Given a lattice polytope Q ⊆ IR, we define an affine scheme M̄ that reflects the possibilities of splitting Q into a Minkowski sum. On the other hand, Q induces a toric Gorenstein singularity Y , and we construct a flat family over M̄ with Y as special fiber. In case Y has an isolated singularity only, this family is versal.

despite possessing the adequate purchase potential for the fast moving consumer goods (fmcgs), the poor are not reckoned as a viable market by the fmcg marketers and as a result, the purchase preferences of poor are largely unexplored for the concerned products. the present paper bridges the gap subsisting in the pertinent literature by exploring the purchase behavior of poor consumers in the r...

This paper discusses the visual algebraic speciication (vas) formalism and its supporting interactive environment (vase). The vas formalism is intended for the deenition of visual syntax and semantics and is aimed at generating language speciic environments. The collection construct of vas is emphasized in that it supports the convenient speciication of language constructs involving arbitrarily...

With the growth of its popularity, VoIP is increasingly popular nowadays. Similarly to other Internet applications, VoIP users may desire to be unlinkable with their participated VoIP session records for privacy issues. In this paper, we explore the Items of Interests (IOIs) from anonymisation aspects based on a simplified VoIP model and analyse the potential links between them. We address poss...

We consider the problem of listing faces of the Minkowski sum of several V-polytopes in R. An algorithm for listing all faces of dimension up to j is presented, for any given 0 ≤ j ≤ d − 1. It runs in time polynomial in the sizes of input and output.

This document specifies PT-TLS, a TLS-based Posture Transport (PT) protocol. The PT-TLS protocol carries the Network Endpoint Assessment (NEA) message exchange under the protection of a Transport Layer Security (TLS) secured tunnel.

In this paper, we evaluate the effects of monetary policy on inflation and unemployment under different institutional arrangements in the labor market. We show that the effects of monetary policy on the real economy depend critically on the wage formation regime, and on the ways in which the restrictiveness of policy interacts with product price competition, wage setting centralization and the ...
