Stellarium is a free GPL software which renders realistic skies in real time with OpenGL. It is available for Linux/Unix, Windows and macOS. With Stellarium, you really see what you can see with your eyes, binoculars or a small telescope. Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. Plugin system adding artifical satellites, ocular simulation, telescope control and more. Ability to add new solar system objects from online resources. Add your own deep sky objects, landscapes, constellation images, scripts, etc. Supernovae and novae simulation. Exoplanet locations. 3D sceneries. Skinnable landscapes with spheric panorama projection.

A free cross-platform library of fast C++ routines for the plotting of up to 3-ranged data. It can export to bitmap and vector EPS/SVG files. There are window interfaces (GLUT/FLTK/Qt) and console tools. MathGL can be used from C/Fortran/Python/Octav/Lua

An opensource typesetting environment for editing and publishing Carnatic music books in Indian languages. Supports Phonetic Translation of notation & lyrics and uses CFugue Runtime to automatically generate MIDI song files from the music notation.

libtdms is a C++ library for reading National Instruments TDMS files (http://www.ni.com/white-paper/3727/en).

The toolkit glpk supports methods for mixed integer linear programming (MILP). These methods solve Capital Budgeting Problems (CBP). Unfortunately, glpk does not support any multithreading and there is no feature to distribute problems via network connections. Today, this is a pitiable sight, because modern computer systems are coupled by networks and support multi threading. We create a distributed system with Apache thrift and the C-API of glpk. Now, it is possible to use as many cores in a network as you want. With a focus on the MILP methods we implement a load balancing and speed up the solving process in a multiplicative way. Sometimes we have super-linear speedup with a small set of hardware. With a splitting of problems, parallel computing and distributing the actual best solution to all running processes we solve CBP much faster than a sequential processing can do.

The repertory grid interviewing technique was developed as a way to systematically examine how individuals or groups perceive knowledge, their problems, organisation, service provision, etc while avoiding interviewer distortions. Enquire Within provides a clear structure for the process, leading the interviewer through the steps and disciplines required to set up a successful interview and then prompts the interviewer with carefully constructed questions to facilitate comparing and contrasting elements related to the purpose of the interview. Responses are progressively recorded and can, as required, be analysed for the purpose of constructing further compare and contract questions to gain more granularity. While the repertory grid interview can be carried out manually it is not possible to carry out dendritic analysis of the results on the fly without interrupting the flow of the interview. Enquire Within enables that.

Flatland is the virtual environment developed to perform these investigations. Using Flatland as the base environment scientists can visualize and explore both their data and the computations that manipulate that data. Imagine, if you will, a scientist able to examine the real-time results of a simulation and, when he notices an anomally he would like to investigate, he turns to the program running the simulation and examines the code, possibly changing it on the fly. This is the dream of Flatland.

MBDyn_sim_suite is a collection of free pre&post-processing tools and simulation models for the open-source multi-body analysis software MBDyn forming a general purpose simulation environment for structural dynamics with an emphasis on wind turbines.

QNANWidgets is a collection of science/engineering oriented Qt Widgets to help in creating sci/eng. applications and include a chart and plot widget. The widgets are easy to use and can be customized in Qt Designer directly.

ENGLISH: This Sofftware is an application built to help people deal with their multiple Pdf files or ebooks in Pdf format and is extremely simple to use with a minimalistic interface. proper those people who do not like spending much time learning how an application functions. When the reader starts it, he needs to select the directory (folder) which contains the directories with the files, next the interface opens and it starts performing the magic. PORTUGUÊS Este software permite o usuário organizar os seus ficheiros no formato Pdfs ou ebooks. Ele é muito símples com uma interface minimalista para facilitar o usuário. Tudo o que o utilizador precisa fazer é apenas escolher o directório (pasta) que contem os directórios onde os Pdfs estão armazenados. A seguir é a magia do software.
