A circular loop time constant standard for the determination of phase angle errors of current shunts
2018 First International Colloquium on Smart Grid Metrology (SmaGriMet), 2018The paper describes a simple time constant standard, developed for the phase angle measurement of the precision current shunts. Its design is based on a single circular loop, placed in an air thermostat.

Fourth generation switching power supply for circular induction accelerators.
Review of Scientific Instruments, 2023A switching power supply (SPS) was applied as the high-frequency bipolar high-voltage pulse source required to accelerate charged particles in the induction synchrotron, which was a novel synchrotron proposed at the High Energy Accelerator Research ...

Transcatheter resolution of a post-surgical "Iatrogenic" circular shunt in a child.
Cardiology in the YoungCircular shunt is a very rare, albeit critical, condition. We present a case of a post-surgical circular shunt that resulted after correction of an anomalous total pulmonary venous connection to the coronary sinus with a persistent left superior vena ...

MAGNETIC CIRCULAR SHUNTS FOR STRAY FLUX IN POWER TRANSFORMERS
2021Energetski transformator jedan je od ključnih elemenata elektroenergetskog sustava te o njegovoj pouzdanosti i učinkovitosti ovise pouzdanost i učinkovitost čitavog sustava. Stoga je pri projektiranju transformatora bitno minimizirati vjerojatnost kvara, ali i gubitke.

Control of circular plate vibrations via piezoelectric actuators shunted with a capacitive circuit
Thin-Walled Structures, 2001Abstract The purpose of this research is to analyse capacitively shunting distributed piezoelectric elements perfectly glued to the vibrating annular plate excited by harmonic displacement of the inner plate edge. The piezoelement is described by constitutive equations relating stresses and electric displacements with strains and electric field.

This work presents an investigation on vibration transmission in a circular thin plate consisting of metal rings and piezoelectric rings arrayed periodically. Each piezoelectric ring is linked to an independent resistive–inductive (RL) resonant shunting circuit.

[Circular shunting of blood: a complication of neonatal Ebstein anomaly].
Archives de pediatrie : organe officiel de la Societe francaise de pediatrie, 2011We report a severe neonatal presentation of Ebstein anomaly with homodynamic aggravation at birth attributed to patent ductus arteriosus and circular shunt. Prenatal diagnosis of Ebstein anomaly of the tricuspid valve with functional pulmonary atresia was made at 37 weeks gestation by fetal two- and three-dimensional echocardiography.

Complete Right Heart Flow Reversal
Journal of Ultrasound in Medicine, 2009Although the pathophysiologic mechanism of twin-twin transfusion syndrome (TTTS) remains incompletely understood, the process appears to involve abnormal vascular communications within the placenta, leading to characteristic hemodynamic changes in the recipient fetus.

Undesired vibration may occur in lightweight structures due to excitation and low damping. For the purpose of lateral vibration attenuation in beam structures, piezoelectric transducers shunted to negative capacitances can be an appropriate measure.
