American Political Science: Campaign Simulator project is a statistically based political campaign simulation game.
The Campaign Simulator is an attempt to statistically model and predict the outcome of an American presidential election.
Several users assume the roles of competitive candidates and inflict the repercussions of certain decisions on a GSS-based dataset.
The application is written in Java and supports all operating systems with a Java 1.5 VM.
Main features:
- Time is not the only limiting variable. In fact, time may not be the proper limit as most operations may be performed in tandem; an economic system that allows fund raising elements should be implemented.
- The current choices all utilize the same dataset algorithm to effect the populace in similar ways- this set of scripts should be broadened and deepened as they are too high level.
- The Python Architecture needs polishing- the internal IDE is not complete, and the ability to assign scripts to run at differing points in the lifetime of the application has yet to be created.
- The installer should place links on the desktops of Mac and Unix/Linux Systems.
- Some of the small features planned, such as a GUI for dialog creation, have been cut for the deadline and should be added.

CCFlauncher is the meta-tool for starting and joining a CCF collaborative computing session. With CCFlauncher you can invite your colleagues/friends to join you in a shared X windows virtual desktop with multiparty audio conferencing, white board, and file sharing in just a few mouse clicks. In this setting, participants interact with each other, simultaneously access and operate computer applications, refer to global data repositories or archives, collectively create and manipulate documents or other artifacts, perform computational transformations, and conduct a number of other activities via telepresence. Research issues addressed in this project include problem solving environments and methodologies for laboratory and instrument-based scientific disciplines, and computer science issues in heterogeneous distributed systems. New approaches are being investigated and developed for fast multiway communication, robust geographically distributed data management methodologies, high-performance computational transforms inlined within collaboration sessions, and related auxiliary issues such as active documents, security, archival storage, and experiment management and control.

The main goal of CCF is to enable the construction of efficient and flexible collaborations. Although we expect that CCF will be useful in a number of scenarios, a guiding principle in its design was to identify and meet the needs of natural science investigators with a diverse set of computing, instrument interfacing, and collaboration requirements. Thus, the primary target domain for CCF is collaborative research in chemistry, physics, and biochemistry, and closely related areas. Research methodology in laboratory and instrument based sciences is increasingly dependent upon computation, interaction, visualization, and data storage/retrieval. The CCF project is investigating and developing innovative enabling technologies to support collaborative, distributed, computer-based problem solving in the natural sciences. The goal is to evolve a virtual environment for distributed computing that integrally supports human AV communication, high performance heterogeneous computing, and distributed data management facilities. Computational transforms, instrument interfacing, data referral, visualization, and collaborative work in chemistry, physics, and biomedical fields will guide the development of methodologies and software tools to facilitate collaborative research.

ASCEND is a flexible modelling environment for solving hard engineering and science problems. It offers:
- an object-oriented model description language for describing your system,
- an interactive user interface that allows you to solve your model and explore the effect of changing the model parameters, and
- a scripting environment that allows you to automate your more complex simulation problems.
The project was originally written at Carnegie Mellon University in the 1980s and includes powerful and reliable solver routines that analyse the structure of your model and can solve thousands of simultaneous nonlinear equations in a few seconds on everyday computer hardware. It is under active development and is licensed under the GNU General Public License ensuring that it is free software and will remain free.

GiNaC is an iterated and recursive acronym for GiNaC is Not a CAS, where CAS stands for Computer Algebra System. It is designed to allow the creation of integrated systems that embed symbolic manipulations together with more established areas of computer science (like computation- intense numeric applications, graphical interfaces, etc.) under one roof. It is distributed under the terms and conditions of the GNU general public license (GPL).
The project has been specifically developed to become a replacement engine for xloops which is up to now powered by the Maple CAS. However, it is not restricted to high energy physics applications. Its design is revolutionary in a sense that contrary to other CAS it does not try to provide extensive algebraic capabilities and a simple programming language but instead accepts a given language (C++) and extends it by a set of algebraic capabilities.
Enhancements:
- Bugs in fderivative::match_same_type(), expairseq::match(), expand_dummy_sum(), and expairseq::map() have been fixed, and the C source output has been slightly improved.
- Problems when compiling with GCC 4.2 have been resolved.

