In this article we show how KD Tree works and how Voronoi diagram are linked with it by answering a simple question: given a set of reference points (points of interests), find for any point (location) the closet points wrt…
This post shows how to remove password protection on Excel files without having the need to install specific tools, you just need an ZIP reader and a notepad.
This post shows how to derive Acid/Base Partition functions using analytical chemistry and conversely how to determine pH of a mixture of poly-acid with given initial concentrations and pKa.
In this post we show how an integral can be computed using Monte-Carlo method and how combination with bootstrapping can increase precision. Reference Lets say we wan to integrate the cardinal sinus over the interval . Graphically it is about…
This post shows how to use shapely library to solve complex geometry problems easily.
This post shows how to solve the Ballistic problem with Drag Force taken into account.
This post shows how to create an animated double pendulum with scipy and matplotlib.
Sometimes, it is just fun to do some simple math and get nice figure, why not drawing some bifurcation diagrams.
This post shows of to fit an arbitrary number of Lorentzian peaks (Cauchy distribution) using scipy.
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…
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…
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…
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.…
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…
When building API with Django, Django Rest Framework is generally a good choice. If you need to extend the requirements to support GIS query then you will probably find the extension DRF-GIS convenient as it nicely fill the gap for…
