Hello and welcome! I am Jabir Rahman, a graduate (Masters Degree) student at the University of Memphis and studying Geophysics here. From fall 2017 I have been working as a Graduate Research Assistant at The Center for Earthquake Research and Information (CERI) . For my research I am working with Dr. Chris Cramer, Dr. Eric Daub, and Dr. Charles Langston on "Depth to Bedrock and Shear Wave Velocity Determination in Ste. Genevieve, MO". A description of my research can be accessed through the proposal link below.

I am passionate about data analysis and machine learning and have been exploring ways to apply these techniques in my research. Some of my codes that I wrote for different projects or courses can be accessed here.


MS Thesis Proposal (pdf)

MASW_Dispersion

Fig: Dispersion of Rayleigh Wave Analysis Using MASW Technique from The Ste. Genevieve Project for my M.S. Thesis

Undergraduate Thesis "Economic Feasibility Study of EOR-CO2 Technique at Haripur Oil Field". (Abstract_pdf)

NPI     BreakEvenPoint          BEPafterMCS

Figure: First figure shows the result of production data analysis using normalized pressure integral method, second one shows the break even point for present data, and the third one shows the break even point determined using Monte Carlo Simulation


Machine Learning

Python: This python script is written aiming to suggest a movie for a user from a large data set using Collaborative Filtering Algorithm. The final result will be the predicted score for a given movie name, and the recommendation of a top scored movie for a given user. (python_script)

Figure: A sample output from the script showing the score for a given movie name and the recommended movie name for a given user

Matlab
: This matlab script is written to experiment the perceptron weight learning rule. (data1, data2), (function1, function2, function3, script1, script2)

Data Analysis Projects and Codes

Python:
A) A python script is written to use Newton's method to find the root of a polynomial of arbitrary order.  (code_python_one)

B) Python script make a histogram of an earthquake catalog. (code_python_two)

Matlab:
A) One- way wave equation in 1D. (solution.m) Three different ways- using loops, vectorization, and matrix multiplication.

B) Heat Equation in 2D: This script using both for loop and vetrorization methods.

Figure: First figure shows what happens to the wave when it propagates with time. The second figure shows the steady state solution to the heat equation as two separate subplots.

C) This script will load a data set from experiments looking at friction and failure in a sheared granular material in ASCII format, and will remove the material effect with time using polyfit, and detrend matlab functions, identify the time of stick-slip, identify a stick-slip event while the vibration was applied. It will also use a binary data file and will compare the result with the previous one. (main_script, remove_effect, identify_stickslip, identify_stickslip_with_vibration, second_script1, second_script2, second_script3)

Figure: The first figure shows the removal of material effect while the remaining figures show the stick-slip event progressively zooming the window.

SAC: Here, SAC is used to stack signal, rotate, and filter. (script1, script2, script3, script4)

GMT:
focal mechanism, GPS velocities for the Park field section of San Andreas Fault, and a national Seismic Hazard Map for 2% exceedance in 50 years using GMT and AWK. (script)
