Open Source Computer Aided Instruction (CAI) Software

Qucs is a circuit simulator with graphical user interface. The software aims to support all kinds of circuit simulation types, e.g. DC, AC, S-parameter, Transient, Noise and Harmonic Balance analysis. Pure digital simulations are also supported.

Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

blat(mat) is a Braille to print translator for maths. It takes a Spanish Six-dot Mathematical Braille (not Nemeth Code) text and converts it to an HTML file ready to be translated into XHTML+MathML by ASCIIMathML (javascript).

Software de Mapas de Argumentos con interfaz gráfica diseñado con el objetivo específico (aunque no excluyente) de analizar la estructura argumentativa de demostraciones matemáticas, utilizando el modelo de Toulmin. Además, el contenido de los elementos puede ser tanto texto como imágenes, lo que permite guardar como imagen expresiones matemáticas escritas en LaTeX (utilizando software de apoyo como KLatexFormula). Se puede imprimir el diagrama y exportarlo a formato imagen (varios formatos) o generar un fichero HTML que contenga el diagrama y su contenido. Incorpora la herramienta "Estadísticas" que permite calcular totales, máximo, mínimos y medias de los elementos de varias demostraciones guardadas.

Microchip's PIC simulator. Simulates a circuit with dispositives as a P16F84 microcontroller, LEDs, displays and LCDs. Extensible with plugins.

Jaguar is a GPL tool written in Java (tm), provides an infrastructure of libraries, engines and graphical applications that support most of the models and algorithms reviewed in a regular undergraduate computer theory (automata & formal lang) course.

Pattern recognition software package. It includes several classification and clustering algorithms. It can read data from a set of images, an ASCII file or a JDBC connection. A small TCP data server with its corresponding JDBC driver is included.

Ouroborus is an artificial life framework for mobile agents on a background of cellular automata. It can be used to teach and research topics such as population genetics, ecology and evolution. The demo includes a curses view and live Csound audio.

RunAsApproximator es un programa java multilenguaje que implementa algoritmos numéricos. Los datos de entrada son aquellos requeridos por cada algoritmo y los de salida son resultado final y los datos intermedios necesarios para alcanzar su resolución.

SimAlgPro - it is a tool to simulate the main algorithms for processor planning. to contribute to the learning process. It allows visualize of interactive form the algorithm application and results.

This program converts calculator-style ASCII math notation (the same that ASCIIMathML uses) to Spanish Braille mathematics notation (not Nemeth Code).
