Open Source Physics Software - Page 55

This software is written in Fortran 90 and is related to forward and inverse problems for the Helmholtz equation in 2-D.

sheep is an open source rigid body dynamics engine written in modern, strictly portable C++. It features collisions between hierarchies of convex polyhedra (using the SWIFT library), resting contacts handling and an extensible set of joints.

sidmon is a python program for receiving and recording submarine-transmitter signal intensities and directions in the VLF frequency range using a computer sound card. The intensities of these signals reflect the ability of radio waves at those wavelengths to propagate in what is essentially a waveguide formed by the earth and the ionosphere above it. Fluctuations in those signal intensities and directions often reflect daytime perturbations of the ionosphere by solar processes, such as solar flares and coronal mass ejections, making VLF receivers useful tools for probing the sun and the earth's ionosphere. For additional general information, see the web page at http://solar-center.stanford.edu/SID/.

This package is a VLF receiver for monitoring VLF transmitter signals for evidence of transients indicating ionospheric disturbances, usually caused by x-ray bursts from the sun. It takes sample pairs from dual-channel sound cards and spectrally processes them to Stokes parameters. Data are plotted as time series and in scatter plots.

Slabs is a software for analysing the optical reflectances of multilayer dielectric structures at oblique incidence.

You play a 2d blob that reshapes to grab bend bounce and swing on objects floating in midair (like a platformer game), except acrobaticly your view spins when your blob does. I'm planning a huge multiplayer world, some blobs played by people holding a bendable loop game controller (tape a 1 meter cut of thick extension cord into a loop) in front of webcam and bend it to bend your blob on screen, and other blobs controlled by AI. This is a game for general AI research in a fun way people can do together. The physics and vision algorithm is half working in version 0.3.0. The gameplay is better experienced in 0.2 which is controlled with the mouse so you dont have enough freedom of movement compared to webcam. This small file contains its own source code including occamserver, a tiny general java server I built which I'll adjust to allow http streaming connections to stay open for faster ajax than a new web call each time. The reshaping and bouncing physics is by springs.

spclib provides a free and open library for the manipulation of spectral files in the Grams SPC format

Specfe is a graphical front end program intended to aid the use of the 'spec' data acquisition software. It can display interactive graphs of scanned data and present a user-friendly graphical interface to several of the more common spec commands.

SpecMark (spectral Markov) is a method for calculating the joint probability distribution over species in a regulatory network.

sph2000 is an object-oriented parallel framework for physical particle simulations with the SPH-method (Smoothed Particle Hydrodynamics)

SPINNEY provides an implementation of helicity spinors and related algorithms for the symbolical manipulation program FORM. The description of this package is published in http://arxiv.org/abs/1008.0803 .

N-body program for astrophysical simulations

Cosmic ray electrons scatter on the photon fields around stars, including the sun, to create gamma rays by the inverse Compton effect. This program computes the spectrum and angular distribution of this emission. The software also includes general-purpose routines for inverse Compton scattering on a given electron spectrum, for example for interstellar or astrophysical source modelling. For further information see these publications: http://arxiv.org/abs/astro-ph/0607563, http://arxiv.org/abs/0801.2178, http://arxiv.org/abs/1104.2093, http://adsabs.harvard.edu/abs/2013NuPhS.239..266O and this conference presentation: https://confluence.slac.stanford.edu/download/attachments/130879399/poster_symposium_sun_2012.pdf and the corresponding conference paper http://arxiv.org/abs/1307.6798 2017 June 16: now available from gitlab https://gitlab.mpcdf.mpg.de/aws/stellarics which will be used for future develpments.

This project contains a dependency database for epics-sumo <https://epics-sumo.sourceforge.io> with some common EPICS device supports published by various institutions. You can use this after you installed sumo with 'sumo config new NEWDIRECTORY sumo-free INITIAL'.

A Java toolkit for the creation of physics simulations and 3D visualizations. Developed as part of the Technology Enabled Active Learning (TEAL) initiative at MIT.

Tkaero is a simple compressible aerodynamic calculator developed in Tcl/Tk.

A simple GUI for gnuplot in Tcl/Tk. The main goal of this project is to help novice/lazy users to use datafile oriented operations of 2D plotting. BETA version is available in "Download" section. Feel free to post Bug/Request/Patch in the Tracker. GNUP

trafo is a console-based "E-I" transformer calculator. It allows you to easily calculate all the necessary information to build an "E-I" transformer by only providing a few input parameters. This programs is for all of those who don't want to spend more time calculating transformers manually amd would like some automation.

Computational package to study transition metal atoms in surfaces, focusing on the effects of crystal field, spin orbit coupling and electronic interactions. Inputs are written in an user friendly interface, and creates a pdf and graphics with the results.
