  2. Input–output model - Wikipedia

    en.wikipedia.org/wiki/Inputoutput_model

    Inputoutput planning was never adopted because the material balance system had become entrenched in the Soviet economy, and inputoutput planning was shunned for ideological reasons. As a result, the benefits of consistent and detailed planning through inputoutput analysis were never realized in the Soviet-type economies .

  3. Social geography - Wikipedia

    en.wikipedia.org/wiki/Social_geography

    Social geography is the branch of human geography that is interested in the relationships between society and space, and is most closely related to social theory in general and sociology in particular, dealing with the relation of social phenomena and its spatial components.

  4. Geophysical survey - Wikipedia

    en.wikipedia.org/wiki/Geophysical_survey

    Geophysical survey is the systematic collection of geophysical data for spatial studies. Detection and analysis of the geophysical signals forms the core of Geophysical signal processing. The magnetic and gravitational fields emanating from the Earth's interior hold essential information concerning seismic activities and the internal structure.

  5. Computational geophysics - Wikipedia

    en.wikipedia.org/wiki/Computational_geophysics

    Computational geophysics is the field of study that uses any type of numerical computations to generate and analyze models of complex geophysical systems. It can be considered an extension, or sub-field, of both computational physics and geophysics.

  6. Open system (systems theory) - Wikipedia

    en.wikipedia.org/wiki/Open_system_(systems_theory)

    Open systems have input and output flows, representing exchanges of matter, energy or information with its surroundings. An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the ...

  7. Sociological theory - Wikipedia

    en.wikipedia.org/wiki/Sociological_theory

    In terms of sociology, historical sociology is often better positioned to analyze social life as diachronic, while survey research takes a snapshot of social life and is thus better equipped to understand social life as synchronic. Some argue that the synchrony of social structure is a methodological perspective rather than an ontological claim ...

  8. Geophysics - Wikipedia

    en.wikipedia.org/wiki/Geophysics

    Geophysics is a highly interdisciplinary subject, and geophysicists contribute to every area of the Earth sciences, while some geophysicists conduct research in the planetary sciences. To provide a more clear idea on what constitutes geophysics, this section describes phenomena that are studied in physics and how they relate to the Earth and ...

  9. Magnetotellurics - Wikipedia

    en.wikipedia.org/wiki/Magnetotellurics

    The resulting output of the processing program is used as the input for subsequent interpretation. Processing may include the use of remote reference data or local data only. Processed MT data is modelled using various techniques to create a subsurface resistivity map, with lower frequencies generally corresponding to greater depth below ground.
