Spontaneously broken technicolor and the dynamics of virtual vector technimesons
Physical Review D, 1993 We propose spontaneously breaking technicolor, thus liberating techniquarks and suppressing large resonance contributions to the electroweak $S$ parameter. The dynamics is modeled by a fermion bubble approximation to a single massive techni--gluon exchange potential. This contains a Nambu--Jona-Lasinio model with additional interactions.

Fault Tolerance in Direct Torque Control with Virtual Voltage Vectors
Revista Iberoamericana de Automática e Informática Industrial RIAI, 2019 Reliability is considered a fundamental requirement of some variable-speed electric drives. Therefore, multiphase systems, which introduce a higher fault tolerance than conventional three-phase ones, turn out to be an interesting alternative for these ...
