Jupyter (Python) Notebooks

Here is compilation of notebooks I used for work, learning, testing ideas or having fun.

Geophysics

Numerical Modeling with Finite Differences

Cool animations inside :-D

1. Heat Difusion Equation 2D Explicit Finite Differences toy example

2. Explicit Finite Differences Scalar Wave Equation with Absorbing Boundaries (4th order space 2nd time)

3. Modeling Synthetic Reflection Seismic Survey for Geological Toy Model

4. Explicit Finite Differences Reverse Time Migration for (Pos-stack) Zero-Offset Sections acoustic (4th order space 2nd time) toy example. Forward and reverse modeling is done.

5. Analytic Solution for Scalar Wave Equation 2D based on Alford 1974 paper for evaluating accuracy of explicit finite diferences wave solution

6. Anisotropic Elastic Wave Equation Staggered Grid 2D Needs a small fix: the last animation is not for pressure field but for particle velocity in x direction.

More cool geophysics here.

Unfortunately some of the code above has not been translated from Portuguese.

Hobby Financial Market

Machine Learning

1. Shortest Pytorch example (1 hidden layer NN) Learning A Logical XOR Operator

** To Do / To Finish **

• New CV and link for download.
• Remove notebooks from this repo tha are from master.
• Make public (bring to here) part of code (many things are too private) and documents in stocks repo.
