Developing a new simulation and visualization platform for researching aspects ...
Amaro, C.; Saraiva, T.; Duarte, D.; Vieira, Pedro; Queluz, Maria Paula; Rodrigues, A.Nowadays, mobile networks represent one of the most innovative and challenging technological and research-oriented fields of work. The growth on user subscriptions and the advances introduced by Artificial Intelligence (AI) and Internet of Things (IoT), greatly enhanced the complexity and potential of communication networks. The increase on variety of devices and exchanged mobile data traffic resulted in demand...
Impact of gestational diabetes and treatment on the metabolome of non-invasive ...
Duarte, D.; Pita, C.; Negrão, F.; Carreira, I.; Pereira, J. L.; Costa, A. L.; Almeida, M. do Céu; Gil, A. M.Introduction: Gestational diabetes mellitus may determine pregnancy outcome and impact on offspring health. Knowledge on associated metabolic mechanisms may provide new biomarkers to support diagnosis and treatment protocols. Untargeted metabolomics is effective in biomarker search and, thus, of significant value in this context. Aims: This work aims to find urinary/salivary metabolic biomarkers of the disease ...
Effects of geospatial data sources on the identification and characterization o...
Fonte, C. C.; Patriarca, J.; Duarte, D.The work presented in this paper compares the burnt areas in continental Portugal in 2017 and 2018 mapped by three initiatives, namely the Portuguese Institute of Nature and Forests Conservation (ICNF), the Corine Land Cover (CLC) inventory of the Copernicus programme and the European Forest Fire Information System (EFFIS). Then, the Land Use Land Cover (LULC) classes affected by the 2017 burnt areas mapped by ...
Development and validation of a repairing procedure for PV modules on-site
Fialho, L.; Duarte, D.; Pires, C.; Horta, P.Os módulos fotovoltaicos podem desenvolver alguns defeitos durante a operação contínua ao longo do seu tempo de vida. Alguns desses defeitos não apresentam um risco acrescido inicial, mas podem evoluir gradualmente para uma falha perigosa, refletindo-se numa redução na produção de eletricidade, paragens imprevistas e constituir um risco pessoal ou para a instalação. Estes defeitos podem ser reparados na sua fas...
Addressing the class imbalance problem in the automatic image classification of...
Duarte, D.; Andriolo, U.; Gonçalves, G.Unmanned Aerial Systems (UAS) has been recently used for mapping marine litter on beach-dune environment. Machine learning algorithms have been applied on UAS-derived images and orthophotos for automated marine litter items detection. As sand and vegetation are much predominant on the orthophoto, marine litter items constitute a small set of data, thus a class much less represented on the image scene. This comm...
Infrastructure degradation and post-disaster damage detection using anomaly det...
Tilon, S. M.; Nex, F.; Duarte, D.; Kerle, N.; Vosselman, G.Degradation and damage detection provides essential information to maintenance workers in routine monitoring and to first responders in post-disaster scenarios. Despite advance in Earth Observation (EO), image analysis and deep learning techniques, the quality and quantity of training data for deep learning is still limited. As a result, no robust method has been found yet that can transfer and generalize well ...

Carbidopa Alters Tryptophan Metabolism in Breast Cancer and Melanoma Cells Lead...
Duarte, D.; Amaro, F.; Silva, I.; Silva, D.; Fresco, P.; Oliveira, José Carlos; REGUENGO, HENRIQUE; Gonçalves, J.; Vale, N.Carbidopa is used for the treatment of Parkinson's disease (PD) as an inhibitor of DOPA decarboxylase, and PD patients taking carbidopa have a lower incidence of various tumors, except for breast cancer and melanoma. Recently, it was shown that carbidopa inhibits tryptophan-2,3-dioxygenase (TDO) and kynureninase enzymes. In the present study, the effect of carbidopa on the viability and metabolic profile of bre...
Experimental testing and CFD modelling for prototype design of innovative Artif...
Maslov, Dmytro; Johnson, J.; Pereira, E. N. B.; Duarte, D.; Miranda, Tiago F. S.; Lima, M. M. C. L.; Cruz, Fábio Quintas; Valente, Isabel B.This research aims to provide insight on the experimental results obtained induring hydraulic flume channel testing of a multifunctional artificial reef (MFAR) prototype employing various turbulence models and discretization schemes for Computational Fluid Dynamics (CFD) numerical simulations. The recently developed Multifunctional Artificial Reef is believed to be an effective tool to support marine ecosystem ...
Experimental characterization of the scour of innovative artificial reef protot...
Cruz, F.; Pereira, E. N. B.; Lima, M. M. C. L.; Johnson, J.; Duarte, D.; Valente, Isabel B.; Miranda, Tiago F. S.; Maslov, Dmytro; Pinheiro, M.This paper describes an experimental study of an innovative Multifunctional Artificial Reef geometry, as part of the decision framework for its planning, design, construction, and installation. The aim is to experimentally assess the scour phenomenon and the hydrodynamic behaviour of a small-scale multifunctional artificial reef prototype (PMFAR) in a noncohesive bed of sediment. Hydraulic flume tests and a pho...
