Aurentz, Jared L.; Mach, Thomas; Vandebril, Raf; Watkins, David S.
(SIAM Journal on Matrix Analysis and Applications, 2015)
A stable algorithm to compute the roots of polynomials is presented. The roots are found by computing the eigenvalues of the associated companion matrix by Francis's implicitly shifted QR algorithm. A companion matrix is ...

(arXiv, 2016-11-30)
In the last decade matrix polynomials have been investigated with the primary focus on adequate linearizations and good scaling techniques for computing their eigenvalues. In this article we propose a new backward stable ...

(Electronic Transactions on Numerical Analysis, 2015)
A fast Fortran implementation of a variant of Gragg's unitary Hessenberg QR algorithm is presented. It is proved, moreover, that all QR- And QZ-like algorithms for the unitary eigenvalue problems are equivalent. The algorithm ...

The goal of this project is to calculate the temperature distribu-
tion of certain pressure-driven non-Newtonian
ows inside a circular tube.
The rheology under consideration is the type in which the shear stress is ...

The main purpose of our Capstone project is to study the Risk-Adjusted
Pricing Methodology (RAMP) Black-Scholes model and to find the finite
element solutions of the nonlinear Black-Scholes equation. The RAPM
is one of ...

We report a measurement of muon-neutrino disappearance in the T2K experiment. The 295-km muon-neutrino beam from Tokai to Kamioka is the first implementation of the off-axis technique in a long-baseline neutrino oscillation ...

A real-space, real-time implementation of time-dependent density functional theory is used to study
electron field emission from nanostructures. Carbon nanotubes and graphene nanoribbons are used as
model systems. The ...

We have performed very accurate quantum mechanical calculations of the five lowest S states of the
beryllium atom. In the nonrelativistic part of the calculations we used the variational method and we explicitly
included ...

(From Data to Models and Back, 2021-03)
The transfer of information processed by human beings from their short-term memory (STM) to their semantic memory creates two kinds of knowledge: a semantic network of associations and a structured set of rules to govern ...

(From Data to Models and Back, 2021-03-05)
Biofilms are structured communities of bacterial cells adherent to a surface. This bacterial state is called sessile.
This paper focuses on the modelling of the transition between planktonic and sessile state using ...

We show that for every n 1, there exists a 1n -computable family which up to equivalence has exactly one Friedberg numbering which does not induce the least element of the corresponding Rogers semilattice.
