An extensive critique on expert system control in solar photovoltaic dominated microgrids
IET Renewable Power Generation, EarlyView., 2023 Solar and wind power have recently become a potential option in power systems and act significantly to meet load penetration demands. The present growth of such renewable energy sources has shown an exponential increase. The high penetration of such systems helps a grid effectively meet its load in an irregular demand but also creates some disturbances

Eddy Current Model of Ball Lightning [PDF]
arXiv, 2011 Eddy Current Model of Ball Lightning Calculations show that high-energy ball lightning may consist of a ball of plasma containing a large circular electric current arising as an eddy current generated by lightning. Synthetic ball lightning might serve as a method of plasma confinement for purposes of nuclear fusion.

Log-Gaussian Cox Process Modeling of Large Spatial Lightning Data using Spectral and Laplace Approximations [PDF]
arXiv, 2021 Lightning is a destructive and highly visible product of severe storms, yet there is still much to be learned about the conditions under which lightning is most likely to occur. The GOES-16 and GOES-17 satellites, launched in 2016 and 2018 by NOAA and NASA, collect a wealth of data regarding individual lightning strike occurrence and potentially ...

Archaeological Prospection, EarlyView.ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.

A novel approach to touch voltage risk assessment for gas pipelines in shared transmission corridors
IET Science, Measurement &Technology, Volume 17, Issue 1, Page 27-36, January 2023., 2023 Abstract Touch voltages are more likely to appear on long‐distance pipelines that lie in shared corridors with transmission lines. The touch voltage level varies with soil resistivity and can become hazardous while maintenance is being undertaken, necessitating risk assessment.

A Study of Lightning Activity over Different Ecological Zones of Nepal [PDF]
arXiv, 2021 In the present work, occurrence of lightning activity over different ecological zones of Nepal has been studied. It has been observed that Lower Tropical zone receives lightning strikes with largest value of density of strikes whereas the Trans-Himalayan zone receives lightning strikes with least value of density of strikes.

Biochemistry and Molecular Biology Education, EarlyView.Abstract Energy is a crosscutting concept in science, but college students often perceive a mismatch between how their biology and chemistry courses discuss the topic. The challenge of reconciling these disciplinary differences can promote faulty reasoning—for example, biology students often develop the incorrect idea that breaking bonds is exothermic ...

Spatial Variation of the Correlated Color Temperature of Lightning Channel [PDF]
arXiv, 2014 In present work, we propose the analysis method of lightning based on the color analysis. We analyzed the digital still images in which the cloud-to-ground (CG) and intracloud (IC) lightning flashes are shown. Applying some digital image processing techniques, we extracted lightning channels.

Multi-scale Residual Transformer for VLF Lightning Transients Classification [PDF]
arXiv, 2023 The utilization of Very Low Frequency (VLF) electromagnetic signals in navigation systems is widespread. However, the non-stationary behavior of lightning signals can affect VLF electromagnetic signal transmission. Accurately classifying lightning signals is important for reducing interference and noise in VLF, thereby improving the reliability and ...

Lessons in love: Countering student belief in romantic love myths
Journal of Philosophy of Education, Volume 56, Issue 5, Page 739-751, October 2022., 2022 Abstract The Department for Education recently administered new Relationships and Sex Education (RSE) guidance, one of the aims of which is to foster students’ ability to develop and maintain healthy romantic relationships in adulthood. However, while an education aimed at developing this capacity in young people is welcomed, the RSE guidance does not ...
