Phase-Angle Control of System Interconnections

Transactions of the American Institute of Electrical Engineers, 1939
This paper describes an application of a new method of automatic control between two interconnected power systems, whereby greater utilization of the interconnection capacity is secured. As the stable limit of the interchange between systems is affected by variations in the magnitude and location of intermediate loads on the respective systems, direct ...

The Weyl Quantization of Phase Angle

Journal of Modern Optics, 1992
We suggest a candidate for a non-canonical Hermitian operator corresponding to phase angle, based on the Weyl correspondence rule. The matrix elements of this operator, for harmonic oscillator number states, coincide, in the correspondence limit, with those of a phase operator proposed by Barnett and Pegg, when the dimension of their defining space ...

Effect of normalization and phase angle calculations on continuous relative phase

Journal of Biomechanics, 2002
The purpose of this investigation was to determine if phase plot normalization and phase angle definitions would have an affect on continuous relative phase calculations. A subject ran on a treadmill while sagittal plane kinematic data were collected with a high-speed (180 Hz) camera.

Progress in phase angle thermography

Review of Scientific Instruments, 2003
Phase angle thermography is basically spatially multiplexed photothermal radiometry. It provides images for remote detection and imaging of damage. For energy deposition one can use external heat sources (e.g., light or convective heating) or internal heat generation (e.g., electric current, microwaves, eddy current, or elastic wave).

Phase Angles of Sound as a Biometric Feature

2012
The paper is a proposal of concept of highlighting the sound sources based on the phase shifts of successive harmonics in a single function course extracted from a articulation of single sound which frequency is stable in short-term. The function describing the single period of sound is expanded for the purpose of determining the harmonic series from −∞

MLD's and the Phase Angle, Alpha

The Journal of the Acoustical Society of America, 1968
This Letter describes two experiments designed to discover the effect of the phase angle, α (the angle between a narrow-band masker and a tonal signal), on binaural detection, and offers an explanation of why they failed to reveal any effect.

Remote measurement of phase angle

Proceedings of the Institution of Electrical Engineers, 1972
A system is described for the measurement of the phase angle between two voltages separated from each other, and from the point where the results are to be displayed, by a distance of several miles. A correction for the transmission delay of the measurement signals is automatically made, and an accurate knowledge of the transmission-path ...

Quantum Phase Angles and su(∞)

Journal of Modern Optics, 1991
Abstract The polar decomposition of the su(2) algebra leads to unitary phase operators which do not close to an algebra with the number operator. It is shown that phase and number operators can be embedded into a larger su(2j + 1) algebra with trigonometric structure constants.
