#### Approximate Deconvolution Reduced Order Modeling

This paper proposes a large eddy simulation reduced order model(LES-ROM) framework for the numerical simulation of realistic flows. In this LES-ROM framework, the proper orthogonal decomposition(POD) is used to define the ...

#### Sound-ultrasound interaction in bubbly fluids: Theory and possible applications

(American Institute of Physics, 2001-12)

The interaction between sound and ultrasound waves in a weakly compressible viscous liquid with gas bubbles is considered. Using the method of multiple scales one- and two-dimensional nonlinear interaction equations are ...

#### Scalings for fragments produced from drop breakup in shear flow with inertia

(American Institute of Physics, 2001-08)

When a drop is sheared in a matrix liquid, the largest daughter drops are produced by elongative end pinching. The daughter drop size is found to scale with the critical drop size that would occur under the same flow ...

#### Dynamics of self-driven microcantilevers

(American Institute of Physics, 2002-04-01)

The small amplitude thermal vibrations of the microcantilever of an atomic force microscope can be enhanced via a delayed feedback system. This is verified experimentally for a triangular cantilever, and modeled theoretically ...

#### Using startup of steady shear flow in a sliding plate rheometer to determine material parameters for the purpose of predicting long fiber orientation

(AIP Publishing, 2012-07-01)

The properties of long glass fiber reinforced parts, such as those manufactured by means of injection molding and compression molding, are highly dependent on the fiber orientation generated during processing. A sliding ...

#### Interpolatory projection methods for parameterized model reduction

(Siam Publications, 2011)

We provide a unifying projection-based framework for structure-preserving interpolatory model reduction of parameterized linear dynamical systems, i.e., systems having a structured dependence on parameters that we wish to ...

#### H-2 model reduction for large-scale linear dynamical systems

(Siam Publications, 2008)

The optimal H-2 model reduction problem is of great importance in the area of dynamical systems and simulation. In the literature, two independent frameworks have evolved focusing either on solution of Lyapunov equations ...

#### NONLINEAR PARAMETRIC INVERSION USING INTERPOLATORY MODEL REDUCTION

(Siam Publications, 2015-01-01)

#### A New Topological Degree Theory for Perturbations of Demicontinuous Operators and Applications to Nonlinear Equations with Nonmonotone Nonlinearities

(Hindawi, 2016-10-18)

Let 𝑋 be a real reflexive locally uniformly convex Banach space with locally uniformly convex dual space 𝑋∗. Let 𝑇 : 𝑋 ⊇ 𝐷(𝑇)→ 2𝑋∗ be maximal monotone of type 𝚪𝜙 𝑑 (i.e., there exist 𝑑 ≥ 0 and a nondecreasing ...
