Ensaios destrutivos e não destrutivos em cordão de solda a gás inerte com eletrodo de tungstênio na fabricação de tanques de aquecedor solar com espessura de chapa reduzida
(Universidade Federal de São Carlos, 2023-08-01)
TIG welding processes are widely used to join metallic materials of different thicknesses, such as stainless steel. These are processes used in different segments of the industry, highlighting in the metallurgical area the ...
Ações de Z2k com o conjunto de pontos fixos conexo e a propriedade CP
(Universidade Federal de São Carlos, 2021-10-27)
It is well known that if $\phi:G \times M^m \rightarrow M^m$ is a smooth action of a compact Lie group on a closed smooth manifold, then its fixed point set $F_{\phi} = \bigcup\limits_{i=0}^{n}F^{i}$ is a disjoint union ...
Correlação entre achados ecocardiográficos de função ventricular esquerda e aptidão aeróbica em indivíduos diabéticos
(Universidade Federal de São Carlos, 2021-12-17)
Background: Type 2 diabetes mellitus is a chronic disease capable of causing micro and macrovascular complications, in addition to abnormalities in cardiac function that directly impact aerobic fitness. Studies show that ...
Caracterização do óxido formado na superfície da junta M5TM/Zircaloy- 4 soldada por resistência e pressão após testes de corrosão em autoclave a 360°C
(Universidade Federal de São Carlos, 2024-04-10)
The nuclear fuel cycle involves uranium mining and chemistry, fuel manufacturing, fuel element operation in reactors, and post-irradiation treatment. The casing tubes are produced with zirconium alloys, as they have a low ...

(Universidade Federal de São Carlos, 2024-02-16)
This research arose when we sought to understand what level of development of Algebraic Thinking (AT) that students in the 10th – grade, High School, who opted for a training itinerary in which mathematics is not present ...
Poliedros de Newton e invariantes de singularidades determinantais
(Universidade Federal de São Carlos, 2024-01-31)
In this work, we study invariants of determinantal singularities, by analysing the Newton polyhedra which arise from the entries of a given matrix. The main contribution of this work is providing sufficient conditions, ...
Inferência Bayesiana em modelos de volatilidade estocástica na média utilizando o método de Monte Carlo Hamiltoniano em variedade Riemanniana
(Universidade Federal de São Carlos, 2024-02-21)
This paper considers the stochastic volatility in mean model, where the conditional distribution of the data belongs to the mixed-scale normal family for modeling financial time series. This model class is more robust in ...
