Phase aberration balancing of cataracts using holography
Experimental Eye Research, 1973Abstract Based on the evidence that cataracts degrade image resolution, primarily by light scattering, an attempt was made to see through a cataract, by optically compensating for the scattering. The technique employed is known as phase aberration balancing by use of holography.

Balancing the grid with single-phase PV-installations
2017 IEEE 26th International Symposium on Industrial Electronics (ISIE), 2017Many state of the art voltage control algorithms aim at reducing voltage rise in distribution grids caused by distributed in-feed, e.g. Photovoltaics (PV), by reactive power control strategies or active power curtailment. Due to the R/X-ratio, the effectiveness of reactive power on the voltage is generally more effective in medium voltage networks (MV)

Phase balancing for aircraft electrical distribution systems
IEEE Transactions on Aerospace and Electronic Systems, 2015The aircraft of the future will use several new concepts to improve its electrical power supply system, transforming it into a small smart distribution grid. Among these concepts, power management systems, increase in the main bus voltage, integration of high-voltage direct current grids, phase balancing, and power feeder balancing have been suggested.

Balanced optical-microwave phase detectors for optoelectronic phase-locked loops
Optics Letters, 2006A balanced optical-microwave phase detector for the extraction of low-jitter, high-power, and drift-free microwave signals from optical pulse trains is presented. The phase detection is based on electro-optic sampling with a differentially biased Sagnac loop. Because the timing information is transferred in the optical domain, the regenerated microwave

A novel method for balancing of three-phase network with a single phase load
2016 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2016When a three-phase power line connected to unbalanced loads, its terminal voltages and line currents become also unbalanced. The most unfavorable load for three phase network or stand-alone generator is a single-phase load. Present study suggests a novel method for operating single-phase load connected to three-phase network while keeping generator ...

A Balanced Phase Field Model for Active Contours
2019In this paper we present a balanced phase field model that eliminates the often undesired curvature-dependent shrinking of the zero level set, while maintaining the smooth interface necessary to calculate fundamental quantities such as the normal vector or the curvature of the represented contour.

Most of the current domestic installations are single phase, with contracted power equal to or less than 15 kW and with a potential difference of 230 V. When consumption is expected to be higher you choose to use three different alternating currents with a difference voltage of 400 V between them, which are called phases.
