Compute Host Availability for Blood Feeding

Compute the availability of the population strata defined in the model as hosts for blood feeding by mosquitoes

Usage

compute_W(search_weights, H, TaR)

Arguments

search_weights: blood feeding search weights for the host strata
H: host density
TaR: the host species index

Value

host availability, a vector

Details

Host availability to blood searching mosquitoes in patches is the sum of search weights of the human strata, a vector $\omega$, weighted by time at risk, defined by a matrix $\Psi$ that is $n_p \times n_h$. The search weight is a per-capita measure so we weight it by human population density, $H$. Availability, $W$ is computed as $$\Psi \cdot (\omega H).$$
