Xournal: interface optimization
Xournal is an open-source note-taking application for GTK+/Gnome platforms. It is extremely useful with an active digitizer on a convertible notebook. To optimize the usage of screen space, I have modified the user interface slightly:
Usage: Just replace the xournal.ui which is usually found in '/usr/local/share/xournal/'. Works with the latest version of Xournal from github/dmgerman.
Hartree: find the NLSE ground state by numerical variation
A little numerical program for finding the minimizer of the 1D Hartree equation (or more precisely the Gross-Pitaevskii equation) in an external potential. You can follow an animated version of the minimization process in GNUplot. Afterwards the convergence behaviour is graphically represented (as number of random trials needed for an energy improvement).
- hartree.c (C99 source code)
Usage: Compile with 'gcc -std=c99 -g -o hartree hartree.c -lm'. Create a folder 'field'. Run './hartree'. If you cannot see the animation, check that you have gnuplot-X11 installed. Play with the sourcecode to solve different systems.
ChemEtikett: tool for printing chemical labels
With ChemEtikett Pro you can quickly print simple labels for the chemical laboratory.
- ZIP-Archiv, ca. 0.2 MB (only for Windows operating system)
ChemEtikett Online is a simplified version of ChemEtikett Pro. It can be used to create labels directly in the browser, from which they can be printed.
