Correction of Left Ventricle Strain Signals Estimated from Tagged MR Images
Strain measurement is a quantity used for assessing the regional function of the left ventricular (LV) of the heart. They are computed by tracking the motion of the non-invasive, ...

Iteratively reweighted algorithms for compressive sensing
The theory of compressive sensing has shown that sparse signals can be reconstructed exactly from many fewer measurements than traditionally believed necessary. In [1], it was sho...

Focuss is a convex-concave procedure
We show the powerful sparse signal recovery approach FOCUSS is a convex-concave procedure. It follows a Newton-like decent direction by retaining the positive definite component ...

Test Pattern Generation for Signal Integrity Faults on Long Interconnects
In this paper, we present a test pattern generation algorithm aiming at signal integrity faults on long interconnects. This is achieved by considering the effect of inputs and par...
