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 ...
Algoritimo de detecção de retinopatia diabética baseado em aprendizado de máquina
(Universidade Federal de São Carlos, 2023-04-06)
In this study, the application of neural network and machine learning techniques was explored in order to identify the presence of lesions related to diabetic retinopathy (DR) in fundus images. DR is a frequent complication ...
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 ...
Discussão sob as perspectivas técnica, econômica e ambiental do uso de concentradores baseados em lentes de Fresnel em sistemas de geração fotovoltaica
(Universidade Federal de São Carlos, 2024-02-08)
With the expansion and popularization of photovoltaic energy generation systems, con- sumers classified in group A, whether captive or free, meet a significant portion of their demands. However, depending on the size of ...
Análise de sentimentos no domínio do e-commerce utilizando modelos de linguagem
