theoretical investigations on the characteristics of the nuclear quadrupole resonance and the influence of the magnetic effect on it have been carried out. the magnetic dipole effect on the quadrupole resonance for the two spins i and i with different values oft) and e has been studied. the energy levels and their transition probabilities are presented with their corresponding spectra. the firs...

Stray magnetic field is one of the main issues in design of transformers, since it causes non-ideal behavior of transformers. One of the techniques is usually adopted to mitigate the unwanted stray magnetic field is the use of auxiliary windings creating a magnetic field opposite to the incident one giving rise to the reduction of the total magnetic fields. This paper presents a new mathematica...

A novel optical fiber current sensor for low-current measurements is proposed and tested. By winding a commonly used low-birefringence single-mode optical fiber in a special geometry, one can circumvent the bend-induced birefringence problem. Smaller sensors can now be built with a sensitivity that linearly increases with the number of fiber windings.

BACKGROUND Postural asymmetries with seating problems are common in adults with cerebral palsy. AIMS To analyse the prevalence of asymmetrical limited hip flexion (<90°) in adults with CP, and to evaluate the association between asymmetrical limited hip flexion and postural asymmetries in the sitting position. METHODS AND PROCEDURES Cross-sectional data of 714 adults with CP, 16-73 years, G...
