Use of programming aids in undergraduate courses
Peixoto, A.; Glória, A.; Silva, J. L.; Pinto-Albuquerque, M.; Brandão, T.; Nunes, L.The use of external tips and applications to help with programming assignments, by novice programmers, is a double-edged sword, it can help by showing examples of problem-solving strategies, but it can also prevent learning because recognizing a good solution is not the same skill as creating one. A study was conducted during the 2superscript{nd} semester of 23/24 in the course of Object Oriented Programming to...
Social support for functional dependence, activity patterns, and chronic pain o...
Bernardes, S. F.; Brandão, T.; Matos, M. O. de.; Ferreira-Valente, A.Objective: Received social support undermining engagement in life activities of individuals with chronic pain (e.g., solicitousness, support for functional dependence) is consistently correlated with worse physical functioning, pain severity, and disability. Whether such responses lead to worse pain outcomes (operant model of pain) or the latter lead to more supportive responses undermining activity engagement ...
Wildfire detection with deep learning—A case study for the CICLOPE project
Gonçalves, A. M.; Brandão, T.; Ferreira, J. C.In recent years, Portugal has seen wide variability in wildfire damage associated to high unpredictability of climatic events such as severe heatwaves and drier summers. Therefore, timely and accurate detection of forest and rural wildfires is of great importance for successful fire containment and suppression efforts, as wildfires exponentially increase their spread rate from the moment of ignition. In the fie...
Deep learning for automatic calcium detection in echocardiography
Elvas, L. B.; Gomes, S.; Ferreira, J. C.; Rosário, L. B.; Brandão, T.Cardiovascular diseases are the main cause of death in the world and cardiovascular imaging techniques are the mainstay of noninvasive diagnosis. Aortic stenosis is a lethal cardiac disease preceded by aortic valve calcification for several years. Data-driven tools developed with Deep Learning (DL) algorithms can process and categorize medical images data, providing fast diagnoses with considered reliability, t...

Vargas-Moniz, M.J.; Queirós. F; Almeida-Rocha, T.; Belo, S; Brandão, T.; Gouveia, M. J; Loureiro, F; Martins, A. C.; Neto, DIntrodução: Este poster foi desenvolvido pelo projeto “UNI_R: Resposta Integrada na Promoção Saúde Mental no Ensino Superior” no âmbito do convite da Direção Geral do Ensino Superior (DGES) para a conferência "Inovação e Bem-estar para o Sucesso: Inovação Pedagógica, Saúde Mental e Sucesso no Ensino Superior" na Universidade de Coimbra, nos dias 24 e 25 de outubro de 2024. Objetivo: Este poster procurou apresen...
The portuguese version of the Emotion Regulation of Others and Self (EROS) in a...
Brandão, T.; Teixeira, R.J.; Pereira, AnabelaThe Emotion Regulation of Others and Self Scale (EROS) is commonly used to measure individual differences in the use of strategies to regulate one’s own and other people’s emotions. This study aimed to examine its psychometric properties and measurement invariance across sex in a Portuguese clinical sample. For this purpose, we tested the factorial structure of the EROS in a sample of 390 adults (259 women; Mag...
Occlusion-aware pedestrian detection and tracking
Correia, S.; Mendes, D.; Jorge, P.; Brandão, T.; Arriaga, P.; Nunes, L.This paper proposes an occlusion-aware mechanism, used on a framework for detecting and tracking pedestrians in videos acquired from surveillance cameras, which includes the extraction of trajectory points, estimation of walking velocities, detection of groups, and projection of the final trajectories into a 2D plan. The occlusion-aware mechanism is introduced in order to manage irregularities in the pedestrian...
Automatic calcium detection in echocardiography based on deep learning: A syste...
Gomes, S.; Elvas, L. B.; Ferreira, J.; Brandão, T.The diagnosis of many heart diseases involves the analysis of images from Computed Tomography (CT) or echocardiography, which is mainly done by a medical professional. By using Deep Learning (DL) algorithms, it is possible to create a data-driven tool capable of processing and classifying this type of image, to support physicians in their tasks, improving healthcare efficiency by offering faster and more accura...
Multi-camera person re-identification based on trajectory data
Mendes, D.; Correia, S.; Jorge, P.; Brandão, T.; Arriaga, P.; Nunes, L.This study presents a trajectory-based person re-identification algorithm, embedded in a tool to detect and track customers present in a large retail store, in a multi-camera environment. The customer trajectory data are obtained from video surveillance images captured by multiple cameras, and customers are detected and tracked along the frames that compose the videos. Due to the characteristics of a multi-came...
Deep learning-based graffiti detection: A study using Images from the streets o...
Fogaça, J.; Brandão, T.; Ferreira, J.This research work comes from a real problem from Lisbon City Council that was interested in developing a system that automatically detects in real-time illegal graffiti present throughout the city of Lisbon by using cars equipped with cameras. This system would allow a more efficient and faster identification and clean-up of the illegal graffiti constantly being produced, with a georeferenced position. We cont...
