Thin film deposition with time-varying temperature
(2013)
We study the effects of time-dependent substrate/film temperature in the deposition of a mesoscopically thick film using a statistical model that accounts for diffusion of adatoms without lateral neighbors whose coefficients ...
A vigilance decrement comes along with an executive control decrement: Testing the resource-control theory
(Springer, 2022-04)
A decrease in vigilance over time is often observed when performing prolonged tasks, a phenomenon known as “vigilance decrement.” The present study aimed at testing some of the critical predictions of the resource-control ...
Observer-based adaptive control using multiple-models switching and tuning
(Institution of Engineering and Technology, 2014-02)
Despite the remarkable theoretical accomplishments and successful applications of adaptive control, this field is not mature enough to solve challenging problems where strict performance and robustness guarantees are ...

Modelagem baseada em grafos para sistemas de controle descritos por espaços de estados
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia de ComputaçãoUTFPR, 2021-08-20)
In this work, a graph-based method is proposed to represent control systems described by state spaces. For this purpose, it is described the study of graph topological structures, which qualify and quantify the relations ...
Observations on interfacing loop quantum gravity with cosmology
(American Physical Society, 2015-12)
A simple idea of relating the loop quantum gravity (LQG) and loop quantum cosmology (LQC) degrees of freedom is introduced and used to define a relatively robust interface between these theories in context of toroidal ...
As expectativas cognitivas na sociedade hipercomplexa: uma leitura das audiências públicas à luz da teoria dos sistemas de Niklas Luhmann.
(Universidade Católica de Pernambuco, 2019-04-01)
It is expected by the modern society, that the Law is responsible for reducing the Social System’s high complexity. All conceptual construction of the Systems Theory helps to analyze the risk, the complexity and the ...
Desenvolvimento de modelos de falhas em redutores de engrenagens para diagnóstico via observadores de estado
(Universidade Estadual Paulista (Unesp), 2014-06-02)
The increased competition among companies have demanded higher operating speeds and shorter periods of maintenance of equipment, for this reason it is extremely important to be able to extend equipment life through the ...
