Multi-objective optimization for reducing the auxiliary electric energy peak in low cost solar domestic hot-water heating systems in Brazil
(Elsevier, 2018)
Domestic water heating in Brazil is commonly done by electric showerheads, characterized by a large installed capacity and a low load factor. In that regard, consumers and utility companies present opposite interests, the ...
Reliability of peak O-2 uptake and O-2 uptake kinetics in step exercise tests in healthy subjects
(Elsevier B.V., 2015-02-01)
To date little is known about the reliability of peak oxygen consumption (VO2pEAK) in incremental metronome paced step tests (1ST) and the reliability of on-kinetics VO2 has never been studied. We aimed to study the ...
Implantação e análise de um sistema fotovoltaico conectado à rede de 10,72 kWp com sistema de armazenamento de energia na UTFPR
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Sistemas de EnergiaUTFPR, 2021-08-31)
With the growing penetration of intermittent renewable energy sources in the Brazilian energy mix, like the photovoltaic, which in 2021 has exceeded the mark of 11GW of installed capacity, the interest for energy storage ...
Desenvolvimento de receptor de wake-up de tempo discreto para CMOS 180nm
(Universidade do Vale do Rio dos Sinos, 2022-03-25)
This work proposes a discrete-time (DT) wake-up receiver (WUR) as a solution to reduce the power consumption of Internet of Things (IoT) devices. The core of the proposed circuit is the discrete-time mixer, formed by a ...
