Open Source Java Computer Aided Instruction (CAI) Software

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).

TreeForm Syntax tree drawing software is a Linguistic Syntax/Semantics tree drawing editor. Designed for graphical n-ary tree drawing. Mac users can install the software through the new package, but must give authority through "System Preferences" > "Security & Privacy". Windows and Linux users can run the software through the JAR file directly. All users must have Java 8 or higher installed. https://java.com/en/download/

Software designed for remediation of dyscalculia (or mathematical learning disabilities) in children aged 4-8 and for teaching number sense in kindergarten children. For more information, visit the unicog lab website using the link below. NOTE: To use The Number Race, you may need to download TWO files, the main program (above), AND a language pack. To get to the language packs, click on "Files" on the menu bar above, and select version and the appropriate language. If you are lucky there might be an installer + language pack available as one download. Check "Files" -> version -> Language

Jalmus is a free, open source music education software helping the musicians, especially pianists, to improve their sight-reading. You can train to read music with both exercises on notes or rhythms.

Java provides the concurrent library that simplifies concurrent programming, but this is hard to learn and visualize. This project is a series of animations each illustrating the coding and usage of a component in the java concurrent library.

JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.

JSmol is the extension of the Java-based molecular visualization applet Jmol (jmol.sourceforge.net) as an HTML5 JavaScript-only web app. It can be used in conjunction with the Java applet to provide an alternative to Java when the platform does not support that (iPhone/iPad) or does not support applets (Android). Used in conjunction with the Jmol JavaScript Object (http://wiki.jmol.org/index.php/Jmol_Javascript_Object), JSmol seamlessly offers alternatives to Java on these non-Applet platforms. JSmol can read all the files that Jmol reads. You can do all the scripting that Jmol does. You can create all the buttons and links and such that you are used to creating for Jmol. All of the rendering capability of the Jmol applet is there. JSmol has both a console and a popup menu. JSmol is integrated fully with JSME and JSpecView. A "lite" version of JSmol provides minimal functionality (balls and sticks only) for extremely small-bandwith apps. Released 1/12/2013

An important tool for Algorithm Visualization (AV) developers is a repository of good examples of existing AVs, including source code. The goal of this site is to build a collection of AV implementations from a variety of developers in the AV community.

VeNCrypt adds TLS/X509 encryption and authentication to VNC. It is heavily based on the RealVNC Free Edition, thus being a single fork away from the original creators of VNC, and is fully compliant with the RFB protocol.

PhysMo is a tool for frame-by-frame video analysis of motion. PhysMo can be calibrated to real-world distances, and exports object "X-Y displacement (m) against time (s)" data to Microsoft Excel. This enables calculation of velocity and acceleration
