Gauge Miura and Bäcklund transformations for generalized An-KdV hierarchies
(2021-10-29)
The construction of Miura and Bäcklund transformations for An mKdV and KdV hierarchies are presented in terms of gauge transformations acting upon the zero curvature representation. As in thewell knownsl(2) case, we derive ...
A Resonant Tertiary Winding-Based Novel Air-Core Transformer Concept
(Ieee-inst Electrical Electronics Engineers IncPiscatawayEUA, 2012)
Electronic compensation of inductive voltage dividers and standard voltage transformers
(IEEE, 1999)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
Representation of transmission lines in modal domain using analytical transformation matrices
(2011-05-31)
The phases of a transmission line are tightly coupled due to mutual impedances and admittances of the line. One way to accomplish the calculations of currents and voltages in multi-phase lines consists in representing them ...
An electronic device for increasing the accuracy of high-voltage measuring transformers
(IEEE, 2000)
A new electronic system to assist high-voltage measuring transformers is proposed. This system compensates the voltage drops in the series impedances, which are the main cause of error in this type of transformer. An ...
Genetic transformation of astaxanthin mutants of Phaffia rhodozyma
(1998)
Stable red astaxanthin-producing transformants were obtained after genetic transformation of two Phaffia rhodozyma mutants. A yellow mutant, accumulating β-carotene, and an albino mutant, accumulating phytoene, from P. ...
