Dancing Networks attempts to create self-drawing diagrams by applying the laws of motion as we know them today. The process of the diagrams drawing themselves looks like a network that starts its dance in chaos but gravitates toward harmony and order.
Computation and Visualization environment
DataMelt (or "DMelt") is an environment for numeric computation, data analysis, computational statistics, and data visualization. This Java multiplatform program is integrated with a number of scripting languages: Jython (Python), Groovy, JRuby, BeanShell. DMelt can be used to plot functions and data in 2D and 3D, perform statistical tests, data mining, numeric computations, function minimization, linear algebra, solving systems of linear and differential equations. Linear, non-linear and symbolic regression are also available. Neural networks and various data-manipulation methods are integrated using powerful Java API. Elements of symbolic computations using Octave/Matlab scripting are supported.

The Delta code is an nonlinear aeroelastic solver written in fortran 90. At the moment only vortex lattice aerodynamics is available but the hope is for a higher fidelity aerodynamic model to be developed for use in the current code. Linux and Unix.
Peak and global efficiency of radiation source-detector equipment
This software uses Geant4 simulation toolkit for computing detector efficiency (detector response or calibration factor) in terms of peak efficiency and global (gross) efficiency. It is designed mainly for gamma detectors (NaI or HpGe) but can be extended for beta or any other radiation type. Radiation source can be frontal beam, point source, Sarpagan baker (cylinder) and Marinelli baker. Due to the nature of Monte Carlo simulation technique, all geometries involved must be well known for accurate results! Can be used along with RadiationHelper (Beta_Gamma_MC module with Geant4 checkbox selected) but make sure that inside RadiationHelper folder there is MonteCarloPath.txt file (if does not exist, manually create it) having the first line pointing to the path of detector.exe folder (e.g. D:\\DetectorCalibration\\Build) and, if on Linux, next lines pointing to the Geant4 data. RadiationHelper is found here: https://sourceforge.net/projects/radiationhelper/ Source code included

<Temporarily Unavailable Online> This project is aiming at completing a library of open codes (mainly based on MATLAB at present) to deal with Dipoles-Cavity Interaction problems. Common methods, including Green's function method and Master Equation method et al, will be applied to the coding. Samples of calculations and standard comparison with publications using the library will be given for demonstration of the usage. Interface to some commonly used software, such as Lumerical FDTD Solutions, will also be developed in the project. This project is titled under nanophotonics, quantum optics, nano-optics, computational physics and physics.
Plugin orientated Discrete Dipole Approximation (DDA) Solver
Discrete Dipole Approximation Project, is a software package designed to solve the Discrete Dipole Problem by the Discrete Dipole Approximation (DDA) method. This software is desgined to be plugin operated allowing for easy implimincation of new solver methods to improve the efficienty of the code. The plugin support also allow the program to write its output in multiple formats and structures defined by plugins.
Interactive mesh creation tool. Discretizer will create geometry and meshes for three dimensional flow simulations (CFD). Geometry import is not a goal: Discretizer will be furiously fast geometry builder(on many common engineering applications at least)

Patient dose from medical X-ray and other sources
DHPRE software uses Geant4 simulation toolkit for computing organ doses, effective dose and lifetime atributable cancer risk for humans exposed to external radiation field. It is mainly used for patients undergoing X-ray examinations such as radiography, mammography, dental panoramic and CT but can be used for any kind of radiations. INTERFACE is a small program to compute the correction to dosimeter reading when used in conditions other than the calibration ones. This package does not contain all data required to run, i.e. does not contain GEANT4 libraries and GEANT4 nuclear data (for saving space). It does contain however the X-Ray spectrum data. Read README.txt me inside Build folder for how to fix it. Source code included.
