Solving the Ballistic problem with Drag Force
This post shows how to solve the Ballistic problem with Drag Force taken into account.
Animated double pendulum
This post shows how to create an animated double pendulum with scipy and matplotlib.
Bifurcation diagram
Sometimes, it is just fun to do some simple math and get nice figure, why not drawing some bifurcation diagrams.
Fit multiple Lorentzian peaks from spectrogram
This post shows of to fit an arbitrary number of Lorentzian peaks (Cauchy distribution) using scipy.
Adjustments of a statistical distribution
This post shows how to adjust statistical distribution on a random sampled dataset and assess precision of regressed parameters. Synthetic dataset We create a synthetic dataset by sampling random values from a Log Normal law: We also create a support…
Simultaneously adjust multiple kinetics
In this post we show how we can fit simultaneously multiple kinetics from ODE system using the scipy package. That is, we will regress parameters from multiples curves described by a dynamic system at once. To reach that goal, we…
Assess GPS Altimeter dataset with Brussels Official DEM
We present in this article a quick but complete overview of the GDAL powerful capabilities using a trivial example: assessing the GPS altimeter dataset compared with respect to Brussels’ Offical Digital Elevation Model. Goals are two: showing by examples how…
From GPS to PostGIS with simplicity
This article is a simple procedure to import your GPS data into PostGIS without pain, it merely boils down to: And you are done, your layer is now a table in PostGIS database that you can query as you wish.…
Building a tree structure with a recursive query in SQL
When modeling dataset we often need to represent hierarchical relation between objects. If the information is easy to store in a classical RDBMS querying the full hierarchical structure might not be obvious at the first glance. In this article we…
