• In addition to the normal data gathering methods ( e . g ., balance system, pressure measuring transducers, and temperature sensing thermocouples ), state-of-the-art non-intrusive instrumentation ( e . g ., laser velocimeters and shadowgraphs ) are available to help determine flow direction and velocity in and around the lifting surfaces of models or aircraft undergoing investigation.
• In December 2001, Mark Miller writing in " The Globe & Mail " said, " It's work supported not by the majors, but by smaller companies, as small as the Uxbridge, Ont ., label Spool, which released two of the most interesting Canadian CDs of 2001, West Coast guitarist Tony Wilson's melancholic " Lowest Note " and a boisterous collaboration between trombonist / composer George Lewis and Vancouver's NOW Orchestra, " The Shadowgraph Series " ."
