An efficient auxiliary variable method for quantification of spin density, R2* decay and field inhomogeneity maps in magnetic resonance imaging
(2015-04-07)
Quantification of spin density, $R_2^*$ decay and off-resonance frequency maps is very important in some applications of magnetic resonance imaging (MRI). To reconstruct these parameter maps, a time-varying model such as ...
Trust region methods for estimation of a complex exponential decay model in MRI with a single-shot or multi-shot trajectory (in review)
(2015-05-05)
Joint estimation of spin density, R2* decay and off-resonance frequency maps is very useful in many magnetic resonance imaging (MRI) applications. The standard multi-echo approach can achieve high accuracy but requires a ...
Characterization of Plenoptic Imaging Systems and Efficient Volumetric Estimation from Plenoptic Data
(2015-01-13)
Plenoptic imaging is a rapidly growing field driven
by the ever-declining cost of imaging systems and the promise
of image focus, perspective, and depth of field manipulation
during post-processing. While plenoptic ...
A Solution of Rigid Perfectly Plastic Deep Spherical Indentation based on Slip Line Theory
(2015-11-16)
During indentation it is often important to determine the relationship between the average pressure and the yield strength. This work uses slip line theory to determine this relationship for the case of a rigid sphere ...
