Using virtual reality to explore older adults' preferences for green streets: D...
Eloy, S.; Marques, S.; Samora-Arvela, A.; Montalvão, M.; Silva, N. P. da; Do Bú, E.; Melo, F.; Dias, J.Con l’invecchiamento della popolazione, la progettazione degli spazi pubblici deve rispondere ai bisogni degli anzia- ni per prevenire l’esclusione sociale causata da barriere architettoniche. Tuttavia, l’ambiente costruito esistente ri- mane ancora insufficientemente accessibile, in particolare nella progettazione delle “green streets”, che integrano modalità di mobilità attiva come biciclette e monopattini in...

The impact of sound in people's behaviour in outdoor settings: A study using vi...
Eloy, S.; Andrade, M. A. P.; Dias, L.; Dias, J.This paper presents an analysis of space perception and how visual cues, such as landmarks and sound, are perceived and impact people's behaviour while exploring a given outdoor space. The primary goal of the research is to investigate how auditory sensations and visual stimuli influence people's behaviour in outdoor built environments. Our technique compares people's perception of the built environment in diff...
Data driven spatiotemporal analysis of e-Cargo bike network in Lisbon and its e...
Gil, B.; Albuquerque, V.; Dias, J.; Abranches, R.; Ogando, M.The adoption of more environmentally friendly and sustainable fleets for last-mile parcel delivery within large urban centers, such as e-cargo bikes, has gained the interest of the community. The logistics infrastructure network, had to adapt to the requirements of this new type of fleet, and micro-hubs and nano-hubs emerged. In this paper we tackle spatiotemporal characterization of e-cargo bike fleet behavior...
AI-based aortic stenosis classification in MRI scans
Elvas, L. B.; Águas, P.; Ferreira, J.; Oliveira, J.; Dias, J.; Rosário, L. B.Aortic stenosis (AS) is a critical cardiovascular condition that necessitates precise diagnosis for effective patient care. Despite a limited dataset comprising only 202 images, our study employs transfer learning to investigate the efficacy of five convolutional neural network (CNN) models, coupled with advanced computer vision techniques, in accurately classifying AS. The VGG16 model stands out among the test...
Sustainability measurement in a logistics transportation company
Ferreira, J.; Albuquerque, V.; Pereira, F.; Rocha, J.; Dias, J.We present a preliminary study to the Decision Support System for Sustainable Logistics Transportation, using as case study, the Portuguese logistics transportation company Santos e Vale. In the last five years, it has reduced its fleet carbon footprint by 20%. Our research presents a systematic literature review of indicators, carbon footprint models, and reduction measures associated to the sector, using the ...
Using the impact-WEB_GIS platform to assess the impacts of environmental sustai...
Medeiros, E.; Valente, B.; Pinto, R.; Dias, J.Urban environmental sustainability is a growing concern within the United Nations and the European Union’s ongoing policy agendas to fight climate change. This paper contributes to this debate by presenting the main impacts of the Operational Programme for Sustainability and Use of Resources (POSEUR 2014–2020) in the Lisbon Metropolitan Area (NUTS II). The analysis was completed using the Impact-WEB_GIS platfor...
Cinematic virtual reality: How emotional responses vary across movie genre and ...
Rodrigues, M. B.; Loureiro, S. M. C.; Dias, J.The current study seeks to explore whether virtual reality (VR) can be more effective than traditional 2D in influencing emotional responses (namely, empathy and sympathy), considering different movie genres. A factorial design 2 (movie genre: animation; documentary) x 2 (VR; 2D) between-subjects experiment was employed. A total of 145 participants were recruited. Findings suggest that sympathy and empathy resp...
Health data sharing towards knowledge creation
Elvas, L. B.; Ferreira, J.; Dias, J.; Rosário, L. B.Data sharing and service reuse in the health sector pose significant privacy and security challenges. The European Commission recognizes health data as a unique and cost-effective resource for research, while the OECD emphasizes the need for privacy-protecting data governance systems. In this paper, we propose a novel approach to health data access in a hospital environment, leveraging homomorphic encryption to...
