Abstract
Growing urbanisation, the development of smart cities, and environmental concerns have driven the implementation of advanced technologies and the modernisation of transport systems. Electric motorcycles have emerged as an effective solution for mobility, but they also present specific challenges, particularly related to the mode of riding, which is more complex than that of other vehicles and requires greater attention, skill, and preparation. Therefore, the interaction between the rider and the support system must be carefully designed, with particular emphasis on the interface and the adaptation of route information. This interface should be intuitive, accessible, and capable of presenting relevant information in a clear and objective manner, minimising distractions while riding. In addition, it must be adaptable to user preferences, allowing for customisation such as colour themes, levels of detail in the information displayed, or specific notifications regarding adverse weather and road conditions. Adapting route information provides a more efficient, safe, and satisfactory user experience. It enables riders to access personalised information, continuously updated in real time and tailored to the situation and their specific needs, including traffic conditions, road surface state, and weather conditions. This optimisation leads to better time management, energy consumption, and overall ride quality, enhancing urgent and non-urgent services. Moreover, integrating clearly and objectively features such as voice commands and compatibility with mobile or wearable devices (e.g., smartwatches) can facilitate real-time interaction without compromising safety. The interface should also offer advanced functionalities in line with technological developments and user needs, adapting to each rider’s specific requirements. This not only improves the individual experience but also promotes efficiency and sustainability, contributing to the advancement of smart cities and innovative mobility solutions. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2026.

Abstract
The Benefit of the Doubt (BoD) is a non-parametric frontier model derived from Data Envelopment Analysis (DEA), used to construct composite indicators in various sectors of economic activity, with a particular focus on macroeconomic assessments. Based on documents published in the Web of Science from 1991 to 2025, we conduct a systematic bibliometric review on this topic, proposing future research directions derived from the bibliographic coverage of the most recurrent concepts, areas, and problems addressed in the current BoD literature. We identify core publication networks for non-parametric frontier composite indicators, highlighting trends, hot topics, and clusters of applications. As a result, we offer three different and comprehensive BoD research agendas based on a practical knowledge discovery exercise from expert knowledge and Large Language Models (LLM), highlighting attractive topics, theoretical contributions, concepts, methods, and potential applications. © 2025 The Author(s)

Abstract
This study highlights the critical role of Large Language Model (LLM) in simplifying technical content and integrating visual data for accessible communication. It compares GPT-4 and Llama-3.2-90b-Vision-Preview, focusing on readability, semantic similarity, and multimodal interpretation using robust metrics like Flesch Reading Ease, Gunning Fog Index, and CLIP Score. GPT-4 retains key information and achieves high semantic and textual integration scores, making it more suitable for complex technical scenarios. Furthermore, LLaMA prioritizes readability and simplicity, outperforming in generating accessible captions. Both models show optimal performance with a temperature setting of 0.5, balancing simplicity and meaning preservation. The research underscores LLM potential to democratize technical knowledge across disciplines but notes precision and multimodal integration limitations. Future directions include fine-tuning for domain-specific applications and expanding input modalities to enhance accessibility and efficiency in real-world technical tasks.

Abstract
This study presents an innovative approach to assessing service quality in the water supply and wastewater treatment sectors, using directional Benefit-of-the-Doubt (BoD) models tailored to regulator needs. Unlike previous research, this work integrates the regulator preferences throughout the entire evaluation process, from selecting key performance metrics to determining reference weights and validating results through sensitivity analyses. A new index for the Assessment of the Quality of Services (AQS) was constructed using a set of indicators chosen by the regulator, ensuring a direct alignment with regulatory priorities. Additionally, the study examines the relationship between service quality and cost efficiency, the latter computed using the Data Envelopment Analysis (DEA) methodology, to address the inherent tension in the water sector between these often conflicting goals. By providing a comprehensive comparison of wholesale utilities' performance, the findings highlight that cost efficiency and service quality do not always align. This underscores the need for a balanced regulatory approach that fosters service quality improvements while maintaining cost control, promoting sustainable and effective management of the sector.

Abstract
This paper provides an overview of the application potential of artificial intelligence (AI) in power systems and points towards prospective developments in the fields of AI that are promised to play a transformative role in the evolution of power systems. Among the basic requirements, also imposed by regulation in some places, are trustworthiness and interpretability. Large language models, foundation models, as well as neuro-symbolic and compound AI models, appear to be the most promising emerging AI paradigms. Finally, the trajectories along which the future of AI in power systems might evolve are discussed, and conclusions are drawn.
