GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.
A Portable General-Purpose Computer Algebra System
REDUCE is an interactive system for general algebraic computations of interest to mathematicians, scientists and engineers. It can be used interactively for simple calculations but also provides a flexible and expressive user programming language. The development of the REDUCE computer algebra system was started in the 1960s by Anthony C. Hearn. Since then, many scientists from all over the world have contributed to its development. REDUCE has a long and distinguished place in the history of computer algebra systems. Other systems that address some of the same issues but sometimes with rather different emphasis are Axiom, Derive, Macsyma (Maxima), Maple, Mathematica and MuPAD. REDUCE primarily runs on either Portable Standard Lisp (PSL) or Codemist Standard Lisp (CSL), both of which are included in the SourceForge distribution. By modern standards, REDUCE is a surprisingly small and compact application, which runs well on all major operating systems.

This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads). - Template-matching and double-helix recognition algorithm is calibrated via setting an image correlation threshold against single-molecule data. - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions. - The motion/drift of fiduciaries (e.g. fluorescent beads) during an experiment can tracked and removed form SM localization data. - 3D localization data can be exported to .csv format for post-processing and visualization. - Basic 3D scatterplot and 2D z-projection histogram visualizations are included.

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.
