Weak signal ham radio communication
The WSJT project currently includes five programs designed for amateur radio communication using state of the art digital techniques. Typical applications include meteor scatter, EME ("moonbounce"), and QRP communication at HF. Summary Program Descriptions: WSJT: Modes JTMS, FSK441, ISCAT, JT6M, JT65, JT4, Echo, CW. Optimized for meteor scanner, ionospheric scatter, and EME at VHF/UHF/Microwaves. WSJT-X: Modes JT65, JT9. Primarily for use at HF. MAP65: For EME an VHF and higher frequencies. Implements a panoramic, polarization-matching receiver for JT65. WSPR: Probe potential propagation paths using low-power transmissions. WSPR-X: Experimental version of WSPR, including the slow mode WSPR-15. Source code is maintained here SourceForge. For installable end-user packages please go to the WSJT web site at the link below.
A full featured cross-platform image library
Developer's Image Library (DevIL) is a cross-platform image library utilizing a simple syntax to load, save, convert, manipulate, filter and display a variety of images with ease.
Source Navigator NG is a source code analysis tool. With it, you can edit your source code, display relationships between classes and functions and members, and display call trees. You can navigate your source code and easily get to declarations or implementations of functions, variables and macros (commonly called "symbols") which helps you discovering and mapping unknown source code for enhancement or maintenance tasks.
APBS is a software package for the numerical solution of the Poisson-Boltzmann equation, a popular continuum model for describing electrostatic interactions between molecular solutes over a wide range of length scales. <http://www.poissonboltzmann.org/>.

Towhee is a Monte Carlo molecular simulation code originally designed for the prediction of fluid phase equilibria using atom-based force fields and the Gibbs ensemble with particular attention paid to algorithms addressing molecule conformation sampling.
AUTO is a publicly available software for continuation and bifurcation problems in ordinary differential equations originally written in 1980 and widely used in the dynamical systems community.
This is a port of the ebe programming environment to QT.
The ebe programming environment is a nice IDE designed for developing Assembly programs. It also handles C and C++ programs as well since there was not much extra effort. It used to support Fortran and this could return if people want Fortran. This project is an effort to recode ebe using C++ and QT. Originally ebe was coded using Python, Tkinter and Pmw, which worked out pretty well. The QT environment offers substantially better GUI controls. The most obvious difference is that Python ebe has a lot of separate windows, while the QT ebe will use 1 main window and a collection of dockable subwindows. This will make it easier to use.
This site hosts the source code for C++ version of the Broker for SBW, NOM module, advanced simulation suite, analysis applications and model editors.
MMTL, the Multilayer Multiconductor Transmission Line 2-D and 2.5-D electromagnetic modeling tool suite, generates transmission parameters and SPICE models from descriptions of electronics interconnect dimensions and materials properties.
Algae is a programming language for numerical analysis. We wrote it because we needed a fast and versatile tool, capable of handling large systems. Algae has been applied to interesting problems in aerospace and related fields for more than a decade.
PUPIL (Program for User Package Interface and Linking), is a software environment that allows developers to link quickly and efficiently together multiple pieces of software in a fully automated multi-scale simulation. More specifically, it supports QM/MM MD simulations where the user might choose among any of the different MD engines and QM engines, which are connected to PUPIL as external programs through a tiny specific interface. One of the main advantages here is that the user can use most of the functionalities that may have those external programs interfaced without the necessity to be reimplemented again on independent interfaces. In fact, this simulation interface concentrates all the common code involved in the coupling terms of the QM/MM approach.
The Open-source Pseudopotential Interface / Unification Module (OPIUM) allows to generate pseudopotentials in an interactive way, perform ghost checks, Kleinman-Bylander transformation, and output in many different pseudopotential file formats.

UPS is a source level C, C++ and Fortran debugger with an X windows interface. It's a very light debugger, but is quite efficient and works well. An ANSI compliant C interpreter is included.
A package of programs for performing extended Hueckel calculations on molecules and solids and visualizing the results. Visualization functionality for some quantum packages (ADF and LMTO) is also provided.
Intellect Modeling Kit - full intellect-based apps development suite
Intellect Modeling Kit is an alternative to traditional Artificial Intelligence, intended to build apps assisting human intellect on the steps of its activity: * Observation * Producing propositions based on knowledge * Elimination of impossible propositions * Selection and verification of the most appropriate propositions * Memorizing - converting data to information and new knowledge item creation * Abstraction finding – building artificial objects, representing group of real objects featuring typical signs of group Any human knowledge written and spoken can be uploaded to IMK in a straight way by any expert not familiar with software coding. The IMK components are designed to create ready-to-use software application using simple text files provided by people. IMK accepts human knowledge and develops new knowledge together with people. The activity of IMK could be verified by human expert on every stage. IMK assists intellectual activity, but does not replace us.
