- Jed Rothwell says: "Your method of deriving the TCal from the slope does
- not work."
-
- Under my assumption that it is a first order system, if the initial value and
- slope and the final value are known, then everything is known. Of course it
- is not a first order system. But it might be close enough that this view will
- give a check on the other measurement. My point still is that this analysis
- gave an answer closer to a null result than the claimed high power, so I am
- suspicious.
-
- Steve Finberg looked up my 1958 MS thesis where I first started working on this
- kind of computer model. Since, I have worked on the computer simulation that
- drove the centrafuge that trained Grissom, Shephard, Glenn, etc., to practice
- flying their capsule under "g" forces. Wrote code and did simulations for many
- missiles that never flew (because of the simulations). But I am not an expert.
- Most of these simulations do not work. We completely failed to get a decent
- model for the present calorimeter.
-
- But I am not so sure that an arbitrary electrochemist is an expert. Jed is
- correct in saying that transient analysis is harder than steady state. But
- now we have the FFT and can do some wonderful things. Still it is hard to get
- any model that works for an arbitrary system. That is why McKubre and myself
- work hard on the physical configuration of the calorimeter. With the right
- physical layout, it is possible to have a reasonable model. The Takahashi
- configuration is such that I don't know how to get a model, and thus don't
- believe that it can be calibrated.
-
- I now retire from the discussion, as Jed can clearly type faster than I can.
