Accurate rural road network with improved dataset for strengthen wildfire emerg...
Lourenço, Miguel; Caetano, Duarte; Mora, André; Oliveira, Luis; Oliveira, HenriqueWildfires pose significant threats to ecosystemsworldwide, making rapid firefighting responses essential. Firefighters face major challenges in advanced-stage fires, highlighting the need for early detection and improved operational support. However, current rural road mapping methods often fail under occlusions from vegetation and shadows, lack adaptability to wildfire-prone regions, and offer limited automati...
Documenta Filipina
Pinto, Paulo Jorge de Sousa; Lourenço, Miguel; Penalva, Elsa; Pinto, Pedro; Loureiro, RuiDocumenta Filipina – The Philippines in Portuguese Archives and Libraries aims at identifying and gathering the existing information about the Philippines in the most relevant archives and manuscript collections in Portugal, namely in Arquivo Nacional da Torre do Tombo, Biblioteca da Ajuda and Arquivo Histórico Ultramarino, from the 16th to the early 19th century. Its final objective is to present a useful comp...

Tension chord model para cargas alternadas
Lourenço, Miguel; Ferreira, Miguel; Oliveira, Cristina; Almeida, JoãoO Tension Chord Model (TCM) é um modelo de análise para simular o comportamento de um elemento de betão armado, considerando, individualmente, as relações constitutivas de ensaios uniaxiais dos materiais aço e betão, e, com o comportamento conjunto simulado através de uma lei de aderência rígido-plástica simplificada. Neste artigo, o TCM é estendido para situações de cargas alternadas e repetidas, apresentando-...
Automatic rural road centerline detection and extraction from aerial images for...
Lourenço, Miguel; Estima, Diogo; Oliveira, Luís; Mora, André; Oliveira, HenriqueTo effectively manage the terrestrial firefighting fleet in a forest fire scenario, namely, to optimize its displacement in the field, it is crucial to have a well-structured and accurate mapping of rural roads. The landscape’s complexity, mainly due to severe shadows cast by the wild vegetation and trees, makes it challenging to extract rural roads based on processing aerial or satellite images, leading to het...
An integrated decision support system for improving wildfire suppression manage...
Lourenço, Miguel; Oliveira, Luis; Oliveira, João; Mora, André; Santos, Rui; Oliveira, HenriqueWildfires are expected to increase in number, extent, and severity due to climate change.Hence, it is ever more important to integrate technological developments and scientific knowledgeinto fire management aiming at protecting lives, infrastructure, and the environment. In this paper,a decision support system (DSS) adapted to the Portuguese context and based on multi-sensortechnologies and geographic informati...
Robotic Partial Nephrectomy of Endophytic Tumor: Technique and Result
Graça, Bruno; Formoso, Rui; Lourenço, Miguel; Maes, KrisRobotic surgery allows complex oncological renal surgery with at least equivalent safety and outcomes profiles when comparing to open and laparoscopic approach. We describe a robotic partial nephrectomy of an endophytic tumor with intraoperative ultrasound support and 10th month follow-up outcome.; A cirurgia robótica permite a realização de cirurgia renal complexa, nomeadamente oncológica, com segurança e resu...
Horizontal and Vertical Handheld Pointing Devices Comparison for Increasing Hum...
Lourenço, Miguel; Pitarma, Rui; Coelho, DenisIn addition to postural and biomechanical aspects related to usage of handheld pointing devices it is also important to perform usability assessment. The paper reports on an experimental study comparing two computer pointing devices, a standard horizontal PC mouse and a vertical device (for neutral pronation of the forearm), both commercially available. The standardized tasks implemented by software and perform...
Improving occupational health by modelling indoor pollutant distribution
Pitarma, Rui; Lourenço, Miguel; Ramos, JoaoPurpose Indoor environments are characterized by several pollutant sources. Some of these can be sufficiently characterized through the prediction of the airflow and pollutant distribution patterns. The purpose of this study was to simulate, analyze and compare different locations of known pollutant source inside a ventilated room. Design/methodology/approach Computational fluid dynamics modelling approach was ...
