Evaluation of smartphone camera positioning on artificial intelligence pose est...
Oliosi, Eduarda; Ferreira, Soraia; Giordano, Ana Paula; Viveiros, Guilherme; Parraca, José; Pereira, Paulo; Guede-Fernández, Federico; Azevedo, SaloméBackground: Artificial intelligence (AI)–driven pose estimation (PE) offers a scalable and cost-effective solution to track exercises in mobile health apps. However, occlusion, influenced by camera angle and distance, can reduce detection accuracy and repetition counting precision. The influence of smartphone positioning on these performance metrics remains underexplored in controlled studies. Objective: The st...
Artificial intelligence for algorithmic trading digital assets: evidence from t...
Guede-Fernández, Federico; Wagle, Yash; Dias, Pedro; Giordano, Ana Paula; Henriques, Lúcio; Costa, Gonçalo; Azevedo, SaloméIntroduction: The Counter-Strike 2 skin market has developed into a multi-billion-dollar digital asset ecosystem, characterized by high volatility, low liquidity, and pricing inefficiencies that differ substantially from traditional financial markets. Despite the growing economic relevance of virtual items, no previous study has systematically examined the use of artificial intelligence for skin trading. Method...
Legal frameworks for blockchain applications: a comparative study with implicat...
Hafe, Francisco Von; Wagle, Yash; Guede-Fernández, Federico; Giordano, Ana Paula; Silva, Luís; Azevedo, SaloméIntroduction: The decentralised nature of blockchain technology challenges traditional legal frameworks, creating regulatory gaps in asset classification, taxation, and consumer protection. In Europe, divergent approaches, from specialised blockchain laws to adaptations of general financial legislation, hinder cross-border deployment and limit blockchain’s potential. These disparities make compliance difficult ...

A Pragmatic Approach for Web3 Software Quality Assurance Based on International...
Antunes, Rodrigo Cerejo; Freitas, Liliana; Dias, Pedro; Silva, Luís; Guede-Fernandez, Federico; Azevedo, SaloméEnsuring software quality in the Web3 ecosystem presents unique challenges due to its decentralized architecture and evolving technical landscape. While international standards such as the SQuaRE (Systems and software Quality Requirements and Evaluation) framework offer structured approaches for quality assurance, they are often perceived as overly theoretical and not directly applicable to blockchain-based app...

Navigating the tensions of integrating lived experience in participatory health...
Oertzen, Anna-Sophie; Vink, Josina; Odekerken-Schröder, Gaby; Mager, Birgit; Azevedo, SaloméDespite growing interest in participatory approaches to healthcare design, the integration of people's lived experience-direct, first-hand understanding of a certain condition, situation, or identity-remains a key challenge to meaningful participation. Through an interview study with 23 patients, designers, family caregivers, and healthcare professionals involved in participatory healthcare design initiatives, ...
