     2. The Act of Congress of July 4, 1836, section 6, requires an inventor who is desirous to take out a patent for his invention, to furnish a model of his invention, in all cases which admit of representation by model, of a convenient size to exhibit advantageously its several parts.

With the definition of two states of communication networks, high-delay state and low-delay state, it was discovered that the transition model of the two delay states could be predicted very precisely using a certain molecule's stochastic model of the state of transition between a high-energy state and a low-energy state.
When the fast processes of a continuous system are modeled by white noise--as is common for physical applications--the resulting stochastic model converges to a Stratonovich stochastic differential equation (Wong and Zakai 1965; Papanicolaou and Kohler 1974; Gardiner 1985; Penland 2003a,b).
In this section, we show that not only does the stochastic model (12) have a unique global solution but also the solution will remain within T whenever it starts from there.
In the next section we propose two stochastic models: the first one is an endemic model in which each person infected from outside source contributes a random amount of infectivity to the force of infectivity (or infectivity function) which decreases at a constant rate over the time.
