We show that a simple relaxation scheme of the type proposed by Jin and Xin [Comm. Pure Appl. Math. 48, 235 (1995)] can be reinterpreted as defining a particular approximate Riemann solver for the original system of m conservation laws. Based on this observation, a more general class of approximate
and is divided into five uniform segments. For the explicit scheme, the time sample was chosen as 0.053 LM. The ลฝ . current at the location 0.0; y0.1 is shown in Figure 4. Again, the agreement is good, and it is seen that for the implicit scheme, one can make โฌ t large and violate the Courant stabil
relations and standard errors are indicative of the robustness of these equations. Therefore, the equations appear to be a useful tool in establishing the most efยฎcient way of utilizing exposure measurements.
