  2. Head (vessel) - Wikipedia

    en.wikipedia.org/wiki/Head_(Vessel)

    The dish has a radius that equals the diameter of the cylinder it is attached to (=). The knuckle has a radius that equals a tenth of the diameter of the cylinder ( r 2 = 0.1 × D o {\displaystyle r_{2}=0.1\times Do} ), hence its alternative designation "decimal head".

  4. Universal Satellites Automatic Location System - Wikipedia

    en.wikipedia.org/wiki/Universal_Satellites...

    USALS is a program and not a communication protocol. The USALS calculates the dish angular position given by the dish longitude/latitude and the position of the satellite in geostationary orbit. It then sends the angular position to the positioner using the DiSEqC 1.2 protocol. This calculation is straight on using geometric calculations.

  5. List of open-source software for mathematics - Wikipedia

    en.wikipedia.org/wiki/List_of_open-source...

    An unpublished computational program written in Pascal called Abra inspired this open-source software. Abra was originally designed for physicists to compute problems present in quantum mechanics. Kespers Peeters then decided to write a similar program in C computing language rather than Pascal, which he renamed Cadabra. However, Cadabra has ...

    en.wikipedia.org/wiki/Abaqus

    Abaqus FEA [4] [5] (formerly ABAQUS) is a software suite for finite element analysis and computer-aided engineering, originally released in 1978. The name and logo of this software are based on the abacus calculation tool. [6] The Abaqus product suite consists of five core software products: [5]

  8. Antenna boresight - Wikipedia

    en.wikipedia.org/wiki/Antenna_boresight

    For most antennas the boresight is the axis of symmetry of the antenna. For example, for axial-fed dish antennas, the antenna boresight is the axis of symmetry of the parabolic dish, and the antenna radiation pattern (the main lobe) is symmetrical about the boresight axis. Most antennas boresight axis is fixed by their shape and cannot be changed.

    CYANA (combined assignment and dynamics algorithm for NMR applications) is a program for automated structure calculation of biological macromolecules on the basis of conformational constraints from nuclear magnetic resonance (NMR).
