Power transformer geometry monitoring of active parts by SFRA method [PDF]

Zbornik Radova: Elektrotehnički Institut "Nikola Tesla", 2014
During regular operation, power transformer windings are continuously exposed to electromechanical stresses and vibrations. Surges during lightning or short circuits may cause the weakening of the mechanical structure and the mechanical reinforcing parts

Tri-axial Octupole Deformations and Shell Structure [PDF]

, 1999
Manifestations of pronounced shell effects are discovered when adding nonaxial octupole deformations to a harmonic oscillator model. The degeneracies of the quantum spectra are in a good agreement with the corresponding main periodic orbits and winding ...

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...
