A system control unit causes a diagnosis monitor to display a plurality of sample images generated by changing one or more image processing parameters used in image processing of an X-ray image. For example, the illustrative embodiment controls the pitch of a supercavitating projectile by shifting its center of gravity. To control in-sequence delivery of the Internet Protocol packets for the given TCP connection, the radio link control entity inserts and uses port-specific sequence numbers in the RLC protocol data units which carry the Internet Protocol packets for the given TCP connection. The active resistance can be a passgate. Thus, it is easier for transportation and maintenance, with less cost and down-time. M1, where ti is a set of coset representatives taken from a unit cell of the input signal lattice, and D is a dilation matrix having a determinant equal to M.
