Digital correlation method for power measurement

Speed Measurement Method for Digital Control System

In the paper a modified digital speed measurement method is proposed. The method has a good static accuracy, like well known other measurement procedures, but its advantage consists in a constant sampling period. The method is implemented on single chip microcontroller. Experimental results proved good properties of the proposed concept.

A three-frame digital image correlation (DIC) method for the measurement of small displacements and strains

Digital image correlation (DIC) has become a well-established approach for the calculation of full-field displacement and strains within the field of experimental mechanics. Since their introduction, DIC methods have been relying on only two images to measure the displacements and strains that materials undergo under load. It can be foreseen that the use of additional image information for the ...

Evaluation of the digital image correlation method for the measurement of vibration mode shapes

Accuracy of an Intraoral Digital System for File Length Measurement

Introdouction: Canal length measurement is essential for proper endodontic treatment. Any error or miscalculation in working length determination, particularly in curved canals, can result in complications during or after root canal therapy. Digital radiography has enabled accurate measurement of curved canal length. In this study, we evaluated the accuracy of calibration of a complementary m...

Processing Digital Image for Measurement of Crack Dimensions in Concrete

The elements of the concrete structure are most frequently affected by cracking. Crack detection is essential to ensure safety and performance during its service life. Cracks do not have a regular shape, in order to achieve the exact dimensions of the crack; the general mathematical formulae are by no means applicable. The authors have proposed a new method which aims to measure the crack dimen...
