Interpolatory H-infinity model reduction
(Elsevier Science Bv, 2013-07-01)
Model Reduction by Rational Interpolation
The last two decades have seen major developments in interpolatory methods for model reduction of large-scale linear dynamical systems. Advances of note include the ability to produce (locally) optimal reduced models at ...
Numerical investigation of elongated drops in a microfluidic T-junction
(American Institute of Physics, 2011-02)
We present a combined numerical and asymptotic approach for modeling droplets in microchannels. The magnitude of viscous forces relative to the surface tension force is characterized by a capillary number, Ca, which is ...
Wolfgang von Ohnesorge
(American Institute of Physics, 2011-12)
This manuscript got started when one of us (G.H.M.) presented a lecture at the Institute of Mathematics and its Applications at the University of Minnesota. The presentation included a photograph of Rayleigh and made ...
Spontaneous penetration of a non-wetting drop into an exposed pore
(American Institute of Physics, 2013-05)
We consider the penetration process of a liquid drop approaching an exposed pore along the axis of symmetry, which is intended to model the penetration of non-wetting drops into a porous medium. Inertia and gravity are ...
A volume-of-fluid formulation for the study of co-flowing fluids governed by the Hele-Shaw equations
(American Institute of Physics, 2013-08)
We present a computational framework to address the flow of two immiscible viscous liquids which co-flow into a shallow rectangular container at one side, and flow out into a holding container at the opposite side. Assumptions ...
Phase-locked loops, demodulation, and averaging approximation time-scale extensions
(Siam Publications, 2013)
Among the many applications of the phase-locked loop (PLL), a device used extensively in telecommunications and electronics, is the demodulation of modulated carrier signals. The PLL contains a voltage controlled oscillator ...
An effective method for parameter estimation with pde constraints with multiple right-hand sides
(Siam Publications, 2012)
Often, parameter estimation problems of parameter-dependent PDEs involve multiple right-hand sides. The computational cost and memory requirements of such problems increase linearly with the number of right-hand sides. For ...
NONLINEAR PARAMETRIC INVERSION USING INTERPOLATORY MODEL REDUCTION

Abacus proofs of Schur function identities
(Siam Publications, 2010)
This article uses combinatorial objects called labeled abaci to give direct combinatorial proofs of many familiar facts about Schur polynomials. We use abaci to prove the Pieri rules, the Littlewood-Richardson rule, the ...
