  2. Tower defense - Wikipedia

    en.wikipedia.org/wiki/Tower_defense

    All Star Tower Defense (ASTD) has also gained popularity, incorporating anime characters as towers, while Tower Blitz is known for its futuristic setting and unique enemy designs. A more recent addition to the Roblox tower defense scene is Tower Defense X (TDX). This game builds upon the classic tower defense formula with advanced mechanics ...

  3. Rayleigh distribution - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_distribution

    The distribution is named after Lord Rayleigh (/ ˈ r eɪ l i /). [1] A Rayleigh distribution is often observed when the overall magnitude of a vector in the plane is related to its directional components. One example where the Rayleigh distribution naturally arises is when wind velocity is analyzed in two dimensions.

  4. Angular resolution - Wikipedia

    en.wikipedia.org/wiki/Angular_resolution

    The result, θ = 4.56/D, with D in inches and θ in arcseconds, is slightly narrower than calculated with the Rayleigh criterion. A calculation using Airy discs as point spread function shows that at Dawes' limit there is a 5% dip between the two maxima, whereas at Rayleigh's criterion there is a 26.3% dip. [ 3 ]

  5. Rayleigh scattering - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_scattering

    Rayleigh scattering of that light off oxygen and nitrogen molecules, and; the response of the human visual system. The strong wavelength dependence of the Rayleigh scattering (~λ −4) means that shorter wavelengths are scattered more strongly than longer wavelengths. This results in the indirect blue and violet light coming from all regions ...

  6. Rayleigh–Ritz method - Wikipedia

    en.wikipedia.org/wiki/Rayleigh–Ritz_method

    In numerical linear algebra, the Rayleigh–Ritz method is commonly [12] applied to approximate an eigenvalue problem = for the matrix of size using a projected matrix of a smaller size <, generated from a given matrix with orthonormal columns. The matrix version of the algorithm is the most simple:

  7. Tonelli–Shanks algorithm - Wikipedia

    en.wikipedia.org/wiki/Tonelli–Shanks_algorithm

    The Tonelli–Shanks algorithm (referred to by Shanks as the RESSOL algorithm) is used in modular arithmetic to solve for r in a congruence of the form r 2 ≡ n (mod p), where p is a prime: that is, to find a square root of n modulo p.

  8. Rayleigh–Jeans law - Wikipedia

    en.wikipedia.org/wiki/Rayleigh–Jeans_law

    Comparison of Rayleigh–Jeans law with Wien approximation and Planck's law, for a body of 5800 K temperature.. In physics, the Rayleigh–Jeans law is an approximation to the spectral radiance of electromagnetic radiation as a function of wavelength from a black body at a given temperature through classical arguments.

  9. Rayleigh wave - Wikipedia

    en.wikipedia.org/wiki/Rayleigh_wave

    The typical speed of Rayleigh waves in metals is of the order of 2–5 km/s, and the typical Rayleigh speed in the ground is of the order of 50–300 m/s for shallow waves less than 100-m depth and 1.5–4 km/s at depths greater than 1 km. Since Rayleigh waves are confined near the surface, their in-plane amplitude when generated by a point ...
