OpenCards is flashcard learning software. The basic idea of OpenCards is to use PowerPoint presentations (*.ppt) as flashcard sets. Slide titles are considered questions and the slide contents their answers. Based on state-of-the-art memorization and scheduling algorithms, OpenCards will help you learn any set of flashcards.
Electronic Engineering Tool is a Web-based tool that includes an electronic formula calculator and converter functions. It very useful when working with electronics, both for engineers and amateurs. For example, it includes converters for dBm-to-Watt and Fahrenheit-to-Celsius, and it can calculate Ohm's law, filters, thermal resistant C/W, SWR, coil inductance, capacitor capacity, and more.
Seismic Toolkit is a tool for processing and displaying seismic signal data in a graphical interface. It reads seismic signals in SAC format, and provides a variety of signal processing, such as filtering, spectral analysis, polarisation analysis, time-frequency representation, Hilbert transform, and singular value decomposition. Some utilities are included for useful seismological applications, like computation of Seismic Moment Mo, Mantle magnitude Mm and Moment magnitude Mw, MTPA spectral analysis, plotting focal mechanisms, computation (and plotting) of instrumental response from poles and zeros, and some usefull GMT (Generic Mapping Tool) scripts for plotting signals, responses, and time-frequency in Postscript files for high quality prints.
FreeSMS (Free Student Management System) is a Web application for managing an educational facility. It manages teachers and students and provides marketing, registration, course management, attendance, and a student evaluation system, and manages courses within a class environment. Profile-based management is supported for administrators, teachers, and students. Teachers and students can be registered online. Students are allowed to manage their own class enrolment and submit course evaluations, and teachers can manage student attendance. The differential factor and elegance of this project lie in the OOP standard and a modular structure. The code is clean and very extendable.
Emilda is an Integrated Library System that features an OPAC, circulation and administration functions, Z39.50 capabilities, and 100% MARC compatibility. MARC compatibility is achieved using the Zebra server from Indexdata in conjunction with MySQL. Emilda is mainly written in PHP, but Perl scripts exist for MARC manipulation and shell interaction.
FísicaLab is an educational application to solve physics problems. The problems are set up by adding elements from the palette to a chalkboard and entering the data for each element. The elements are objects such as blocks, pulleys, motors, and forces. It can use the SI and English unit systems, scientific notation, and many conversion factors. The types of problems that can be solved are kinematics of particles (including circular motion), static analysis of particles and rigid bodies in 2D, dynamic analysis of particles in 2D (excluding the dynamics of circular motion), heat, calorimetry, ideal gas, and expansion. The static and dynamic problems are entered by constructing the free body diagrams of the objects.
granule is a multi-platform (Linux, Windows, NetBSD, Nokia770 Internet Tablet, OpenEmbedded GPE PDAs) flashcards program that implements Leitner space repetition methodology for expanding your vocabulary. It features both short-term and long-term memory training capabilities to improve memory retention.
