Examining the feasibility of current spiral curve design controls for LiDAR‐based automated vehicles

IET Intelligent Transport Systems, 2023
Enabling large‐scale deployment of automated vehicles (AVs) in the near future requires answering the question firstly: whether AVs could safely adapt to as‐built road geometry?

Analytical Method for 3-D Stopping Sight Distance Adequacy Investigation [PDF]

Journal of Civil Engineering and Architecture, 2015
The adopted 2-D SSD (stopping sight distance) adequacy investigation in current design practice may lead to design deficiencies due to inaccurate calculation of the available sight distance. Although this concern has been identified by many research studies in the past, none of them suggested a comprehensive methodology to simulate from a 3-D ...

Investigation on tunnel stability considering pipe‐roof support with transparent soil technology

Deep Underground Science and Engineering, EarlyView.
This study integrates transparent soil technology, 3D reconstruction and numerical simulation to captures the full‐field deformation of shield tunnel instability. Results demonstrate that pipe‐roof support enhances stability via the “soil‐arching barrier effect,” effectively restraining failure wedge development by extending stress transfer paths ...

Keeping their powder dry: Purity, pollution, and handgun ownership among Jewish women in Israel

Feminist Anthropology, EarlyView.
Abstract This article examines the gendered practices through which Jewish women in Israel experience and negotiate personal handgun ownership in everyday life. Drawing on interviews, participant observation in gun‐related spaces, and analysis of women‐only online forums, we explore the expanding participation of Jewish women in civilian gun ownership,
