GATE is a software package dedicated to numerical simulations in medical imaging and radiotherapy. It supports simulations of Emission Tomography (Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography (SPECT)), Computed Tomography (CT), and Radiotherapy experiments. It makes it easy to use existing Monte Carlo simulation packages according to the requirements of a simulation. It allows accurate description of time-dependent phenomena such as source or detector movement and source decay kinetics. It includes well-validated physics models, geometry modeling tools accommodating complex scanner geometries, models for detector electronic response, and efficient visualization utilities. Modelling of CT scans and calculation of dose can also be performed.
The GCC UPC toolset provides a compilation and execution environment for programs written in the UPC (Unified Parallel C) language. The GCC UPC compiler extends the capabilities of the GNU GCC compiler. The GCC UPC compiler is implemented as a C Language dialect translator, in a fashion similar to the implementation of the GNU Objective C compiler.
GCfilms is an application that can be used to manage a movie collection. Users can enter all the movies they own along with associated informations such as location, category, and rating, and later search for movies using filtering criteria. A plugin system allows information such as running time, actors, and directors to be from Internet sites. Collections can be exported to HTML, XML, SQL, and CSV or imported from Ant Movie Catalog and DVD Profiler.
GCompris is an educational software suite with numerous activities for children aged 2 to 10. Some of the activities are game-orientated, but nonetheless still educational. These include computer discovery (keyboard, mouse, different mouse gestures), algebra (table memory, enumeration, double entry table, mirror image), science (the canal lock, the water cycle, the submarine, electric simulation), geography (place the country on the map), games (chess, memory, connect 4, oware, sudoku), reading practice, and others (learn to tell time, puzzles of famous paintings, vector drawing, cartoon making, etc.). It currently offers in excess of 100 activities, and more are being developed.
GConnect allows organizations of all sizes to integrate their local identity stores with Google Apps to provide single sign on to users and perform on-demand provisioning. GConnect supports authentication and attribute resolution against all LDAP servers and supports advanced integration with Active Directory to provide users with seamless navigation from the corporate environment to Google Apps without having to manually re-enter credentials. Integration to existing authentication mechanisms provided by Web portals or other SSO systems is also possible.
GCstar is an application that can be used to manage collections of different types. Users can enter all the items they own, along with associated information and later perform searches using filtering criteria. A plugin system allows some information to be downloaded automatically from Internet sites. Collections can be exported to many formats, including HTML, XML, CSV, or Tellico file format, or imported from Ant Movie Catalog or Tellico, among others. It currently manages collections of movies, video games, books, music, numismatic, wines, board games, and lets users define their own types of collections.
The Geospatial Data Abstraction Library (GDAL) is a unifying C/C++ API for accessing raster geospatial data, and currently includes formats like GeoTIFF, Erdas Imagine, Arc/Info Binary, CEOS, DTED, GXF, and SDTS. It is intended to provide efficient access, suitable for use in viewer applications, and also attempts to preserve coordinate systems and metadata. Python, C, and C++ interfaces are available.
GEDXchange is a collection of genealogy tools to work with GEDCOM 5.5 and GSF 2.0 files. These tools allow you to create and edit GEDCOM 5.5 Genealogical data files, create Web pages from GEDCOM 5.5 files, export data to GEDML, view contents of genealogical data in various ways, convert GSF 2.0 data format to GEDCOM 5.5, and validate GEDCOM 5.5 files.
