Symbol | Meaning |
---|---|
t | release date and time |
x, y, h, | release coordinates |
q | release quantity |
n _{ i } | population of tract i |
c _{ i } | number of cases who live in tract i |
d _{ i } | dose of spores in the centroid of tract i |
θ _{ i } | ED-visit probability of each individual who lives in tract i, given that a release has occurred and assuming that commuting has not taken place |
G | commuting graph: nodes denote tracts, arcs denote commuting flows |
n _{ ij } | for i ≠ j, number of people who live in tract i and work in tract j; for i = j, number of people who live in tract i and who either don't work or work in tract i |
c _{ ij } | for i ≠ j, number of cases who live in tract i and work in tract j; for i = j, number of cases who live in tract i and who either don't work or work in tract i |
Out (i) | union of set {i} with the set of all tracts where people who live in tract i work |
