Size Measurement of Fine Sediments By Electrical Resistance
… fine particles of sediments and the change in resistance to the flow of electricity through a fluid containing the sediments. It was assumed that the sediments would behave according to Stokes’ Law regarding the velocities of their settling, and the pipette method of analysis was used to …

Signal and image processing for electrical resistance tomography
Electrical Resistance Tomography (ERT) is in essence an imaging technique.In ERT current is injected into and removed from a vessel via paired electrodes. The resulting voltage measurements are captured between the remaining electrode pairs. The principle behind ERT is to map these boundary …

Variation of electrical resistance in superelastic NiTi for sensor applications
… deformation. The relationship between strain and resistance is measured. The study shows that various aspects of the strain-resistance response, including non-linear hysteretic behavior and temperature dependence of electrical resistivity, pose challenges to sensor design. Though the accuracy of …

Electrical Resistance Studies of Hydrogen Diffusion and of Hydride Precipitation in Niobium
Diffusion of hydrogen in niobium was studied by using thermotransport to establish a concentration gradient in a periodic width modulated sample. A sensitive Kelvin double bridge allowed the kinetics of return to uniform concentration to be monitored. In undeformed Nb, the Arhennius plot exhibited …
