A system for processing presentation instruments that includes a presentation instrument reservoir, a presentation instrument reader, a distribution stock holder, a distribution stock reader, two or more motor systems for advancing distribution stock and presentation instruments, and attaching the presentation instruments to the distribution stock. Also provided is a magnetic resonance imaging system including the cryogenic cooling system. Otherwise, a memory protection element is directed, in response to the received load secure region instruction, to form a secure memory environment. The backside of the second layer faces the front side of the first layer. Therefore, the present invention provides a system in which a performance test is performed in accordance with an access tendency of the application using the pool to thereby compute the tier capable of having the storage device added thereto, based on which the storage device can be allocated to an appropriate pool.
