This program is for easy, fast and intuitive visualization and analysis of nuclear spectroscopic data. The program's functionality can be extended with plugins.

Femke (Finite Element Method Kernel Engine) provides a basic set of tools for solving finite element method systems for windows (x86/x64). Femke can be compiled as static library, dynamic library and as managed wrapper library. This project depends heavily on (not included): - OpenCASCADE (2D/3D modelling) - NetGen (2D/3D meshing) - NgSolve (assembling of system marices) - GetFEM++ (assembling of system marices) - OpenBLAS (Optimized Linear Algebra Routines) - SparseSuite (Solving sparse matrices) - MuParser (Expression interpreter)

This project is to implement a kind of educational program which will demonstrate FFT algorithm and help students better understand Fourier transformation.

FGH is program that solves vibrational Schroedinger equation using the Fourier grid hamiltonian method. The program requires potential energy surface and G-matrix defined at the uniform grid of points.

The project's repository has moved to github. Please use the repository at https://github.com/Niels-Bohr-Institute-XNS-StructBiophys/fit2dcorr for the new updated versions. The old version is kept at sourceforge. Keywords: fit2d SAXS azimuthal averaging batch processing absolute units (exposure time, transmission, sample thickness) error bars C++ Unix OpenMP

Fitta is a program for making and plotting statistical fits, simple and weighted fit, high quality plots thanks to the matplotlib library

An interactive tool to study Fourier Series and related physics phenomenons, using open source/free sorftware.

This compact function parser module written in Fortran95 is intended for applications where a set of Fortran-style mathematical expressions is specified at runtime and is then evaluated for a large number of variable values.

free2bind a suite of general purpose bioinformatics tools for computing the minimum free energy (the most stable) binding between two separate RNA molecules.

fropho calculates phonon properties in crystal, which is based on Parlinski-Li-Kawazoe method. Information of forces acting on atoms when an atom is displaced is required as input information. fropho is going to be replaced by phonopy.sourceforge.net.

We've moved to https://github.com/tjod/gMol/wiki gMol is an interactive visualization system used to display and manipulate 3-dimensional models of scientific data, such as molecular structures and surfaces. It contains both OpenGL and web browser widgets that enable flexible user interfaces.

C implementation of the Transfer Matrix Method (TMM) in Acoustics running under Linux and Windows. It features various models for the prediction of sound absorption of acoustical porous materials and aims for capabilities similar to commercial products.

This C++/STL library provides you with the basic genetic algorithms needed for engineering design, such as simple GA and variable population.

Plot package for GALPROP https://sourceforge.net/projects/galprop Plots models and data for cosmic-ray spectra, secondary/primary ratios, gamma rays, synchrotron. Includes gamma-ray source population synthesis and corresponding plots. For gamma rays, convolves models with the Fermi-LAT response. This release is to assess interest. It requires many input data files (not included) which will be made available as required. With the data provided cosmic-ray spectra and ratios and source population synthesis will work. Uses CERN root package. See README for details. Plots produced with GALPLOT can be seen in http://arxiv.org/abs/1101.1381 http://adsabs.harvard.edu/abs/2011A%26A...534A..54S http://adsabs.harvard.edu/abs/2011ApJ...739...29B and http://arxiv.org/abs/1309.2947, published version: http://mnras.oxfordjournals.org/content/early/2013/10/03/mnras.stt1718.abstract . Uses the cosmic-ray database https://sourceforge.net/projects/cosmicraydataba

Genvlin is an easy to use graphical dataplotting environment. It also provides direct access to the data via scripting and a console. You can easily import, export, change, plot, ... all the data.

Package for processing Fluorescence Lifetime Imaging Microscopy (FLIM) Data

This library is a Fortran 95 gnuplot interface for some Unix like OS'es. This provides some routines that enables direct access of a child gnuplot session from a Fortran 95 program. You will need a copy of fortranposix to make this work.

gorbital is a atomic orbital viewer written using gtkmm (gtk--). gorbital displays a 3d interactive view of a electron orbitals. It is meant to be an open source viewer much like Orbital Viewer by David Manthey (http://www.orbitals.com/orb/).

MPI/C++ code to generate initial conditions for cosmological simulations using multiscale gaussian random fields, based on Edmund Bertschinger's GRAFIC-2 package. Provides a replacement for both grafic1 and grafic2.

User friendly interface for calculating electronic properties in graphene-like ribbons. The programs uses the tight binding approximation and mean field Hubbard model to predict electronic properties of graphene-like nanoribbons. See Discussion to ask questions or details Update: New versions of this program will be known as quantum-honeycomp

Grin is a set of tools for solving 2D elliptic equations using boundary elements (Green's functions)

Cosmic-ray hadronic interaction matrices for gamma-ray and other secondaries for an interstellar medium target are available as described in Huang et al. Astroparticle Physics, 27, 429 (2007). These require significant effort in practice to compute emissivities for given input spectra. To supplement these matrices I provide here a C++ class which reads the matrices, interpolates on user-defined particle and gamma-ray energy grids, and computes the gamma-ray emissivity either differential or in user-defined bands. A sample user program is provided which can be edited to provide the required functionality. See also http://sourceforge.net/projects/galprop, which includes more models.

haggies is an optimizing code generator. It can read in expressions in common notation and generate output for many programming languages including C/C++, Java, Fortran, Python and many others.
