The Space Complexity of Approximating the Frequency Moments
The frequency moments of a sequence containing mi elements of type i, for 1 i n, are the numbers Fk = n i=1 mk i . We consider the space complexity of randomized algorithms that...

Fingerprint images encryption via multi-scroll chaotic attractors
This paper proposes a chaotic fingerprint images encryption approach. An image of a fingerprint is encrypted via a twodimensional (2D) chaotic sequence obtained from multi-scrol...

Bounds on the distribution of the number of gaps when circles and lines are covered by fragments: Theory and practical applicati
Background: The question of how a circle or line segment becomes covered when random arcs are marked off has arisen repeatedly in bioinformatics. The number of uncovered gaps is o...

Guessing Revisited: A Large Deviations Approach
The problem of guessing a random string is revisited and some prior results on guessing exponents are re-derived using the theory of large deviations. It is shown that if the seque...
