ECE 538 Assignment 8

Your submission should follow our general guidelines. Please follow object-oriented principles. Include an executable jar file for each program.

  1. Extend your circuit analysis program to handle multiple voltages sources, such as the example below, and calculate the unknown node values. Display your results in a TextArea and use a MenuBar as in the previous assignment. Format your node variables to distinguish voltages from currents. In the example, there are four nodes and two voltage sources, so the matrix is 6 x 6 and the node values would be:
    V(1) = ***
    V(2) = ***
    V(3) = ***
    V(4) = ***
    I(1) = ***
    I(2) = ***

    R1 1 2 100
    R2 3 4 400
    R3 2 0 500
    R4 4 0 200
    VA 1 0 9
    VB 3 2 5
    

  2. Modify your earilier image display programs so that you can use a growbox to do the equivalent of imcrop in MATLAB. Your program should write out the cropped image to an output image file.

  3. Modify the bouncing balls program so that you can control the coefficient of restitution with a GUI item in the North or South position of the border layout.

  4. Improve your robot controller from asgn07 (if necessary) and incorporate it into game1. The goal of the game is to steer the robot to the yellow X as quickly as possible. Incorporate your “bread-crumbs” method to document your route to the destination.

  5. Write a Java program to perform Opening and Closing a binary image. See morph for examples of dilation and erosion on a binary image.

  6. Implement the Runge-Kutta method for solving a system of differential equations in Java. See MATLAB notes on numerical solutions of differential equations. Download MATLAB code from integrator.zip. Remember that Java, unlike MATLAB, does not use matrices as basic components so you may need Jama.
