  2. Gaussian curvature - Wikipedia

    en.wikipedia.org/wiki/Gaussian_curvature

    When a surface has a constant zero Gaussian curvature, then it is a developable surface and the geometry of the surface is Euclidean geometry.. When a surface has a constant positive Gaussian curvature, then the geometry of the surface is spherical geometry.

    Visualization of the whole observable universe.The inner blue ring indicates the approximate size of the Hubble volume. In cosmology, a Hubble volume (named for the astronomer Edwin Hubble) or Hubble sphere, subluminal sphere, causal sphere and sphere of causality is a spherical region of the observable universe surrounding an observer beyond which objects recede from that observer at a rate ...

  5. Volumetric mesh - Wikipedia

    en.wikipedia.org/wiki/Volumetric_mesh

    One application of volumetric meshes is in finite element analysis, which may use regular or irregular volumetric meshes to compute internal stresses and forces in an object throughout the entire volume of the object. [1] Volume meshes may also be used for portal rendering.

  6. Quantum volume - Wikipedia

    en.wikipedia.org/wiki/Quantum_volume

    The quantum volume of a quantum computer was originally defined in 2018 by Nikolaj Moll et al. [10] However, since around 2021 that definition has been supplanted by IBM's 2019 redefinition. [ 11 ] [ 12 ] The original definition depends on the number of qubits N as well as the number of steps that can be executed, the circuit depth d

    where p is the pressure, V is volume, n is the polytropic index, and C is a constant. The polytropic process equation describes expansion and compression processes which include heat transfer. The polytropic process equation describes expansion and compression processes which include heat transfer.

    TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)
