A method for manufacturing a creped fiber web is provided and includes providing a rotating cylindrical dryer surface, providing a creping adhesive composition or coating package having a pH boosted at least 0. In one particular embodiment, the techniques may be realized as a method of operating a computing system to facilitate visualization of a backup environment. The resulting transfer of momentum to the foundation bolt reduces impact of the armature on the valve seat and causes the armature to more quickly reach a defined rest position in which the solenoid valve is closed. An estimate of the resulting received signal quality is obtained and used for another power adjustment. An optical disk drive includes an analog-to-digital converter configured to convert low-pass filtered and gain-adjusted versions of photodetector output signals into at least one digital signal and the digital signal processor.
