2.2 Scalar Balance Law in a Bounded Domain In this part, we introduce the partial differential equation that is obtained in the hydrodynamic limit for the model defined in the previous section. Let $$\begin{aligned} J(u):= (2p-1) u (1-u), \quad G(x,u):= V(x) (u-\rho (x)...

Using Newton's second law of motion, we can write Hooke's law as follows (1.68)m(d2xdt2)+kx=0 where m is the mass of the spring. This is a second-order linear differential equation. Its characteristic equation is mr2+k=0, which has two complex roots given by r=±I˙k/m, where...

Assuming propagation of chaos (a property proved in a companion paper, De Masi et al., http://arxiv.org/abs/1104.3447 ) we prove convergence in the limit N →∞ to the linear heat equation with Dirichlet condition on the boundaries; the boundary conditions however are not known a priori,...
The heating of simple geometric objects immersed in an isothermal bath is analysed qualitatively through Fourier's law. The approximate temperature evolution is compared with the exact solution obtained by solving the transport differential equation, the discrepancies being smaller than 20%. Our method ...
As seen in Equation (7), particle relaxation time, ¿ , is a function of the local gas thermal condition, however, it is widely accepted that one ignores the local dependence and de nes the relax- ation time based on the gas condition in a special point. Some authors use the ...
