Research on the lightweight detection method of rail internal damage based on improved YOLOv8

Journal of Engineering and Applied Science
To address the challenges of high computational costs, large storage demands, and low detection accuracy in internal rail damage identification, we propose a lightweight detection model, GhostMicroNet-YOLOv8n, as an enhancement of YOLOv8n.

Reliability of rail transverse flaw detection by means of an embedded ultrasonic based device

MATEC Web of Conferences, 2018
The main causes of train derailment are related to rail defects such as head surface defects, horizontal defects, vertical longitudinal split defects, star cracks at colt holes and diagonal crack in web. The most adverse form of these defects consists of

BEHIND THE FACES OF AESTHETICIZED URBANISM IN TUNXI, CHINA

International Journal of Urban and Regional Research, EarlyView.
Abstract Urban policy in China has become increasingly predicated on securing an approved aesthetic that reflects ideological campaigns and political programmes. In highlighting the role of the aesthetic in Chinese urbanism, this article argues that the party‐state draws on an aesthetic palette that places the contemporary urban landscape in a ...

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

“Tragic,” “Torment,” and “Torture”: Leadership as Fertile Ground for Women's Organizational Misogyny

Gender, Work &Organization, EarlyView.
ABSTRACT This feminist study explores women's hostilities toward women in UK leadership as organizational misogyny. Organizations are mostly silent about misogyny, and gender studies have yet to empirically interrogate organizational misogyny and expose it as a critical method of women's oppression. Here, we explore women's organizational misogyny (WOM)

The Effect of Mine‐Related Groundwater Use and Management on Surface Water in the Middle Humboldt River Basin

Groundwater, EarlyView.
Abstract The Humboldt River, in Northern Nevada, USA, is a source of water for agricultural, municipal, and industrial uses. Mining has been active in Nevada since the 1800s. The recognition that groundwater withdrawal for many purposes—including mining—has the potential to deplete streamflow has prompted studies of the Humboldt River Basin.
