Moderation in virtual communities should not be a private privilege. This paper proposes a method for participants in a social network to decide their own rules for accepting (or not) contents. With the norm argument map, participants are able to argue about norms and voice their opinions about other people?s arguments. This structure, equipped with a method to fuse all the data introduced by p...

We present a method for painting texture maps directly onto trimmed NURBS models using a haptic interface. The haptic interface enables an artist to use a natural painting style while creating a texture. It avoids the traditional difficulty of mapping between the 2D texture space and the 3D model space by using parametric information available from our haptic tracing algorithm. The system maps ...

(1) Give a purely combinatorial definition of the Floer cochain complex (CF (L0, L1), ∂) over ΛZ2 . In particular, prove that ∂ 2 = 0. (2) Now do the same, but over ΛK where K is an arbitrary field (not necessarily of characteristic 2). (3) How far can the conditions on the Li be relaxed? Can they be immersed curves, or nullhomotopic curves? (4) More generally, let L0, . . . , Lk be transversel...

It is a well-known result of Kadec that every two separable infinite dimensional Banach spaces are homeomorphic. Also in large classes of nonseparable Banach spaces (perhaps all) the density character of a Banach space is its only topological invariant (see the book [2] for details). The situation changes considerably if we consider uniform homeomorphisms. Several results are known which prove ...

This paper describes the problem of locating terminals using E.164 numbers, and the problem of selecting a suitable gateway for calls from an IP telephony network to the public switched telephone network (PSTN). Generally, these are the problems of mapping the name of a destination into an address, and to find the best route to the destination in a combined IP and PSTN network. Number portabili...

This paper revisits the little-known Gibbs-Rodrigues representation of rotations in a three-dimensional space and demonstrates a set of algorithms for handling it. In this representation the rotation is itself represented as a three-dimensional vector. The vector is parallel to the axis of rotation and its three components transform covariantly on change of coordinates. The mapping from rotatio...
