ENGR 12600 Fall 2008
HOMEWORK #12
Due: November 19  25
1. Reading Assignment
Complete the assigned reading posted on the Course Schedule on the ENGR 126 Blackboard
homepage.
2. Graph Identification
This problem to be completed individually.
For each of the following functions, write the letter of the graphs shown below that best represents
the shape of that function and the Matlab command (
plot
,
semilogy
,
semilogx
, or
loglog
)
that would generate a plot of the same function to make it appear linear. The origin of each graph
given below is in the lower left of the graph window except for Graph A. In each case, x is
independent, y is dependent, and constants K, L, V, W, g may be positive or negative.

For each of the following relationships, identify what type of relationship you would expect (linear,
exponential, etc) and draw a rough sketch of the relationship. For each, give a brief (one sentence)
explanation for your choice.
i.
The temperature of batch process aluminum, with respect to time, as it cools from 700°C
to 22°C
ii.
The volume of fluid in a tank, with respect to time, as it is filled by a pipe with uniform
flow.
iii.
The number of bacterial cells, with respect to time, in a growing colony.
iv.
Diameter of a balloon being filled with respect to volume of noncompressible gas.
v.
Distance traveled by a car, with respect to time, decelerating (braking) at a constant rate.
Deliverable: Answers to above questions.
4. Digital Image Processing
This problem to be completed as a team.
Image processing has many important uses. One critical use is the rapid processing of facial images
to identify a child who may have been taken from a parent in a theme park. In this homework, your
team will write a main program and three functions that process an image different ways, using
functions written by different members of the team.
