Low energy $n-\nuc{3}{H}$ scattering : a novel testground for nuclear interaction
R. Lazauskas, J. Carbonell, A. C. Fonseca +3
The low energy $n-\nuc{3}{H}$ elastic cross sections near the resonance peak are calculated by solving the 4-nucleon problem with realistic NN interactions. Three different methods…
Less is More - Genetic Optimisation of Nearest Neighbour Classifiers
Vitorino Ramos, Fernando Muge
The present paper deals with optimisation of Nearest Neighbour rule Classifiers via Genetic Algorithms. The methodology consists on implement a Genetic Algorithm capable of search…
ANTIDS: Self-Organized Ant-based Clustering Model for Intrusion Detection System
Vitorino Ramos, Ajith Abraham
Security of computers and the networks that connect them is increasingly becoming of great significance. Computer security is defined as the protection of computing systems against…
The Go model revisited: Native structure and the geometric coupling between local and long-range contacts
P. F. N. Faisca, M. M. Telo da Gama, A. Nunes
Monte Carlo simulations show that long-range interactions play a major role in determining the folding rates of 48-mer three-dimensional lattice polymers modelled by the Go potenti…
Deterministic Bak-Sneppen model. Lyapunov spectrum and avalanches as return times
R. Vilela Mendes
A deterministic version of the Bak-Sneppen model is studied. The role of the Lyapunov spectrum in the onset of scale-free behavior is established and avalanches are interpreted as…
Recurrent epidemics in small world networks
J. Verdasca, M. M. Telo da Gama, A. Nunes +3
The effect of spatial correlations on the spread of infectious diseases was investigated using a stochastic SIR (Susceptible-Infective-Recovered) model on complex networks. It was…
