Construção de reator de plasma frio para aplicações de filmes finos
(Universidade Federal de São Carlos, 2022-03-04)
It is about the construction of a sputtering system, through the use of a cold plasma reactor, for the deposition of metallic thin films. Basically, this system works by ejecting atoms from a material (target) by the ...
Sistema óptico de projeção a laser para análise da superfície das pregas vocais em imagens laringoscópicas
(Universidade Federal de São Carlos, 2021-09-17)
When understanding the acoustic production of the human voice and its dysphonia, factors such as characteristics and dimensions of the vocal folds are relevant. Previous studies show that images of the glottic surface, ...
Análise da eficiência energética em edificações usando os métodos RTQ-C e INI-C
(Universidade Federal de São Carlos, 2022-02-23)
The urban development of the last decades has caused a considerable increase in the energy consumption of buildings, which increased the interest in improving the energy efficiency of buildings justifying the use of the ...
Proposta da utilização de uma fibra de núcleo oco anti-ressonante para detecção simultânea de metano, monóxido de carbono e monóxido de nitrogênio
(Universidade Federal de São Carlos, 2022-03-11)
Hollow-Core Anti-Resonant Optical Fibers (AR-HCF) is a novel hollow-core fiber with a low refractive index in the core and a high refractive index in the cladding. Unlike conventional solid-core optical fibers, where light ...

(Universidade Federal de São Carlos, 2022-07-22)
Nowadays, technological evolution has allowed advances in several areas, especially in healthcare. Digital transformation in health has brought benefits to both professionals and patients. What was possible to do only with ...
Aproximação funcional dos limites de estabilidade/segurança de tensão por redes neurais artificiais com seleção de atributos em problemas de fluxo de potência ótimo
(Universidade Federal de São Carlos, 2022-01-10)
The object of this research is the proposal of a model for Voltage-Stability/Security on strained Optimal Power Flow (VSSC-OPF) problems applied to mid-term energy procurement auction systems in electricity markets. In the ...
Método automático de calibração de IMU baseado no filtro de Kalman
(Universidade Federal de São Carlos, 2021-12-17)
IMUs are widely used in applications that require position and attitude measurements. And with the production of low-cost IMUs, it has been possible to expand this
use beyond military and high-cost applications, reaching ...
Planejamento de véspera da operação horária de microrredes com geração fotovoltaica distribuída integrada por inversores inteligentes via programação não linear inteira mista
(Universidade Federal de São Carlos, 2021-12-16)
The penetration of photovoltaic distributed generation in distribution networks has become a reality; however, it still imposes challenges to be overcome, such as the operation of these networks with minimal deviations in ...
High integrated battery monitoring system with active balancing up to ±10A
(Universidade Federal de São Carlos, 2022-02-22)
This master's thesis describes the development, construction, and setup of a flexible and modular, highly integrated battery monitoring system. The electronic unit uses an active balancing process with currents up to ±10A ...
Estimador seletivo do conteúdo harmônico de tensão e corrente baseado em rede neural profunda
(Universidade Federal de São Carlos, 2022-04-27)
A common issue when non-linear loads are present in electric power distribution systems is voltage and/or current harmonic distortion. This power quality (PQ) problem can be mitigated, but first the harmonic components ...
