  2. EIDORS - Wikipedia

    en.wikipedia.org/wiki/EIDORS

    EIDORS is an open-source software tool box written mainly in MATLAB/GNU Octave designed primarily for image reconstruction from electrical impedance tomography (EIT) data, in a biomedical, industrial or geophysical setting. The name was originally an acronym for Electrical Impedance Tomography and Diffuse Optical Reconstruction Software.

  3. Track circuit - Wikipedia

    en.wikipedia.org/wiki/Track_circuit

    In electrified areas, jointless track circuits require fewer impedance bonds than any other double rail traction return track circuits. Disadvantages of jointless track circuits: Restrictions on placing impedance bonds, hence any connection for electrification purposes, in or near tuned zones as this may upset the filter properties of the tuned ...

    In November 2023, Hitachi Vantara launched the Pentaho+ Platform, comprising the original Pentaho Data Integration and Pentaho Business Analytics] software, and new Pentaho Data Catalog, and [Pentaho Data Optimiser software products. Hitachi Vantara intends to extend the Pentaho+ platform with tools for Data Quality and Data Mastering.

  5. Simcenter Amesim - Wikipedia

    en.wikipedia.org/wiki/Simcenter_Amesim

    Simcenter Amesim is a multi-domain software that supports modeling a variety of physics domains (hydraulic, pneumatic, mechanic, electrical, thermal, electromechanical). It is based on the Bond graph theory. Under the Windows platform, Simcenter Amesim works with the free Gcc compiler, which is provided with

  6. Zigzag transformer - Wikipedia

    en.wikipedia.org/wiki/Zigzag_transformer

    The transformer's impedance should not be too low for desired maximum fault current. Impedance can be added after the secondaries are summed to limit maximum fault currents (the 3I o path). [6] A combination of Y (wye or star), delta, and zigzag windings may be used to achieve a vector phase shift. For example, an electrical network may have a ...

  7. Electrical susceptance - Wikipedia

    en.wikipedia.org/wiki/Electrical_susceptance

    In the special case of entirely zero admittance or exactly zero impedance, the relations are encumbered by infinities. However, for purely-reactive impedances (which are purely-susceptive admittances), the susceptance is equal to the negative reciprocal of the reactance , except when either is zero.

  8. Characteristic impedance - Wikipedia

    en.wikipedia.org/wiki/Characteristic_impedance

    The input impedance of an infinite line is equal to the characteristic impedance since the transmitted wave is never reflected back from the end. Equivalently: The characteristic impedance of a line is that impedance which, when terminating an arbitrary length of line at its output, produces an input impedance of equal value. This is so because ...

  9. Impedance parameters - Wikipedia

    en.wikipedia.org/wiki/Impedance_parameters

    A Z-parameter matrix describes the behaviour of any linear electrical network that can be regarded as a black box with a number of ports.A port in this context is a pair of electrical terminals carrying equal and opposite currents into and out-of the network, and having a particular voltage between them.
