Hello,
I'm interested in building a small non-invasive battery powered device that wraps around a pressured 1/2" pipe for measuring potable water.
From https://en.wikipedia.org/wiki/Magnetic_flow_meter
and watching youtube videos, it seems they all use electrodes which contact the liquid...
thanks, I pretty much got it in the end, but there is one thing I'm still not happy about.
Each p(k) = chance of it appearing k times * (1-chance of getting zero)
In normal trials of a flipping a coin, if you have n trials and you want to find the probability of flipping k heads then you would...
I've already had a look at the iitg.ernet set, but I don't understand the part "The following relations hold for the product form trial". What are they saying there?

The only textbook I have doesn't have the details to this. Can you show me what these linear equations look like? I have n equations (n is queue length), I can't picture what I'm going to get out of this.
Homework Statement
Consider a network of n queues with a Poisson arrival process of
parameter t from outside the network, and independent exponentially
distributed service times of parameters r1 to rn.
Customer that first arrived to the network initially join queue i with
probability Pi...
Hello,
I've been looking at the derivation of the exponential function, here
http://www.statlect.com/ucdexp1.htm
amongst other places, but I don't get how, why or what the o(delta t) really does. How does it help?
It's really confusing me, and all the literature I've looked at just...

All good upto here
I feel like a complete incompetent.
p-n=X. So we set p = 0. n = -X. Ok the first bit makes sense but I don't understand how I can "note" -X = |X| > 0. You're saying that -X is the same as |X| (when the modulus of X is greater than 0 (aka X is not zero)).
Maybe you already...
Thanks for the help,
But I'm not making the mental link
So far I know we can write |a-2b| as 2 inequalities
y ≥ a-2b and y ≥ 2b - a
But I don't see how the equation
yp - yn = a - 2b
comes about, nor why we then go onto maximise yp+yn
Thanks
Thomas
So basically yp - yn = 5 is a constraint
along with yp, yn >= 0.
my objective function is yp+yn
But how does a - 2b = 5 fit in here? What is the translate between y+ and y- and a and b?
Thanks
Thomas
