Music therapy interventions for adults with depression admitted to the oncology...
Gomes, Aramid; Silva, Bruna; da Silva Lírio, Carlota; Silva, Débora; Pereira, Jessica; Costa, Nuno; Mota, LilianaIntroduction: Cancer was responsible for almost 10 million deaths in 2020, making it one of the leading causes of mortality worldwide. In addition to the physical impacts, chronic illnesses such as cancer can trigger psychological symptoms such as anxiety and depression, the latter being more prevalent in people with chronic illnesses than in the healthy population. Objective: To map music therapy interventions...
A Benchmark of Automated Multivariate Time Series Forecasting Tools for Smart C...
Pereira, Pedro José; Costa, Nuno; Mestre, Pedro; Cortez, PauloMost Smart Cities data come from multiple related sensors. Within this context, multivariate Automated Time Series Forecasting (AutoTSF) tools are valuable for providing predictive analytics for citizens and city rulers. In this paper, we benchmark seven multivariate open-source AutoTSF tools (AutoARIMAX, AutoGluon, FlaML, AutoTS, MFEDOT and HyperTS) and one univariate AutoTSF tool (FEDOT), measuring both their...
Enhanced thermal management strategies for SiC MOSFETs in EV fast charging syst...
Awais, Muhammad; Amin, Saghir; Brit, Francisco P.; Afonso, João L.; Costa, Nuno; Monteiro, Vítor Duarte FernandesHigh-power density fast chargers for electric vehicles (EV) face significant thermal stress and require effective thermal management to ensure highly efficient, and long-lived operation, as well as to address reliability issues. Silicon carbide (SiC) MOSFETs are used in such EV fast chargers because of their efficient power conversion and inherent thermal stability during fast charging. However, addressing cruc...
Impact of fixed vs. variable DC-Link voltages on maximizing efficiency of EVs f...
Amin, Saghir; Awais, Muhammad; Rocha, Joao; Afonso, João L.; Costa, Nuno; Monteiro, Vítor Duarte FernandesIn this study, the effect of the DC-link voltage on the efficiency of a two-stage converter system used in an electric vehicle (EV) fast-charging systems is presented. The rectification is performed in the first stage by means of an AC/DC three-phase three-level T-type converter (3P3L-T-type), and the second stage consists of a two-stage DC/DC converter that charges the EV battery. A comprehensive analysis of t...
Enhanced and uniform thermal management system based on an integrated vapor cha...
Awais, Muhammad; Amin, Saghir; Brito, Francisco P.; Afonso, João L.; Costa, Nuno; Monteiro, Vítor Duarte FernandesThe need for high-performance thermal management systems is increasing as the power densities of SiCbased converters in electric vehicle (EV) chargers tend to also increase. This study explores the integration of a vapor chamber into heat sink designs, utilizing the evaporation condensation cycle of a working fluid to enhance heat dissipation and reduce thermal resistance. A detailed comparison was conducted, s...
Dual resonant tank single-stage LLC converter with variable DC-Link voltage and...
Saghir Amin,; Awais, Muhammad; Loureiro, Pedro; Afonso, João L.; Costa, Nuno; Monteiro, Vítor Duarte FernandesThis paper introduces a single-stage LLC converter architecture featuring a dual resonant tank with a single bridge and two separate rectifiers operating in a series-parallel configuration. The proposed dual resonant tank single-stage LLC converter (2RTSS-LLC) design addresses the challenges of operating with variable input DC-link voltage, while achieving wide output voltage range, making it specifically suite...
Nurses' Interventions in Minimizing Adult Patient Vulnerability During Extracor...
Costa, Nuno; Henriques, Helga Rafael; Durão, CândidaIntroduction: People during extracorporeal membrane oxygenation (ECMO) as a bridge to lung transplantation find themselves in a high degree of physical and psychological vulnerability, which could cause additional problems for their health status. Therefore, this review aims to identify the interventions that shape critical nursing care to minimize patient vulnerability during ECMO as a bridge to lung transplan...
Impacto Físico e Psicológico na Vida de um Cuidador Informal
Alves, Inês; Pinto, Jorge; Rego, Maria Inês; Marcos, Miriam; Costa, Nuno; Conde, Samuel; Ribeiro, Andrea MiguelIntrodução: Os cuidadores informais desempenham um papel crucial na prestação de cuidados a indivíduos com doenças crónicas ou incapacidades. Esta tarefa pode gerar uma sobrecarga física e psicológica significativa, impactando negativamente a qualidade de vida dos cuidadores.
