  4. Streaming algorithm - Wikipedia

    en.wikipedia.org/wiki/Streaming_algorithm

    Streaming algorithm. In computer science, streaming algorithms are algorithms for processing data streams in which the input is presented as a sequence of items and can be examined in only a few passes, typically just one. These algorithms are designed to operate with limited memory, generally logarithmic in the size of the stream and/or in the ...

  6. Cathode ray - Wikipedia

    en.wikipedia.org/wiki/Cathode_ray

    Cathode ray. A beam of cathode rays in a vacuum tube bent into a circle by a magnetic field generated by a Helmholtz coil. Cathode rays are normally invisible; in this demonstration Teltron tube, enough gas has been left in the tube for the gas atoms to luminesce when struck by the fast-moving electrons. Cathode rays or electron beams ( e-beam ...

    The ten-rays model is a mathematical model applied to the transmissions of radio signal in an urban area, to generate a model of ten rays typically four rays more are added to the six rays model, these are ( and bouncing on both sides of the wall); This incorporate paths from one to three reflections: specifically, there is the LOS ( Line of ...

  8. Geometrical optics - Wikipedia

    en.wikipedia.org/wiki/Geometrical_optics

    Geometrical optics. Geometrical optics, or ray optics, is a model of optics that describes light propagation in terms of rays. The ray in geometrical optics is an abstraction useful for approximating the paths along which light propagates under certain circumstances. The simplifying assumptions of geometrical optics include that light rays:

  9. Rutherford scattering - Wikipedia

    en.wikipedia.org/wiki/Rutherford_scattering

    It received enough kinetic energy in the elastic collision to cause a short visible recoiling track near point 2. (The scale is in centimeters.) In particle physics, Rutherford scattering is the elastic scattering of charged particles by the Coulomb interaction. It is a physical phenomenon explained by Ernest Rutherford in 1911 [1] that led to ...
