Flow rate measurement in aggressive conductive fluids

open access: yesEPJ Web of Conferences, 2014
Two non-contact experimental methods of flow rate measurements for aggressive conductive liquids are described. The techniques are based on electromagnetic forces and Faraday’s law: Lorentz force is induced inside moving conductive liquid under influence

A Study on an Anticyclonic-Cyclonic Eddy Pair Off Fraser Island, Australia

open access: yesFrontiers in Marine Science, 2020
This research examines a cyclonic-anticyclonic eddy (AE) pair off Fraser Island next to the eastern Australian coast in 2009 using the Bluelink Reanalysis data, where the local eddies are poorly understood. This eddy pair formed in July and dissipated in

Effect of optimal torque control on rotor loss of fault-tolerant permanent-magnet brushless machines [PDF]

open access: yes, 2002
A faulted phase in a fault-tolerant permanent-magnet brushless machine can result in significant torque ripple. However, this can be minimized by using an appropriate optimal torque control strategy.

A comparative study of using spindle motor power and eddy current for the detection of tool conditions in milling processes [PDF]

open access: yes, 2015
This paper investigates the use of the power of the driving motor of a CNC spindle in comparison to two perpendicular eddy current sensors for the detection of tool wear in milling processes. Monitoring the power through the current profile is a low cost

Feasibility of Imaging Tissue Electrical Conductivity by Switching Field Gradients with MRI. [PDF]

open access: yes, 2015
Tissue conductivity is a biophysical marker of tissue structure and physiology. Present methods of measuring tissue conductivity are limited. Electrical impedance tomography, and magnetic resonance electrical impedance tomography rely on passing external

The response of Southern Ocean eddies to increased midlatitude westerlies: a non-eddy resolving model study [PDF]

open access: yes, 2011
The midlatitude westerlies of the southern hemisphere have intensified since the 1970s. Non-eddy resolving general circulation models respond to such wind intensification with steeper isopycnals, a faster Antarctic Circumpolar Current (ACC), and a ...
