Decomposição da variância para o modelo de regressão destrutivo Waring de longa duração
(Universidade Federal de São Carlos, 2020-04-17)
The goal of this work is to formulate a two-stage regression long-term model, whose destructive mechanism of the competitive risk factors is flexible for measuring the impact on the survival function or cure rate of ...
Solubilização biológica de rocha potássica para aplicação como biofertilizante
(Universidade Federal de São Carlos, 2020-02-18)
Potassium (K) plays an important role in several biochemical and physiological processes in plants, but the low concentrations of soluble K in the soil make it necessary to use chemical fertilizers in order to supply the ...
Um estudo sobre sistemas baseados em regras Fuzzy
(Universidade Federal de São Carlos, 2020-02-28)
The practice of medicine is an analytical and uninterrupted decision-making process in
which the variables involved are often subjective (i.e. not measurable) so Fuzzy Logic is
a very participative resource in the ...
Elaboração e aplicação de ferramenta para avaliação da gestão e gerenciamento de resíduos sólidos urbanos para municípios brasileiros. Estudo de caso: municípios de Araraquara (SP) e São Carlos (SP)
(Universidade Federal de São Carlos, 2020-03-27)
Solid waste generation is inherent to the urban and rural environment. However, the new consumption patterns and the industrial development have changed the waste quantity and composition. With the enactment of Law Nº. ...
Método de reconstrução tomográfica de amostras agrícolas com o emprego de técnicas big data
(Universidade Federal de São Carlos, 2020-01-31)
A new method of high resolution tomographic reconstruction of agricultural samples is presented, which uses the spectral density of X-ray tomographic projections as a criterion to minimize processing time and obtain good ...
Formulações semiclássicas da mecânica quântica: uma análise do oscilador singular por meio do formalismo de Weyl-Wigner e trajetórias quânticas
(Universidade Federal de São Carlos, 2020-02-10)
The usual quantum mechanics formalism does not address relevant points of the semiclassical limit. In this work two theoretical approaches will be considered: Bohmian mechanics and the Weyl-Wigner formulation. The singular ...
Estudo sobre a substituição de armadura metálica por barras de GFRP em vigas de concreto armadas à flexão quando submetidas ao ataque acelerado de íons cloreto
(Universidade Federal de São Carlos, 2020-02-28)
The use of reinforced concrete structures with steel bars is recurrent in the construction industry in Brazil. However, alternative materials are studied due to the existence of problems related to the use of this traditional ...
Atratores pullback para uma equação de difusão não autônoma com retardo
(Universidade Federal de São Carlos, 2020-03-12)
Our goal in this work is to study a nonautonomous parabolic differential equation. We are going to show some results about existence of pullback attractors for this type of problem and for the equation without the delay.
Sensores nanoestruturados compostos por nanofibras de dióxido de titânio modificadas com polímeros condutores visando monitoramento de compostos orgânicos voláteis
(Universidade Federal de São Carlos, 2020-03-18)
The growth of urbanization and anthropogenic activities have been increasing the emission of polluting gases in the atmosphere. Considering the high toxicity of some of these gases, it becomes necessary to develop new ...
Grafeno multicamadas através de grafos quânticos periódicos: cones de Dirac
(Universidade Federal de São Carlos, 2020-03-06)
We study the spectral characterization and Dirac cones, always through periodic quantum graphs, in three situations. Firstly, we model bidimensional honeycomb materials, for instance, Graphene and Boron Nitride. We consider ...
