	+ Home		+ Home > Publications > HITL Simulations > Real Time Simulation Documentation Technical documents pertinent to real time simulation are often requested from the Aerospace Simulation Operations Branch at NASA Ames Research Center. You can find certain documents in PDF format here. Most of these documents have been previously published by NASA; others are NASA-copyrighted “working papers.” The technology represented in these documents is generally available to users of the Vertical Motion Simulator (VMS) at NASA Ames Research Center, and instances have occurred where the aircraft industry has come to our facility with compliant models. This has been especially true where the technology resulted from applied research on simulation models provided in our partnership with the aircraft industry, notably with Boeing, Bell, and Sikorsky. This collection of technical papers was written by Richard McFarland. Please note that these documents were created with Adobe Acrobat 4.0 and are not accessible to screen readers for the visually impaired. We will make these documents screen-reader accessible as soon as possible. In the meantime, if you would like us to send you a hardcopy of the documentation, please contact Kathleen Starmer. PDF documents can only be viewed or printed using Acrobat Reader Software or the browser plug-in available free from Adobe. 1.0 Transfer Functions   1.1 On Optimizing Computations for Transition Matrices IEEE Transactions on Automatic Control, Vol. AC-23, No. 3, June 1978.
