REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn. Since then, many scientists from all over the world have contributed to its development. REDUCE has a long and distinguished place in the...

PY-Nodes is a Python 3 based code designed for searching nodes (bands-degenerate points) associated with two or more bands in a given material using the first-principle approach. This code is helpful in efficient searching of the nodes present in the topological semimetals such as- Weyl semimetals, Dirac semimetals & nodal-line semimetals. The code is presently interfaced with the WIEN2k package. The algorithm of the code is based on the Nelder-Mead’s function-minimization approach. The code minimizes the function f(k), which is defined as sum of the absolute energy difference of the adjacent pairs of bands at a given k-point. ...

PC1Dmod is an updated version of the popular solar cell simulation tool PC1D: https://sourceforge.net/projects/pc1d/ PC1Dmod extends PC1D by (i) including Fermi–Dirac statistics, which can be relevant in regions of high doping, and (ii) adding advanced c-Si models for Auger recombination, band-gap narrowing, carrier mobility, band structure and more. On this page you can now download the executables with all necessary extra files and documentation (now set as the default download), as well as the source code. ...

cmd-PC1D 5.9 is a command-line version of the popular solar cell simulation tool PC1D: https://sourceforge.net/projects/pc1d/ cmd-PC1D 6.0 extends PC1D by (i) including Fermi–Dirac statistics, which can be relevant in regions of high doping, and (ii) adding state-of-the-art models for c-Si models. cmd-PC1D adds flexibility through implementing the calculations in a scripting environment. The source code for later versions with more updates on the device physics can be found in the PC1Dmod page (version 6.2 can be compiled both as the command line and GUI version): https://sourceforge.net/projects/pc1dmod/ The executables and some documentation can can be downloaded from PV Lighthouse: https://www2.pvlighthouse.com.au/resources/PC1D/PC1Dmod6/PC1Dmod6.aspx Authors: Halvard Haug and Birger Retterstøl Olaisen Institute for Energy Technology, Kjeller, Norway

Dirac is a general-purpose video codec aimed at resolutions from QCIF (176x144) to HDTV (1920x1080) progressive or interlaced. It uses wavelets, motion compensation and arithmetic coding and aims to be competitive with other state of the art codecs.

PentaCloud is currently a KHTML-based web rendering engine with the integrated ability to play HTML5 video and audio using the built-in Dirac and FLAC software codecs respectively. PentaCloud as a web layout engine may not be the final decision.

RHydrogen is a lightweight open-source c++ program which solves the Dirac equation for Hydrogen-like atoms. This implementation is based on the ROOT program library.

Schrodinger is a project implementing the Dirac video codec in ANSI C code. It is meant to be highly optimized and portable. Schrodinger is developed as a joint effort between the BBC and Fluendo.
