Análise espectral dos autômatos celulares elementares
(Universidade Presbiteriana Mackenzie, 2012-12-11)
The Fourier spectra of cellular automata rules give a characterisation of the limit configurations generated by them at the end of their time evolution. In the present work, the Fourier spectra of each rule of the elementary ...
Nova caracterização da noção de reversibilidade parcial para autômatos celulares unidimensionais em reticulado cíclico, com foco no espaço elementar
(Universidade Presbiteriana Mackenzie, 2015-11-23)
Cellular automata are discrete dynamic systems that by local action rules, even very simple, can present arbitrarily complex global processing. The reversibility is a property that a few rules have and guarantees the ...
Uso de rede de Kohonen para a clusterização de objetos de aprendizagem
(Universidade Presbiteriana Mackenzie, 2007-08-08)
The increasing availability of digital education resources in the Internet, called learning objects, has been followed by the definition of indexation standards. However, the lack of consensus about the definition of ...
Análise espectral de sinais caóticos gerados por mapas unidimensionais
(Universidade Presbiteriana Mackenzie, 2008-06-26)
In this work, we investigate characteristics of the Power Spectral Density (PSD) of chaotic signals generated by one-dimensional maps. Usually, these signals are mentioned as having broadband and impulsive Autocorrelation ...
Um algoritmo bioinspirado para agrupamento de dados
(Universidade Presbiteriana Mackenzie, 2010-05-03)
This dissertation discusses the use of bio-inspired algorithms for data clustering, with emphasis on a model of emergent collective behavior of agents and a new clustering algorithm called cBoids is presented. The cBoids ...
