Collatz Visualizer

Collatz visualizer | Syracuse function with x=12

I was recently triggered by the Collatz conjecture – also known as the Syracuse conjecture. As I wanted to learn a few bunches of new web technologies (Bootstrap, Webpack, Chart.js), I decided to start a simple project on the Collatz theme in order to get a new experience.

The Collatz conjecture involving the Syracuse function is still an unproven mathematical problem. With my website, you can visualize the Syracuse function for a given initial number.

Mageek – an ImageJ Java Plugin

Recently, I had the opportunity to collaborate with Marcela Garita Hernandez (Senior Research Fellow at Mass Eye and Ear, Harvard Medical School) on a small Java plugin for the software Fiji (known as ImageJ, a scientific image manipulation program). The object of this collaboration was to write a piece of code to read microscope images, to transform and to save them in batch (to process multiple files in background).

Fig. 1 – Capture of Mageek v1.2.1 graphical interface,.
On the left the scanned file extensions, in the center the actual files and on the right side the options to configure the process. A status line shows vital information at the bottom.

For information, Mageek works with several microscopes and more precisely with several microscope file formats. In Fig 1. you can see 3 extensions selected: *.lif images comes from Leica, the *.czi from Zeiss and the *.nd2 are from Nikon.

Here the user choose Magenta, Red, Green and Blue LUT.

BléDD – Database on durum wheat

As a result of my DUT internship at INRA Montpellier, France (under the responsability of Patrice Buche and Luc Menut), the objective of the BléDD project was to convert tables of data from leaflets (paper and digital) into a relational database in order to allow specialists in the field to study the evolution of technological characteristics of durum wheat varieties grown in France since 1973.
