Base curve radius (BCR) or simply base curve (BC) is the measure of an important parameter of a lens in optometry. On a spectacle lens, it is the flatter curvature of the front surface. On a contact lens it is the curvature of the back surface and is sometimes referred to as the back central optic radius (BCOR). Typical values for a contact ...
Stresses in a contact area loaded simultaneously with a normal and a tangential force. Stresses were made visible using photoelasticity.. Contact mechanics is the study of the deformation of solids that touch each other at one or more points.
An online calculator is available on www.tribonet.org that allows calculating Stribeck curve for line [16] and point [17] contacts. These tools are based on the load-sharing concept. Also molecular simulation based on classical force fields can be used for predicting the Stribeck curve. [18] Thereby, underlying molecular mechanisms can be ...
Data analyses in Origin include statistics, signal processing, curve fitting and peak analysis. Origin's curve fitting is performed by a nonlinear least squares fitter which is based on the Levenberg–Marquardt algorithm. Origin imports data files in various formats such as ASCII text, Excel, NI TDM, DIADem, NetCDF, SPC, etc.
The Congressional Black Caucus will have 62 members in the 119th Congress, contributing to a record 67 Black representatives.
Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term spreadsheet may also refer to one such electronic document. [5] [6] [7] Spreadsheet users can adjust any stored value and observe the effects on calculated values.
From January 2008 to December 2012, if you bought shares in companies when Thomas H. Kean joined the board, and sold them when he left, you would have a -67.6 percent return on your investment, compared to a -2.8 percent return from the S&P 500.
Within Excel, the goal seek function can be used to set column 15 to 0 by changing the depth estimate in column 2 instead of iterating manually.
