Guided Logic Exercises is a tool that can be used for simplifying logical expressions. It is a java applet that makes use of underlying packages designed for the applet.

This is a python package that allows one to easily create timelines in object-oriented python which later renders to HTML.

The purpose of this program is to plot the waveforms of the hydrogen wave function. The program has 4 option's. First, plotting the radial function, second, plotting the radial probability, third, 2d wave function,last, 3d wave function.

Happy Penguin is a project to demonstrate and promote the usage and solutions of open source software for family and school-age children with virtual machines.

The virtual lab is a NASA-funded project to provide simulated instrumentation. ITG has developed a Virtual Microscope (Virtual SEM and LM) for viewing high-resolution, multi-dimensional image datasets. More info and data: http://virtual.itg.uiuc.edu

Commodity class to facilitate interaction between MATLAB and Bitplane Imaris via COM or ICE interface.

This program is a graphical visualization of various engineering concepts like - - Antenna Radiation patterns (3D full & sectional views) - Electron Bunching in a 2 cavity Klystron amplifier - many more

iSNS is an interactive neural network simulator written in Java/Java3D. The program is intended to be used in lessons of Neural Networks. The program was developed by students as the software project at Charles University in Prague.

Aim is to extract the information from the cadastral maps which is stored as scanned images. The extracted information is stored using graph representation. Then we convert these infomation in to CityGML format to visualize and communicate.

这是一个用来演示二分查找树的程序。 它会随机生成大量的整数，并且将这些整数插入到一个二分查找树中。最后会按照计数的情况绘制出一幅图片。

JChart2D is a easy to use component for displaying two- dimensional traces in a coordinate system written in Java. It supports real-time (animated) charting, custom trace rendering, Multithreading, viewports, automatic scaling and labels. Former UI controls (right click context menu, file menu) have been ported to the subproject jchart2d-uimenu (https://sourceforge.net/projects/jchart2d-uimenu.jchart2d.p/) for the benefit of having no dependencies to 3rd party libraries.

Plotting of mathematical functions, including math expression evaluation

JFunctionViewer is a simple and fast OpenSource function plotter. Since it is written in Java it is Platform independend and can even be run from inside a Browser.

JOELib/JOELib2 is a cheminformatics library which supports SMARTS substructure search, descriptor calculation, processing/filtering pipes, conversion of file formats, 100% pure Java, and interfaces to external programs (e.g. Ghemical) are available.

JRVFSim (Jarvis) is a simulator of a fluid dynamics phenomenon known as radial viscous fingering. Its main feature consists of taking jordan curves and simulating their evolution subject to various parameters. Includes a partial API for numerical methods

A self-sufficient java framework for numerical solution of ODEs (diff eqs) and visualization. Samples are aeronautics/astronautics/physics/rocketry themed. Focus on clean design, modularity, reusability and documentation. Educational project.

Jpowder, http://www.jpowder.org, is a Java viewer of powder diffraction data, and is a collaborative project between the ISIS Facility of the STFC and the E-Learning and Software Develepment Unit of the Kasem Bundit University.

Open source animation of kmeans clustering in X Window System using the C++ libplotter library. Supports Linux, Mac, and BSD. Includes common initialization methods such as Forgy, Macqueen, random, and angular. Sample videos are available through the Files Tab above. The SVN repo is accessible thorugh the Code Tab above. Requires a C++ compiler, libplot-dev, and libncurses5-dev Mac alternative to libplot-dev: macports plotutils +x11

This is a ActiveX/ATL component that shows molecular structures in 3D. It can read atomistic .pdb and .xyz file formats. This control is made very simple and flexible. It may be useful for chemists or other scientists to put molecular structures in presentations such as power point, with the ability to rotate or zoom using the mouse. It can also be used in developing graphical user interface for molecular calculations, and in any programming IDE that allows insertion of ActiveX controls. The models are rendered using OpenGL, therefore it exploits optimizations provided by the graphics cards. NEW: Render as PNG with transparent background. Added small application that allows user to open molecular file and render it as a PNG file image PNG with transparent background. Can be quite useful in presentations and visual processing.

This project aims at creating a Java application/library that is capable of generating a syntax diagramm of a (programming) language in the SVG graphics format.

L\'application Web de la ligne du temps (timeline) permet à l\'utilisateur de consulter, de créer et de partager des lignes du temps et des scénarios d\'apprentissage, qui sont représentées graphiquement avec une échelle temporelle. Flex 2 et Ruby.

Lindenmayer ist ein Programm zur Visualisierung von L- bzw Lindenmayer-Systemen mittels hübscher Baumgrafiken. Die ausführbaren Dateien und Hinweise zum Quellcode finden Sie auf unserer Homepage unter http://lindenmayer.berlios.de/.

Currently, this project consists of a pure java math expression parser optimized for repeated evaluation. Development of an interactive 3D math visualization application based on this parser is planned for the future.
