Dear Readers, In the MathCAD.zip file included, you will find the MathCAD files of the program developed in this research. You should be able to "unzip" the file with the built-in function in Windows XP. However, if you are using an older version of Windows or other operating systems, you can also go to www.winzip.com to download the proper file for unzipping. The files, of course, require a licensed copy of MathCAD 11 or above to run properly. You can purchase one or upgrade an older version at www.mathsoft.com if you want to use the files provided. There are two core files, On-Design Cycle Analysis Core.mcd Off-Design Cycle Analysis Core.mcd that govern the other dependent modules (or subroutines) for different engine component. The explanation of the available inputs in the core files is in Appendix A of the dissertation, along with some values used for this research. The symbolic nature of MathCAD programs should allow you to quickly understand and use my files without further explanations. Should you need further assistance with the program, you can email me at ychiu@vt.edu. I will try to answer them in a timely manner. For the moment, the program included is only intended for enhancing the reading experience of my dissertation and for keeping the integrity and completeness of my work. Please contact me if you need to use the program for other purpose. Sincerely, Ya-tien Chiu ychiu@vt.edu
