ARO helps physically disabled students to create mathematical drawings
ARO has been developed to assist physically disabled or injured students who cannot create mathematical drawings on paper. It is intended to make maths up to Key Stage 4 more accessible. AQA has agreed to its use in a GCSE maths exam. Anyone who can use a computer with a mouse to access the internet should be able to use ARO. The processes required mimic those of on paper drawing as far as possible. Possible applications include: Graphs of straight lines and smooth curves Compass and ruler constructions Scatter graphs Stem and leaf displays Box plots Histograms Pie charts Simple diagrams. The structure of each drawing is built from individual components which can be placed on the drawing grid without great accuracy. Each can then be positioned exactly using onscreen buttons. The ruler and the protractor can be aligned with any straight line. Drawings can be created on imported background bitmaps. The author was a mathematics lecturer at Plymouth University.

Pick 4 Lottery Software Program
This is a hobby project to create and continually improve different ways to arrive at the smallest amount of pick 4 lottery combinations. The software will feature a built in algorithm as well as user input algorithms that allow calculation for upcoming pick 4 lottery games.
statistical tests & psuedo- random number generators (RNGs, PRNGs)
Randon number generation & testing. The best suite of statistical tests for fast PRNGs anywhere. Multithreaded for speed, command line tools for automation, no upper limit on data size. Also, a variety of C++ pseudo-random number generators with well designed interfaces aimed at practical uses, not just research.
Provides an API, which enables the Interactive Data Language (IDL) user (and developer) to incorporate Space Weather data and metadata resources from the Space Physics Interactive Data Resource (SPIDR) directly into an IDL application. Examples included.
Provides an API, which enables the Matlab or Octave user (and developer) to incorporate Space Weather data and metadata resources from the Space Physics Interactive Data Resource (SPIDR) directly into an Matlab/Octave application. Examples included.
estimates transition probabilities and their standard deviation
BOOTPM is a MatLab script that estimates transition probabilities and their standard deviations both theoretically and using the bootstrap technique. It creates N samples sampling -with replacement- M observations and then computes the relative N TPM's. Then, it simply computes the standard deviation of each transition probability using the distribution across all the N TPM's. It also compares the boostrapped results to results estimated thoeretically, to detect "strange" results. It allows the user to choose a subsample of the data as well as an alternative specification of the states. Editing the script, the user can activate different sections (to plot or save A and S, to change this function into an interactive script, to test the script, to compute other statistics, to customize it...)
The project liquiditymeter is for measuring liquidity in various financial markets.
Powerful Calculus Environment and Matrices Handling Engine
mathSuite is a very powerful Mathematical Suite which deals principally with complex algebric and geometric operations. It is powered by the fabulous ExprEval C Parser. The main purpose of this project is fast math-oriented algorithm virtualization, with an optimized direct text interface. Also it gives you a very powerful and fast Calculus Environment which let you handle easily interchangeable variable lists, matrices, LOGS and Settings Layouts with optimized Items Lists Managing Engine. You'll also be able to execute your own scriptfiles with a basic math-oriented beta script language. Some feature regarding Matrices and Linear Algebra Operations are LU-Factorization, SVD Decomposition, Rank Calculator, Ill Condition Checking and more... There are also a very powerful Linear System Solver and Basic PRELoaded Functions Integrator Engine.
