Dynamic caliper matching [PDF]
Central European Journal of Economic Modelling and Econometrics, 2011 Matched sampling is a methodology used to estimate treatment effects. A caliper mechanism is used to achieve better similarity among matched pairs. We investigate finite sample properties of matching with calipers and propose a slight modification to the existing mechanism.

Ultrasonics, 1973
Abstract A new electronic caliper of unique design is described. The determination of the timing intervals is accomplished by digital means providing an accuracy dependent only upon a single crystal-controlled oscillator. Means has also been provided for varying the display to match different assumed sonic velocities without impairment of accuracy ...

Abstract Caliper logging is a practice of measuring the variations in the diameter ofthe open hole in a well. This information is useful for many purposes, amongwhich are: Determining the volumetric capacity of the portion of open hole tobe cemented; the amount of gravel to be used for gravel-packing a well; thesize
