Generalized two axes model of a squirrel-cage induction motor for rotor fault diagnosis [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2008
A generalized two axes model of a squirrel-cage induction motor is developed This model is based on a winding function approach and the coupled magnetic circuit theory and takes into account the stator and the rotor asymmetries due to faults.

The non-negligible effect of magnetic holes on the magnitude-of-B magnetic power spectral density of the fast Alfvenic coronal-hole-origin solar wind at 1 AU

open access: yesFrontiers in Astronomy and Space Sciences
To estimate the effects of magnetic holes on the magnitude of B magnetic power spectral density, a 2-day interval of fast coronal-hole-origin plasma at 1 AU is examined. The magnetic holes are identified and removed from the magnetic time series, and the

A Subject-Specific Attention Index Based on the Weighted Spectral Power

open access: yesIEEE Transactions on Neural Systems and Rehabilitation Engineering
As an essential cognitive function, attention has been widely studied and various indices based on EEG have been proposed for its convenience and easy availability for real-time attention monitoring.

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Monitoring the Depth of Anesthesia Using Discrete Wavelet Transform and Power Spectral Density

open access: yes, 2009
This method combines wavelet techniques and power spectral density to monitor the depth of anesthesia (DOA) based on simplified EEG signals. After decomposing electroencephalogram (EEG) signals, the power spectral density is chosen as a feature function ...

Emerging experimental and computational methods for studying redox‐regulated structural transitions

open access: yesFEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Numerical Optimization and Cyber-Physical- Social Computing for Vibrations of the Elliptical Treadmill Based on GSO-BPNN Model

open access: yesIEEE Access, 2018
The finite element method was used to compute the vibration characteristics of the elliptical treadmill, and the computational results were then compared with those of the experimental test to verify its correctness.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

open access: yesFEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...
