We consider the problem of planting a tree in a planting box located near a pipe line carrying hot steam.
Heat is transfered from the steam line to the surrounding ground, including the planting box.
We consider the effect that lining two sides of the box with insulation has on the temperature distribution over the area. Download postscript-file of the report. The propagation of calcium ions in cardiac cells is modeled by a system of three reaction diffusion equations. Calcium ions are released at certain points in the cell according to a probability function that relies on the concentration of the ions. Unfortunately, this creates a discontinuous forcing term in our system that relies on the delta function.
