Auto‐ISC: Inter‐Sample Contrastive Learning for Automated Curve Angle Calculation From Ultrasound

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Scoliosis assessment has been increasingly supported by AI‐assisted tools, enabling more efficient and standardised clinical workflows. However, existing ultrasound‐based pipelines often suffer from limited generalisation and unstable performance.

Optimisation or Learning? Appropriate Choice of Models and Methods for Sequential Decision‐Making in Power System Operation

Energy Internet, EarlyView.
ABSTRACT Power system operation is inherently a sequential decision‐making problem, traditionally addressed through optimisation models built upon high‐quality load forecasts. However, the rapid proliferation of renewable generation and price‐responsive demands, such as electric vehicles and merchant energy storage, has introduced multiple sources of ...

Velocity‐based stowage policy for a semiautomated fulfillment system

Production and Operations Management, EarlyView., 2022
Abstract Online retail fulfillment is increasingly performed by semiautomated fulfillment systems in which inventory is stored in mobile pods that are moved by robotic drives. In this paper, we develop a model that explores the benefits of velocity‐based stowage policies for semiautomated fulfillment systems, also known as robotic mobile fulfillment ...

HEAVY TRAFFIC ANALYSIS IN QUEUEING SYSTEMS

Studia Universitatis Moldaviae: Stiinte Umanistice, 2008
The traffic intensity is defined in the classical theory of queueing systems as the ratio of the expected service time and the expected interarrival time and is an important measure of the system performance.

On Demand Connectivity Sharing: Queuing management and load balancing for User-Provided Networks

, 2011
We introduce the concept of "On Demand Connectivity Sharing", which we build on top of User-Provided Networks (UPNs). UPNs were recently proposed as a new connectivity paradigm, according to which home-users share their broadband Internet connection with

From Tap Water Access to Income‐Generating Work Time: Evidence From Rural China

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This study examines whether household tap water access affects income‐generating work time among employed rural adults in China. While existing studies have mainly examined the effects of improved water access on employment participation, off‐farm transition and household income, this paper focuses on the intensive margin of labour supply ...

‘A Fairly Average “White Middle‐Class” Species of Lesbian’: Lorna Gulston, Ireland and the Early Anglophone Lesbian Press, 1965–1980

Gender &History, EarlyView.
ABSTRACT This article examines the published writings of Lorna Gulston (c. 1932–2023), a hitherto unknown Northern Irish civil servant who wrote many articles for the earliest British lesbian magazines such as Arena Three, Sappho and Sequel. In doing so, the article asks: How did Gulston find her way onto the pages of these pioneering magazines?
