Transformações alotrópicas de carbono induzidas por irradiação com feixe de elétrons
(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 ...
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 ...
Perturbações unitárias multiplicativas
(Universidade Federal de São Carlos, 2023-05-24)
For the self-adjoint operator H, the perturbation H+A, with A also a self-adjoint operator, there is a long list of results regarding the spectrum of this perturbation. We study the spectrum of a multiplicative perturbation ...
Relaxação de spin em nanoestruturas semicondutoras 0 e 2D
(Universidade Federal de São Carlos, 2023-03-01)
This thesis contains a compilation of the work developed and is divided into
three main parts. The first part describes the homogeneous and inhomogeneous
decoherence mechanisms of excitons in GaAs/AlGaAs quantum wells. ...
Metodologias sintéticas envolvendo reações fotoquímicas e eletroquímicas em condições de batelada e fluxo contínuo
(Universidade Federal de São Carlos, 2023-04-26)
SYNTHETIC METHODOLOGIES INVOLVING PHOTOCHEMICAL AND ELECTROCHEMICAL REACTIONS IN BOTH BATCH AND CONTINUOUS FLOW CONDITIONS. Initially (Chapter 1), general aspects of the studied reactions were presented and in the chapter ...
Estudo sobre a tensão de aderência em concretos autoadensáveis com baixo consumo de cimento reforçado com fibras de aço
(Universidade Federal de São Carlos, 2023-02-17)
This research studied the behavior of Self-Compacting Concrete with Low Cement
Consumption (SCCLCC) with steel fibers reinforced in their properties in both states fresh and
hardened, related to mechanical properties ...
Juntas de aço inoxidável super duplex UNS S32760 soldadas por fricção e mistura mecânica (FSW): microestrutura e comportamento de corrosão eletroquímica
(Universidade Federal de São Carlos, 2022-04-29)
In this study, the corrosion resistance of the face and root surface of an AISD UNS S32760 friction stir welded (FSW) joint using optimized parameters was investigated. Microstructural changes were evaluated by MO, SEM and ...
Framework para investigação de mapeamentos de aplicações em arquiteturas manycore
(Universidade Federal de São Carlos, 2022-12-07)
This thesis proposes an implementation of a framework for mapping graphs onto manycore architectures with multi-objective metrics optimization. The aim is to propose a new approach in relation to the works found in the ...
Paredes de contraventamento de alvenaria grauteadas e armadas nas extremidades: comportamento, capacidade, desempenho sísmico e modelos simplificados de projeto
(Universidade Federal de São Carlos, 2023-03-09)
Partially grouted masonry structures are widely used worldwide, preferably in regions with low and mid-intensity wind and seismic loads. Thus, this thesis focuses on partially grouted masonry walls (PGMW), especially those ...
