Dear Mr. Nystrom:
We are in receipt of your
letter response today sent via Fax.
The best time for a luncheon
meeting and/or discussion of the content of your paper would have been before
you published your paper. Unfortunately, you went ahead with publication
without properly assuring that the contents of the paper had a solid foundation
The semantic nuances you utilized
in your paper to attempt to disassociate that your coding implementation of the
“inelastic model” as somehow separate and apart from our “McHenry model”
failed. Your paper attempts to shed doubts on the validity of the “McHenry
model”. I again reiterate that had you contacted us in relation to your
research we could have either provided an evaluation of your coding
implementation or run some tests of our model for you or possibly provided you
with a beta copy of our code. As it
stands, your paper is flawed and erroneous.
You assert that when you run
the data from our report (SAE 970960) to replicate our Figure 10 that “your
calculated results are in good agreement”. Shouldn’t this have been a clue to
you that perhaps the inputs used to create your Figure 3b demonstrated that
there are fundamental flaws in the inputs you used in
your paper for our model?
Are you are aware of the term
GIGO? The term is an acronym that if you put garbage inputs into any
computer program you can get garbage outputs. If your coding is correct then
the problem is with your inputs (e.g., Figure 3b).
Again, had you contacted us
with your questions or problems then you possibly could have avoided the many
errors and misstatements contained in your paper. As it stands, your paper is
another demonstration that the SAE “peer review process” contains serious flaws
Very truly yours,
