Would you believe that the guy who invented Tupperware,
I think his name was Tupper, had a patent on a boat driven
by a harnessed fish? I'm not saying it's true, just asking if
you would believe it?

Speaking of electric cars. How about a bus bar burried in the interstate
highways and major highways that cars can drag a conductor to power their
car and charge their batteries. Then when you turn off the main road you use
your batteries. A total electric vehicle. Build many nuclear power plants to
power this. No pollution, no oil imports.

Not a new idea. There are dozens of designs for powered highways.
One method involved alternating horizontal plates, activated when
a car is detected above them. Two contactors mounted front/rear
on the car would be spaced so that they would make contact with
the appropriate set of plates. Another popular version used buried
electromagnetic coils. Some versions have the conductors left/right
instead of front/back. All of them suffer the same problems, too
costly.

Are you serious with "no pollution" with nuclear power plants?

OK, don't want to start a discussion, but I doubt that statement is valid.

It may be a bit of a surprise that a lot of you have been using "Sigma
Level" all along in a different "QualPro" quality management system. They
are related by the following identity

Sigma Level = 3 * Cpk +1.5

As a result a Cpk of 1.33 (which is very good) is equal to a Sigma Level of
5.5 (ie close to the 6 sigma level mantra)

All of the other tools and processes are similar adaptations of previously
used methods. Its simply a repackaging into one overall system.

From my perspective the best part of 6 sigma is that it forces a formal
project which by definition has a management sponsor (which means you get
resources including a "black belt" to run administrer the project and
requires a closure. Having said that various levels of bureacracy still
exist. I was involved in one where the fix was chosen, designed, built,
installed and started up before the project got through the analyses phase
because of difficulties getting representative samples/data. Six Sigma can't
solve all problems.

You don't say what type of prototype development house you need. Is
this for circuit board stuffing/reflow? Or perhaps a bare board
fabricator? or even perhaps a design house?

There are so many types of places out there, it's hard to help without
that information :)

Let us know

Turmel came to mind when I was watching "The Princess Bride" the other
night.

Turmel kept using the term "Krieger Quash".

I don't think that term meant what Turmel thought it did.

Turmel reportedly presented no evidence that any of his customers used pot
for medical purposes.

Would a doctor be permitted to use the 'medical marijuana' defense for his
own recreational use?

JCT: This is the Ray Turmel cultivation charge that arose before

the Krieger ruling in 2002 abrogated Section 7(1) of the CDSA.

This is not the John Turmel cases.

The Malmo-Levine case says the doctor can't claim recreational use.
The Turmel case says the doctor can claim for medical prevention use.
If using marijuana to prevent epilepsy and all those other nasty
illnesses is his professional opinion, it would be better received
than that of a statistical engineer.

I am top posting, and I realize it. However, I'll keep my answer short.

I can't answer the implications below, as the political implications and the
possible "thin skinned" objections involved seriously imply that there is a
personality conflict somewhere. However, I can say the following: I have a
master's degree in chemical engineering, and until 1994 (with my
father-in-law's passing), I had a tenured math professor in my immediate
family. I am of the opinion that I have somewhat of a math background, but
nowhere near what my father-in-law had. Comparing the math background of an
engineer to that of a mathematician is a silly thing to do. Engineers have
enough math background to solve most problems that they will run across in
the real world, but nowhere near the math background of someone who majored
in mathematics. In other words, this is the same as assuming that a
generalist has a background that is "somewhat equivalent" to a specialist.

I am the department chair of Math & Engineering at a community college.
Because I am an engineer (BS Physics, MS and PhD Mechanical
Engineering) I was told the following by an anonymous math professor in
the department:

====================================================
The department his [sic] mainly a service department for math courses.
Our depoertment [sic] chair does not have a math degree or math
background.
====================================================


I took great offense at this, and referred it as "silly". Several
members said there were no silly comments. One who said that was the
other engineering professor, one who is working on his PhD (he started
in 1986!). I sent him this:

====================================================
D___,

I know that you have, by now, had a chance to see the IDEA survey
results posted on Blackboard. I wonder if, after having done so, you
still believe none of the comments were silly. You, of all people,
must see the comment that I have no math background as silly. I
imagine you have a math background similar to mine as you approach the
end of your PhD work. You don't find that comment disrespectful of
everyone with graduate degrees in engineering, yourself included?

It was a silly comment. Maybe you'd choose a different, perhaps more
tactful word, but I just can't come up with any better word for it.

