Estimation of Transformers Health Index Based on the Markov Chain

Energies, 2017
This paper presents a study on the application of the Markov Model (MM) to determine the transformer population states based on Health Index (HI). In total, 3195 oil samples from 373 transformers ranging in age from 1 to 25 years were analyzed.

Slice‐Wise Quality Assessment of High b Value Breast DWI via Deep Learning‐Based Artifact Detection

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Diffusion‐weighted imaging (DWI) can support lesion detection and characterization in breast MRI. Therefore, DWI is increasingly being incorporated into breast MRI protocols to address some of the shortcomings of routine clinical breast MRI.

Clinical and self‐reported measurements to be included in the core elements of the World Dental Federation's theoretical framework of oral health

International Dental Journal, EarlyView., 2020
Introduction Oral health is part of general health, and oral diseases share risk factors with several non‐communicable diseases. The World Dental Federation (FDI) has published a theoretical framework illustrating the complex interactions between the core elements of oral health (CEOHs): driving determinants, moderating factors, and general health and ...

Assessment of the Exposure of Australia to Tropical Cyclones Through a Climatological Model for Cyclone Weather Extent

International Journal of Climatology, EarlyView.
Australia has different levels of exposure to tropical cyclones. Using historical records, this study investigates the spatial variability of tropical cyclone formation across the Southeast Indian–South Pacific basin, quantifies the exposure of different parts of Australia to tropical cyclone weather events, and examines decadal variability in cyclone ...
