We present various techniques to count proportions of permutations with restricted cycle structure in finite permutation groups. For example, we show how a generalized block theo...
Public-key cryptographic systems often involve raising elements of some group (e.g. GF(2n), Z/NZ, or elliptic curves) to large powers. An important question is how fast this expon...
In this paper it is our intention to discuss a Teacher Education proposal that uses an on line asynchronous learning environment to develop collaborative practices and to enhance ...
The calculation of salient structures is one of the early and basic ideas of perceptual organization in Computer Vision. Saliency algorithms typically mark edge-points with some s...
Knowledge of how people interact is important in many disciplines, e.g. organizational behavior, social network analysis, information diffusion and knowledge management applicatio...
