Global distribution of winter lightning: a threat to wind turbines and aircraft

Lightning is one of the major threats to multi-megawatt wind turbines and a concern for modern aircraft due to the use of lightweight composite materials. Both wind turbines and aircraft can initiate lightning, and very favorable conditions for lightning

Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

High Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

PowerGPT‐R1: Vision‐Language Reinforcement Fine‐Tuning With Verifiable Reward for Power Inspection

High Voltage, EarlyView.
ABSTRACT Vision‐driven intelligent power inspection systems have long faced the challenge of scarce high‐quality datasets in specialised domains, leading to limited performance of traditional deep learning methods (e.g., Faster‐RCNN) in few‐shot learning scenarios. Recent breakthroughs in language models, particularly the open‐source DeepSeek‐R1 model,

Research on Embodied Intelligence Technology for Electric Power Equipment Based on Large‐Scale Pre‐Trained Models

High Voltage, EarlyView.
ABSTRACT With the development of electric power artificial intelligence (AI) technology, many complicated challenges emerged during application. Traditional AI algorithms work well in specialised tasks such as detection and classification. However, they are unlikely to solve general problems.

Conductivity Analysis and Thermoelectric Behaviour of Larch Standing Trees Under Lightning Currents: Role of Moisture Distribution and Carrier Motion

High Voltage, EarlyView.
ABSTRACT The direct effects of lightning strikes on forest combustibles form the foundation for predicting lightning‐induced forest fires. Accurate assessment of lightning impact is hindered by limited knowledge of the conduction characteristics of standing larch trees.

Lightning Impulse Ageing of HDPE

, 2009
This work is concerned with the hypothesis that lightning impulses can lead to accelerated ageing of extruded polymeric cables. The behaviour of an insulation material when suffering lightning impulses is different from that for DC or power frequency ...

The Constellation: A Reappraisal of Walter Benjamin's Influence on Theodor W. Adorno

Constellations, EarlyView.
ABSTRACT In the 1920s and 1930s, Walter Benjamin and Theodor W. Adorno both sought to develop a notion of Darstellung—of philosophical presentation or representation—that could provide an alternative to the classically idealist tendency to subsume objects under abstract concepts.

The Political Ecology of the ‘New’ Feminism in Late‐1990s Britain

Gender &History, EarlyView.
ABSTRACT The 1990s were a vexed time for feminists in Britain. Cultural commentators declared that feminism's key battles had been won, and that given women's ascendency across various political and cultural barometers of success, the country was entering a newly ‘postfeminist’ era.

Barbara's Daughters: Women's Boxing and Social Memory in Britain

History, EarlyView.
Abstract A pioneer of post‐war boxing, Barbara Buttrick fought in fairgrounds and on music‐hall stages in Britain and France before making a career in the United States during the 1950s. She fought against practical obstacles, prejudice and discrimination to become the Women's World Flyweight and Bantamweight Champion in 1957. This article examines her
