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.
The strong overconfidence in the accuracy of the effort estimates is illustrated by the finding that, on average, if a software professional is 90% confident or "almost sure" to include the actual effort in a minimum-maximum interval, the observed frequency of including the actual effort is only 60-70%.

Trend analysis can be also used for word usage, how words change in the frequency of use in time (diachronic analysis), in order to find neologisms or archaisms. It relates to diachronic linguistics , a field of linguistics which examines how languages change over time.
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 ...
