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 ...

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

IEEJ Transactions on Power and Energy, 2007 This paper describes the theoretical analysis of lightning impulse voltage waveform with an overshoot or oscillation caused by the residual inductance of the impulse generator. The oscillating lightning impulse waveform is expressed by the following formula;vout (t) = A {e-α1t - e-α2t sin(ωt+θ)/sinθ}where A, α1, α2, ω, θ are constants, respectively ...

Can Enterprises Invest Efficiently in Smart Cities?
Accounting &Finance, EarlyView.ABSTRACT The rapid expansion of the digital economy has accelerated smart city (SC) development in China. Using a time‐varying difference‐in‐differences approach, we examine the impact of SC policies on corporate investment efficiency. We document that SC construction significantly enhances investment efficiency, with robust results across multiple ...
