Indicadores de desempenho como instrumento de gestão de lodo de estações de tratamento de esgoto
(Universidade Federal de São Carlos, 2023-04-27)
The improvement and efficiency of sanitary sewage systems depend on management from an integrated perspective. An important stage that composes the sewage systems is the management of the solid waste generated, however, ...
Platforms based on semiconductors for application in quantum computing
(Universidade Federal de São Carlos, 2023-06-02)
This thesis is composed of three parts. In the first part, a study of transport in semiconductor nanowires is carried out, in which the multichannel scattering occurs in a certain finite region, providing a reentrance in ...
Métodos Bayesianos para seleção de modelos de mistura de distribuições normais e t de Student assimétricas
(Universidade Federal de São Carlos, 2023-06-28)
In this work, we consider mixture models whose components of the mixture are modeled by the skew normal and skew t distributions. For the estimation of these skew mixtures models, we used a Bayesian approach, via Markov ...
Eletrodeposição de filmes do tipo Ni-X (X=P, Cu ou Cu-P) a partir de banhos contendo aspartato
(Universidade Federal de São Carlos, 2022-11-25)
In the present work, aspects related to the electrodeposition of Ni-based metal films - either pure metal or Ni-P, Ni-Cu, and Ni-Cu-P alloys - from baths containing aspartate complexes as electroactive species and hypophosphite ...
Avaliação de aditivos poliméricos e cerâmicos para a otimização microestrutural de refratários semi-isolantes
(Universidade Federal de São Carlos, 2023-07-21)
Macroporous insulating refractories have been extensively investigated due to their low thermal conductivity, low density, and non-toxicity compared to fibrous ceramic insulators. However, there are still challenges in ...
People s awareness of circular economy: scale development and relationship with social influence, psychological barriers, and favourable evaluation of sustainable development
(Universidade Federal de São Carlos, 2023-04-13)
Circular Economy (CE) encompasses strategies that aim to decouple economic activity from finite resource consumption and eliminate waste from the system as a matter of principle. Supported by a transition to renewable ...
Teorema da esfera suave via fluxo de Ricci
(Universidade Federal de São Carlos, 2023-08-04)
The goal of this dissertation is the theoretical development of the Ricci flow, a differential equation over a family of Riemannian metrics on an arbitrary differentiable manifold, and its use in the proof of the so-called ...
Síntese de catalisadores básicos na presença de surfactantes hexadeciltrimetilamônio
(Universidade Federal de São Carlos, 2023-06-12)
The synthesis of two basic catalysts — CTA-MCM-41 and ZIF-8 — were studied in the presence of the surfactant hexadecyltrimethylammonium bromide (CTAB), which forms micelles in aqueous dispersions. The catalysts were ...
Desenvolvimento de compósitos de polímero ionomérico e metal baseados em poli(éter-éter-cetona) sulfonados
(Universidade Federal de São Carlos, 2023-07-26)
Ionic polymer-metal composites (IPMCs) are smart and bio-inspired materials that have a metal/polymer/metal sandwich structure. These are capable of deforming in response to electrical stimuli and vice versa, being promising ...
Programação da produção em ambientes de manufatura aditiva: análise do estado-da-arte e proposta de método de resolução
(Universidade Federal de São Carlos, 2023-05-05)
With the advancement of production technologies and materials, it is currently possible
to use Additive Manufacturing (AM), also known as 3D printing, for the large-scale
production of finished products, with numerous ...
