Research on Co-phase Power Supply Test System

Energy and Power Engineering, 2013
Co-phase power supply system can solve the problems of power quality of heavy unbalanced three phase, large harmonics and reactive power and cancel neutral section in electric railway power supply system. In order to do further research, a co-phase power supply test system is proposed.

Antarctic temperature and CO₂: near-synchrony yet variable phasing during the last deglaciation [PDF]

Climate of the Past, 2019
The last deglaciation, which occurred from 18 000 to 11 000 years ago, is the most recent large natural climatic variation of global extent.

Unintended consequences of the potential phase-out of gamma irradiation [version 1; referees: 2 approved]

F1000Research, 2018
The radioisotope cobalt-60 (Co-60) is important for commercial, medical, and agricultural applications. Its widespread use has meant that Co-60 can be found in less secured facilities, leading to the fear that unauthorized persons could obtain and use it

Familial co-segregation and the emerging role of long-read sequencing to re-classify variants of uncertain significance in inherited retinal diseases

npj Genomic Medicine, 2023
Phasing genetic variants is essential in determining those that are potentially disease-causing. In autosomal recessive inherited retinal diseases (IRDs), reclassification of variants of uncertain significance (VUS) can provide a genetic diagnosis in ...

Challenges in charge preparation and combustion in homogeneous charge compression ignition engines with biodiesel: A review

Energy Reports, 2019
Homogeneous charge compression ignition (HCCI) engines have high efficiency and lower NOx-soot emissions than diesel and gasoline engines. However, these engines suffer from high HC, CO and unregulated emissions and combustion phasing control.

Effective a posteriori co-phasing of interferometric fringe data [PDF]

SPIE Proceedings, 2016
We have recently shown that a posteriori co-phasing of multi-spectral interferograms was possible.1 In this contribution, we extend our approach so that it can be applied to actual data as provided by Amber 2 or Matisse instruments. The main advantage of the proposed post-processing technique is that it requires no modifications of the instruments and ...
