  2. High-availability Seamless Redundancy - Wikipedia

    en.wikipedia.org/wiki/High-availability_Seamless...

    An HSR network node (DANH) has at least two Ethernet ports, each attached to a neighbour HSR node, so that always two paths exist between two nodes. Therefore, as long as one path is operational, the destination application always receives one frame. HSR nodes check the redundancy continuously to detect lurking failures.

  3. Ramsauer–Townsend effect - Wikipedia

    en.wikipedia.org/wiki/Ramsauer–Townsend_effect

    The probability of scattering in such a system is defined as the number of electrons scattered, per unit electron current, per unit path length, per unit pressure at 0 °C, per unit solid angle. The number of collisions equals the total number of electrons scattered elastically and inelastically in all angles, and the probability of collision ...

  4. Shape resonance - Wikipedia

    en.wikipedia.org/wiki/Shape_resonance

    More simply, the shape resonance total energy is more than the separated fragment energy. [8] Practical implications of this difference for lifetimes and spectral widths are mentioned in works such as Zobel. [9] Related terms include a special kind of shape resonance, the core-excited shape resonance, and trap-induced shape resonance. [10]

  5. Optical ring resonators - Wikipedia

    en.wikipedia.org/wiki/Optical_ring_resonators

    [8] [9] These nested ring resonators are designed to enhance the quality factor (Q-factor) and extend the effective light-matter interaction length. These nested cavity configurations enable light to traverse the nested cavity multiple times, a number equal to the round trips of the main cavity multiplied by the round trips of the nested cavity ...

  6. Resonance (particle physics) - Wikipedia

    Thus, the lifetime of a particle is the direct inverse of the particle's resonance width. For example, the charged pion has the second-longest lifetime of any meson, at 2.6033 × 10 −8 s. [2] Therefore, its resonance width is very small, about 2.528 × 10 −8 eV or about 6.11 MHz. Pions are generally not considered as "resonances".

  7. Triple-resonance nuclear magnetic resonance spectroscopy

    en.wikipedia.org/wiki/Triple-resonance_nuclear...

    Triple resonance experiments are a set of multi-dimensional nuclear magnetic resonance spectroscopy (NMR) experiments that link three types of atomic nuclei, most typically consisting of 1 H, 15 N and 13 C. These experiments are often used to assign specific resonance signals to specific atoms in an isotopically-enriched protein.

  8. Resonant trans-Neptunian object - Wikipedia

    en.wikipedia.org/wiki/Resonant_trans-Neptunian...

    In astronomy, a resonant trans-Neptunian object is a trans-Neptunian object (TNO) in mean-motion orbital resonance with Neptune.The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune, e.g. 1:2, 2:3, etc. Resonant TNOs can be either part of the main Kuiper belt population, or the more distant scattered disc population.

  9. Dual resonance model - Wikipedia

    en.wikipedia.org/wiki/Dual_resonance_model

    The study of dual resonance models was a relatively popular subject of study between 1968 and 1973. [5] It was even taught briefly as a graduate level course at MIT, by Sergio Fubini and Veneziano, who co-authored an early article. [ 6 ]
