I did Nyquist.
Yeah you are correct. I just tried the simplified equations I posted and did another graph with functions of more complexity and both Nyquist plots are the same..
I guess I typed something in wrong :(
Thanks for the help though!
Hi,
Just a simple question on Transfer Functions.
If I was give a open loop TF, G, and a feedback loop H, then the closed loop TF is G'=\frac{G}{1+GH}.
So my first attempt was to simplify the G' by hand and then plot it in excel which produced a crescent shaped moon.
By...
It is a little more complicated than I hoped it will be. But it is good to know!
Although, I am working on an assignment which deals with something similar. I am given the concentration of 3 fissile isotopes in a CANDU core burning at a power P and asked to find the 6 delayed neutron...
That makes more sense. How would the fraction of fission function look like?
Would it be something like this:
w(U235) = \frac{0.007 * \sum_{f,U235}}{0.007 * \sum_{f,U235}+0.993 * \sum_{f,U238}}
where \sum_{f,U235}=582.6b and \sum_{f,U238}=1b
I am trying to figure out what happens to the power when a prompt jump occurs. From Nuclear Reactor Analysis by Duderstadt and Hamilton, a prompt jump approximation can be done to yield the following equation:
\frac{P_{2}}{P_{1}} = \frac{\beta-\rho_{1}}{\beta-\rho_{2}}
Now the question is...
Hello!
J(Ω) = ∫n(Ω)vΩdΩ
This is a neutron current question. It wants me to figure out the net neutron flux (and direction) through a unit area of the xy plane. It gives an equation for n(Ω) = (1/4π)(1-cosθ), but I am trying to figure out what Ω is inside the intergrand because that is...
Update: I just received offer of admission to McMaster and still waiting for UOIT. If I do receive an offer from UOIT, I am not sure which one to choose.
So if anyone has experience with the masters program at one of the two universities, please let me know how your experience was (with your...
My friend asked me why do houses have electrical sockets that output a constant voltage rather than a constant current.
For the life of me, I couldn't answer it..
Anyone help me out?
Thanks,

Hi all,
I am trying figure out this diffraction problem.
I have to find the intensity distribution of a four slit fraunhofer diffraction grating using the convolution theorem. I can do the math and all...but I do not know how to start it! The only information I am given is the slits have...
So I am suppose to solve for the transfer function of the circuit i have attached.
First I would find the V_out at the resistor. This is done by V_in=I(jwL + 1/jwC + R)
Then the transfer function is: H(f) = V_out/V_in = R/(jwL + 1/jwC + R)
Now I need to find the transfer function by...
Consider a Michelson interferometer with semi-transparent mirror with a reflection coefficient for the intensity, R and transmission of T=1-R. The mirror does not absorb anything.
Calculate the intensities of the light in the two outputs as a function of delta_x = x_2-x_1 which is the...
I see, I could exclude the 3V source from the calculation of V_d which would make it 15-12I
So now,
V_a-I_12*12k = V_d = 15-12I
12-6I - I_12*12k = 15-12I
I_12 = 0.5I-0.25
Since V_b = V_a -I_6*6k --> I_6 = 1-0.5I
then I= I_12 +I_6 = 0.75
As for I_2,
It should simply just be I_2 = V_d/2k
and I...
well i calculated I_3 as (V_c-3V)/3k = (6-3I-3)/3 = 1-I
so subbing that into V_d = V_c -3 +I_3*9k = 6-3I-3+9(1-I) = 12-12I
unless i calculated I_3 wrong?
