Image filtering: Potential efficiency and current problems
The paper contains comparisons of lower bound (potential) and achieved efficiency for filtering grayscale and color images corrupted by AWGN. It is demonstrated that for complex s...

Sampling signals with finite rate of innovation in the presence of noise
Recently, it has been shown that it is possible to sample non-bandlimited signals that possess a limited number of degrees of freedom and uniquely reconstruct them from a finite ...

Fundamental limitations of continuous-time delta-sigma modulators due to clock jitter
We examine noise due to clock jitter in single-loop low pass continuous-time delta-sigma modulators employing NRZ feedback DACs. Using the discrete-time version of the Bode sensit...

The Quantum Query Complexity of Algebraic Properties
We present quantum query complexity bounds for testing algebraic properties. For a set S and a binary operation on S, we consider the decision problem whether S is a semigroup or ...

Multi-Objective Propagation in Constraint Programming
Bounding constraints are used to bound the tolerance of solutions under certain undesirable features. Standard solvers propagate them one by one. Often times, it is easy to satisfy...
