Aspectos estruturais de compostos de Mn(II) com a lausona ou lapachol
(Universidade Federal de São Carlos, 2023-02-27)
Neste trabalho foram sintetizados complexos de manganês(II) contendo ligantes N,N-heterocíclicos (1,10-fenantrolina e 2,2’-bipiridina) e as naftoquinonas 2-hidroxi-3-(3-metil-2-butenil)-1,4-naftoquinona (lapachol) e ...
Análise da influência da texturização superficial em mancais hidrodinâmicos radiais
(Universidade Federal de São Carlos, 2023-02-23)
The use of textured surfaces can be observed in several applications where an improvement of a certain characteristic of the product or process is sought, with the aim of changing the conditions of friction, wear, and ...
Inferência Bayesiana para modelos de volatilidade estocástica baseados em mistura de escala da distribuição normal assimétrica
(Universidade Federal de São Carlos, 2023-02-28)
This dissertation aims to evaluate and compare the performance of the No-U-Turn Sampler
(NUTS) algorithm, implemented in the Stan software, in estimating the parameters of stochastic
volatility models with leverage based ...
Resistência ao cisalhamento de lajes alveolares contínuas em pavimentos a partir do mecanismo de tração diagonal
(Universidade Federal de São Carlos, 2023-04-27)
The use of continuous hollow core slabs with structural topping floors has increased in the past few years in the civil construction. By reason of this use, different types of loads can occur on the hollow core slabs units, ...

(Universidade Federal de São Carlos, 2021-08-27)
In the last years, the carbon has attracted scientific and technological interest due to its different allotropic forms, as graphite, graphene, fullerene, and carbon nanotubes, which present unique and promising properties. ...
Using VAE for incomplete educational data
(Universidade Federal de São Carlos, 23-03-13)
In Psychometrics, especially in educational assessments, incomplete databases are common.
An individual may leave items unanswered in an assessment due to lack of time, forgetting
the content involved, nervousness, or ...
Bayesian estimation of dynamic mixture models by wavelets
(Universidade Federal de São Carlos, 2023-04-20)
Gaussian mixture models are used successfully in various statistical learning applications. The good results provided by these models encourage several generalizations of them. Among possible adaptations, one can assume a ...
Teoremas limite para variáveis aleatórias de Bernoulli dependentes
(Universidade Federal de São Carlos, 2023-03-22)
In this work, we consider a sequence of correlated Bernoulli variables whose probability of success for the current trial depends conditionally on previous trials. This conditional probability is given as a linear function ...
Análise comparativa do desempenho mecânico de tipologias de treliças planas de madeira para classes de resistência distintas via algoritmo de otimização
(Universidade Federal de São Carlos, 2023-04-27)
Wood is a viable choice for building systems, given its mechanical properties suitable for structural applications. In addition, wood is a renewable source, making it even more attractive for use in various applications ...
Aplicação de redes neurais para classificação de microinclusões de sulfeto de manganês em aços
(Universidade Federal de São Carlos, 2023-02-24)
The factors that measure the influence of inclusions on steel properties are the distribution, morphology and size of inclusions. The standard used as a reference is ASTM E45, which explains the sample scanning method in ...
