On the distribution of the length of the longest increasing subsequence of random permutations
- J. Amer. Math. Soc
, 1999
"... Let SN be the group of permutations of 1, 2,...,N. If π ∈ SN,wesaythat π(i1),...,π(ik) is an increasing subsequence in π if i1 <i2 <·· · <ikand π(i1) < π(i2) < ···<π(ik). Let lN (π) be the length of the longest increasing subsequence. For example, if N =5andπis the permutation 5 1 ..."

Three-dimensional object recognition from single two-dimensional images
- Artificial Intelligence
, 1987
"... A computer vision system has been implemented that can recognize threedimensional objects from unknown viewpoints in single gray-scale images. Unlike most other approaches, the recognition is accomplished without any attempt to reconstruct depth information bottom-up from the visual input. Instead, ..."

, three other mechanisms are used that can bridge the gap between the two-dimensional image and knowledge of three-dimensional objects. First, a process of perceptual organization is used to form groupings and structures in the image that are likely to be invariant over a wide range of viewpoints. Second

Imprimitive Permutations Groups
"... We answer a question of Paterson, showing that all block systems for the group generated by the round functions of a key-alternating block cipher are the translates of a linear subspace. Following up remarks of Paterson and Shamir, we exhibit a connection to truncated di#erential cryptanalysis. ..."

Introduction and statement of results Finite primitive permutation groups of rank 3 have been the subject of much study in the past twenty years, leading on the one hand to interesting new groups (for instance, some sporadic groups) and on the other to new techniques in the theory of permutation gro ..."

ON TRANSITIVE PERMUTATION GROUPS WITH AN IMPRIMITIVITY BLOCK OF PRIME LENGTH
"... ABSTRACT. Let G be a transitive permutation group on a finite set 12. Let 23 ={A 1,A2,...,At) be a system of imprimitivity for G on 12 with [All = p, a prime. Assume that the kernel of G on 23 is not faithful on A 1. It is proved that either G contains a nontrivial normal elementary abelian p-subgro ..."