K___
====================================================


He replied with this (which he kindly cc:ed to the Dean...). I'd like
to know what others in this newsgroup think about his statements:

====================================================
K___,

Once again you miss the big picture. As an engineer I have an
engineering background but do not profess to have a math background.
There is a major difference between having a math background and having
taken math courses as part of a different major. As an engineer I use
math as a tool not as a science. I do not have the same insight into
math as a science as would a mathematician. My uses and therefore my
interpretation of math are quite different from my math colleagues. I
do not have the same appreciation of a compact proof or a unique
solution to an obscure problem. As an engineer I tend to prize
numerical methods over direct solution techniques. As an engineer I
tend to look toward application rather than theory. As an engineer I
tend to take for granted an understanding of basic mathematical
operations and techniques which many of my math colleagues spend their
careers teaching in our service courses. If you look further at the
comment from which this "math background" statement comes, you will see
that it refers to the service area of our department. I have taught
Essentials and Tech Math over the years and know the time and effort
that goes into teaching those courses. I admire those who are able to
do it on a regular basis. It is because of their math backgrounds that
they are able to present this material successfully at a level suitable
to their audience.

Since you bring my PhD work into the discussion I would have to say
that in spite of this advanced degree work I would still not say that I
have a math background. It would be like me saying that since I am
conversant in several computer languages, because of my engineering
degrees, I have a computer science background; I think D___ would tend
to disagree with that. I also don't think that D___, in spite of his
PhD, would claim that he has a math background [the PhD to which he
refers is in Ed Psych]. If we are using the PhD as a comparison I
would look to M___ whose math background gives him a much different
approach and insight to math than mine in engineering [this doctorate
is a Dr. of Arts in Rhetoric of Mathematics].

As an engineer I find no disrespect in the comment, I don't find it
silly, I think it is accurate.

D___
====================================================


I think he should read this to his thesis defense committee (if he ever
gets that far...) before he defends, just to set the record straight
for them.

It's normal for cats to scratch their ears occasionally. If they do it
a lot or shake their heads a lot, they may have ear mites, which can
cause a lot of damage as well as distress if they get out of control.

Now I was wondering since modern solutions use alot of electrical
control on animals such as the mouse noise maker of ultrasounds. And
the dog fences of electronic yard perimeter. So I am thinking that
perhaps cat ear mites may be sensitive to electronic frequencies that
is harmless to cats themselves. So that one can install a device at the
feeding station of a cat and the electronic pulses force the ear mites
to vacate the cat.

So I wonder if anyone has tried electronics as a means of removing ear
mites.

Perhaps there is a radiation that even kills the mites but leaves the
cats and humans unharmed.

Not let me make alot of further suppositions. Suppose there is a
electronic frequency that forces ear mites to vacate cats. Then suppose
there is a specific frequency that fleas simply cannot tolerate. Then
we can invent a flea remover of a electronic lamp that we place the dog
or cat for overnight and the fleas just want to vacate.

But going further, suppose there is a frequency which mosquitoes cannot
tolerate and which biting flies cannot tolerate. Then I envision some
smart clothing that has installed a electronic device that is battery
operated, or even bodily implanted like a heart pacemaker. And that any
mosquito when it comes close or nearby to the electronic beeper simply
is repelled from getting any closer.

Just as the ultrasound beepers that keep mouse out of a building, I am
thinking that some electronic frequency keeps mosquitoes permanently
away.

I often wear bug netting outdoors. People who see me in summer think I
am a bee-keeper. I tell them I am a mosquito-shoo-awayer, not a
bee-keeper. But suppose electronics can repell mosquitoes and biting
flies so that one can install that into a fabric such as the bug netted
clothing where the electronic beep of a battery operated beeper runs
the length of the netted clothing and thus whenever any bug lands on
the clothing is repelled by the electronic frequency.

The number of factors I have is variable
The number of levels for each factor is variable
I want to determine main effects and 2-factor interactions
I need a resolution V design array

Currently, I am using the IPO (In Parameter Order) test generation
method. I believe that this method is not giving me enough degrees of
freedom in the design array. I am using the IPO method to perform
horizontal growth and then vertical growth for every factor. It
guarantees that all pairs will appear once in the design array. The
problem with this method is that main effects are being aliased with
2-factor effects.

Any help you can provide will be greatly appreciated.

Thanks!

I expect you have already looked over NIST's Engineering Stats

Yes, I have looked over that site. Thanks for your suggestion. To
clarify my problem: I am using categorical factors; I am looking for a
solution that I can implement programmatically; and I want to create a
generalized solution that can handle any number of factors with any
number of levels.
