Correlações intrínsecas em sistemas tipo-Dirac confinados por um campo magnético constante
(Universidade Federal de São Carlos, 2024-07-04)
The Weyl-Wigner formalism in phase space is investigated in the context of Dirac spinors as qubits correlated by continuous degrees of freedom. The extension to relativistic equations connects quantum mechanical phenomena ...
Considerações e possíveis soluções para o problema da estimação do mínimo populacional com aplicações em dados de terremotos
(Universidade Federal de São Carlos, 2024-04-29)
A myriad of physical, biological and other phenomena are better modeled with semi-infinite distribution families, in which case not knowing the populational minimum becomes a hassle when performing parametric inference. ...
Modelagem numérica do perfil térmico e do escoamento de material termoplástico por extrusão em um cabeçote customizado para manufatura aditiva
(Universidade Federal de São Carlos, 2024-04-10)
This work presents a procedure for modeling and numerical analysis of the flow of a thermoplastic fluid with pseudoplastic behavior applied to a custom miniature vertical head based on twin-screw extrusion for additive ...

(Universidade Federal de São Carlos, 2023-05-29)
It is well known that several researches related to the development of renewable and alternative energy sources are currently in course. However, with the continuous increase on energy demand around the world, it is still ...
Melhorando a tomada de decisões na construção: Modelagem não paramétrica de atrasos induzidos pelo clima
(Universidade Federal de São Carlos, 2024-05-23)
Effective construction project management faces significant challenges due to frequent delays, many of which are influenced by climatic variables. Anticipating these delays is crucial, and although various methods based ...
The coopetitive effect in supply chains: exploring the relationship between multiple supply chains from the focal agent perspective
(Universidade Federal de São Carlos, 2024-04-10)
This thesis explores the possibility of a form of interaction between supply chains known as coopetition, which combines cooperation and competition. The main objective is to investigate coopetition among multiple supply ...
Síntese de nanopartículas de CuO e aplicações catalíticas
(Universidade Federal de São Carlos, 2024-03-28)
Global population growth, reaching 8 billion people in November 2022, will continue to impose significant pressures on industrial production, agriculture, urban mobility, and energy demand. Coupled with the depletion of ...
Fotodegradação de contaminantes emergentes por catalisadores à base de PHI (Poli Heptazina Imida)
(Universidade Federal de São Carlos, 2023-07-17)
The remediation of pollutants promoted by systems that are cheap and viable remains an important challenge in the field of catalysis. Carbon nitrides applied in photocatalytic systems are a promising class of materials for ...
