Subject: MBTI - is it valid and where is it applicable?
Date: 13 Nov 92 01:27:05 GMT
Organization: NASA Ames Research Center

I recently took the Myers-Briggs Type Indicator through my school and
was wondering you useful the information it supposedly provides is.  I
have been told that it should be able to indicate major and career
avenues as well as explain an individual's interpersonal relations.  Are
there other tests similar to this?  Could employers use these in
evaluating future employees in terms of appropriateness for a given
position?  
I came out as an INTP.  Could anyone out there give me an idea what this
indicates, in general if not in specific.  
Are there any similar "tests" which are modeled on things like the
Kolberg stages of cognitive development?  Is this vastly different or
are they related in any way?  Doed the MBTI have a sense of progression,
like various other stages of development (i.e. Erickson's psychosocial
stages), or is it something else entirely?  I'm having difficulty
visualizing the model this test is presenting...
If anyone has a response, please e-mail me:  kyrsten@eos.arc.nasa.gov

I'm sure that it's possible to contain some fluid at 100,000 psi.
I'm not sure that air is still a gas at 100,000 psi, though.
I would have to look into the matter.  It's been too long
since I had thermodynamics.

In any case, such a vehicle would probably need a very long
hose, to connect it to a supply of high-pressure air.
I doubt that it could carry a tank large enough to give it
acceptable range.  I suppose that it might carry
some combustible material that could be burned inside
a tank, to create the high pressures.  Maybe gasoline....  Hmm.... ;-)

Your friend describes well what is wrong with big companies in

companies can't afford the political bovine excrement that smothers

I would say that, though there are fewer small companies with this problem,
there still are some.  Some that have it quite bad, in fact.

I completely agree. Even though it may seem harmless enough, relying on the op amp
to shield you from a freak electrical event is not a good thing.  If you're just
tinkering, I would suggest consulting some texts in your local library ( a lot of
schools use biomed instrumentations by a fellow named Webster, sorry, can't remember
the first name off hand ).  They might bring you up to par on some of the conventional
practices for biomed instrumentation.  Also, for the tinkerer on a college budget,
I would suggest looking into optical isolation.  You should be able to construct
a nice BATTERY POWERED front end that has an opto-isolated output to run into your
SoundBlaster.  Radio-Electronics, Circuit Cellular Ink, etc., occasionally highlight
"biomedical" oriented designs that use similar isolation techniques.  But Never,
Never, NEVER, tie yourself directly into a line powered device without reliable
isolation, no matter how safe it might appear.

An important consideration here is the risk of electrocution.  It is not
accepted engineering practice to put a low impedance electrode on the human
body, and hardwire it to line-powered equipment.  A power line short in the
computer, combined with a grounded subject can lead to instant death.  You need
to use an isolation amplifier between the subject and the computer.   One
method would be to use a Burr-Brown INA101 with battery power for the amplifier,
and an isolation amp between the amplifier and the computer.  See the Burr-Brown
data book for applications.  A 741 is too noisy, and has too high a bias current
for biomedical applications.

 I am just getting into the field of biomedical engineering and I've
been doing some reading/tinkering.  At the moment, I'm interested in
EMG signals and interfacing with microcomputers.  Could someone lead
me on the right track?  What I've been trying to do is amplify signals
from an electrode with the 741 op amp (differential mode) and run the
signal into a Soundblaster card (commercial audio ADC card). Is it 
possible for this to work? I've also been writing some software
for the "interface" (games, menu programs, toys). Since I haven't been
able to get it working, I'm not sure wether it is worth it to pursue.
Could someone tell me how accurate/distinct EMG signals are and does it
take a lot of adjusting to obtain a clear signal?

P.S. I haven't any filters in the circuit.  I was hoping to be able
to eliminate noise through software.  Is it necessary to have 
hardware filters?

I'm looking into the concept of running an automobile off of compressed air.

According to my calculations (based on a Gast airmotor catalogue), such a

Is that at all possible?

Here are some rough calculations I did.  Using the equation for wall
thickness (ASME Boiler and Pressure Vessel Code)

    t_m = ____ P*D_____               from Perry, 5th ed, 6-42             
          2*(S*E + P*Y)

    t_m  wall thickness

    P = 100 000 psi         pressure
    D = 12 inch             conceivable vessel diameter
    S = 20 000 psi          typical allowable stress for steels
    E = 1.0                 weld joint factor
    Y = 0.4                 coefficient for ductile, ferrous metals

Plug in the numbers and you get t_m = 10 inch.

Not possible.  Sorry.

	I have to disagree with you. It was the CRC which answered your
question (albeit indirectly). The computer only helped you to communicate.
In my opinion, if you can find the answer yourself you should do that
without asking the net. Imagine what would happen to net traffic if every
small query (for some data available in Handbooks) is posted.

Why do you think that a vessel of 12" ID cannot have a wall thickness
of 10" ?
I think that the major problem would be to compress the air to a 
pressure of 100 000 psi unless you store liauified air and then heat
it.  I wonder if this is going to be used as a rocket.

Well, I didn't explain things properly.  That was a 12 inch _OD_, not ID.
Also, that particular equation is only valid for thin wall vessels.
I don't have the correct equations for thick wall vessels.  Even if one 
was ALLOWED to build such a tank it would weigh about 3600 kg (1 m long,
12" ID, 10" wall thickness).  I don't think it is feasible.
