Tuna, Patrícia; Tuna, Patrícia; Almeida, Sofia; Ferreira, Ana Sara; Santos Coelho, Francisco; Couto, Pedro; Teves Reis, Bárbara; Gonçalves, AnaIntrodução: As patologias de saúde mental estão entre os problemas de saúde mais comuns em todo o mundo, sendo uma causa importante de morbilidade e isolamento social. Este trabalho teve como objetivo implementar um projeto de intervenção com pessoas que sofrem de ansiedade e/ou depressão, com o intuito de melhorar os seus índices de depressão e ansiedade. Métodos: Pacientes de uma Unidade de Saúde Familiar por...
A new hotel classification model combining guest reviews with official hotel cl...
Messias, Ana; Rosa, Gilberto; Couto, Pedro; Rodrigues, Vítor; Silva, Luís M.; Marques, JorgeThis paper explores the potential of combining online guest reviews with hotel classification systems, focusing on the feasibility of incorporating such reviews at the star-classification level. Leveraging machine learning techniques on a database of Portuguese hotels and their corresponding ratings on Booking.com, this study reveals a weak association between official hotel star categories and mean review scor...
Combining UAV-Based Multispectral and Thermal Infrared Data with Regression Mod...
Guimarães, Nathalie; Sousa, Joaquim J.; Couto, Pedro; Bento, Albino; Pádua, LuísUnderstanding and accurately predicting stomatal conductance in almond orchards is critical for effective water-management strategies, especially under challenging climatic conditions. In this study, machine-learning (ML) regression models trained on multispectral (MSP) and thermal infrared (TIR) data acquired from unmanned aerial vehicles (UAVs) are used to address this challenge. Through an analysis of spectr...
Comparative Evaluation of Remote Sensing Platforms for Almond Yield Prediction
Guimarães, Nathalie; Fraga, Helder; Sousa, Joaquim J.; Pádua, Luís; Bento, Albino; Couto, PedroAlmonds are becoming a central element in the gastronomic and food industry worldwide. Over the last few years, almond production has increased globally. Portugal has become the third most important producer in Europe, where this increasing trend is particularly evident. However, the susceptibility of almond trees to changing climatic conditions presents substantial risks, encompassing yield reduction and quali...
Remote Sensing Applications in Almond Orchards: A Comprehensive Systematic Revi...
Guimarães, Nathalie; Sousa, Joaquim J.; Pádua, Luís; Bento, Albino; Couto, PedroAlmond cultivation is of great socio-economic importance worldwide. With the demand for almonds steadily increasing due to their nutritional value and versatility, optimizing the management of almond orchards becomes crucial to promote sustainable agriculture and ensure food security. The present systematic literature review, conducted according to the PRISMA protocol, is devoted to the applications of remote s...
Monitorização da amendoeira através de dados espacio-temporais adquiridos por v...
Guimarães, Nathalie; Pádua, Luís; Sousa, Joaquim J.; Bento, Albino; Couto, PedroA amendoeira (Prunus dulcis (Mill.) D. A. Webb) é uma cultura em expansão em várias regiões do mundo. Em Portugal, esta expansão materializou-se com o aparecimento de novas plantações no País, a intensificação do sistema produtivo e o aumento da área de regadio. Para atender à crescente procura de amêndoas, é essencial investir em tecnologias agrícolas, com vista a aumentar os níveis de produção e realizar a mo...
Almond cultivar identification using machine learning classifiers applied to UA...
Guimaraes, Nathalie; Padua, Luis; Sousa, Joaquim J.; Bento, Albino; Couto, PedroIn Portugal, almonds are a very important crop, due to their nutritional properties. In the northeastern part of the country, the almond sector has endured over time, with strong cultural traditions and key economic significance. In these areas, several cultivars are used. In effect, the presence of various almond cultivars implies differentiated management in irrigation, disease control, pruning system, and ha...
Identification of aphids using machine learning classifiers on UAV-based multis...
Guimarães, Nathalie; Pádua, Luís; Sousa, Joaquim J.; Bento, Albino; Couto, PedroAlmond trees in Portugal are susceptible to aphid infestation, which can result in reduced fruit production. To effectively tackle this issue, the combination of remote sensing (RS) data and machine learning (ML) classifiers can be used to accurately detect the presence of aphids. This study focuses in the implementation of ML classifiers and RS data analysis to identify aphids on almond trees, using high-resol...
Physicians' perceptions of psychosocial factors and coping strategies in their ...
Messias, Ana; Estrela, Marta; Couto, Pedro; Sá-Couto, Pedro; Ramos, MarcoBackground/Objective: Physicians play a crucial role in healthcare systems but face negative impacts from a challenging work environment, leading to burnout. Burnout has negative effects on physician health and patient care. Understanding psychosocial aspects of work and coping strategies used by physicians is essential. Validated tools, including COPSOQ-II, BriefCOPE, and WAI scales, can provide insight into t...
