SIMPLE_1 (SIMulation Program for Logistics Engin'g) is a discrete/continuous network-oriented simulation language with general-purpose programming language features. The Linux version of this software includes a project management system to automate integration of user-developed C/C++ code into SIMPLE_1 network models. A user's C/C++ code is interfaced with the SIMPLE_1 modeling language through information embedded in comments in the user's header file(s). SIMPLE_1 produces executable files with the help of the C++ compiler.

Haxial Calculator is a high precision mathematical assistant that evaluates normal (infix) expressions to practically any accuracy. Results can be viewed in normal, fraction, or scientific forms, and it allows you to work in any radix. Worksheets enable you to solve larger problems in a more suitable environment, as well as allowing you to save your work. It also incorporates unit and radix conversion utilities and complete support for variables. Haxial Calculator employs a user interface that allows you to freely type expressions with the keyboard instead of mimicking the button presses of a hand-held calculator.

CCruncher is a project for the simulation of large portfolios of SME loans where the unique risk is the default risk. The method used to determine the distribution of losses in the portfolio is the Monte Carlo algorithm, because it allows you to consider multiple variables, such as the date and amount of each payment. The obligors' default times are simulated using a copula with given survival rates and correlations.

The MATNEM Toolbox is a set of MATLAB objects and classes which provides an interface to the Numerical Econometrics Library, a library of econometric routines written in the C language. The aim of the project is to provide an easy, quick, and object-oriented interface for applied econometric analysis. The NEM library also ensures a good level of performance. Among other features, the MATNEM toolbox contains time series data objects, ultra high-frequency data management algorithms, nonlinear estimation routines (ARMA, multiplicative error models (GARCH, ACD)), and frequentist model averaging algorithms (linear regression model, multiplicative error models (GARCH, ACD)).

AutoAbacus is a powerful equation solving library that finds solutions to equation sets. Equations are passed to AutoAbacus as text, and the program attempts to find a solution that satisfies all constraints. The equations can be linear or polynomial, and can include arbitrary functions. By profiling the types of equations in the system and their dependencies on each other, AutoAbacus uses appropriate solution methods to solve individual subsets of equations. Applications range from use in a business rules engine to solving engineering equation systems.

Trad4 is a fully concurrent, thread safe, graph based programming language that scales linearly on multiple cores. It is initially intended for deployment in the financial industry to model real-time risk. Trad4 is proposed as an alternative to the Von Neumann model of computer architecture. It is a new way of arranging programs in memory and a new style of flow-of-control.
