Compute Acid/Base Partition functions
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.
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.
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…
Using pollution roses to highlight traffic influence at Brussel’s 11th Canal Lock
Pollution rose is a very important tool when dealing with Air Quality Monitoring, they help to understand from which wind sectors the pollution arises and when correlating pollution roses at several locations it can be used to triangulate specific sources…
Multiple adjustments of a catalytic kinetic
Model We want to model an heterogeneous reaction between Isopropanol and Raney’s Nickel which is a catalytic deshydrogenation. Reaction produces Isopropanone (acetone) and dihydrogen: For sake of simplicity we label the reaction as follow: Where is the kinetic constant of…
Adjustment of a series expansion with Python
Python and scipy package are very powerful when dealing with optimization problem. We present in this article a double optimization problem involving root find of a rational trigonometric equation and a non linear adjustment of a series expansion.
Adjustment of an integral function with Python
Python is a very convenient companion for function adjustment and scientific computing in general. We present in this article a simple problem where the scipy package is the sufficient toolbox to tackle an non linear adjustment problem involving a numerical…
