Teorema Fundamental do Cálculo: uma proposta de abordagem a partir da modelagem matemática com auxílio do Geogebra
(Universidade Federal de São Carlos, 2021-11-25)
The disciplines Differential and Integral Calculus for STEM students require a
precise understanding of the themes to avoid it being an arduous path of learning
and building a solid foundation, and it is the teacher's ...
Caracterização de scaffolds a base de colágeno tipo I aniônico visando tratamento de lesões na pele
(Universidade Federal de São Carlos, 2022-02-22)
Skin lesions can reach different intensities along the tissue, being the deepest those that affect all layers of the skin (epidermis, dermis and hypodermis), hampering the self-healing natural process. These make it essential ...
Atomização a gás da liga de alumínio AA2017: efeitos dos parâmetros de processo nas características físicas dos pós produzidos visando aplicação em manufatura aditiva
(Universidade Federal de São Carlos, 2022-07-15)
Gas atomization is the main method to produce metal powders for LASER powder bed fusion (L-PBF), which is an additive manufacturing (AM) technique. It produces metallic powders with suitable characteristics to be applied ...
Minimização do risco de carteiras de investimento através da programação linear e da teoria de Markowitz
(Universidade Federal de São Carlos, 2022-07-15)
The study presented in this project aimed at the formation and optimization of portfolios with 20 shares traded on B3 based on Markowitz's modern portfolio theory and Linear Programming, considering the minimization of ...
Análise comparativa de benchmarks para banco de dados NoSQL orientados a grafos de propriedades
(Universidade Federal de São Carlos, 2021-07-06)
The new era of data economics, based on data sets with enormous volume, wide variety of formats, and rapid speed in data production and utilization, has brought the need for new data management structures and methods. Then ...
Intermittent drying and draft tube design for spouted bed
(Universidade Federal de São Carlos, 2021-12-08)
The conventional spouted bed has presented several limitations that restrict the use on an industrial scale. Thus, studies of different methodologies and configurations have been performed to overcome such limitations. ...
Efeito do tamanho e distribuição de tamanho inicial das partículas da hematita, na cinética de sinterização assistida por micro-ondas
(Universidade Federal de São Carlos, 2021-11-26)
This thesis aimed to study the effect of the initial particle size and its
distribution of hematite on microwave-assisted sintering kinetics. Two synthesis
methods were used: sol-gel and seeded-mediated growth. By sol-gel ...
Monitoramento de um processo de lixiviação de cobre em placas de circuito impresso por meio da análise direta de sólidos e uso de Laser-Induced Breakdown Spectroscopy (LIBS)
(Universidade Federal de São Carlos, 2021-12-03)
This PhD thesis was developed at CTI Renato Archer, Campinas-SP and was based on a hydrometallurgical process, on an industrial scale, applied to the recovery of metals in discarded printed circuit boards (PCBs). The ...
Differential cohomology on maps of pairs and relative-parallel product
(Universidade Federal de São Carlos, 2021-10-06)
In this thesis, we study three important topics. The first one provides an axiomatic framework to differential cohomology on maps of pairs of topological spaces, introducing the product between relative and parallel classes. ...
Avaliação da disponibilidade de fósforo em fertilizantes encapsulados
(Universidade Federal de São Carlos, 2021-11-11)
The concentration of gradient diffusion was used as a passive sampling technique to mimic the physicochemical adsorption of P by plant roots. For this purpose, a binding gel was synthesized from agarose, polyacrylamide, ...
