Zeobuilder is a user-friendly GUI toolkit for the construction of advanced molecular models. It is extensible via a plugin framework and contains several advanced tools for building, aligning, manipulating, and analyzing molecular structures. It describes a molecular model with a hierarchical data-structure of reference frames. This facilitates operations on models at different levels of detail.
APBS is a software package for the numerical solution of the Poisson-Boltzmann equation (PBE), one of the most popular continuum models for describing electrostatic interactions between molecular solutes in salty, aqueous media. Continuum electrostatics plays an important role in several areas of biomolecular simulation, including simulation of diffusional processes to determine ligand-protein and protein-protein binding kinetics, implicit solvent molecular dynamics of biomolecules, solvation and binding energy calculations to determine ligand-protein and protein-protein equilibrium binding constants and aid in rational drug design, and biomolecular titration studies.
View3D is a program to calculate radiation view factors, as used in radiant heat transfer problems in mechanical engineering, building design, furnace design, etc. Data input is via text file. There are 3D and 2D viewers for checking your input. View factors are output to another file for use with other calculation tools. View factors are also sometimes called "shape factors", "configuration factors", and "form factors".
Powua is a parallel super-computer consisting of many processors that work simultaneously. The Powua client lets users access this high computing power from wherever they are, directly on their computer, through a simple Internet connection. If your preferred software is supported, you can start using it immediately in Powua and speed up all those processes that would otherwise occupy your processor for a long time. Powua subdivides your operation and distributes it to many processors simultaneously.
Enter the ambient world of Osmos: elegant, physics-based gameplay, dreamlike visuals, and a minimalist, electronic soundtrack. Your objective is to grow by absorbing other motes. Propel yourself by ejecting matter behind you. But be wise: ejecting matter also shrinks you. Relax; good things come to those who wait. Progress from serenely ambient levels into varied and challenging worlds. Confront attractors, repulsors, and intelligent motes with similar abilities and goals as you. It is 100% DRM and region free, and features procedural generation (play random versions of any level) and an electronic soundtrack by Loscil, Gas/High Skies, Julien Neto, Biosphere, and more.
pyXSD maps XML and XSD (XML Schema) files into Python, checks the XML against the schema, and transforms XML documents according to user-specified Python classes. There is a framework to make these transformation classes easy to write. The program uses a simple, pythonic, non-DOM interface with the XML tree structure.
