Tytuł:: Simulating the spread of the BSE disease: a cellular automata approach
Autorzy:: Magdoń-Maksymowicz, M.
Maksymowicz, A. Z.
Powiązania:: https://bibliotekanauki.pl/articles/1964173.pdf
Data publikacji:: 2005
Wydawca:: Politechnika Gdańska
Tematy:: computer simulation
disease spreading
BSE
cellular automata method
Opis:: The rules of evolution applied in the cellular automata approach may correspond to the propagation of the mad cow disease. In a computer simulation of the BSE disease's spread both inherited and infectious mechanisms are accounted for. The initial population of items is randomly distributed on a two-dimensional square lattice, Nx × Ny = 1000 × 1000, with a fraction of 1 percent the items already infected. Alternatively, faulty prions may spontaneously develop during the simulation with a very small frequency. Our results indicate a critical probability, pc, of BSE transmission, so that for p below the threshold the population recovers. For p > pc the disease is launched in the population with a dynamic equilibrium between the healthy and infected fractions of the population. The threshold is very sensitive to spatial clustering of the population and the detailed rules for the disease's onset, evolution and propagation.

Tytuł:: On Penna model of population evolution
Autorzy:: Magdoń-Maksymowicz, M.
Powiązania:: https://bibliotekanauki.pl/articles/1941717.pdf
Data publikacji:: 2000
Wydawca:: Politechnika Gdańska
Tematy:: population evolution
biological ageining
Penna model
bad mutations
migration process
logistic equation
Gompertz law
Opis:: Computer studies of population evolution are presented. Numerical calculations are based on the Penna model. This model accounts for mutation load of individuals resulting in non-trivial age (a) dependence of the mortality rate q(a) which may be compared with empirical data. The Penna model is also very flexible for suitable modifications of the population evolution process such as hunting, genetic death, migration etc. Here we present some examples of the population growth for different evolution rules. Calculations require about 100 MB memory for 10/sup 6/ population which is necessary to get reliable statistics. The typical running time for 3000 iteration steps is several hours for a HP S2000 machine.
