Analysis and Prognosis of Failures in Intelligent Hybrid Systems Using Bioengin...

This work is of multidisciplinary concept, whose development is difficult to perform. Considering also that, in one of the steps, the similarity between the FRF of the vibration and acoustic signal is demonstrated. The objective of this work is the analysis and prognosis of the progression of failures of a pair of gears using the artificial immune system (AIS) of negative selection. In order to have this condit...

Swarm control designs applied to a mechanical oscillator

Made available in DSpace on 2022-04-29T08:44:12Z (GMT). No. of bitstreams: 0 Previous issue date: 2008-12-01; This paper presented the particle swarm optimization approach for nonlinear system identification and for reducing the oscillatory movement of the nonlinear systems to periodic orbits. We analyzes the non-linear dynamics in an oscillator mechanical and demonstrated that this model has a chaotic behavior...

Failure prognosis in a piston flow reactor of the tubular reactor using artific...

Industry 4.0 uses principles of new technologies to achieve better quality and productivity results, which intelligent computing is one of them. In this work is proposed an intelligent methodology in which the artificial immune system sequesters the signal into groups and determines the classification based on failure prognose by the degree of severity of a tubular reactor with piston flow. The process is devel...

Analysis of Structural Integrity Using an ARTMAP-Fuzzy Artificial Neural Network

Made available in DSpace on 2015-03-18T15:56:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01; This paper presents the application of artificial neural networks in the analysis of the structural integrity of a building. The main objective is to apply an artificial neural network based on adaptive resonance theory, called ARTMAP-Fuzzy neural network and apply it to the identification and character...

Artificial Immune Systems with Negative Selection Applied to Health Monitoring ...

Made available in DSpace on 2014-12-03T13:11:51Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-01; In this paper we present a system for aircraft structural health monitoring based on artificial immune systems with negative selection. Inspired by a biological process, the principle of discrimination proper/non-proper, identifies and characterizes the signs of structural failure. The main application ...

Remarks on parametric surface waves in a nonlinear and non-ideally excited tank

Dinamica e controle não lineares de um sistema neuronal ideal e nã-ideal

Orientadores: Jose Manoel Balthazar, Helder Anibal Hermini; Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Engenharia Mecanica; Resumo: Nesta tese de doutorado, estuda-se o comportamento da membrana plasmática modelada através de um circuito elétrico. O modelo elétrico foi desenvolvido por Hodgkin e Huxley em 1952 e trata da variação do tempo em relação à condutância de íons de potássio e só...
