Dinâmicas estocásticas em teoria de jogos : percolação, cooperação e seus limites
(2018) [Dissertação]O estudo de Teoria de Jogos tem se expandido para diversas áreas, tendo sua aplicação inicial na economia, hoje é utilizado na psicologia, na filosofia e tem um papel importantíssimo na biologia evolutiva. O seu sucesso ... -
Domain-size heterogeneity in the Ising model : geometrical and thermal transition
(2015) [Artigo de periódico]A measure of cluster size heterogeneity (H), introduced by Lee et al. [Phys. Rev. E 84, 020101 (2011)] in the context of explosive percolation, was recently applied to random percolation and to domains of parallel spins ... -
Dynamical cluster size heterogeneity
(2020) [Artigo de periódico]Only recently has the essential role of the percolation critical point been considered on the dynamical properties of connected regions of aligned spins (domains) after a sudden temperature quench. In equilibrium, it is ... -
Dynamic facilitation picture of a higher-order glass singularity
(2010) [Artigo de periódico]We show that facilitated spin mixtures with a tunable facilitation reproduce, on a Bethe lattice, the simplest higher-order singularity scenario predicted by the mode-coupling theory (MCT) of liquid-glass transition. ... -
Efeito de memória e reputação em teoria de jogos
(2023) [Trabalho de conclusão de graduação]O Dilema do Prisioneiro é um modelo clássico em teoria de jogos para o estudo sobre a cooperação entre agentes a princípio egoístas. Este trabalho busca investigar o efeito da memória das interações prévias na dinâmica de ... -
Energy-lowering and constant-energy spin flips : emergence of the percolating cluster in the kinetic Ising model
(2022) [Artigo de periódico]After a sudden quench from the disordered high-temperature T0 → ∞ phase to a final temperature well below the critical point TF Tc, the nonconserved order parameter dynamics of the two-dimensional ferromagnetic Ising model ... -
Um estudo de percolação em barragens de terra, em regimes permanente e transiente, com a aplicação do método de elementos finitos
(1988) [Dissertação]Este trabalho apresenta um estudo de fluxo de água em barragens de terra, em regimes permanente e transiente, com a utilização do Método de Elementos Finitos. No estudo de fluxo em regime permanente duas formas de abordar ... -
Generalized mean-field approximations for evolutionary games on lattices
(2021) [Dissertação]Evolutionary game theory offers interesting models for the study of the emergence and maintenance of cooperation. One mechanism that can maintain cooperation in a Prisoner’s Dilemma is affixing players in a network, under ... -
Geometric properties of spin models : cluster size heterogeneity
(2021) [Tese]Many systems are continually evolving in nature. In contrast to phenomena at, or close to, equilibrium, the behavior of out of equilibrium systems is much less understood. The geometrical characterization of the structures, ... -
Leaching of atrazine in commercial and xerogel formulations in oxisol using bioassay and chromatographic methods
(2015) [Artigo de periódico]Mobility of atrazine in soil has contributed to the detection of levels above the legal limit in surface water and groundwater in Europe and the United States. The use of new formulations can reduce or minimize the impacts ... -
Leaching of the S-metolachlor herbicide associated with paraquat or glyphosate in a no-tillage system
(2016) [Artigo de periódico]The combined use of desiccant and residual herbicides is a common management practice under no-tillage systems. However, the effect of desiccant herbicides and mulch on the leaching of residual herbicide is unknown. This ... -
Microscopic models of mode-coupling theory : the F12 scenario
(2012) [Artigo de periódico]We provide extended evidence that mode-coupling theory (MCT) of supercooled liquids for the F12 schematic model admits a microscopic realization based on facilitated spin models with tunable facilitation. Depending on the ... -
Mobilidade vertical de cátions influenciada pelo método de aplicação de cloreto de potássio em solos com carga variável
(2007) [Artigo de periódico]A magnitude da mobilidade vertical dos nutrientes no perfil afeta o contato destes com as raízes e a lixiviação e, por isso, influencia a época e o método de aplicação dos fertilizantes ao solo. O presente trabalho objetivou ... -
Percolation and cooperation with mobile agents geometric and strategy clusters
(2014) [Artigo de periódico]We study the conditions for persistent cooperation in an off-lattice model of mobile agents playing the Prisoner’s Dilemma game with pure, unconditional strategies. Each agent has an exclusion radius rp , which accounts ... -
Percolation approach to glassy dynamics with continuously broken ergodicity
(2014) [Artigo de periódico]We show that the relaxation dynamics near a glass transition with continuous ergodicity breaking can be endowed with a geometric interpretation based on percolation theory. At the mean-field level this approach is consistent ... -
