This is not homework but I would consider it to fall in this category. I am working on a robotics project and wanted to simulate a PID controller before implementation. I need to find a transfer function for my motor for this to work.
Homework Statement
As mentioned above, I need to find...

Hey everyone, I'm trying to teach myself C++ and I recalled that a few years ago my Comp Sci major buddy of mine did a sudoku solving program as a project for a class so I decided to tackle it on my own. I'm getting some headway, but I'm having trouble figuring out a way to "brute force"...
Homework Statement
Determine the region of analyticity of ln|z| + i*arg(z) and justify your answer.
Homework Equations
The Attempt at a Solution
I said that if z=x+iy, the function has a singularity when both x and y are equal to 0 since ln(0) is undefined and arg(z) = arg(x+iy) =...
Before I get into the question I'd just like to state that this is not homework, but questions in my book that I'm going through to prepare myself for the midterm in one week. I got stuck at a few questions, here's the first one. I won't ask the next until I'm done with this and so forth...
Hey everyone.
So I like to have electronics projects going on to keep me on my toes during the academic year and my project I chose for fall ended up being a Cockroft Walton Generator. Basically, I was just looking to make a simple negative ion generator from it. I finally got the parts in...
Homework Statement
Assume the vector function A = ax(3x^{2}2y^{2})-ax(x^{3}y^{2})
a) Find \ointA\cdotdl around the triangular contour shown in Fig. 2-36 [it is a triangle with base and height of one on the x and y axis. the curl travels so that the normal vector is in the -z direction]
b)...
Hey guys, I'm working on a little project and I need to build an inductor. Now the problem is I have bare copper wire (like, a ton of it) and was hoping there was a way that I could insulate it so I could use it like typical magnet wire? Is it possible for me to just use a spray-enamel? I...
Homework Statement
I need to optimize this given code:
/* A struct used to compute averaged pixel value */
typedef struct {
int red;
int green;
int blue;
int num;
} pixel_sum;
/* Compute min and max of two integers, respectively */
static int min(int a, int b) { return (a < b ...

I need to optimize this given code that rotates an image 90 degrees so it runs at least three times faster:
void naive_rotate(int dim, pixel *src, pixel *dst)
{
int i, j;
for (i = 0; i < dim; i++)
for (j = 0; j < dim; j++)
dst[RIDX(dim-1-j, i, dim)] =...

int right;
} b_struct;
void test(int i, b_struct *bp)
{
int n = bp->left + bp->right...

The Attempt at a Solution
I called the bottom left Loop I1, the bottom right I2 and the top I3. All currents are flowing clockwise. From there I set up my KVL expressions for each loop:

This question has been giving my brain some trouble. I think i have the Electric Field integral calculated correctly (but I'll post that up here too just in case I'm wrong which is likely) but when I get down to finding the charge on the rod I literally am making a wild guess at the solution...
