Development of a digital phase angle meter

2016 International Conference on Control, Instrumentation, Communication and Computational Technologies (ICCICCT), 2016
This paper presents a simple yet effective method to determine the phase angle difference across any load connected to the supply. The proposed idea works on conditioning of the current and voltage signals in and across the load line and displays the phase difference through a Digital Panel Meter. It can indicate leading or lagging phase through a lead-

Berry's phase and Hannay's angle for spin systems

Physical Review D, 1993
The classical limit of a quantum spin system is considered. Berry's relation between Hannay's angle and the semiclassical limit for Berry's phase is proven to be valid in this case.

Association of Bioelectrical Impedance Analysis–Derived Phase Angle and Sarcopenia in Older Adults

Nutrition in clinical practice, 2017
Background: Sarcopenia is an important problem for older adults, leading to morbidity and mortality; therefore, early detection with a precise method is essential.

Ultralinear small-angle phase modulator

Proceedings of the 45th Annual Symposium on Frequency Control 1991, 2002
A DC electric field applied to a quartz plate resonator causes changes in the elastic constants which can lead to a change in the frequency of the resonator. This effect, known as the polarizing effect, has been shown to be extremely linear. A method for measuring the polarizing effect in high-Q SC-cut 5-MHz quartz resonators for small AC electric ...
