Analysis and Computation of Compatible Least-Squares Methods for div-curl Equations
We develop and analyze least-squares finite element methods for two complementary div-curl elliptic boundary value problems. The first one prescribes the tangential component of ...

Direction-resolved estimation of multipath parameters for UWB channels: A partially collapsed Gibbs sampler method
We propose a Monte Carlo method for determining the parameters of multipath components (MPCs) for ultra-wideband channels. A partially collapsed Gibbs sampler is used for jointly ...

A Restoration and Extrapolation Iterative Method for Band-limited Fluorescence Microscopy Image
Optical microscopic images, especially with a nonconfocal microscope, are fundamentally limited because the optical transfer function (the Fourier transform of the point-spread fu...

Robust optimization based backtrace method for analog circuits
In this paper, we propose a new robust approach to signal backtrace for efficiently testing embedded analog modules in a large system. The proposed signal backtrace method is form...
