Single Phasing Effects on the Behavior of Three-Phase Induction Motor
Tikrit Journal of Engineering Sciences, 2023 The output of three-phase induction motors (3IM) is adversely affected by voltage imbalance. This work analyzes and estimates the output of a 3PIM operating on a balanced supply while contrasting it with a "single phasing" case.

Power control strategies during voltage sags according to Spanish grid code [PDF]
, 2018 In order to connect any power converters into the grid there are some grid requirements to insure the safe operation of the grid. So, the control of the converters especially during abnormal condition e.g. during voltage sags is

Effects of Negative Sequence Voltage Subharmonics on Cage Induction Motors
Energies, 2022 In some power systems, voltage waveforms contain, apart from harmonics, interharmonics and subharmonics that are components of frequency less than or not an integer multiple of the fundamental frequency.

The nuanced negative: Meanings of a negative diagnostic result in clinical exome sequencing [PDF]
Sociology of Health & Illness, 2016 AbstractGenomic sequencing technology is moving rapidly from the research setting into clinical medicine but significant technological and interpretive challenges remain. Exome sequencing (ES) in its recent clinical application provides a genetic diagnosis in about 25 per cent of cases (Berg 2014).

A Comprehensive VSM Control Strategy Designed for Unbalanced Grids
Energies, 2019 A virtual synchronous machine (VSM) is a converter which, compared to other types of converters, has more friendly interactions with the power grid because it is able to simulate the external characteristics of a synchronous machine, which can provide ...
