  2. Radioactive tracer - Wikipedia

    en.wikipedia.org/wiki/Radioactive_tracer

    A radioactive tracer, radiotracer, or radioactive label is a synthetic derivative of a natural compound in which one or more atoms have been replaced by a radionuclide (a radioactive atom). By virtue of its radioactive decay, it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from ...

  3. Radioisotope thermoelectric generator - Wikipedia

    en.wikipedia.org/wiki/Radioisotope...

    A radioisotope thermoelectric generator (RTG, RITEG), sometimes referred to as a radioisotope power system (RPS), is a type of nuclear battery that uses an array of thermocouples to convert the heat released by the decay of a suitable radioactive material into electricity by the Seebeck effect. This type of generator has no moving parts and is ...

  4. Gallium-68 generator - Wikipedia

    en.wikipedia.org/wiki/Gallium-68_generator

    The parent isotope germanium-68 is the longest-lived (271 days) of the radioisotopes of germanium. It has been produced by several methods. [1] In the U.S., it is primarily produced in proton accelerators: At Los Alamos National Laboratory, it may be separated out as a product of proton capture, after proton irradiation of Nb-encapsulated gallium metal. [2]

    List of ray tracing software. Ray tracing is a technique that can generate near photo-realistic computer images. A wide range of free software and commercial software is available for producing these images. This article lists notable ray-tracing software. Software.

  6. Cube mapping - Wikipedia

    en.wikipedia.org/wiki/Cube_mapping

    In computer graphics, cube mapping is a method of environment mapping that uses the six faces of a cube as the map shape. The environment is projected onto the sides of a cube and stored as six square textures, or unfolded into six regions of a single texture. The cube map is generated by first rendering the scene six times from a viewpoint ...

  7. POV-Ray - Wikipedia

    en.wikipedia.org/wiki/POV-Ray

    AGPL-3.0-or-later [5] Website. www.povray.org. The Persistence of Vision Ray Tracer, most commonly acronymed as POV-Ray, is a cross-platform ray-tracing program that generates images from a text-based scene description. It was originally based on DKBTrace, written by David Kirk Buck and Aaron A. Collins for Amiga computers.

  8. Pantograph - Wikipedia

    en.wikipedia.org/wiki/Pantograph

    Pantograph 3d rendering. A pantograph (from Greek παντ- 'all, every' and γραφ- 'to write', from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by ...

  9. Rubidium-82 - Wikipedia

    en.wikipedia.org/wiki/Rubidium-82

    The decay of Rubidium-82, which undergoes positron emission.. Rubidium-82 is produced by electron capture of its parent nucleus, strontium-82.The generator contains accelerator produced 82 Sr adsorbed on stannic oxide in a lead-shielded column and provides a means for obtaining sterile nonpyrogenic solutions of rubidium chloride (halide salt form capable of injection).
