Models for Lateral Dynamic Interaction of High-Speed Trains and Bridges [PDF]

, 2011
In this work a methodology for analysing the lateral coupled behavior of large viaducts and high-speed trains is proposed. The finite element method is used for the structure, multibody techniques are applied for vehicles and the interaction between them ...

“There Are Places Full of Beauty”: Desettling High School Students' Scientific Writing

Science Education, EarlyView.
ABSTRACT This study contributes to desettling and expanding expectations about the forms of scientific language that belong in students' scientific writing. The primary empirical focus is the analysis of 52 high school student abstracts articulating community‐based investigations, submitted as part of their participation in a student conference in a ...

Mechanical properties analysis of the interspersed replacement of timber sleepers with bamboo-based composite sleepers on open bridge deck

Scientific Reports
Due to the discrete deterioration characteristics of timber sleepers on open bridge deck, continuous replacement is difficult. New bamboo-based composite sleepers (BCSs) offer excellent performance at a low price, making them an ideal alternative to ...

Leveraging the Potential of Public Food Procurement to Achieve Multiple Food System Outcomes: Insights From a Policy Analysis in Australia

Sustainable Development, EarlyView.
ABSTRACT Government food procurement investment offers significant potential to advance health and sustainability goals; yet, integrating these dimensions into policy design has proved challenging. We mapped and analysed 38 food procurement and catering‐specific policies in Australia to identify ways to strengthen policy design: 20 governing ...

Enhancing LoRA Model Serving Capacity via Adaptive Operator Scheduling for Multi-Tenancy on GPU

IEEE Access
Low-Rank Adaptation (LoRA) has garnered increasing attention for effectively fine-tuning large language models (LLMs) with limited resources. Nonetheless, conventional approaches that cater to multiple LoRA models independently lead to redundant ...

High‐Speed Rail and Spatial Equity: Unpacking the Sustainability Paradox of Land Use and Fiscal Pressure in County‐Level Cities

Sustainable Development, EarlyView.
ABSTRACT Infrastructure‐led development in rapidly urbanizing economies often generates accessibility gains that fail to translate into balanced urban outcomes, particularly when local fiscal institutions redirect those gains toward revenue‐generating land uses. Filling this gap, especially in fiscally constrained county‐level cities where land finance

High speed/high capacity railway and regional development - evaluation of effects on spatial accessibility [PDF]

In the last decade the theme of high speed infrastructure in Italy has been deeply debated, with different political and technical opinions, which have expanded the time for projects and constructions. As a consequence of this long debate, a redefinition

Efficient Harvesting of Irregular and Low‐Frequency Mechanical Energy via Hybridized Electromagnetic‐Triboelectric Systems

Small, EarlyView.
ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Greenway development and gentrification

Southern Economic Journal, EarlyView.
Abstract This paper presents research on expanding access to green spaces in developed areas. Critics claim greenway projects lead to gentrification by increasing the demand for housing and pushing out residents in nearby neighborhoods. We look for evidence of this phenomenon using a sorting model and panel data on aggregate populations in Atlanta ...
