Avaliando a influência de indivíduos imunes na propagação de doenças contagiosas
(Universidade Presbiteriana Mackenzie, 2016-02-01)
Epidemiology is the science that studies the occurrence of diseases in a population. The results of these studies allow a comprehension of a disease propagation and enable actions in order to control epidemics. There are ...
Extração de contornos de figuras via sincronismo em redes de osciladores com acoplamento dinâmico
(Universidade Presbiteriana Mackenzie, 2006-09-18)
A variant of Kuramoto's model for phase oscillators with dynamic coupling is studied. The coupling weight is adjusted by the phase difference resulting in a connection which is strengthened for synchronized oscillators and ...
Método para determinação dos pesos sinápticos em uma rede de PLLs reconhecedora de imagens
(Universidade Presbiteriana Mackenzie, 2006-09-11)
Recognition of patterns can be performed by using neural networks built with oscillators, like phase-locked loops (PLLs). These networks are modeled with differential equation systems and can be studied by using Dynamical ...
Uma investigação epidemiológica baseada em autômato celular probabilista assíncrono
(Universidade Presbiteriana Mackenzie, 2018-05-30)
In epidemiology, analytical and computational models are used to study the dynamics of the spreading of contagious diseases. The goal is to predict the temporal evolution of the number of sick individuals and to evaluate ...
Previsão de séries temporais epidemiológicas usando autômatos celulares e algoritmos genéticos
(Universidade Presbiteriana Mackenzie, 2010-08-02)
SIS (susceptible-infected-susceptible) and SIR (susceptible-infectedremoved) epidemiological models based on probabilistic cellular automaton (PCA) are used in order to simulate the temporal evolution of the number of ...
Um modelo de sistema visual baseado em redes de Newman-Watts acopladas
(Universidade Presbiteriana Mackenzie, 2016-07-27)
Here, the occurrence of synchronism in coupled Newman-Watts graphs is studied, as a model of neural network. The inspiration for this study comes from the visual system of mammals. The whole network is formed by four ...
