A shunt to measure pulse currents
, 2012 The principles of design and construction of the shunt to measure pulse currents to 1 kA with fronts pulses over 1 μsec are described. The peculiarity of the shunt is a tubular bifilar design in which internal resistive tube replaced nichrome wires ...

Materials and Corrosion, EarlyView.A novel thick‐track electrical resistance probe with five sensing tracks was developed for offshore corrosion monitoring. The probe provides reliable, real‐time corrosion‐rate measurements in natural seawater. Corrosion‐rate trends showed strong agreement with weight‐loss coupon measurements.

The effect of field resistance on speed of DC shunt motor
, 2007 The objective of the experiment in this project is to study the speed of DC shunt motor when it is supplied by voltage. The speed of the DC shunt motor is controlled by variable-field resistance.

Fracture of the Passive Film on Reinforcing Steel in Concrete Under Mechanical Loading
Materials and Corrosion, EarlyView.Bending load induces a flexural crack in reinforced concrete specimen. Above the critical load inducing crack, a macro cell corrosion current is recorded by steel coupons embedded in the concrete. The macro cell current corresponds to the rupture of the passive film. ABSTRACT This study investigates the fracture of the passive film on reinforcing steel

5D Flow MRI Reveals Respiration‐Driven Changes in Blood Flow Energetics in Congenital Heart Disease
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Hemodynamic monitoring is essential for patients with right‐sided congenital heart disease (CHD). Respiration may have an increased impact on pulmonary flow in these patients that cannot be assessed by standard tools including 4D flow MRI. This study uses 5D flow MRI to assess respiratory‐cycle variations in flow energetics in patients
