SSF aims at providing an easy to use and efficient framework for physics sim & visuals in small scientific simulations in real-time, as well as games, which are inherently real-time applications.

SmartBoard is the physic2D simulation program. It makes a user can freehand draw an object , and then simulate it, so SmartBoard is able to help a user to understand physic easily. We implement and edit Phys2D library to be physical engine of SmartBoard.

A program to quantify snow cover stratigraphy and its variability

Structures of arrays (SoA) are generally faster than arrays of structures (AoS) while AoS are more handy. This project (SoAx) combines the advantages of both. By means of C++(11) meta-template programming SoAx achieves maximal performance (efficient use of vector units and cache of modern CPUs) while providing a very convenient user interface (including object-oriented element handling) and flexibility. It has been designed to handle list-like sets of particles (similar to struct {int id; double[3] pos; float[3] vel;};) in the context of high-performance numerical simulations. It can be applied to many other problems. Please check the sample file main.cpp to see examples of code that you can write with SoAx.

This is an application that computes the date and time in formats appropriate for astronomers - julian date, sidereal time, modified julian date, truncated julian date. Extremely accurate, includes correction for apparent sidereal time.

Programs to download and work with satellite measurements, calculate solar wind (SW) propagation time and compare data to other satellites. It uses and compares different modern techniques to determine the SW planar structures orientation.

The aim of project is creating program environment for solving some integral equations, arising at solving mathematical problems of the diffraction theory.

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.

SoundBox Studio aims to be a software for helping projecting Sound Boxes.

Now maintained at github.com/spacepy/spacepy Space Science library for Python - contains superposed epoch classes, drift shell tracing, access to magnetic field models, streamline tracing, bootstrap confidence limits, time and coordinate conversions, etc.

Sparkle 2d physics engine is a real time physics simulation library for use primarily in games.

Spasmos is a Python package that allows scientists to simulate the dynamics of highly collisional plasmas using a number of numerical methods.

Spectra processor for 1D, 2D or 3D data sets obtained in x-ray and neutron scattering experiments. Includes an elaborate batch system as well as visualization tools.

SpectraScan loads images from scanned curves and exports the pixel coordinates of the curve in csv format. This program is especially for scans of ESR or other spectra, which are to be converted into a computer readable format.

SpEcon is a unit conversion program which emphasis on energy units commonly used in spectroscopy.

SpectrumGUI can generate filtered spectra for various x-ray tubes and can display attenuation coefficients for various materials. It also computes exposure and beam quality for various tube settings.

Physical simulation of particle movements. The computer program SphereSim simulates and animates the behavior and the movement of particles in a space. By forces (such as gravity in a particular direction and between the particles, repulsion of the particles against each other and from the walls, Lennard-Jones-Potential between particles) different physical effects in particle groups are calculated and shown, such as the Brownian motion. The application uses the programming language C++ and the Qt, OpenGL and OpenMP libraries.

Develop a basic understanding of the behavior of polar spherical coordinates through selected examples. Provide sample files for diverse mathematics engines

Finite Element Physics engine that simulates springs, masses, collision and air resistance, using SI units in order to be to scale with reality.

The fluid simulator consists of a core library and a GUI. The core makes all calculations based on the paper "Stable Fluids" by Jos Stam. It is able to simulate fluid flow in abritrary time steps. Support for boundaries is included.

StochFit utilizes stochastic fitting methods to model specular x-ray reflectivity or neutron reflectivity data. It provides an easy to use graphical user interface for both model dependent and model independent methods.

This code performs the stochastic tourist walk dynamics over a one-dimensional disordered system. The code return the density of distinct visited sites on one trajectory.
