TSR Electrical & Electronic Engineering (EEE) Super Thread

Got my offer yesterday. A*AA

Not taking it. They pissed us about too much with the extra statement and long delays in making offers, when most other unis had already sorted out their act. Also the online booking of applicants day place was shoddy.

A*AA? Extra statement? Are you sure you applied to EEE?

Should I choose Uni of Manchester or Uni of Nottingham for EEE? What are the pros and the cons of each?

Also, is it possible to do my industrial experience year in London?

Can you visit the universities? Both are good for EEE, both have good nightlife, both are in big cities... You need to be specific with your ideal university for someone who doesn't know you to be able to help you.



Ask the universities this. It probably depends on where is available.

Well, i may be out of step here - with the current crop of students, my my feeling is that either a> you are interested in getting an education for a career that will support you (hopefully) for the rest of your working career, OR b> you want to "party, party, party till you drop". My experience in engineering school [BSEE level] was that there was practically no time for the "party" part. Realistically, it's for 4 to 5 years. I would think that most people could stick to business for that long.

I did a masters degree a few years after i graduated whilst working full time as an electrical engineer. My job involved out of town travel about 50% of the time too. For that reason, it took me 7 [believe it or not] years to complete the masters pgm [successfully]. Liberal arts candidates have time to "party, party". When they graduate (if they do), they have a degree that they may, or may not, be able to sell. Engineers [IMHO] have something that is considerably more salable, but you have to put in a fair bit more work to get it - at least i did. Part of that was that nobody had ever explained to me how to be a serious student. That was my fault. Fortunately, i figured it out whilst i was in graduate school. I'm sure that if i had NOT, i wouldn't have managed to get my masters degree. Good luck to all of us. Cheers.

Hello electrical engineers . Can someone explain to me how to find the angle of emergence to draw in a root locus hand plot?

Say I was given the overall transfer function

$\dfrac{s+5}{s^2 + 5s + 9}$

@trapking @+ polarity -

had a look at my notes, I don't know what the angle of emergence is, do you think it would be the same as the angle that the locus departs from the poles?

If so, each angle is found using: θ_i = π + arg({s+p_i}{F(s)}) where I guess F(s) would be the transfer function you posted, and your poles are s = -p_i. This formula was given, but I believe it comes from the Angle Criterion

The TF has yucky complex roots/poles (-2.5 ± 1.6583j, but i'll just use a ± bj from now on) but you can use them to factorise the denominator to give you:

$F(s) = \dfrac{s+5}{(s + a + bj)(s - a - bj)}$ (I'm not completely sure the signs are right here lol)

at this point you multiply F(s) by (s + p₁) just to cancel out one of the factorised brackets in the denominator to give:

$(s+p_{1})F(s) = \dfrac{s+5}{s - a - bj}$

Now, to find the arguments:

$arg(\dfrac{s+5}{s + a + bj}) = arg(s+5) - arg(s + a + bj)$ - I used this trick quite a lot but I can't remember where it came from

My working out took a huge tangent at this point but I think you let s = -p₁ (and do the same with p₂ to get your second angle), then to find the arguments you just do arctan(imaginary parts/real parts) and plug these back into the formula at the beginning

e: I hope someone can check this

Yeah, its the same as the angle of departure. My lecturer didn't use this argument method, but I like it a lot, thanks

What did they use?

I skipped this bit when I was doing my problem sheets because the angle of departure only seems to matter if you have complex poles.

Is there a major difference between firming UCL compared to Imperial for EEE?

Why do you want to firm UCL over Imperial?

Posted from TSR Mobile

Ive currently firmed imperial and insured ucl but im considering just withdrawing my imperial choice and having ucl as my firm

Why?

The main reason is because of ucl insurance accommodation policy so im not guaranteed a place for first year if i keep it as my insurance. Secondly I feel I'll fit in better at ucl like I am conpletely opposite to the stereotypical imperial student and id prefer to meet a range of students not just ones who do science subjects. Finally im predicted A*AA but my Imperial offer is A*A*A which I very much doubt I am going to get.

There you go: you've answered your own question.
