A new and distinct cultivar of Lobelia plant named Weslolav, characterized by its cascading plant habit; freely branching habit with short internodes; dense and bushy plant form; continuously and freely flowering habit; densely pubescent leaves; light lavender-colored flowers; and relatively tolerant to high temperatures. The machine control data are associated with the scan data. Each of the first joint part and the second joint part is formed in a strip shape substantially parallel to a direction of the relative displacement. In addition, a multi-step polishing process for polishing a substrate surface using at least two oxidizers in one or more polishing composition is described. To avoid a coincidence attack in which a hacker can learn the MKB and associated media key and then guess at a device key without knowing its position in the MKB, the media key is XORed with a number representing each position in the MKB, and only then encrypted with the device key corresponding to that position.
