AnharmoniCAOS
Cagliari-Orsay model for anharmonic molecular spectra in 2nd order PT

The VPT2-screened PyVCI program package is a general purpose open-source code for simulating accurate molecular spectra, based upon force field expansions of the potential energy surface in normal mode coordinates. It includes harmonic normal coordinate analysis, vibrational perturbation theory and vibrational configuration interaction (VCI) algorithms, with VCI matrix elements chosen iteratively according to VPT2 energy contributions, across a range of significance thresholds. It is implemented primarily in Python for accessibility but with time-consuming routines written in C (produced using Cython). ...

PyVCI
Vibrational configuration interaction code for simulating IR spectra
The PyVCI program package is a general purpose open-source code for simulating accurate molecular spectra, based upon force field expansions of the potential energy surface in normal mode coordinates. It includes harmonic normal coordinate analysis and vibrational configuration interaction (VCI) algorithms, implemented primarily in Python for accessibility but with time-consuming routines written in C. Coriolis coupling terms may be optionally included in the vibrational Hamiltonian. Quartic force fields are obtained from the PyPES library of high quality analytical potential energy surfaces (http://sourceforge.net/projects/pypes-lib) or by numerical differentiation of analytic second derivatives generated using the GAMESS quantum chemical program package (http://www.msg.ameslab.gov/gamess/). -

PhaseGo
Automatic calculation and plot of phase diagram
...For the dynamic response properties of materials, Phasego can automatically find the Hugoniot pressure-volume and pressure-temperature relations according to the Rankine-Hugoniot conditions. All these qualities can be obtained based on the quasi-harmonic approximation (QHA) and/or full anharmonic free energy corrections (AFEC) from the high-temperature phonon density of states (DOS). More interestingly, with full anharmonic effects the possible phase boundaries of all the structures provided are analyzed and plotted automatically. So the high pressure and temperature phase diagram can be constructed and plotted easily by Phasego. -

libsharp
Library for spherical harmonic transforms (SHT)
NOTE: as of April 24, 2015, libsharp development has moved to Github (https://github.com/dagss/libsharp). Libsharp is a collection of algorithms for efficient conversion between maps on the sphere and their spherical harmonic coefficients. It supports a wide range of pixelisations (including HEALPix, GLESP, and ECP). This library is a successor of libpsht (http://sourceforge.net/projects/libpsht). A scientific overview over the functionality is given in the paper available at http://arxiv.org/abs/1303.4945. -

Mass-Spring System Simulation
The program simulates simple harmonic motion using a spring and block.
The program simulates simple harmonic motion using a spring-mass system. The mass of the block, the spring constant, and the position to which the spring is stretched can all be adjusted (decimal values can be used). When the simulation begins the block oscillates in accordance with these given values and with the given scale. The scale can be adjusted. NOTE: For Windows 8 users, Windows SmartScreen may stop you from opening this program but I promise this is not a malicious file. ... -

galprop_skymap_convert
Convert galprop skymaps to standard healpix
...This program performs this conversion, outputs both the original energy bins and energy-integrated spectra, and in addition convolves with a user-defined Gaussian both in energy bins and energy-integrated. Also outputs the spherical harmonic decomposition as HealPix, per energy bin. There is also an option to divide by a second HealPix file, for example to give intensity if file 1 is counts and file 2 is exposure, to give intensity. Now also converts back. -

Arpeggio
Harmonic analysis of ChIP-seq experiments
...Importantly, these interaction patterns broadly reflect the biological properties of the binding events. To generate these profiles, termed Arpeggio profiles, we applied harmonic deconvolution techniques to the autocorrelation profiles of the ChIP-seq signals. A detailed tutorial is available in the Wiki page (http://sourceforge.net/p/arpeggio/wiki/Home/) -

TPFA-the answer book
Solutions of problems in functional analysis
The goal of the 5 Volumes of Theorems and Problems in Functional Analysis - The Answer Book is to provide the complete solutions for the exercises compiled in the ”core book” by A.A Kirillov and A.Gvichiani, ”Theorems and Problems in Functional Analysis, MIR editions, 1979” (TPFA). The problems cover most of the concepts of classical Functional Analysis: Distributions, Hilbert Spaces, Harmonic Analysis, Spectral Theory... The 828 exercises provided in TPFA represent an incredibly rich source of problems in order to train oneself in these fields. These exercises also bring numerous original entry points for various subjects outside the field of the theory developed in the core book. Finally, it is important to note that while the volumes are obviously naturally bundled with the core book, they have been written completely independently of it... -

The Harmony of the World
A fair attempt at the Keplerian tradition to explore the solar system
Nowadays the idea of a music of the spheres, or a cosmic music that descends from the planets seems more like poetic philosophy than anything scientific. However, when the scientist Kepler discovered special principles about planetary motion, he also reconsidered the music. Apparently his observance of a harmonic law of planetary motion was reason for him to propose a computable system of pitch and harmony deriving from angular velocity. The purpose of the programming project is as a tool to examine his system. With Java 2, it provides an open-source solution for listening to harmonies so generated by planetary motion. This program can run on any computer provided with a Java Virtual Machine (Rev 1.5 or greater). ... -
