The Impact of Cannibalization as a Reverse Logistics Process on the Public Transport System: Vilnius City Case Study

Background: Cannibalization, defined as the recovery of serviceable components from one vehicle for use in another, is an underexplored reverse logistics practice in public transport maintenance. This study aims to analyze the role of cannibalization in public transport systems a...

Examination of the Implementation Processes of Rail Vehicle Onboard Systems for Infrastructure Monitoring

Abstract The authors examined the process of creating and launching railway infrastructure condition measurement equipment in a pilot project. During this process, three stages were implemented when multicriteria decision-making was applied. First, the type of sensors was selecte...

Photovoltaic power forecasting: A comprehensive review and taxonomy of forecasting methods

Photovoltaic (PV) power forecasting is a foundational capability for operating power systems with high shares of variable renewable generation. However, the methodological landscape is fragmented across physical-based models, statistical time-series approaches, machine learning (...

Artificial Intelligence Based Framework for Student Engagement Assessment in Classroom Environments

Student distraction remains a critical barrier to effective learning in classroom environments, yet existing detection methods relying on manual observation or post-session feedback are inherently subjective, time-intensive, and ill-suited for real-time adaptive teaching. This st...

Spatium Mutans: Event‐Level Chronotopic Alignments and Moral Deontic Stance in Mobile Interviews With Border‐Crossing Facilitators

ABSTRACT This article examines how two border‐crossing facilitators construct moral legitimacy across four recorded journey segments—two outbound and two return—between Italy and Austria. Mobility provides the organizing condition: journey direction, passenger copresence, and the...

Interactions Among MWCNTs, an Air-Entraining Agent, and Superplasticizers in Lightweight Cementitious Materials

This study examined the combined effects on highly foamed cementitious materials of varying concentrations of multi-walled carbon nanotubes (MWCNTs), an air-entraining agent (AEA), and three superplasticizers (SPs): a lignosulfonate-based superplasticizer (SP-LS), a polyacrylate-...

A Formal Trustworthiness Construct for Large Language Model-Based Test Generation: A Multidimensional Index Empirically Evaluated Through a Multi-Agent Study

Software code testing remains a critically important but labour-intensive process in software quality assurance. Existing research evaluates large language model (LLM)-based unit test generation using various quality metrics, such as correctness, coverage, mutation score, and tes...

Adolescents at the crossroads: genetic associations between psychotic symptoms and antisocial traits

<title>Abstract</title> Antisocial behaviour in youth has serious consequences at individual and societal level. Adolescence is also a critical period for the emergence of prodromal psychosis symptoms. Their co-occurrence may aggravate aggression and lead to severe adverse outcom...

Charting the future of auditing: a global latent Dirichlet allocation-based exploration (1988–2024)

Abstract This study aims to identify key themes and research trends in auditing through a comprehensive analysis of 5961 Scopus-indexed articles published from 1988 to 2024. Latent Dirichlet allocation (LDA) was employed to uncover dominant themes and associated conceptual groupi...

Novel investigation on pine oil-diesel blends enriched with hydrogen and alumina nanoparticles used for diesel engines

This study investigates the performance, combustion, and emission characteristics of a diesel engine operating on a novel dual-fuel combination consisting of pine oil–diesel blends enriched with hydrogen and alumina (Al2O3) nanoparticles. A baseline blend of 80% pine oil and 20%...
