Here’s some machine code from a MIPS processor: 00000000101000010000000000011000 00000000100011100001100000100001 10001100011000100000000000000000 10001100111100100000000000000100 10101100111100100000000000000000 10101100011000100000000000000100 00000011111000000000000000001000 Okay... did that make sense? Probably not. • source: http://www.eas.asu.edu/~gupta/intro.html Computer Programming
Lets look at it in MIPS assembly language: swap: muli $2, $5,4 add $2, $4,$2 lw $15, 0($2) lw $16, 4($2) sw $16, 0($2) sw $15, 4($2) jr $31 Now does that make sense? Better, but still cryptic. • source: http://www.eas.asu.edu/~gupta/intro.html Computer Programming
What about a high level language, like C swap(int v[], int k) { int temp; temp = v[k]; v[k] = v[k+1]; v[k+1] = temp; } This probably still doesn’t make sense to most of you. That’s okay. However, you could probably parse it after I explained what everything was. • source: http://www.eas.asu.edu/~gupta/intro.html Computer Programming

a cellular automaton • Cellular automaton A is a set of four objectsA = <G, Z, N, f>, where • G– set of cells • Z– set of possible cells states • N – set, which describes cells neighborhood • f– transition function, rules of the automaton: • Z|N|+1Z (for automaton, which has cells “with memory”) • Z|N|Z (for automaton, which has “memoryless” cells) Moore Neighbourhood (in grey) of the cell marked with a dot in a 2D square grid

the dynamics Mollusk population dynamics (3a) a growth model for the number of individuals (N) that considers the intrinsic growth rate (r) and the maximum sustainable yield or carrying capacity (C) defined at each site (Verhulst, 1838): the model calculates the local increase of population using equation 1 and calculating N(t+1) out from N(t). The values for r and C are set at each site and each time step, using monthly meteorological inputs and considering the ecological quality of the habitat (3b) (1) Human infection dynamics (SIR - SI) This model splits the human population into three compartments: S (for susceptible), I (for infectious) and R (for recovered and not susceptible to infection) and the snail population into two compartments: MS (for susceptible mollusk) and MI (for infectious mollusk). Socioeconomic and environmental factors environmental quality of the nine collection sites in Carne de Vaca, according to the criteria of Callisto et al (Souza et al, 2010).
Cells and infection forces • states • black: rate of human infection = 100%; • red: 80% ≤ rate of human infection < 100%; • light red: 60% ≤ rate of human infection < 80%; • yellow: 40% ≤ rate of human infection < 60%; • light yellow: 20% ≤ rate of human infection < 40%; • cyan: 0% ≤ rate of human infection < 20%. • infection forces • Human • S -> I (infected molluscs contact, pH) • I -> R (if treated (1-α), χ) • Molluscs • S -> I (infected human contact, pM)
