complex as possible, again to thwart attempts to discover the key.

Can a letter be repeated in the cipher text in a playfair cipher?
You mean your plaintext message the yes you can but you have to separate it with an x when you put letters in pairs, but in a key no.

What does sipher mean?
Do you mean cipher? A cipher is a method of encrypting in which a different figure (another letter, a number, a glyph of some kind) is substituted for each letter. A very simple cipher involves replacing the letters with a number being the number of the alphabetic order of the letter, so A becomes 1, B becomes 2 and C becomes 3, and so on. In this cipher 1-14-19-23-5-18-19 is Answers.

What is the relation between apparent diffusion coefficient and mean diffusivity on DTI?
Apparent diffusion coefficient (ADC) is a measure of water diffusion in all directions, while mean diffusivity is a measure of the average diffusion within a voxel. ADC includes the effects of both isotropic and anisotropic diffusion, whereas mean diffusivity reflects the overall diffusion within the voxel. In DTI, ADC is calculated as the average of the three eigenvalues, which correspond to the three principal diffusion directions and contribute to mean diffusivity.

Which parameters and design choices determine the actual algorithm of a Feistel cipher?
Block size: Larger block sizes mean greater security but reduced encryption/decryption speed. A block size of 64 bits is a reasonable tradeoff and has been nearly universal in block cipher design. However, the new AES uses a 128-bit block size.Key size: Larger key size means greater security but may decrease encryption/decryption speed. Key sizes of 64 bits or less are now widely considered being inadequate and 128 bits has become a common size.Number of rounds: The essence of the Feistel cipher is that a single round offers inadequate security but that multiple rounds offer increasing security. A typical size is 16 rounds.Sub key generation algorithm: Greater complexity in this algorithm should lead to greater difficulty of cryptanalysis.Round function: Again, greater complexity generally means greater resistance to cryptanalysis.
