I was walking by one of the buildings at UIC Chicago... and it is about a 10-12 story building. on the side, near the top floor, there is a strange track outside of the building attatched to the roof but sort of protruding a bit. at the end of the building, by the "track" thing, there are doors that look similar to elevaotr doors... does anyone know what these are or what they were used for? (theyre not in service any more!)

Just want to know if two generators with same featuers are put on with same fuel filled in the tanks.
1st one is giving out 3500Watts (connected with Fridge, Tv, Aircon, Fans, Tubelights and Bulbs).
2nd one is giving out just half of it 1750Watts (Connected only Tv , Fans and Tubelights).

Which one will have the fuel finished first and why ?

I have to test a transfere fucntion with this input to use the lsim function...

Time range is define as...
t=1:10;

input function is t square divide by 11, as in (t^2)/11. How do I define this function?

when I put v=(t^2)/11, I get some error about the matrix, saying it should be square matrix... I think it has something to do with the time range but I don't know what to do

Anyone can pls help me out... thank you...
