The European emission trading scheme (EU ETS) has introduced a price for carbon and has thus led to an additional cost for companies that are regulated by the scheme. There is a growing body of empirical literature that investigates the effects of the EU ETS on firm eco...

The question to be addressed here is that of the agglomeration/dispersion forces that are likely to account for the location of people and jobs in rural areas and the way they explain spatial patterns in rural areas depending on urban influence. Economic geography model...

To optimize energy efficiency in network, operators try to switch off as many network devices as possible. Recently, there is a trend to introduce content caches as an inherent capacity of network equipment, with the objective of improving the efficiency of content dist...

In this paper, we prove that the two avours of well-compo- sedness called Continuous Well-Composedness (shortly CWCness), stat- ing that the boundary of the continuous analog of a discrete set is a manifold, and Digital Well-Composedness (shortly DWCness), stating that ...

Abstract A routing R of a connected graph G is a collection that contains simple paths connecting every ordered pair of vertices in G. The edge-forwarding index with respect to R (or simply the forwarding index with respect to R) π ( G , R ) of G is the maximum number o...

Passwords are still the most widespread means for authenticating users, even though they have been shown to create huge security problems. This motivated the use of additional authentication mechanisms in so-called multi-factor authentication protocols. In this article...

A transition in a graph is a pair of adjacent edges. Given a graph $$G=V,E$$, a set of forbidden transitions $$\mathcal{F}\subseteq E\times E$$ and two vertices $$s,t \in V$$, we study the problem of finding a path from s to t which uses none of the forbidden transition...

Abstract - We construct new functional encryption schemes that combine the access control functionality of attribute based encryption with the possibility of performing linear operations on the encrypted data. While such a primitive could be easily realized from fully f...

International audience; Remote electronic voting is used in several countries for legally binding elections. Unlike academic voting protocols, these systems are not always documented and their security is rarely analysed rigorously. In this paper, we study a voting syst...

International audience; Gabriel Tarde est un auteur français que la sociologie redécouvre de manière récurrente. Les économistes de l’innovation se sont insuffisamment intéressés à un auteur qui a pourtant consacré une grande partie de son œuvre aux lois de l’imitation ...
