Multicast is rapidly becoming an important mode of communication and a good platform for building group-oriented services. To be used for trusted communication , however, current multicast schemes must be supplemented by mechanisms for protecting traac, controlling participation, and restricting access of unauthorized users to data exchanged by the participants. In this paper, we consider funda...

In CSL’99 Roversi pointed out that the Turing machine encoding of Girard’s seminal paper ”Light Linear Logic” has a flaw. Moreover he presented a working version of the encoding in Light Affine Logic, but not in Light Linear Logic. In this paper we present a working version of the encoding in Light Linear Logic. The idea of the encoding is based on a remark of Girard’s tutorial paper on Linear ...

The Internet has made great success and big progress. However, the network-layer of Internet and the network devices in Internet have been relatively stagnant. Few changes or improvements have been made in last forty years, which is a stark contrast to the prosperity of the application-layer of the Internet. OpenFlow aims to enable innovation for the network-layer and network devices, which dec...

This paper presents a linear representation of the built environment called “continuity line”. A continuity line is the aggregation of several axial lines to represent an urban path in its longest extension, respecting a maximum sinuosity previously defined. It is based on two main arguments: first, that the notion of continuity is already embedded in the axial system; and second, that the cont...

We investigate a variant of the Beurling-Ahlfors extension quasisymmetric homeomorphisms real line that is given by convolution heat kernel, and prove complex dilatation such quasiconformal strongly symmetric homeomorphism (i.e. its derivative an ${\rm A}_\infty$-weight whose logarithm in VMO) induces vanishing Carleson measure on upper half-plane.

We introduce super Yangian double DYh̄[gl(m|n)] and its central extension ̂ DYh̄[gl(m|n)]. We give their defining relations in terms of current generators and obtain Drinfeld comultiplication. Queen Elizabeth II Fellow; Email: [email protected] This paper concerns with Drinfeld current realization [1] of super Yangian double DYh̄[gl(m|n)] and its central extension ̂ DYh̄[gl(m|n)]. The Yangian doubl...

In this Letter we have proposed a point particle model that generates a noncommutative three-space, with the coordinate brackets being Lie algebraic in nature, in particular isomorphic to the angular momentum algebra. The work is in the spirit of our earlier works in this connection, i.e. PLB 618 (2005)243 and PLB 623 (2005)251, where the κ-Minkowski form of noncomutative spacetime was consider...

In this paper, a novel extension neural network (ENN) is proposed. This new neural network is a combination of extension theory and neural network. It uses an extension distance (ED) to measure the similarity between data and cluster center. The learning speed of the proposed ENN is shown to be faster than the traditional neural networks and other fuzzy classification methods. Moreover, the new...
