In-situ digital image correlation and thermal monitoring in directed energy deposition additive manufacturing

Optics Express, 2021
As in welding, directed energy deposition (DED) additive manufacturing (AM) generates complex residual stresses and distortions commensurate with the complexity of the scan pattern used for deposition. To date, measuring DED distortions on complex geometries has only been achieved post process, discarding the complex thermomechanical history that leads

Digital thermal monitoring (DTM) of vascular reactivity closely correlates with doppler flow velocity [PDF]

2009 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2009
The noninvasive measurement of peripheral vascular reactivity, as an indicator of vascular function, provides a valuable tool for cardiovascular screening of at-risk populations. Practical and economical considerations demand that such a test be low-cost and simple to use.

Automatic detection of regions in spinach canopies responding to soil moisture deficit using combined visible and thermal imagery [PDF]

, 2014
Thermal imaging has been used in the past for remote detection of regions of canopy showing symptoms of stress, including water deficit stress. Stress indices derived from thermal images have been used as an indicator of canopy water status, but these ...
