Graph visualization using hyperbolic geometry (hyperbolic trees, but also general graphs). Applications cover web site structures, topic maps, organisational charts and wikis.

SWire is a software interface enabling us to query Stata for the executing of basic operations like reading or writing data. The core of SWire is a Java plugin which functions as a server and it can be queried by using the HTTP protocol. SWire is in essence a wrapper around the Stata-Java API and all the functions relating to this API can, therefore, be externally called by clients. SWire can be interrogated on a local network and it accepts AJAX queries, thus enabling the development of web applications which provide the user with graphical user interfaces. For example, a web application running on a browser can interact with Stata on a local network; this application could be a data entry form or an automatic report. By providing a communication protocol, SWire makes it possible to connect Stata with many other applications for data exchange and basic interaction, thereby extending the capabilities of Stata. SWire requires Stata >=13.

This is a map internet web service based on a huge raster maps or satellite images for tracking and monitoring the mobile objects (cars etc) using GPS.

Algebra Helper shows how signs change when moving a quantity from one side of an equation to the other. Algebra Helper is implemented in JavaScript.

JavaScript crossword puzzle builder with internationalized math capabilities. Generate unlimited layouts of user-supplied words and equations. Use file->print (to file) to save

A distributed effort to calculate pi across many computers, 9 digits at a time with minimal computer knowledge.

Automatically copies files to and from a web server.

This project deals with a new concept of the heterogeneous grid for acceleration of the numerical linear algebra computing. We design this grid with respect to maximal ratio between cost and computational power. It allows a parallelization of scientific codes with minimal programming effort. We also optimize grid concept to be less sensitive to network parameters.

A Java application that controls and simulates the flow of containers at the Rotterdam harbour.

Gamoliyas is an open source John Conway's Game of Life game totally written in DHTML (JavaScript, CSS and HTML). Uses mouse and keyboard. Very configurable. This cross-platform and cross-browser game was tested under BeOS, Linux, *BSD, Windows and other

The General Intensional Programming System (GIPSY) consists in three modular sub-systems: The General Intensional Programming Language Compiler (GIPC) ; the General Eduction Engine (GEE), and the Intensional Run-time Programming Environment (RIPE).

Graidle is a project that is proposed to create a web application to generate graph diagrams. There are several classes specialized in generating histograms(horizontal),line(filled) pie and spider charts.

In the tradition of Hilbert's program we create a formal correct (checkable by a proof verifier) but readable (like an ordinary LaTeX textbook) mathematical knowledge base which is freely accessible within the internet. Logic and set theory started.

Realtime bigdata tool at the bit level based on immutable AVL forest which can be run in memory or, in future versions, as a merkle forest like a blockchain. Main object is a sparse bit string (Bits) that efficiently scales up to 2^63 bits normally compressed as forest has duplicated substrings. Bits objects support reading bit, byte, short, int, or long (Java primitives) at any bit index in 64 bit range. Example: instead of building a class to hold a header and then data, represent all of that as Bits, subranges of them, and ints for sizes of its parts. Expansion ability for other kinds of compression, since Bits is a Java interface. Main functions on bits are substring, concat, number of 0 or 1 bits, and number of bits (size). All those operations can be done millions of times per second regardless of size because the AVL forest reuses existing branches recursively. Theres a scalar (originally for copy/pasting subranges of sounds) and a bit Java package. Sparse n dimensional matrix.

JavaMath is oriented toward integrating existing compute engines, such as Maple, Mathematica or GAP, into Internet accessible mathematical services.

A web-based, automated search engine that responds to user feedback through the use of artificial intelligence.

MNGL (Math, Network and Graphic library) is a library which is composed by a lot of different modules to help programmers to develop their applications and softwares.

Make It True is a web application to practice fundamental algebra procedures used when manipulating equations. The application generates arbitrary equations containing 1-4 variables. It is for the student to provide values for these variables which make the equation true. For example, in the screenshot above the equation is: 18-64-c*d=4. The student must choose values for c and d which result in a true statement. One approach would be to solve for the product "c*d" and then choose 2 numbers whose product satisfies what's needed. Like this: 18-64-c*d=4 18-64-4=c*d c*d=-50 Then the student could pick any two numbers with product of -50, like c=-25 and d=2. Another approach would be to pick any number for c, then express d in terms of that number. For example, if the student arbitrarily chose c=13 then: 18-64-c*d=4 18-64-13*d=4 d=(4-18+64)/(-13)
