Disruption, an opportunity to facilitate long-term modal shift to cycling? Stories, lessons and reflections from the COVID-19 pandemic

open access: yesActive Travel Studies, 2023
The study utilises the ‘natural experiment’ of COVID-19 to explore how disruption affected individuals’ perceptions and experiences of cycling, through semi-structured interviews with eight cycle-shop owners and 30 residents in the Liverpool City Region,

A System Dynamics Model of the Modal Shift from Road to Rail: Containerization and Imposition of Taxes

open access: yesJournal of Advanced Transportation, 2019
Over the past decade, intermodal transport focused on reducing external cost, congestion, and carbon dioxide emissions, which have been caused by road transportation.

Towards understanding the design of dual-modal MR/fluorescent probes to sense zinc ions [PDF]

open access: yes, 2014
A series of gadolinium complexes were synthesised in order to test the design of dual-modal probes that display a change in fluorescence or relaxivity response upon binding of zinc.

Leverage Points in Modality Shifts: Comparing Language-only and Multimodal Word Representations

open access: yesProceedings of the 12th Joint Conference on Lexical and Computational Semantics (*SEM 2023), 2023
Multimodal embeddings aim to enrich the semantic information in neural representations of language compared to text-only models. While different embeddings exhibit different applicability and performance on downstream tasks, little is known about the systematic representation differences attributed to the visual modality.

Evaluating the potential for modal shift in last-mile cargo distribution through stochastic programming

open access: yesMaritime Transport Research, 2020
This paper presents a multistage stochastic programming model used to evaluate the potential for obtaining a modal shift from road to sea in the cargo distribution between a regional port and the surrounding customer regions, each with a given (and ...

Life Cycle Assessment of Free-Floating Bike Sharing on Greenhouse Gas Emissions: A Case Study in Nanjing, China

open access: yesApplied Sciences, 2021
The free-floating bike sharing (FFBS) system appears in the form of low-carbon transport mode. Life cycle assessment (LCA) is a method to analyze the environmental impact of FFBS but has rarely considered the trip chain if the intermodal transport modes ...

Fluid-Structure Interaction Simulation of a Coriolis Mass Flowmeter using a Lattice Boltzmann Method [PDF]

open access: yes, 2020
In this paper we use a fluid-structure interaction (FSI) approach to simulate a Coriolis mass flowmeter (CMF). The fluid dynamics are calculated by the open source framework OpenLB, based on the lattice Boltzmann method (LBM). For the structural dynamics
