About Me

My name is Jack Weisse. I will be a senior in the School of Arts and Sciences at Marquette University in the Fall of 2009. I am currently working with Dr. Scott on Ergodicity for Lagrangian Assimilation.

Research

May 18

• Met with Dr. Spiller about REU project
• Began background reading

May 25

• Read Ch 12.1 on flows provided by Dr. Scott
• Read important sections of "A Bayesian approach to Langrangian data assimilation"
  • Looked at how Fig 1 was produced
• Read important sections of "Capturing Deviation from Ergodicity at Different Scales"
• Skimmed over A First Course in Differential Equations with Applications by Dennis G. Zill for basic background on differential equations

June 1

• Met with Dr. Scott about REU project
  • Discussed how and what to put into code
• Went through online tutorial of MATLAB in order to write code
• Began writing code to test ergodicity in a simple system

June 8

• Finished first draft of ergodicity code
• Met with Dr. Scott to review code and talk about what to do next
• Began updating code to include new parameters

June 15

• Finished second draft of code
• Met with Dr. Scott to review code and talk about what to do next
• Began updating code to compute space average and time average

June 22

• Ran into some problems with translating theory to code
  • Met with Dr. Scott to discuss
• Finished updating code and met with Dr. Scott to review
• Began writing code to imitate integral in ergodicity equation

June 29

• Continued to write code to imitate integral in ergodicity equation
  • Had some trouble with translating theory to code
• Attended REU lunch on Thursday July 2
  • Gave brief presentation on research

July 6

• Revised code to include comments, timer, and a faster runtime
• Plotted d vs. s for each run
• Began writing code for torus, 2D model of previous code
  • Began writing code for Box Exchange map

July 13

• Had bugs with box exchange map - moved to invariant circles map
• Had bug with code

July 20

• Continued struggle with bug
• Bug resolved, printed graph for invariant circles map
• Programmed Nonergodic Island map using different seeding technique
  • Had slight bug, quickly resolved, printed graphs for both maps

July 27

• Began collaborating with Dr. Spiller and Gabe Van Eyck
• Began programming shallow water equations using runge kutta method

August 3

• Continued programming shallow water equations
  • Recreated flow field figure in Lagrangian Assimilation paper
• Began discussing how to implement ergodicity defect code on shallow water equations

August 10

• On Vacation

August 17

• Poster week

August 24

• Poster presentation on Tuesday, Aug 25th
