TD-EFIE with 3-Point Backward Difference and Stability Investigation
It is presented a new formulation using the time-domain electric field integral equation formulation (TD-EFIE) to obtain a transient scattering from conducting structures. The time derivative of the magnetic vector potential is approximated by 3-poin...

Compressions of Stable Contractions
The stability of compressions of stable contractions is studied and a sufficient orbit condition is given. On the other hand, it is shown that there are non-stable compressions of the 1-dimensional backward shift and a complete of b...

Numerical Stability of Block Toeplitz Algorithms in Polynomial Matrix Computations
We study the problem of computing the eigenstructure of a polynomial matrix. Via a backward error analysis we analyze the stability of some block Toeplitz algorithms to obtain this eigenstructure. We also elaborate on the nature of ...

The Transitional Backward-Facing Step Flow in a Water Channel with Variable Expansion Geometry
The backward-facing step flow is investigated experimentally and numerically at moderate Reynolds numbers. The different channel expansion ratios (ER = 1.4, 2, 2.5, and 4) and inlet flow conditions (steady and pulsatile) are applied with the...

On Numerical Stability in Large Scale Linear Algebraic Computations
In iterative methods, rounding errors have two main effects: They can delay convergence and they can limit the maximal attainable accuracy. We present some examples of rounding error analysis that are fundamental to justify numerically computed resul...

The stability analysis of a discretized pantograph equation
The paper deals with a difference equation arising from the scalar pantograph equation via the backward Euler discretization. A case when the solution tends to zero but after reaching a certain index it loses this tendency is discussed. We a...
