A computer-implemented method for supporting administration of a multi-application landscape includes initiating, in a multi-application computer system, a business process that involves executing multiple applications and uses run control statements associated with process steps of the business process where a business process state is subject to change. The drive section has a reciprocating coil assembly to which alternating polarity control signals are applied during operation. This invention not only avoids the prior deadlock of the brake, but offers multiple segments of gradual braking effect, which offers the user multiple segments of tactual sensation. The Bayer-consistent ruleset results in a scaled image having a high degree of Bayer-consistency. A spring is disposed between the first and second links and configured to bias the second link downwardly relative to the first link, thereby biasing the rollers against a ground surface.
