An Online Condition Assessment of Box Substation in Wind Farm Based on Hypothesis Testing

IEEE Access, 2020
With the rapid development of wind generation, the box substation is widely applied in the wind farm. However the box substation is more prone to break down than the conventional power transformer, due to the uncertainty of wind power.

Calculation of Hot Spot Temperature of Transformer Bushing Considering Current Fluctuation

IEEE Access, 2019
The transformer bushing hot spot temperature (HST) seriously affects its performance and design. In this paper, a novel method for calculating the hot spot temperature of bushing is proposed, in which the principle of constant joule heat is adopted to ...

SK-FRCNN: A Fault Detection Method for Hot Spots on Photovoltaic Panels

IEEE Access, 2023
Photovoltaic power generation is clean and environmentally friendly, and has been widely used. Hot spots on photovoltaic panels, caused by shading and leading to heating, reduce the efficiency of photovoltaic power generation and even damage the panels ...

Identifying Malaria Hot Spots [PDF]

The Journal of Infectious Diseases, 2017
Where effective control measures (drugs, insecticide treated nets, and in some areas insecticides) are being deployed, malaria is coming down. The map is changing. Thirty years ago most of sub-Saharan Africa had high malaria transmission during the rainy season or throughout the year, but in increasing areas transmission has fallen markedly.

Voltage-Based Hot-Spot Detection Method for Photovoltaic String Using a Projector

Energies, 2017
This paper proposes a voltage-based hot-spot detection method for photovoltaic (PV) string using the projector. Hot-spots form in solar cells at defects causing a high carrier recombination rate, it appears as a high reverse leakage current of p-n ...

Hot spot localization in the field of view of the Kirkpatrick–Baez microscope

AIP Advances
The Kirkpatrick–Baez (KB) microscope is an effective instrument for x-ray imaging of hot spot. However, the non-uniform distribution of response efficiency in the field of view is a drawback of the KB microscope.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
