Lawnmower gas tank

I just read the article "Back to Basics: How Gain Scheduling Works" in the January 2011 Control Engineering magazine.   I thought I’d add this somewhat humorous observation: this article could be subtitled, “Why Do I Always Spill Gas When I Fill the Tank on the Lawnmower?”

Annual Salary Survey

Participate in the 2013 Salary Survey

In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.

Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
