Bartos, Control Engineering , and John Lewis, Design News . Two pages of additional results and analysis from Frank Bartos also appear starting on p. 41 of this issue of CE . Each of these two articles, along with analysis from editors and other industry experts, is based on reader research conducted by Cahners Research, and was fully independent of the supplement's sponsors. Other articles in the supplement, following the introduction, should have been labeled as "Advertorial."
