  2. Occupancy–abundance relationship - Wikipedia

    en.wikipedia.org/wiki/Occupancy–abundance...

    For example, in describing O–A relationships for common British birds, Quinn et al. [7] found that the occupancy at the finest resolution (10 x 10 km squares) best explained abundance patterns. In a similar manner, Zuckerberg et al. [ 8 ] used Breeding Bird Atlas data measured on cells 5 × 5 km to describe breeding bird occupancy in New York ...

  3. Cut-elimination theorem - Wikipedia

    en.wikipedia.org/wiki/Cut-elimination_theorem

    The cut-elimination theorem (or Gentzen's Hauptsatz) is the central result establishing the significance of the sequent calculus.It was originally proved by Gerhard Gentzen in part I of his landmark 1935 paper "Investigations in Logical Deduction" [1] for the systems LJ and LK formalising intuitionistic and classical logic respectively.

  4. Concentric zone model - Wikipedia

    en.wikipedia.org/wiki/Concentric_zone_model

    Based on human ecology theory done by Burgess and applied on Chicago, it was the first to give the explanation of distribution of social groups within urban areas.This concentric ring model depicts urban land usage in concentric rings: the Central Business District (or CBD) was in the middle of the model, and the city is expanded in rings with different land uses.

  5. Borchert's Epochs - Wikipedia

    en.wikipedia.org/wiki/Borchert's_Epochs

    Borchert's epochs refer to five distinct periods in the history of American urbanization and are also known as Borchert's model of urban evolution. Each epoch is characterized by the impact of a particular transport technology on the creation and differential rates of growth of American cities.

  6. Post-occupancy evaluation - Wikipedia

    en.wikipedia.org/wiki/Post-occupancy_evaluation

    Other commonly used quantitative measures include space metrics, for example occupational density, space utilization and tenant efficiency ratio. Cost, either expressed as the cost of the project per square meter or the total cost of occupancy, is considered a key metric in building evaluation and may be compared with the occupant feedback to ...

  7. Monotonicity of entailment - Wikipedia

    en.wikipedia.org/wiki/Monotonicity_of_entailment

    The weakening rule may be expressed as a natural deduction sequent: Γ ⊢ C Γ , A ⊢ C {\displaystyle {\frac {\Gamma \vdash C}{\Gamma ,A\vdash C}}} This can be read as saying that if, on the basis of a set of assumptions Γ {\displaystyle \Gamma } , one can prove C, then by adding an assumption A, one can still prove C.

  8. Multiple nuclei model - Wikipedia

    en.wikipedia.org/wiki/Multiple_nuclei_model

    The model describes the layout of a city, based on Chicago. It says that even though a city may have begun with a central business district, or CBD, other smaller CBDs develop on the outskirts of the city near the more valuable housing areas to allow shorter commutes from the outskirts of the city.

  9. Dispersed settlement - Wikipedia

    en.wikipedia.org/wiki/Dispersed_settlement

    Dispersed settlement or Streusiedlung in Brülisau, Appenzell Innerrhoden, Switzerland. A dispersed settlement, also known as a scattered settlement, is one of the main types of settlement patterns used by landscape historians to classify rural settlements found in England and other parts of the world.
