...Other systems that address some of the same issues but sometimes with rather different emphasis are Axiom, Derive, Macsyma (Maxima), Maple, Mathematica and MuPAD. REDUCE primarily runs on either Portable Standard Lisp (PSL) or Codemist Standard Lisp (CSL), both of which are included in the SourceForge distribution. By modern standards, REDUCE is a surprisingly small and compact application, which runs well on all major operating systems.

RANSFOIL is a console program to calculate airflow field around an isolated airfoil in low-speed, subsonic, transonic or supersonic regime by numerically solving the Reynolds averaged Navier-Stokes (RANS) equations using mature computational fluid dynamics (CFD) method. As postprocess results, the aerodynamic parameters of the airfoil, e.g., lift coefficient and drag coefficient, can be integrated from the airflow distribution near wall boundary. In addition, the coupling between airflow and heat transfer and the effect of surface roughness on near wall flow are considered by this program, it can be used for engineering calculation of the friction drag and heat transfer coefficients on airfoil surface. RANSFOIL reads coordinates data from a 1D XYZ file which describes the grid points or control points on airfoil as only input, then outputs grid and solution files in 2D PLOT3D format to record grid coordinates and airflow data and a report file to show aerodynamic parameters.

GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. ...

Users load multiecho MRI data and draw ROIs. AnalyzeNNLS creates a T2 distribution from the averaged decay data. Regional fractions and geometric T2 times can be determined.

E.N.M.L. means Environmental Noise Model Language. The target of the project is the definition of a XML specification model mainly devoted to electronic acoustic data exchange. ENML aims to format ANY kind of noise measurement.

...The calculations of the interference profile are performed taking into account the experimental conditions: excitation light incidence angle, wavelength range, luminescent centers distribution. An excitation field depth distribution map (*.bmp), normally calculated by the IMD software (D.L. Windt) is required for the calculations. The module is presented both as LabVIEW virtual instrument and executable requiring LabVIEW runtime (http://joule.ni.com/nidu/cds/view/p/id/2534/lang/en). It may be useful for physicists and material scientists working on the luminescence of thin films.

...It supports instruments from Agilent, Eco Physics, ICS Electronics, Keithley, Omega, Teledyne and other manufacturers. The script language is XML-based. Syntax highlighting is available. The source code is included in the distribution. Contact the project admin to get SVN access.

PDFgetN is a program to process total scattering data obtained on neutron time-of-flight powder diffractometers and to obtain the atomic pair distribution function (PDF).

Distributions Networks Analyzer (DNA) is a tool for simulating (power flow) and analyzing electrical distribution networks. Users can easily implement and test their own power flow, optimal power flow and control algorithms.
