  2. Vertex distance - Wikipedia

    en.wikipedia.org/wiki/Vertex_distance

    Vertex distance. Vertex distance is the distance between the back surface of a corrective lens, i.e. glasses (spectacles) or contact lenses, and the front of the cornea. Increasing or decreasing the vertex distance changes the optical properties of the system, by moving the focal point forward or backward, effectively changing the power of the ...

  3. Construction estimating software - Wikipedia

    en.wikipedia.org/wiki/Construction_estimating...

    Many construction cost estimators continue to rely primarily upon manual methods, hard copy documents, and/or electronic spreadsheets such as Microsoft Excel. While spreadsheets are relatively easy to master and provide a means to create and report a construction cost estimate and or cost models, their benefit comes largely from their ability ...

  4. COBie - Wikipedia

    en.wikipedia.org/wiki/COBie

    COBie has been incorporated into software for planning, design, construction, commissioning, operations, maintenance, and asset management. COBie may take several approved formats include spreadsheet, STEP-Part 21 (also called IFC file format), and ifcXML. The current COBie test data of record was developed by an international team of designers ...

    en.wikipedia.org/wiki/NodeXL

    NodeXL is a network analysis and visualization software package for Microsoft Excel 2007/2010/2013/2016. [2] [3] The package is similar to other network visualization tools such as Pajek, UCINet, and Gephi. [4] It is widely applied in ring, mapping of vertex and edge, and customizable visual attributes and tags.

  6. Simplex - Wikipedia

    en.wikipedia.org/wiki/Simplex

    as can be seen by multiplying the previous formula by x n+1, to get the volume under the n-simplex as a function of its vertex distance x from the origin, differentiating with respect to x, at = / (where the n-simplex side length is 1), and normalizing by the length / + of the increment, (/ (+), …, / (+)), along the normal vector.

  7. Vincenty's formulae - Wikipedia

    An example of an incorrect result is provided by the NGS online utility, which returns a distance that is about 5 km too long. Vincenty suggested a method of accelerating the convergence in such cases (Rapp, 1993).

  8. Hudson Formula - Wikipedia

    en.wikipedia.org/wiki/Hudson_Formula

    The Hudson Formula derives from Hudson's Building and Engineering Contracts and is used for the assessment of delay damages in construction claims.. The formula is: (Head Office overheads + profit percentage) ÷ 100 x contract sum ÷ period in weeks x delay in weeks

  9. Deflection (engineering) - Wikipedia

    en.wikipedia.org/wiki/Deflection_(engineering)

    It may be quantified in terms of an angle (angular displacement) or a distance (linear displacement). A longitudinal deformation (in the direction of the axis) is called elongation . The deflection distance of a member under a load can be calculated by integrating the function that mathematically describes the slope of the deflected shape of ...
