| Carbon Footprint Calculator |
 879 kB |
 all |
| Calculate your carbon footprint with this easy to use calculator software. Enter in data to figure CO2 generated from activities including transportation, energy, trash or waste, recreation, purchasing habits, food, and more. Lear n where you can go green by calculating your carbon footprint and then focusing on areas where you can make the most positive impact on the environment. The software gives you CO2 footprint details from each category. For transportation you can enter in up to 6 different cars and their respective fuel efficiency, airline travel, bus travel, and rail travel. To figure your energy use and carbon footprint, you can enter in your location, number of people in your house, as well as energy use from fuel oil, natural gas, and electricity. Also included are indirect carbon footprint categories like recreation habits, purchasing habits, waste, recycling participation, food, and more. Different units are available so you can calculate your carbon footprint in metric units or English. You can also print out a summary of your carbon footprint results. | ||
| QSpider |

| Project QSpider started on December, 19th, 2007. The project purpose is working out of free software QSpider for modelling mechanical systems (robots, mechanisms of parallel kinematics). QSpider is a free program for engineers and researchers. You also can will join work on the program. Features of QSpider: - Mathematical modelling of spatial mechanisms with use of multilevel representation of mechanical systems. The given approach allows to simplify and reduce time of construction of models considerably. - Modelling of auxiliary elements of the equipment, for example, the rotary tables, special adaptations, etc. - The main feature of the program is global parameterisation of model. Any of model parametres can set a variable. The program allows to enter defined a mathematical parity in the form of mathematical expressions and to modify all model at change of another or other sizes (parametres) of model. - Construction of constructive elements of mechanisms (the basis, a platform, a bed, etc.). - Independent sources of the program. The program is developed on C++ with use of free version Qt. QSpider works under control of operational systems: Windows, Linux and MacOS. |

| Engauge Digitizer |
7.0 MB |
all |
| This open source, digitizing software converts an image file showing a graph or map, into numbers. The image file can come from a scanner, digital camera or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. The process starts with an image file containing a graph or map. The final result is digitized data that can be used by other tools such as Microsoft Excel and Gnumeric. | ||

ME/2000/XP/2003 |
| See the brightest 2500 stars, all 88 constellations, all nine planets and the moonphase from 1600 AD to 9999 AD from any location on earth. Click star on screen for detailed information. Geocentric and heliocentric views also available. Define your own five locations for quick switch. Tiny program, but great planetarium, especially for teachers and students. Print todays night sky ! Nice visuals, smooth animation, simple controls, good planet data. This is the Windows version of the classic Planetarium software of 1992. The DOS version didn't work with todays fast computer anymore. But it was downloaded for 13 years, and one of the first of its kind, especially the animantions and colors. If you need a quick overview when and where a planet, star is, this is your perfect joice. And it is really for free, no registration required. So try it and see yourself! | ||

| GrandTour |

3.1/95/98/NT/ME/2000/XP/2003 |
| GRANDTOUR can simulate space as seen from the Voyager and Giotto spacecraft. In addition, GRANDTOUR can generate scenes from arbitrary points in space or the Earth, with the spacecraft visible to the observer. The planet, moons, and rings of interest (or comet, nucleus, and tail), stars, the sun, and the spacecraft are all accurately drawn with wireframe representations. Hidden line removal is done for the body surfaces. The motions of the bodies themselves are highly accurate, with errors no greater than 500 kilometers. The user has considerable control over the time step, field of view, etc., and many frames per second are typically generated. The program was originally developed at the Jet Propulsion Laboratory by John D. Callahan to assist in the analysis of science and optical navigation data. In addition, the program was filmed by the BBC as part of a NOVA documentary on the Voyager Uranus encounter, and by the Four Point Entertainment Company for a commercially available video on Halley's Comet. Program conveniently runs from any Windows/DOS. | ||
