#### Invariant measures for the tochastic von Karman plate equation

(Siam Publications, 2005)

We prove the existence of an invariant measure for the von Karman plate equation with random noise. The nonlinear term which symbolizes the von Karman equation inhibits the standard procedure for the existence of an invariant ...

#### Short wave stability for inviscid shear flow

(Siam Publications, 2008)

We consider the linear stability of inviscid shear flows. While it is well known that discontinuous velocity profiles lead to short wave instabilities and ill-posedness, known examples of instability for smooth profiles ...

#### Draw resonance revisited

(Siam Publications, 2006)

We consider the problem of isothermal fiber spinning in a Newtonian fluid with no inertia. In particular, we focus on the effect of the downstream boundary condition. For prescribed velocity, it is well known that an ...

#### Preconditioners for generalized saddle-point problems

(Siam Publications, 2006)

We propose and examine block-diagonal preconditioners and variants of indefinite preconditioners for block two-by-two generalized saddle-point problems. That is, we consider the nonsymmetric, nonsingular case where the ( ...

#### On a stochastic hyperbolic system in linear elasticity

(Siam Publications, 2000-08)

In this paper we discuss the Cauchy problem for linear elasticity with a space-time white noise forcing term. We show that the solution can be represented by a formula analogous to the Riesz formula for solutions of a wave ...

#### 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 Integral Inequalities in Two Independent Variables and Their Applications

(Hindawi Publishing Corporation, 2007-11-05)

This paper generalizes results of Cheung and Ma (2005) to more general inequalities with more than one distinct nonlinear term. From our results, some results of Cheung and Ma ( 2005) can be deduced as some special cases. ...

#### Structured noncommutative multidimensional linear systems

(Siam Publications, 2005)

We introduce a class of multidimensional linear systems with evolution along a free semigroup. The transfer function for such a system is a formal power series in noncommuting indeterminates. Standard system-theoretic ...

#### Field-induced motion of ferrofluid droplets through immiscible viscous media

(Cambridge University Press, 2008-09)

The motion of a hydrophobic ferrofluid droplet placed in a viscous medium and driven by an externally applied magnetic field is investigated numerically in an axisymmetric geometry. Initially, the drop is spherical and ...

#### Fluid Limits of Optimally Controlled Queueing Networks

(Hindawi, 2007-08-21)

We consider a class of queueing processes represented by a Skorokhod problem coupled with a controlled point process. Posing a discounted control problem for such processes, we show that the optimal value functions converge, ...
