Evaluating Geometric and Structured Fractal Analysis Methods to Determine the Optimal Approach for Urban Road Network Assessment

Urban networks are often classified as complex elements that influence the growth of cities beyond their boundaries. These networks are analysed using numerous approaches, tools, where fractal dimensions provide quantitative assessment of the spatial organisation. This study applies geometric and structured (network-based) fractal analysis techniques to the road network of Metropolitan City of Cagliari (MCC). It highlights the methodological differences and their implications across diverse f...

Towards a MaaS for all. A Methodology to Identify the Determinants of Autonomy to Enhance the Mobility Capital of Vulnerable Social Groups in Sardinia (Italy)

Mobility as a Service can be a key solution for sustainable and inclusive transport systems. By integrating different transport modes into a unique digital platform that suggests personalised travel solutions, it helps reduce reliance on the private car and provides both efficient and environmentally friendly mobility solutions while also ensuring equal access to mobility. This research explores the applicability of Mobility as a Service (MaaS) for all, looking at the determinants of its use ...

Approaches for quantitative study of divertor heat loads on W7-X

Aimed to show the fusion-reactor relevance of optimized stellarators, Wendelstein 7-X (W7-X) [1], as the world's largest stellarator (plasma volume 30 m(3), major radius 5.5 m, minor radius 0.5 m), completed successfully its first experimental campaign with island divertor in December 2017. To demonstrate the capabilities of steady-state operation with reactor-relevant plasma parameters, island divertor concept is commissioned for a tolerable plasma power and particle exhaust. Pre-defined mag...

Towards In-Context Non-Expert Evaluation of Reflection Generation for Counselling Conversations

Reflection is an essential counselling strategy, where the therapist listens actively and responds with their own interpretation of the client's words. Recent work leveraged pretrained language models (PLMs) to approach reflection generation as a promising tool to aid counsellor training. However, those studies used limited dialogue context for modelling and simplistic error analysis for human evaluation. In this work, we take the first step towards addressing those limitations. First, we fin...

An analysis of EU power system flexibility: storage capacity needs under increasing variable renewable energy sources (VRES) penetration

The increasing penetration of variable renewable energy sources in the energy mix plays a key role in the energy transition but it also poses serious challenges in terms of grid scheduling, regulation, management, and resilience. To cope with the non-programmable nature of renewables, increased generation reserves, ramp rates and curtailments are required to meet the electricity demand with an increasingly uncertain supply and to provide flexibility services to the grid. To avoid excessiv...
