Image De-Quantizing via Enforcing Sparseness in Overcomplete Representations
We describe a method for removing quantization artifacts (de-quantizing) in the image domain, by enforcing a high degree of sparseness in its representation with an overcomplete or...

Direction-Dependency of a Binary Tomographic Reconstruction Algorithm
We study how the quality of an image reconstructed by a binary tomographic algorithm depends on the direction of the observed object in the scanner, if only a few projections are a...

Online Function Tracking with Generalized Penalties
We attend to the classic setting where an observer needs to inform a tracker about an arbitrary time varying function f : N0 → Z. This is an optimization problem, where both wron...

Finding All Gravitationally Stable Orientations of Assemblies
Previous work by Mattikalli et al.[1] considered the stability of assemblies of frictionless contacting bodies with uniform gravity. A linear programming-based technique was descr...

The Space of EDF Feasible Deadlines
It is well known that the performance of computer controlled systems is heavily affected by delays and jitter occurring in the control loops, which are mainly caused by the interf...
