A grasshopper-based computational framework for geometry analyses based on the ...
Carvalho, Diogo; Oliveira, João; Clemente, VioletaThis paper addresses the complexities in the Roller Tool Forming process, specifically the jollying method for small axial ceramic products like vases and cups. The manufacturing intricacies, including material shrinkage and stress due to curvature changes, often lead to iterative prototyping and resource consumption. To address these challenges, the paper showcases how computational design can enhance the desi...
A Importância de uma Unidade de Insuficiência Cardíaca na Redução do Número de ...
Oliveira, João; Alvarelhão, José; Pintor, Inês; Neves, JoanaIntrodução: A insuficiência cardíaca (IC) e uma síndrome clinica complexa e multifatorial com elevada morbimortalidade e grandes custos nos cuidados de saúde. A integração do doente com IC em programas especiais e multidisciplinares de seguimento visa melhorar a qualidade de vida reduzindo eventos adversos e custos económicos. O objetivo deste trabalho e analisar o impacto de uma unidade de IC do Serviço de Med...

Respiratory telerehabilitation: user experience and satisfaction with the program
Reis, Neuza; Costa Dias, Maria José; Sousa, Luís; Oliveira, João; Rico, Miguel Toscano; Baixinho, Cristina Lavareda; Henriques, Maria AdrianaBackground The rise of telehealth in geriatric care is an inexorable movement toward adapting to global digitalization trends, in terms of both technology and implementation experiences, with clear gains for health systems and citizens. A literature review shows that the older population, with lower levels of digital literacy, faces specific challenges with this type of service. The aim of this study was to und...
A BiLSTM approach to outfit compatibility and image similarity
Silva, Luís; Oliveira, Francisco; Gomes, Ivan; Araújo, C. Mendes; Oliveira, JoãoIn the ever-evolving world of fashion, building the perfect outfit can be a challenge. We propose a fashion recommendation system, which we call Visual Search, that uses computer vision and deep learning to ensure a coordinated set of fashion recommendations. The system allows users to upload a single photo of their outfit, where a pretrained YOLO model, further fine-tuned on a dataset of labeled clothing items...
Threat Modeling a Health Web3 DApp
Gomes, Ricardo; Dinis, Daniela; Oliveira, João; Maximiano, Marisa; Távora, Vítor; Antunes, Carlos Machado; Dias, Manuel; Bezerra, Ricardo CorreiaThe healthcare sector increasingly explores Distributed Ledger Technology (DLT) and Health Web 3.0 Decentralized Applications (DApps) as promising solutions for patient-centric data management, data sovereignty, and privacy-preserving systems. Despite significant research at the intersection of blockchain and healthcare, current efforts predominantly address isolated technical challenges—focusing narrowly on sp...
Engineering Pb-free relaxor ferroelectric thin films for low voltage energy sto...
Ribeiro, Duarte J. M.; Nair, Surya Kiran Puravankara; Ravikumar, Jayakrishnan AMpattu; Oliveira, João; Magagnin, Grégoire; Albertini, DavidPulsed power technologies demand dielectric capacitors that possess a high energy storage density and efficiency at low applied electric fields/voltages. In this work, we engineered the morphology of lead-free \( 0.85[0.6\text{Ba}(\text{Zr}_{0.2}\text{Ti}_{0.8})\text{O}_3–0.4(\text{Ba}_{0.7}\text{Ca}_{0.3})\text{TiO}_3]–0.15\text{SrTiO}_3 \) (BZCT–STO) epitaxial thin films, fabricated using the pulsed laser dep...

Monteiro, Sara; Salazar, Luís; Oliveira, João; Souto, Mariana; Morais, Lurdes; Ramos, Ana; Ferreira-Magalhães, ManuelIntroduction: With the emergence of the COVID-19 pandemic, several non-pharmacological measures were adopted to prevent and control the transmission of SARS-CoV-2. Objective: To compare pediatric hospitalizations for acute respiratory infections (ARIs) before and after the emergence of SARS-CoV-2. Materials and Methods: This was a retrospective, observational study of admissions for ARIs in the pediatric ward o...
The progressive pilgrim: real and mythical Indian geography in the contemporary...
Oliveira, JoãoSeveral English-language adaptations of the Indian epic Rāmāyana have been published since the beginning of the21st century. The epic has been regarded and recreated asa metonym for the Indian nation. Contemporary versionshave often referred to Indian geography and have tried topoetically or literally associate mythic spaces with real ones.In this paper, I use discourse analysis in order to study someof the mos...
A regression deep learning approach for fashion compatibility
Silva, Luís; Gomes, Ivan; Araújo, C. Mendes; Cepeda, Tiago; Oliveira, Francisco; Oliveira, JoãoIn the ever-evolving world of fashion, building the perfect outfit can be a challenge. We propose a fashion recommendation system, which we call Visual Search, that uses computer vision and deep learning to ensure that it has a co-ordinated set of fashion recommendations. It looks at photos of incomplete outfits, recognizes existing items, and suggests the most compatible missing piece. At the heart of our syst...
