Indeed! Much appreciated. Cheers, Mike.

Thanks Aleph. Figured this much out; missed out on the primes... Kp + (Ki T z)/(z - 1) + (Kd (z - 1))/(T z) = (Kd - 2*Kd*z - Kp*T*z + Kd*z^2 + Kp*T*z^2 + Ki*T^2*z^2)/(T*(-1 + z)*z) Collecting z's gives: Kd/T + ((-2 Kd - Kp T) z)/T + ((Kd + Kp T + Ki T^2) z^2)/T Therefore, K_D = K_D'/T; K_I...

How does one go from the simple substitution to the end result? \dfrac{U(z)}{E(z)}=K'_P+\dfrac{K'_ITz}{z-1}+\dfrac{K'_D(z-1)}{Tz}=\dfrac{K_Pz^2+K_Iz+K_D}{z(z-1)} Found the above simplification in http://www.nt.ntnu.no/users/skoge/prost/proceedings/acc04/Papers/0008_WeA02.5.pdf" in Eq 23-24...

I found some s-function alternatives; you can find the code here: https://gist.github.com/978493 I tried to simulate the first one (same as the last) in SIMULINK, but got a rather strange "flag==3 call must be a real vector of length 1" ?

As made apparent by the high-level system diagram (available via the link above) the purpose here is to simulate an omni-directional robot in MATLAB. Those assisting will be credited in the journal paper that is currently being written. Here are some further points to consider: (A) The first...

Hi! I've been looking to simulate a PI controller in SIMULINK without much success. You will be able to find a description of the above in the images located here: https://picasaweb.google.com/102197309611185157885/PIControlWithMatlabAndSIMULINK?authkey=Gv1sRgCOCnzvbm5PuNJA&feat=directlink. I...

Well, PE is C_2H_4, repeating 'n' units. I guess, you're right in terms of there being no possible reaction with HCL...

Hi, Would be interested to know why HCL cannot eat through LDPE for example. Thanks, Mike.

Is Qc the same as heat of combustion? This page lists a HHV value for diesel of 44.8 MJ/kg; considering the equation I've seen uses 42.5 MJ/kg, it explains the 10^6 factor! You're right; I did look up some books and found equations in terms of work per cycle/volume displaced. It was an...

I have split the variables above into two sections: (1) the variables I have figured out and are certain of and (2) the variables that continue to elude me. The two driving me up the wall are q_C and \epsilon_{\text{Vi}}. Really would be glad if someone could help. Thanks!

Hi, I have been reading some online papers and have been struggling with the following equation as the author seems to introduce it without much detail. Since my background is primarily in electronic engineering, it is quite possible that this could be one of the elementary equations in...

Thanks Fatra :)

Fatra, I was looking at the information http://books.google.com/books?id=aMzuEby4fX4C&lpg=PP1&dq=nuclear%20physics&pg=PA148#v=onepage&q=&f=false". You can see how they have described it there. Would you be able to give me the completely correct, combined equation? Would it be...

Thank you Fatra. I have just referred up the same book and did indeed find the listing of 1.176 MeV under Cs-137. Referring another source I can see how the end-point energy is far greater than E_{\text{max}}=1.176 \text{MeV}. I should have in fact set my original equation out as...

Thanks for your reply Fatra. Would you be able to let me know why I seem to be achieving a correct result (following the calculation for estimating decay energy) for \beta^--decay of Tritium, but not for Caesium? In the same application for Caesium, how come I am computing closer to 3.9 MeV...
