Simulation Analysis for Peak Pressure of Shock Wave Based on Lax-Friedrichs Method

2012 Fifth International Conference on Information and Computing Science, 2012
FEM software has been well-developed in shock wave simulation. As the software usually is huge and complicated, subdivision mesh needs lots of computation, and the precision is not assured, finite-difference methods are highly regarded. Difference schemes are related to the stability and precision.

Analysis of GRIN Lens Antennas through the Lax-Friedrichs Sweeping Method

2024 IEEE International Symposium on Antennas and Propagation and INC/USNC‐URSI Radio Science Meeting (AP-S/INC-USNC-URSI)
The analysis of Graded-Index (GRIN) lenses involves employing ray tracing algorithms, which address the Eikonal equation to determine phase distribution. Subsequently, the transport equation is solved to retrieve the amplitude. In this paper, we introduce a novel analysis approach based on a numerical technique known as the Lax-Friedrichs Sweeping ...

System und Systemkritik – Witz und Ironie als philosophische Methode beim frühen Friedrich Schlegel

Philosophisches Jahrbuch, 2013
Abstract. The conceptions of wit and irony of the early Friedrich Schlegel together constitute a philosophically ambitious form of early-romantic dialectic. This dialectic was directed especially against the closed philosophical system of Fichte, and tries to show a third way between the abandonment of a system and a closed system.

Discontinuous Galerkin Methods for Friedrichs' Systems. Part III. Multifield Theories with Partial Coercivity

SIAM Journal on Numerical Analysis, 2008
This paper is the third and last part of a work attempting to give a unified analysis of discontinuous Galerkin methods. The purpose of this paper is to extend the framework that has been developed in Part II for two-field Friedrichs' systems associated with second-order PDEs.

Lax–Friedrichs fast sweeping methods for steady state problems for hyperbolic conservation laws

Journal of Computational Physics, 2013
Fast sweeping methods are efficient iterative numerical schemes originally designed for solving stationary Hamilton-Jacobi equations. Their efficiency relies on Gauss-Seidel type nonlinear iterations, and a finite number of sweeping directions. In this paper, we generalize the fast sweeping methods to hyperbolic conservation laws with source terms. The

Quasinilpotent variant of Friedrichs' method in the theory of similarity of linear operators

Functional Analysis and Its Applications, 1984
Let X denote a complex Banach space. A closed linear operator A on X is called non-quasianalytic, if it has a representation \(A=A_ 1+iA_ 2\), \(D(A)\subset D(A_ 1)\cap D(A_ 2)\), where \(iA_ 1\), \(iA_ 2\), are generators of strongly continuous groups of operators \(\{T_ 1(t)\}\), \(\{T_ 2(t)\}\), \(t\geq 0\), which commute, and \(\int (\log \| T_ k(t)
