Personal Information

I am a rising junior at Harding University in Searcy, Arkansas. I am working toward my B.S. in Mathematics and Computer Science, and will hopefully continue my education in mathematics.


Goals for Summer

  • Learn Fourier Transform (in particular the Discrete Fourier Transform)
  • Be able to program in MatLab
  • Create functions to perform the Fourier Transform and Inverse Fourier Transform
  • Be able to test these functions with simulated data
  • Integrate my work with Shelby's work
  • Potentially, be able to take real data and work with it


Week One

Tuesday, May 29

  • Orientation
  • All the necessarily paperwork was filled out
  • Tour of the campus
  • Met mentor and other REU students

Wednesday, May 30

  • Library meeting, where the library and some of its resources were shown
  • Met with mentor, Dr. Rowe, about what the next few weeks I would be working on
  • At this time, I received his book on the Fourier Transform
  • Brushed up on any previous math that I thought would be helpful
  • Began to get a basic overview of Fourier Transformations
  • Read the Preface of the book

Thursday, May 31

  • Began to work through Dr. Rowe's book on the Fourier Transform
  • Meeting on Good Research Practice by Dr. Factor
  • Attempted to familiarize myself with Matlab
  • Continued working through the Fourier Transform book
  • Began some problems on the Fourier Series (Chapter One)

Friday, June 1

  • Spent the day working on teaching myself about Fourier Transformation which consisted off:
    • Worked on the problems on the Fourier Series (Chapter One)
    • Taking notes and doing the problems on the Continuous Fourier Transformation (Chapter Two)
    • I also looked up additional problems and examples online to ensure that I understood what I was doing


Week Two

Monday, June 4

  • Spent the day further working on the Fourier Transformation which included:
    • Taking notes and doing the problems for Chapter Three of the book "Specific Fourier Transform Pairs"
    • Taking notes and doing the problems for Chapter Four of the book "Continuous Fourier Transform Properties"
    • Looked up more information on convolution and correlation

Tuesday, June 5

  • Spent the day working through the Fourier Transformation book:
    • Finished up a few problems from Chapter Four
    • Finished taking notes of Chapter Five "2/3D Fourier Transform"
    • Finished the problems for Chapter Five

Wednesday, June 6

  • Spent the morning working with MatLab attempting to become more familiar with it
  • The afternoon I worked on more of the Fourier book:
    • Took notes on Chapter Six Discrete Sampling
    • Finished the problems for Chapter Six

Thursday, June 7

  • Began taking notes on Chapter Seven "Discrete Fourier Transform"
  • Attended the working lunch with the other REU students
  • Met with my mentor, Dr. Rowe, to further discuss our Goals and Milestones
  • Finished taking notes on Chapter Seven

Friday, June 8

  • Because the Discrete Fourier Transform is very important, I spent the day focused on it
    • Working on problems from the book (Chapter Seven)
    • Looking up additional problems and examples to gain more understanding


Week Three

Monday, June 11

  • Continued to look at the one dimensional finite discrete Fourier transform
  • Began to take notes on Chapter 8 about two and three dimensions
  • I used both problems from the book, as well as additional problems on line

Tuesday, June 12

  • Looked through several books about Matlab
  • Continued to familiarize myself with it
  • Began working on a function that would perform a 1D finite discrete Fourier transform

Wednesday, June 13

  • Took time to explore the Memorial Library a little
  • Continued taking notes on Chapter 8, focusing on the properties of 2/3D Fourier Transforms
  • Looked through a book on MatLab

Thursday, June 14

  • Worked on MatLab
  • Finished working on the function I started working with on Tuesday
    • This function would sample a continuous function and then perform the finite discrete Fourier transform
  • Finished working on a function that is given sampled data (sampled at a consistent rate) and performs the Fourier transform on it
  • Then I went back and had both functions compute the magnitude and phase
  • The phase part is having a little trouble, and will need to be fixed, otherwise the 1D Fourier Transforms functions are done
  • I also did a sample graph of the original function, the real part of the Fourier Transform, the imaginary part, the magnitude and the phase

Friday, June 15

  • Continued to work with MatLab, specifically with graphics
  • Looked through the books on MatLab
  • Began to look into colormaps a little bit more


Week Four

Monday, June 18

  • Continued trying to learn more about MatLab
  • Attempted at first to look into two dimensional graphing
  • Became distracted with colormapping
  • Loaded an image and looked into changing its format
  • Performed first two dimensional fourier transform (using the preset fft2 function unfortunately)
  • Used this information to graph the real and imaginary parts of the image
  • Then performed the fourier transform on the already transformed image and got the original image (with slight scaling changes)

Tuesday, June 19

  • Created a two dimensional sampling function
  • Tested the function on several images
  • Created a two dimensional fourier transform function
  • Tested the function on several images
  • Created a two dimensional inverse fourier transform function to further test the other function
  • Tested the function on several images
