Muffin-tin approximation Muffin-tin approximation The muffin-tin approximation is a shape approximation of the potential well in an crystal lattice. It is most commonly employed in quantum mechanical simulations of the electronic band structure in solids. The approximation was proposed by John C. Slater. Augmented plane wave method (APW) is a method which uses muffin-tin approximation. It is a method to approximate the energy states of an electron in a crystal lattice. The basic approximation lies in the potential in which the potential is assumed to be spherically symmetric in the muffin-tin region and constant in the interstitial region. Wave functions (the augmented
Puyo Puyo! 15th Anniversary most cases, players are eliminated when he/she tops out, and the last player (or side) standing wins the round. The DS version of 15th Anniversary supports all multiplayer modes that the DS officially supports. In this mode, players without a copy of 15th Anniversary can play along with those that do. The only difference between playing with a copy and without a copy is that the download and play version does not contain voices or battle animations. The game is functionally compatible, for the most part. Therefore, both the DS Download and Play modes and direct connection modes are accessible
