Damage to railway track

Bulletin of the New Zealand Society for Earthquake Engineering, 1969
The Inangahua earthquake brought to a standstill all train operations on the West Coast. The first concern was to inspect the track and bridges to determine whether they were safe for a resumption of train services.

Health in All Policies in Serbian Sectoral Legislation: A Document Analysis

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT Health in All Policies (HiAP) seeks to integrate health considerations across sectors to improve population health and equity. This study examines how HiAP has been operationalised through legal instruments in Serbia, assessing the extent to which legislation incorporates health outcomes, intersectoral governance, equity, use of evidence, and ...

Balancing Productivity, Ecology, and Social Well‐Being: Insights From Three Decades of Farmland Transformation in China

Land Degradation &Development, EarlyView.
ABSTRACT Balancing food security, social equity, and ecological sustainability remains a persistent challenge in global agricultural systems. While economic and ecological aspects of land‐use transitions have been extensively studied, the long‐term dynamics of social functions and their interactions with other functions are less understood.

An urban evolved invasive plant tolerates experimental climate change

PLANTS, PEOPLE, PLANET, EarlyView.
Urbanization may drive invasive species evolution, resulting in greater invasion risks as global conditions change. We compared urban populations of the invasive Erigeron annuus in Zagreb, Croatia, to surrounding rural populations and found that urban‐evolved populations were more tolerant of experimental warming and drought than rural populations ...

Vibration of railway bridges in the audible frequency range

, 2009
The noise level associated with a train travelling on a bridge is normally greater than that for a train travelling on plain track. It is sometimes the bridge noise that causes the highest levels of disturbance to people in the vicinity or triggers ...

Degradation of railway track on heavy haul lines [PDF]

, 2008
The geometric alignment of railway track deteriorates with time, primarily due to the static and dynamic forces exerted by the trains’ wheels on the track. Deterioration of the track’s geometry is called track roughness. The paper reports on the outcomes

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

A Technology‐First Framework for SDG Implementation in Carbon‐Based Economies: Empirical Evidence and Policy Implications

Sustainable Development, EarlyView.
ABSTRACT Only 17% of Sustainable Development Goal indicators are globally on track, yet the structural conditions explaining this failure remain inadequately theorised for fossil‐fuel‐dependent economies. This study develops and empirically tests a four‐layer loop framework of Technology, Well‐being, Social Equity, and Sustainability closing through ...

Study on Performance Optimization and Feasibility of No.9 Turnout with 1520 mm Gauge in China

Applied Sciences
To address the issues of poor geometric dimension retention, short component lifespan, and heavy maintenance workload of the 1520 mm gauge 50 kg/m rail No.9 turnout, a new design was proposed for the 1520 mm gauge 60 kg/m rail No.9 turnout.
