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.
UMLet is a lightweight tool for rapidly drawing UML diagrams, with a sound and pop-up-free user interface. UMLet lets you draw diagram sketches quickly, teach UML with a simple user interface, and export diagrams to SVG, JPG, PDF, and LaTeX-friendly EPS. It features a fast, text-based way of editing UML elements.
Foswiki is wiki software, supporting the editing of Web pages in an ordinary Web browser by end users. What makes Foswiki special is that it supports the embedding of active and passive macros that enhance the page content (e.g. with global or dynamic information) and allow end-users to build applications that store and process data in a structured manner.
tinyMAS is a multiagent platform that provides base concepts (such as kernel, message, yellow pages, white pages, and transport service) and extended concepts (such as environment, influence, and perception). It aims to provide an easy-to-understand and and easy-to-use platform dedicated for multiagent engineer/research courses. TinyMAS is no longer under development. A large amount of its source code has been merged into the Janus platform.
Piggydb is a flexible and scalable knowledge building platform that supports a heuristic or bottom-up approach to discover new concepts or ideas based on your input. You can begin with using it as a flexible outliner, diary or notebook, and as your database grows, Piggydb helps you to shape or elaborate your own knowledge. Piggydb is a Web application provided as a self-contained package that contains a Web server and database engine.
JGloss is an application for adding reading and translation annotations to words in a Japanese text document. This can be done automatically and manually. When a text document is first opened, kanji words will be looked up in a dictionary and the first reading and translation (if any) used to annotate the word. The user can then edit the annotations: choose among the readings and translations found in the dictionaries, enter your own readings and translations, remove annotations, and add new annotations. The document can be exported as plain text with annotations, HTML, or LaTeX.
Plone is a content management system that is simple to set up, maintain, and modify. It is designed to be a corporate-ready content management system. It is ideal as an intranet and extranet server, as a document/Web publishing system, and as a groupware tool for collaboration between separately located entities. It aims to be a proper content management and publishing system, sharing the same qualities as Teamsite, Livelink, and Documentum.
The goal of Hilbert II, which is in the tradition of Hilbert's program, is the creation of a system that enables a working mathematician to put theorems and proofs (in the formal language of predicate calculus) into it. These proofs are automatically verified by a proof checker. Because this system is not centrally administered and enables references to any location on the Internet, a world wide mathematical knowledge base could be built. It also contains information in "common mathematical language".
