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. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.

The repository has been moved to: https://github.com/wojdyr/fityk. Fityk is nonlinear curve-fitting and data analysis software. It is specialized in fitting peaks (bell-shaped functions like Gaussian, Loretzian, Pearson7, Voigt) to experimental data.

FRIDA (flexible rapid interactive data analysis) is a generic program for manipulating, fitting, and plotting x,z,y data. It is primarily aimed at spectral analysis, especially in neutron scattering. Note: project has moved away from sf.net.

NSB entropy and mutual information estimator; applications to the analysis of neural code.

Continuous wavelet transform library

This program is useful for visualizing bifurcations of chaotic systems. In other words, it plots the data and provides useful tools for analyzing and manipulating the data generated by chaotic systems.

ConcordeDSP -- A user friendly, Open Source, GUI-based DSP filter design and waveform analysis environment

This project concerns the design and implementation of an open-source flocking boids simulator, designed as a tool to analyze and characterize flock-like collective emerging behaviors. Each boid is conceived as an active agent and modelled by a point-mass approximation. Boid movements in a 3D space are guided by a set of elementary steering behaviors, each implemented as a force acting on the boid's point mass. Each boid is affected by interactions with both the environment and other boids. The set of considered behaviors are inspired by the well-known approach introduced in 1987 by C. W. Reynolds. The simulator delivers a 3D visual interface and provides as an output file all the instantaneous microscopic information related to each boid (positions and velocities over time), allowing in this way subsequent analysis, such as searching for synthetic and higher-level descriptions of collective behaviors, relying for instance on global network and meta-structural properties.

Madeline is an open-source clone of Mathematica. It hopes to provide the same efficiency and robustness that are needed for high-end mathematics.

MathROOT is a tool for high-energy physicists to access the ROOT data analysis framework from within Mathematica

SpecTcl is a Tcl/Tk based histogrammer suitable for analysis of nuclear physics data. SpecTcl is relatively easy to learn, and is based on top of a very open C++ histogramming class framework. SpecTcl has been developed under NSF grant PHY-9528844 and DOE grant DE-SC0000661 Note that as of July 2023, all future development and release packages will be occur at https://github.com/FRIBDAQ/SpecTcl

NTuple is a Python module used by high-energy physicists and astrophysicists to easily and efficiently access ntuple data stored in large ROOT data stores. Specifically, NTuple provides a friendly Pythonic interface to TNtuples and TTrees stored in TFiles

A tool for visualisation and analysis of STM and STS results. Currently supports RHK, WinSPM, Nanonis and Createc file formats. Other formats can be added. Tools are made available by plugins and are currently focused on spectroscopy manipulation.

SPIW is a MATLAB toolbox, for automated processing of scanning probe microscope images. Tools are applicable to all SPM images, but the main focus is on images with atomic or molecular resolution. SPIW is primarily a MATLAB toolbox with functions designed to be called in a user's own script. SPIW also has a very basic GUI for browsing and exporting images. For information on SPIW's performance see our publication ( http://dx.doi.org/10.1063/1.4827076 ) in the Review of Scientific Instruments. A related open-source project SPIEPy (https://pypi.python.org/pypi/SPIEPy/) is developing a python library to for automated SPM imaged enhancement. SPIEPy brings many SPIW algorithms to the Python user.

Very small but powerful object oriented library.

SonicData is a data collection and analysis program used in connection with a sound card voltage-to-frequency interface. Its intended use is for laboratory instrumentation.

TMVA is a ROOT-integrated toolkit for multivariate classification and regression analysis. TMVA performs the training, testing and performance evaluation of a large variety of multivariate methods. Since 2013, TMVA has been fully integrated with ROOT and is distributed as part of it. The new homepage of TMVA is https://root.cern

Al2 is a language, close to C++ and Java, designed for use in mathematics and science, but is procedural unlike Mathematica and Maple. Like C++, class operators can be defined. Like Java, there is no need for header files. Aled is an interface to AL2.

For a given signal, pstool calculates a one-sided power spectrum, i.e. the portion of a signal's power falling within given frequency bins. This is done by employing a one-dimensional real-to-complex FFT routine on an MPI cluster.
