The Chow flag varieties are introduced and studied. In a family of pure dimensional projective complex varieties defined via Chow flag varieties, the isomorphism type of Lawson homology of a general member in the family is discussed. Applications to morphic cohomology and motivic cohomology on smooth projective complex varieties are discussed.

This document presents the detailed design of the two main defense approaches under development within the project MILTIADES, namely the IP address space randomiza-tion proactive defense technique against hit-list worms, and the emulation-based poly-morphic attack detection technique.

In this paper, we re-formulate “morphic cohomology” as introduced by the author and H.B. Lawson [F-L1] in such a way that it and “Lawson homology” satisfy the list of basic properties codified by S. Bloch and A. Ogus [B-O]. This reformulation enables us to clarify and unify our previous definitions and provides this topological cycle theory with foundational properties which have proved useful ...

A representational scheme under which the ranking between represented dissimilarities is iso-morphic to the ranking between the corresponding shape dissimilarities can support perfect shape classiication, because it preserves the clustering of shapes according to the natural kinds prevailing in the external world. We discuss the computational requirements of rank-preserving representation, and ...

In some particular cases we give criteria for morphic sequences to be almost periodic (=uniformly recurrent). Namely, we deal with fixed points of non-erasing morphisms and with automatic sequences. In both cases a polynomial-time algorithm solving the problem is found. A result more or less supporting the conjecture of decidability of the general problem is given.
