An apparatus for conveying a substrate or sheet through a printing machine comprises a drive roller and a baffle assembly forming a path for the substrate past the drive roller. More specifically, this invention relates to a building cladding that is passively responsive to sun elevation angles, is multi-functional, and is substantially uniformly ornamental when viewed from common viewing positions. A node ordering module generates a node order based on a cycle-cut set identifying at least one of the dependency links that is part of a cycle in the weighted directional dependency graph to create an output directional dependency graph. In this way, in a CT application, more than 1-bit of data may be communicated per analog signal, allowing more data to be communicated faster. Once either precharge node is discharged, the output state of the register remains fixed until the next rising clock edge independent of changes of the input data node. Then upon receiving an instruction for writing a content onto an external recording medium, the terminal device creates preference information based on the history information having been collected therein.
