Screening current effects in Josephson junction arrays [PDF]

open access: yes, 1995
The purpose of this work is to compare the dynamics of arrays of Josephson junctions in presence of magnetic field in two different frameworks: the so called XY frustrated model with no self inductance and an approach that takes into account the ...

Designing Ultrahigh Frequency Motor Rotor Position Search Coils for Electric Propulsion in Drones

open access: yesDrones, 2023
As the core of electric propulsion in drones, the motor has higher requirements for its reliability and fault tolerance. Accurate acquisition of rotor position information is a prerequisite for a motor-driven drone’s system to operate stably. Traditional

Influence of machine topology and cross-coupling magnetic saturation on rotor position estimation accuracy in extended back-EMF based sensorless PM brushless AC drives [PDF]

open access: yes, 2007
The influence of the machine topology and dq-axis cross-coupling on the rotor position estimation error in an extended back-EMF based sensorless brushless AC drive is investigated by both finite element analysis and experimentally on four brushless AC ...

Misoprostol and attempted self-induction of abortion [PDF]

open access: yesJournal of the Royal Society of Medicine, 1998
Sporadic reports have documented the use in countries such as Brazil and Mozambique of misoprostol to self-induce pregnancy termination (PT). This paper presents the case of a young woman from Mozambique who presented to a UK surgery requesting PT .

Mapping Methodology for Self and Mutual Inductance Profiles in IPT Systems

open access: yesEnergies, 2022
Magnetic couplers (MC) are the key element that enable the power transfer over large air gaps in inductive power transfer (IPT) systems. Numerous designs with different coil and core arrangements have been proposed in the literature.

Kinetic modelling of a self-sustained TEA CO2 laser [PDF]

open access: yes, 1980
Recently new experimental values for the electron-ion recombination and the avalanche coefficients have been obtained. The results have been used to predict the time behaviour of the laser current and voltage.
