This chapter describes a classical technique for constructing solutions of hyperbolic PDEs. The method is applied to linear systems of PDEs and to nonlinear PDE problems. This naturally leads to a discussion of more advanced topics including shocks, Riemann problems and weak solutions.

On the Characteristics of Method-of-Stages
IEEE Transactions on Reliability, 1979This paper examines the pdf of the ``series-stages in parallel'' and shows that depending upon the parameters, its shape can be multimodal.

The method of characteristics has played an essential role in computing hydraulic transients up to now. Almost all applicable software tools are based on this method. In principle, the method of characteristics is a mathematical technique for solving so-called hyperbolic partial differential equations.

The purpose of this chapter is to develop the method of characteristics for the solution of dynamic problems in thermoelasticity. The theoretical analysis of dynamic stresses due to impact loadings has generally been performed by the Laplace transform method.

A Variant of the Method of Characteristics
Computer assisted mechanics and engineering sciences, 2002A variant of the method of characteristics for hyperbolic conservation laws is proposed in this paper. It is based on the time interpolation instead of space interpolation as in the standard method of characteristics. A new method for calculating the propagation velocity is proposed as well.

The governing equations of motion for two and three-dimensional inviscid irrotational supersonic flows are derived. Although these equations are nonlinear, there are unique curves in the physical space, known as characteristics that turn the governing partial differential equations into ordinary differential equations that may be integrated along the ...

Memory characteristics of iterative methods
Proceedings of the 1999 ACM/IEEE conference on Supercomputing, 1999Conventional implementations of iterative numerical algorithms, especially multigrid methods, merely reach a disappointing small percentage of the theoretically available CPU performance when applied to representative large problems. One of the most important reasons for this phenomenon is that the current DRAM technology cannot provide the data fast ...
