Hill's Equation with Random Forcing Terms
Motivated by a class of orbit problems in astrophysics, this paper considers solutions to Hill's equation with forcing strength parameters that vary from cycle to cycle. The ...

An Asymptotic Factorization Method for Inverse Electromagnetic Scattering in Layered Media
We investigate the performance of a MUSIC-type algorithm for low frequent time-harmonic electromagnetic imaging of the subsurface. This algorithm is based on an asymptotic analysis...

A straight line detection using principal component analysis
A straight line detection algorithm is presented. The algorithm separates row and column edges from edge image using their primitive shapes. The edges are labeled, and the princip...

Mixed Multiscale Finite Element Methods for Stochastic Porous Media Flows
In this paper, we propose a stochastic mixed multiscale finite element method. The proposed method solves the stochastic porous media flow equation on the coarse grid using a set ...

On characterizations of truthful mechanisms for combinatorial auctions and scheduling
We characterize truthful mechanisms in two multi-parameter domains. The first characterization shows that every mechanism for combinatorial auctions with two subadditive bidders t...
