AeroCalc AeroCalc is a python package that performs various aeronautical engineering calculations. Currently, it contains the following main modules:

• airspeed
• default_units
• ssec
• std_atm
• unit_conversion

GDC GDC is a utility to calculate compressible flow (Gas Dynamics Calculator). It provides calculations for isentropic nozzle, isothermal nozzle, isothermal, Fanno, Rayleigh flow, etc. It also provide calculations for shock and oblique shock by direct calculations (no iteration, probably the only one that can do it). The result are in plain text, LaTeX, or a range of values.

Icarus Verilog Icarus Verilog is a Verilog simulation and synthesis tool. It operates as a compiler, compiling source code writen in Verilog (IEEE-1364) into some target format. For batch simulation, the compiler can generate an intermediate form called vvp assembly. This intermediate form is executed by the ``vvp command. For synthesis, the compiler generates netlists in the desired format. The compiler proper is intended to parse and elaborate design descriptions written to the IEEE standard IEEE Std 1364-2001. The standard proper was released towards the middle of the year 2001, though in a rather pricey electronic form. This is a fairly large and complex standard, so it will take some time for it to get there, but that's the goal. NOTE: Under the Version information please browse the Installation link to find the proper download link.

IntelHEX The Intel HEX file format widely used in microprocessors and microcontrollers area as the de-facto standard for representation of code for programming microelectronic devices. This library provides support for reading, modifying, writing Intel HEX files. You also can create new files from the scratch, convert from and/or to binary form, print human-readable dump of data, merge 2 or more files into one, etc. There are several helper scripts: hex2bin, bin2hex, hex2dump and hexmerge.

Mastrave Mastrave is a free software library written to perform vectorized scientific computing and to be as compatible as possible with both GNU Octave and Matlab computing frameworks, offering general purpose, portable and freely available features for the scientific community. Mastrave is mostly oriented to ease complex modeling tasks such as those typically needed within environmental models, even when involving irregular and heterogeneous data series.

Semantic array programming

The Mastrave project attempts to allow a more effective, quick interoperability between GNU Octave and Matlab users by using a reasonably well documented wrap around the main incompatibilities between those computing environments and by promoting a reasonably general idiom based on their common, stable syntagms. It also promotes the systematic adoption of data-transformation abstractions and lightweight semantic constraints to enable concise and reliable implementations of models following the paradigm of semantic array programming.

There are a couple of underlying ideas: library design is language design and vice versa (Bell labs); language notation is definitely a "tool of thought" (Iverson), in the sense that there is a feedback between programming/mathematical notation and the ability to think new scientific insights. And perhaps ethic ones.

Science and society

Mastrave is free software, which is software respecting your freedom. As many other free scientific software packages, it is offered to the scientific community to also promote the development of a free society more concerned about cooperation rather than competitiveness, heading toward knowledge and culture freedom.

Such a vision implies the possibility for motivated individuals to freely access, review and contribute even to the cutting-edge academic culture. This possibility relies on the development of tools and methodologies helping to overcome economic, organizational and institutional barriers (i.e. knowledge oligopolies) while systematically promoting reproducible research. This is a long-term goal to which the free software paradigm can and has been able to actively cooperate.

NumPy The fundamental package needed for scientific computing with Python is called NumPy. This package contains:

• a powerful N-dimensional array object
• sophisticated (broadcasting) functions
• basic linear algebra functions
• basic Fourier transforms
• sophisticated random number capabilities
• tools for integrating Fortran code
• tools for integrating C/C++ code

Besides its obvious scientific uses, NumPy can also be used as an efficient multi-dimensional container of generic data. Arbitrary data-types can be defined. This allows NumPy to seamlessly and speedily integrate with a wide-variety of databases. NumPy derives from the old Numeric code base and can be used as a replacement for Numeric. It also adds the features introduced by Numarray and can also be used to replace Numarray.

OpenVulture The OpenVulture project is a free and open source software package for controlling autonomous vehicles brought to you by the fantabulous 757 Labs team. The primary purpose of this project is to provide a simple, free and nearly-dependency-free application (Vulture) and library (libvulture) to facilitate the software needs of an autonomous platform. Free, in the former case, refers to both freedom and cost. Such platforms (e.g. UAV, automated R/C car, etc) can be constructed cheaply and employ aspects of the OpenVulture software to act as the "brain" of the platform, steering it to waypoints and directing the platform in following pre-planed patterns/paths.