Scilab project is a is a numerical computation system similiar to Matlab or Simulink.

Scilab is an open source numerical computation platform developed by a consortium managed by INRIA (French National Institute for Research in Computer Science and Control) which, to date, gathers 23 industrial companies, research centers and engineer schools. It provides a powerful environment for the development of scientific applications and for engineering. Each month, nearly 20,000 remote downloads of
Scilab are registered from the Internet site of the Consortium, which takes Scilab one of the most valued pieces of open source scientific oftware.

Mandriva, whose membership to the Scilab Consortium is pending, and he Scilab Consortium agreed to integrate Scilab into the new Mandriva Linux 2007 distribution (Discovery, Powerpack and Powerpack+). The development teams of Scilab and Mandriva cooperated in the integration f the latest version of Scilab (v4.0, announced in February 2006 and since downloaded more than 150,000 times) into this new Mandriva release. It is planned to continue this arrangement for future versions of Mandriva Linux and of Scilab. In addition, Scilab will also be integrated into Corporate Desktop 4, the Mandriva Linux workstation for businesses.

About The Scilab Consortium

The Scilab software is, since May 2003, produced by a consortium, managed by INRIA, which, to date, has 23* industrial companies, research centers and engineering schools as members. The creation of the Scilab Consortium reflects a will to produce an open source numerical computation platform of high quality. Scilab is developed by a dedicated and permanent team hosted by INRIA. Moreover, its open source nature allows external contributions and thus a level of know-how in the field of scientific computation can be reached which a single company could otherwise claim only with difficulty. Nearly 20,000 remote downloads of the Scilab software are carried out each month from the official site of the Consortium to the benefit of European and foreign companies, universities and research centers. The
membership of the Scilab Consortium is in constant growth.

Greenstone is a suite of software for building and distributing digital library collections. It provides a new way of organizing information and publishing it on the Internet or on CD-ROM.
Greenstone is produced by the New Zealand Digital Library Project at the University of Waikato, and developed and distributed in cooperation with UNESCO and the Human Info NGO.
Greenstone is open-source, multilingual software, issued under the terms of the GNU General Public License.
The aim of the Greenstone software is to empower users, particularly in universities, libraries, and other public service institutions, to build their own digital libraries. Digital libraries are radically reforming how information is disseminated and acquired in UNESCOs partner communities and institutions in the fields of education, science and culture around the world, and particularly in developing countries. We hope that this software will encourage the effective deployment of digital libraries to share information and place it in the public domain.

JChemPaint project is an editor for 2D molecular structures.
JChemPaint is intended to be complementary to Jmol, a visualisation and analysis tool for 3D molecular structures, started by Dan Gezelter at Notre Dame University, initator of the Open Science Project. and, like JChemPaint, developed by an international team of opensource programmers.
Main features:
- JChemPaint is open source OS. It is Free Software. We believe that scientific software, especially when its development was publically funded, should be free. As the GNU people put it: "``Free software is a matter of liberty, not price. To understand the concept, you should think of free speech, not free beer. ". Everyone can participate in the development of the program. Everyone can download and change the source code, provided that he makes the changes publicly available again, according to the GNU Lesser General Public License, LGPL. This ensures that the community can take advantage of any bugfix/enhancement made to the system.
- It also ensures that a scientist, who needs a standard piece of software like a structure editor as a helper application in her new program, does not have to reinvent the wheel over and over again because all the structure editors that have been written before are now proprietory software. If there is a free structure editor, she can focus on the real science.
- JChemPaint is not complete :-). Honestly, it can still use a lot of development (see below).
- Since JChemPaint is written in Java it runs on any computing platform and operating system for which a Java Virtual Machine (of version >= 2) has been implemented (like Linux, Windows 95/98/NT, Solaris, AIX and others).
- JChemPaint is avaiblable free of charge.
- JChemPaint is translated into several languages: Dutch, French, German and Polish.
Enhancements:
- This release is a build from the latest of CDK SVN.
- It adds InChI support and a SMILES entering field with memory.
- Many bugs were fixed, and the program should be faster too.
