#### A finite element splitting extrapolation for second order hyperbolic equations

(Siam Publications, 2009)

Splitting extrapolation is an efficient technique for solving large scale scientific and engineering problems in parallel. This article discusses a finite element splitting extrapolation for second order hyperbolic equations ...

#### A uniqueness result for p-Monotone viscosity solutions of Hamilton-Jacobi equations in bounded domains

(Siam Publications, 2009)

We consider a class of Hamilton-Jacobi equations H(x, Du(x)) - 0 with no u-dependence and with continuity properties consistent with recent applications in queueing theory. Continuous viscosity solutions are considered in ...

#### Sufficient conditions and perfect duality in nonconvex minimization with inequality constraints

(American Institute of Mathematical Sciences, 2005-02)

The paper studies forced surface waves on an incompressible, inviscid fluid in a two-dimensional channel with a small negative or oscillatory bump on a rigid flat bottom. Such wave motions are determined by a non-dimensional ...

#### Transfer function approach to output specification in certain linear distributed parameter systems

(American Institute of Mathematical Sciences, 2003)

We carry out error estimation of a class of immersed finite element (IFE) methods for elliptic interface problems with both perfect and imperfect interface jump conditions. A key feature of these methods is that their ...

#### The PMU placement problem

(Siam Publications, 2005)

PMU placement problem is an optimization problem abstracted from an approach to supervising an electrical power system. The power system is modeled as a graph, and adequate supervision of the system requires that the voltage ...

#### A hybrid collocation method for volterra integral equations with weakly singular kernels

(Siam Publications, 2003)

The commonly used graded piecewise polynomial collocation method for weakly singular Volterra integral equations may cause serious round-off error problems due to its use of extremely nonuniform partitions and the sensitivity ...

#### Convergence theorems for intermediate problems. II

(Cambridge University Press, 2002)

Convergence theorems for the practical eigenvector free methods of Gay and Goerisch are obtained under a variety of hypotheses, so that our theorems apply to both traditional boundary-value problems and atomic problems. ...

#### Robust optimal switching control for nonlinear systems

(Siam Publications, 2002-09)

We formulate a robust optimal control problem for a general nonlinear system with finitely many admissible control settings and with costs assigned to switching of controls. e formulate the problem both in an L-2-gain/dissipative ...

#### Analysis and approximation of the velocity tracking problem for Navier-Stokes flows with distributed control

(Siam Publications, 2000-05)

We consider the mathematical formulation, analysis, and the numerical solution of a time-dependent optimal control problem associated with the tracking of the velocity of a Navier-Stokes ow in a bounded two-dimensional ...

#### An elementary nonlinear beam theory with finite buckling deformation properties

(Siam Publications, 2002-04)

A simple nonlinear beam model is derived from basic principles. The assumption upon which the derivation is based is that axial motions are of second order compared with transverse motions of the beam. The existence of ...
