A Paleotectonic Atlas of the African Plate: Permian to Recent

Journal of Petroleum Geology, Volume 48, Issue 4, Page 231-279, October 2025.
ABSTRACT The fragmentary release of petroleum data defining the deep structure and stratigraphy of African basins has been integrated with existing literature to compile 19 tectonic maps over key geological intervals from Permian to Recent times. African plate margins range in their age of opening from Late Triassic (off Lebanon), through Early/Middle ...

Common Visual Representations as a Source for Misconceptions of Preservice Teachers in a Geometry Connection Course [PDF]

, 2019
In this paper, we demonstrate how atypical visual representations of a triangle, square or a parallelogram may hinder students’ understanding of a median and altitude.

Molecular cloud distance determination from deep NIR survey extinction measurements

, 2010
Using near infrared UKIDSS Galactic Plane Survey data, we make extinction measurements to individual stars along the same line of sight as molecular clouds.

Duval Triangle-Based Dissolved Gas Analysis using GNU Octave for Transformer Fault Detection

Aviation Electronics, Information Technology, Telecommunications, Electricals, Controls
Transformers are vital components in electrical power systems. However, they are also susceptible to various types of failures, including thermal and electrical faults caused by the formation of electromotive force, which, if left unaddressed, may result

Bimodal Slip Segmentation of the SW Hellenic Megathrust Revealed by the Mw 6.8 Methoni Earthquake Sequence and Tomography

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract The influence of geological and structural heterogeneity on the megathrust slip behavior in subduction zones has been widely discussed for both the lower‐ and upper‐plates. In this work, we present OBS local earthquake tomography on the outer forearc domain of the SW Hellenic subduction zone performed with the aftershocks of the 2008 Mw 6.8 ...

A systematic study of Lyman-Alpha transfer through outflowing shells: Model parameter estimation

, 2015
Outflows promote the escape of Lyman-$\alpha$ (Ly$\alpha$) photons from dusty interstellar media. The process of radiative transfer through interstellar outflows is often modelled by a spherically symmetric, geometrically thin shell of gas that scatters ...

Interpreting Ice Anisotropy of Greenland's Fastest Outlet Glacier Using Basal Icequakes

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract Ice anisotropy can have significant impact on ice rheology and flow dynamics. However, a lack of in situ measurements limits the validation and incorporation of anisotropy, so most ice flow models assume isotropic ice. Especially observations of anisotropy in fast‐flowing ice streams are scarce.

An adaptive multi-fuzzy logic model for diagnosing transformer faults using dynamic weight optimization

e-Prime: Advances in Electrical Engineering, Electronics and Energy
Dissolved gas analysis (DGA) is crucial for diagnosing early power transformer failures. Traditional DGA interpretation methods like Duval Triangle, IEC ratio, Roger ratio, Doernenburg ratio and Key Gas are inconsistent and vary in accuracy, especially ...

A novel transformer health state direct prediction method based on knowledge and data fusion‐driven model

High Voltage, Volume 10, Issue 3, Page 710-725, June 2025.
Abstract Predicting the future health state of a transformer can offer early warning of latent defects and faults within the transformer, thereby facilitating the formulation of power outage maintenance plans and power dispatch strategies. However, existing prediction methods based on the structure of ‘splicing prediction and diagnosis method’ suffer ...
