Investigation of the Evolution Mechanism and Multiphysics Coupling in Tree‐Contact Single‐Phase‐to‐Ground Fault

open access: yesHigh Voltage, EarlyView.
ABSTRACT Tree‐contact single‐phase‐to‐ground fault (TSF) is a common and hazardous type of failure in distribution networks. TSF is likely to occur when overhead conductors contact moist tree branches, potentially leading to insulation breakdown, posing serious threats to grid safety.

Measurement of Fuel Concentration Profile at Leading Edge of Lifted Flame with Acetone Laser-Induced Fluorescence

open access: yesJournal of Thermal Science and Technology, 2009
This is a study of the leading-edge characteristics of a methane-air triple flame. Few experiment results are available for physical examination of such characteristics, so further experimental investigations are strongly needed to understand the ...

‘Enthusiasts’ and ‘Fanatics’: The Decembrists as a Case Study in French Influence on Russian Culture, Emotions and Thought

open access: yesHistory, EarlyView.
Abstract Participants in Russia's 1825 Decembrist uprising against the Tsarist regime were, quite literally, a case study in French cultural influence upon Russia. This is particularly true as it relates to Russia's emotional cultures. Although this has not, traditionally, been the primary focus of historical analysis of this event (in Soviet or ...

Flamelet/progress variable modelling of turbulent non-premixed cool flames of dimethyl-ether/methane mixtures

open access: yesGreen Energy and Resources
In present work, the turbulent non-premixed cool flames of dimethyl-ether (DME)/methane mixtures are studied within the framework of flamelet/progress variable modelling and chemical kinetic analyses.

MIRACLE URBANIZATION: Spatial Production and Political Legitimation in the Sochi 2014 and Beijing 2022 Olympics

open access: yesInternational Journal of Urban and Regional Research, EarlyView.
Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

Scalable Computation of Topological Abstractions for Scalar Data

open access: yesComputer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Assessment of implementation variants of conditional scalar dissipation rate in LES-CMC simulation of auto-ignition of hydrogen jet

open access: yesArchives of Mechanics, 2013
In this paper the large eddy simulation (LES) and conditional moment closure (CMC) combustion model have been applied for modelling of auto-ignition of hydrogen jet issuing into a hot ambient co-flow.

Advances in 4D Representation: Geometry, Motion, and Interaction

open access: yesComputer Graphics Forum, EarlyView.
We survey 4D representation through three key pillars — geometry, motion, and interaction — offering a selective, representation‐centric perspective to guide researchers in choosing and customizing the right 4D representation for their tasks. Abstract We present a survey on 4D generation and reconstruction, a fast‐evolving subfield of computer graphics

“Go Ahead and Bring Me Up on Charges—The Rocks Will Sing Out”: Organizational Structure, Ally Activism, and the Struggle for Marriage Equality in the UMC

open access: yesJournal for the Scientific Study of Religion, EarlyView.
ABSTRACT After decades of struggle, the United Methodist Church (UMC) removed all LGBTQ‐restrictive language from its Book of Discipline in 2024, overturning exclusionary policies that forbid same‐sex weddings and the ordination of LGBTQ+ clergy. This research sheds light on the activism that preceded institutional change within the UMC.

Effect of Pressure, Environment Temperature, Jet Velocity and Nitrogen Dilution on the Liftoff Characteristics of a N2-in-H2 Jet Flame in a Vitiated Co-flow

open access: yesEurasian Chemico-Technological Journal, 2014
The CO2 emission prevention advantage of generating power with high hydrogen content fuels using gas turbines motivates an improved understanding of the ignition behavior of hydrogen in premixed and partially premixed environments.
