Development of ± 550 kV DC GIS Basin Insulator

open access: yesHigh Voltage, EarlyView.
ABSTRACT The basin insulator is a core component of the insulation system for ± 550 kV gas‐insulated switchgear (GIS). This paper, using a finite element method for multi‐physics simulations of electric–thermal coupling, determines a geometry suitable for the industrial production of ± 550 kV GIS basin insulators.

Chirped pulses, Gauss sums and the factorization of numbers

open access: yes, 2006
International audienceWe present two physical systems which make Gauss sums experimentally accessible. The probability amplitude for a two-photon transition in an appropriate ladder system driven by a chirped laser pulse is determined by a Gauss sum. The

Convergence of Energy Intensity Across ASEAN‐5 Countries: A Wavelet‐Based Perspective

open access: yesNatural Resources Forum, EarlyView.
ABSTRACT The convergence hypothesis, which emphasizes the attainment of income equality among nations, has recently gained prominence in energy studies due to its pivotal role in addressing the pressing challenges at the intersection of economic development and energy sustainability.

Kummer's conjecture for cubic Gauss sums

open access: yes, 2000
Let $S(X,l)=\sum_{N(c)\leq X}\tilde{g}(c)\Lambda(c)(\frac{c}{|c|})^l$ where $\tilde{g}(c)$ is the normalized cubic Gauss sum for an integer $c\equiv 1\pmod{3}$ of the field $\mathbb{Q}(\sqrt{-3})$. It is shown that $S(X,l)\ll_{\varepsilon} X^{5/6+\ep}+|l|

Preemptive Entry and Technology Diffusion: The Market for Drive‐In Theaters

open access: yesThe RAND Journal of Economics, EarlyView.
ABSTRACT This article studies entry preemption in new industries. We first test a key prediction of dynamic entry games: Entry preemption is most relevant in intermediate‐sized markets, where firms face highest uncertainty about future entry. Using US drive‐in theater market (1945–1957) data, we find robust evidence for this non‐monotonic relationship ...

Early Bronze Age Copper Circulation in the Guadalentín and Segura Valleys (SE Spain)

open access: yesArchaeometry, EarlyView.
ABSTRACT Identifying the sources of copper used in Early Bronze Age metalwork from south‐east Spain is key to resolving a long‐running debate concerning centralized control, or lack thereof, over El Argar society's economic organisation. This study provides the first substantial integrated programme of EDXRF and MC‐ICP‐MS analyses for copper‐base ...

Growth and Variation in Fallow Deer (Dama dama L.) From Two Contrasting Habitats in Southern Britain

open access: yesActa Zoologica, EarlyView.
ABSTRACT We have compiled a unique data set on the age, sex, body weight and dimensions of over 500 European fallow deer from two contrasting areas of habitat in southern England: a high‐density managed parkland population and a lower‐density feral woodland one.
