The computation of Jordan blocks in parameter-dependent matrices
This paper extends the implicit determinant method introduced by Spence & Poulton (2005, J. Comput. Phys., 204, 65–81) to obtain a numerical technique for the calculation of a two-dimensional Jordan block in a...

Lyapunov inverse iteration for identifying Hopf bifurcations in models of incompressible flow
The identification of instability in large-scale dynamical systems caused by Hopf bifurcation is difficult because of the problem of identifying the rightmost pair of complex eigenvalues of large sparse generalized eigenvalue...

Convergence of Restricted Additive Schwarz with impedance transmission conditions for discretised Helmholtz problems
The Restricted Additive Schwarz method with impedance transmission conditions, also known as the Optimised Restricted Additive Schwarz (ORAS) method, is a simple overlapping one-level parallel domain decomposition method...
Calculating the $H_{\infty}$-norm Using the Implicit Determinant Method
We propose a fast algorithm to calculate the $H_{\infty}$-norm of a transfer matrix. The method builds on a well-known relationship between singular values of the transfer function and pure imaginary eigenvalues of a...

Sharp bounds on Helmholtz impedance-to-impedance maps and application to overlapping domain decomposition
We prove sharp bounds on certain impedance-to-impedance maps (and their compositions) for the Helmholtz equation with large wavenumber (i.e., at high frequency) using semiclassical defect measures. Gong et al. (Numer. Math....
The Application of Systems Engineering to Project Management
Brian Galli
Jan 01, 2020
This study investigated the application of systems engineering to project management. There is an increasing complexity to modern projects, and lifecycle-focused project management displays the inability to manage the risks...

Wavenumber-Explicit Bounds in Time-Harmonic Acoustic Scattering
We prove wavenumber-explicit bounds on the Dirichlet-to-Neumann map for the Helmholtz equation in the exterior of a bounded obstacle when one of the following three conditions holds: (i) the exterior of the obstacle is...

Optimization Methods in Continuous Improvement Models
Brian Galli
Jan 01, 2019
There are numerous processes used to implement quality, such as TQM, 6 Sigma, and Lean. For these quality processes to remain effective, a continuous improvement model is required and implemented from time to time. Some of these...

Inexact inverse subspace iteration with preconditioning applied to non-Hermitian eigenvalue problems
Convergence results are provided for inexact inverse subspace iteration applied to the problem of finding the invariant subspace associated with a small number of eigenvalues of a large sparse matrix. These results are...
Environmental attitudes of polluting SMEs
In this paper we explore the environmental attitudes of polluting SMEs (small-scale firms that produce or deal with environmentally sensitive goods) from the perspective of owner/managers in a low-income developing country...
Practitioner's View on the Future of Economic Decision-Making in Project Management
Brian Galli
Jul 01, 2019
As of now, the best means to plan for the future is project management because it has been proven effective in problem-solving and generating solutions. Few projects entail economic decision-making because of the cost factor...

Bounding acoustic layer potentials via oscillatory integral techniques
E. A. Spence
Mar 01, 2015
We consider the Helmholtz single-layer operator (the trace of the single-layer potential) as an operator on (Formula presented.) where (Formula presented.) is the boundary of a 3-d obstacle. We prove that if (Formula presented.)...
