An Indirect Measurement Methodology to Identify Load Fluctuations on Axial Turbine Runner Blades
Sensors, 2020 Smooth integration of intermittent energy sources, such as solar and wind power, into the electrical grid induces new operating conditions of the hydraulic turbine by increasing the off-design operations, start/stops, and load variations.

Full surface strain measurement using shearography [PDF]
, 2001 Shearography is a full-field optical technique usually used for the determination of surface strain. Correlation of interferometric speckle patterns recorded before and after the object deformation yields fringes sensitive to displacement gradient ...

Measurement of Visual Strain in Radiologists [PDF]
Academic Radiology, 2009 The authors hypothesized that the current practice of radiology produces oculomotor fatigue that reduces diagnostic accuracy.Testing this hypothesis required an ability to measure eyestrain. This capability was developed by measuring the visual accommodation of radiologists before and after diagnostic viewing work using an autorefractor that was ...

Polarized cathodoluminescence for strain measurement [PDF]
Review of Scientific Instruments, 2019 Strain can alter the properties of semiconductor materials. The selection of a strain measurement technique is a trade-off between sensitivity, resolution, and field of view, among other factors. We introduce a new technique based on the degree of polarization of cathodoluminescence (CL), which has excellent sensitivity (10−5), an intermediate ...
