Enterprise project management and alternative to Project Server
]project-open[ is Web based enterprise project management application with a focus on finance and collaboration. It’s main purpose is to coordinate the work of project managers, project members and stake holders across multiple projects. Target organizations are companies or corporate departments that need to track finances, tasks, and resources for a large number of concurrently running projects. ]project-open[ consists of about 200 modules for resource management, time sheet management, HR, CRM, ITSM, collaboration and financials. ]po[ is built on top of OpenACS.org, an open-source Web platform featuring role-base permissions, workflows, dynamically extensible objects and full-text search.
Library to control radio transceivers and receivers
The Hamlib project's purpose is to develop flexible and portable shared libraries that offer a standardized API to control any radio oriented equipment through a computer interface.
Project moved to https://github.com/owfs/owfs/
Please note that OWFS source code, and all Issue/Tickets/merge requests have now been moved to https://github.com/owfs/owfs/. Developer mailing lists will still be kept at Sourceforge. ---- OWFS -- 1-Wire file system. Use the Dallas 1-Wire and iButton chips with standard filesystem commands. Create temperature loggers. Monitor everything. OWHTTPD -- same system, only used as a light weight web server. OWFS is also ported to embedded routers, Mac OSX and Windows. Basically you can use these inexpensive little sensors and other chips with very simple wiring to sense and control the physical environment. The interface is very flexible -- everything from a web browser, to read and writing directly to the chip's "file" to integrating with your programs -- even over the internet. There is a growing number of 1-wire sensors: temperature, voltage, humidity, light, ultraviolet, pressure, thermisters, thermocouples, programmable microcontrollers, relays, lights, LCD panels, etc
Video mixer for mixing live and recorded video and audio feeds
New version 0.5.1 Released February 9th 2016. Snowmix is a Swiss army knife tool for mixing live and recorded video and audio feeds. It supports 2D and 3D clipping, scaling and transparent overlay of video, png graphics and text. It supports animation of video, images and texts through native commands changing scale, placement, transparency and rotation. Animation and actions can also be controlled through native scripting and an embedded Tcl interpreter. Snowmix is designed for control over low bandwidth links and can work as a standalone CLI based program. Control over both CLI and a TCP connections. Input and outputs can be done through GStreamer pipelines or the GStreamer shmsrc/shmsink API. OS X on Intel and Linux on amd64/i386/i686/ARMv7 and FreeBSD on amd64 supported. Ubuntu/Fedora/Mint/Debian/Chakra/CentOS/OpenSUSE and Linero is supported. Free support in the discussion forum. See Snowmix in action on Youtube http://www.youtube.com/user/Snowmix4video

Coccinella is a free and open-source cross-platform communication tool with a built-in whiteboard for improved collaboration with other people.
System dynamics program with additional features for economics
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
CECILIA is an environment for music and signal-processing that uses Csound as its underlying audio processing engine. One can think of CECILIA as a completely programmable sound-processing tool, with real-time interactive processing on soundfiles or live

Localisation system in wireless sensor networks using ns-2
This project presents an extension to ns-2, which enables a normal user, who has basic knowledge of ns-2, to simulate localization system within a wireless network. Moreover, this project would be beneficial to researchers who want to implement new or existing localisation algorithms and anyone new to ns-2 who wish to know more about how a simulation project is built and structured. , provide more details.
