- AeroCalc is a python package that performs various aeronautical engineering calculations. Currently, it contains the following main modules:
- BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.
- Beremiz is an integrated development environment for machine automation. It is Free Software, conforming to IEC-61131 among other standards. It relies on open standards to be independent of the targeted device, and let you turn any processor into a PLC. Beremiz includes tools to create HMI, and to connect your PLC programs to existing supervisions, databases, or fieldbuses.
- Life cycle assessment, Monte Carlo uncertainty analysis, visualization of results
- GNU C-Graph is a tool for visualizing the mathematical operation of convolution underlying natural phenomena susceptible to analysis in terms of engineering signals and systems theory. "C-Graph" is an abbreviation for "Convolution Graph". The package is derived from the BSc. Honours dissertation in Electrical Engineering "Interactive Computer Package Demonstrating: Sampling Convolution and the FFT", Adrienne Gaye Thompson, University of Aberdeen (1983). The package computes the linear convolution of two signals in the time domain then compares their circular convolution by demonstrating the convolution theorem. Each signal is modelled by a register of discrete values simulating samples of a signal, and the discrete Fourier transform (DFT) computed by means of the Fast Fourier Transform (FFT). GNU C-Graph is interactive, prompting the user to enter character or numerical values from the keyboard, dispensing with the learning curve for writing code. The software will be useful to students of signals and systems theory. C-Graph is written in contemporary Fortran. You can find pre-GNU development versions at: <http://codeartnow.com/code/download/c-graph-1/c-graph-version-2-preview>. Adrienne Gaye Thompson is the sole author of GNU C-Graph and looks forward to sharing further development with the FLOSS community.
- This software is associated to an hardware part a modular battery charger/discharger. It allow to describe and control any kind of law of charge/discharge. Charge and discharge scenarios are described into a configuration file. During the charge/discharge process battery voltage is continuously monitored and some data are displayed and recorded for further analysis. Chyradeche has been tested on a Raspberry Pi A+ under Raspbian Lite operating system. The Rapsberry Pi needs to be connected to the Chadeche hardware.
- Degate is a tool that aids VLSI- reverse engineering of digital logic in integrated circuits (ICs). Degate helps you to explore layered images from ICs. It matches standard cells on the imagery given by graphical templates and to some degree degate matches vias and wires and assists you in tracing circuit paths and in reconstructing the net list. Degate is not a completely automatic analyzing tool. Degate helps you with some automation in your manual chip reverse engineering process.
- Electric is a CAD program for designing electrical circuits, handling custom IC layout, schematic drawing and hardware description language specifications. Several CAD operations are supported, such as rule checking and simulation. Many different types of designs can be produced and input or output in a wide variety of formats. GNU Electric offers a wide range of synthesis and analysis tools for working on the circuitry, including design rule checking, simulation, routing, layout vs. schematic, logical effort… It also has many importers and exporters for interfacing to other EDA (Electronic Design Automation) systems. It even has a constraint system for managing chip layout.
- Empirical gramians can be computed for linear and nonlinear control systems for purposes of model order reduction, uncertainty quantification or system identification. Model reduction using empirical gramians can be applied to the state space, the parameter space of dynamical systems and control systems. The emgr framework is a compact open source toolbox for (empirical) gramian-based model reduction and compatible with OCTAVE and MATLAB.
- FreeSnell is a program which computes optical properties of multilayer thin-film coatings. Dielectric, metallic, and granular metallic films are supported. The FreeSnell package includes a SCM script (program) "nk" to create, manage, and query a refractive-index spectral database. FreeSnell is an application of the SCM Scheme implementation and the WB B-tree database package.
