Um estudo sobre consumo de energia em aplicações JavaScript: Identificação dos custos energéticos para a etapa de integração continua
(Universidade Federal de São Carlos, 2023-03-22)
Given the climate context that the world finds itself in, controlling the energy consumption that humans perform on a daily basis is indispensable for the well-being of the planet and sustainability. For software this is ...
Análise de um amplificador de áudio padrão
(Universidade Federal de São Carlos, 2023-04-14)
This work analyzes and assembles the 50W "Blameless" audio amplifier designed by Douglas Self in his book. The three stages of the amplifier, the feedback loop, and the mechanisms used to minimize distortion were studied. ...
Classificação de imagens de satélite com redes neurais convolucionais
(Universidade Federal de São Carlos, 2023-04-06)
Satellite images are used in several areas, such as agribusiness, urban planning, environmental monitoring, among others. These images have a large and complex amount of data and the application of Machine Learning techniques ...
Modelando moléculas fotônicas usando a teoria dos grafos
(Universidade Federal de São Carlos, 2023-04-03)
This work aims to demonstrate a practical way to model Photonic Molecules (PMs), using tools often used in control theory. It is shown here how it is possible to model systems composed of coupled electromagnetic resonators ...
Novas arquiteturas fotônicas para redução da dependência do fator de qualidade e fator de extinção à erros de nanofabricação em cavidades ópticas
(Universidade Federal de São Carlos, 2023-04-04)
In this work, experimental data from a device fabricated in a Foundry was used to demonstrate a reduction in the dependence of the quality factor and the minimum power transmitted to nanofabrication errors. To prove this, ...
Desenvolvimento de um sistema para economia de combustível com rede neural artificial
(Universidade Federal de São Carlos, 2023-04-06)
This article aims to develop a data acquisition board to identify the uphill and downhill stretches of a vehicle through an LSTM (Long Short Term Memory) artificial neural network, and to estimate the reduction in fuel ...
Aplicação de redes neurais para previsão de demanda de energia elétrica
(Universidade Federal de São Carlos, 2023-04-05)
In the early 2000s, the Brazilian electrical system was less developed than it is today and depended much more on hydroelectric generation, as 80% came from it. A study conducted by the Ministry of Mines and Energy revealed ...
Projeto, implementação e testes de um amplificador de áudio de alta fidelidade para fones de ouvido
(Universidade Federal de São Carlos, 2023-09-01)
In this monograph, a high fidelity audio amplifier with tone control for headphones was developed. Circuits are built on printed circuit boards using discrete components. Topologies were initially determined to be simulated ...
