- The main goal is to create numerical programs directly from Feynman rules. It is actually developed for few known models like the electroweak standard model and QED, and the limit of application is, for the moment, the 2 to 2 particles reactions involving only external fermions
- AeroCalc is a python package that performs various aeronautical engineering calculations. Currently, it contains the following main modules:
- Antidote is an open source implementation of the IEEE 11073-20601 standard. It also contains the implementation of a D-Bus based 11073 manager service.
- Astro Catalog
- The Astro::Catalog module is an generic, object-oriented astronomical catalogue. It provides access to the online USNO-A2 and Guide Star Catalogues provided by ESO/ST-ECF, and additionally provides read/write access to ARK CLUSTER format files.
- Astroconst makes header files in C, Fortran, Perl, IDL, Java, and GNUplot defining many astrophysical constants useful for scientific programming. A single modifiable data file automatically generates these header files, so you can add new constants to the data file and generate new header files in all appropriate languages without fiddling with each header file individually.
- Astronomical Papers Library
- A C library containing theories of motion of solar system objects that have been published in various astronomical journals such as Astronomy & Astrophysics, the Astronomical Journal, and Astronimcal Papers prepared for the use of the American Ephemeris. Currently this includes such theories as Newcomb's "Tables of the Sun" and all the planets as well as the theory known as "The Improved Lunar Ephemeris".
- 'Asymptote' is a script-based vector graphics language for technical drawing, inspired by MetaPost but with an improved C++-like syntax. It provides for figures the same high-quality level of typesetting that LaTeX does for scientific text. It is a programming language, not just a graphics program, so it can use the best features of both scripts and GUIs. High-level graphics commands are implemented in the language itself, so they can be tailored to specific applications. Labels and equations are typeset with LaTeX for high-quality PostScript output.
- 'atlc' (Arbitrary Transmission Line Calculator) is a computer aided design (CAD) package for designing and analysing electrical transmission lines and directional couplers of totally arbitrary cross section, with an arbitrary number of different dielectrics. The analysis programs in 'atlc' lets users find the electrical properties of a transmission line or coupler whose physical dimensions are known. The design programs lets users physically realise a transmission line or coupler with certain given electrical properties. The package supports multiple CPUs, as some parts are CPU intensive. It is most likely to be useful to radio amateurs.
- Avaneya: Viking Lander Remastered DVD
- Whether you are a fan of science fiction, a space–science enthusiast, hobbyist, photographer, gamer or a patron of grass–roots libre arts and technology, you are sure to find the first successful images from the surface of Mars highly captivating. These mind blowing images were taken by NASA's Viking landers during the highly ambitious, billion–dollar mission first launched in 1975. However, many images were nearly lost to history due to magnetic tape deterioration and archaic proprietary technology.
With NASA's blessing, our team developed the technology to recover many of these images. This research tool was part of the design phase of our parent project, Avaneya — our upcoming libre cerebral science fiction game for the GNU operating system set on Mars, described in the words of Richard Stallman as an exciting, pioneering project.
Originally an internal research tool, overwhelming public interest compelled us to release the technology on this DVD for all. Now everyone can relive the original breathtaking experience that captured the world's attention and marked the first successful moment in history that humanity saw Mars — not as a distant, impersonal, celestial body, beheld through a telescope for centuries, but as a tangible and alien world well within its reach.
