Coy, John J. et. al. (December 2012)

  • Sampled graphic illustrations from his NASA Reference Publication “Gearing” (1152), showing different types of gear trains for inclusion in the Simple Machines section of the Physics chapter. This NASA document, being a US government publication unclassified and approved for “unlimited” distribution, lies within the public domain and so may be freely sampled into other works such as this one.

Dennis, Japheth (2011-2012 academic year)

  • Suggested additional examples of PID controller responses to graph, to help illustrate the unique features of each action.

Faydor, L. Litvin et. al. (December 2012)

  • Sampled 5-planet planetary gear set illustration from his NASA publication “New Design and Improvement of Planetary Gear Trains”, for inclusion in the Simple Machines section of the Physics chapter. This NASA document, being a US government publication unclassified and approved for “unlimited” distribution, lies within the public domain and so may be freely sampled into other works such as this one. Also sampled helicopter transmission gear set illustration from his NASA publication “Handbook on Face Gear Drives With a Spur Involute Pinion”.

Goertz, Kevin (2006-2007 academic year)

  • Took photographs of various flowmeters, control valves, and an insertion pH probe assembly.

Larsen, Dayn (April 2018)

  • Identified typographical errors in the (Digital Data Acquisition and Networks chapter).

Marshall, Travis (2012-2013 academic year)

  • Contributed analogy of a “shadow” to the explanation of absorption spectroscopy, after helping to install a laser stack gas analyzer during a summer internship and helping to explain that instrument’s operating principle to himself.

Poelma, John (2010-2011 academic year)

  • Took photographs of various pressure vessels, instruments, control valves, and other process hardware at NASA’s Stennis Space Center in Mississippi.

Toner, Aaron (August 2012)

  • Took photographs of his self-constructed MicroLogix 1100 / C-More Micro PLC trainer for inclusion in this book.
