Reliability of computational science

Fabio Nobile

Today's computers allow us to simulate large, complex physical problems. Many times the mathematical models describing such problems are based on a relatively small amount of available information such as experimental measurements. The question arises whet ...

Border Games in Cellular Networks

Jean-Pierre Hubaux, Mark Felegyhazi, Mario Cagalj, Diego Dufour

In each country today, cellular networks operate on carefully separated frequency bands. This separation is imposed by the regulators of the given country to avoid interference between these networks. But, the separation is only valid within the borders of ...

A tutorial on (Bayesian) probability

Claudio Mattiussi

The aim of this tutorial is to show that, when properly formulated, probability theory is simply the science of plausible reasoning, which permits us to represent exactly and to update our state of information about the world. This is nothing new, since in ...

On Selfish Behavior in CSMA/CA Networks

Jean-Pierre Hubaux, Imad Aad, Mario Cagalj

CSMA/CA protocols rely on the random deferment of packet transmissions. Like most other protocols, CSMA/CA was designed with the assumption that the nodes would play by the rules. This can be dangerous, since the nodes themselves control their random defer ...

Correlation between modulation and structural disorder in the 4,4 '-diethoxyazoxybenzene

Gervais Chapuis, Philip Pattison

The structural refinement of the modulated phase of 4,4'-Diethoxyazoxybenzene (DXB) indicates a correlation between the shifts on the DXB molecule (modulation) and the probability to find the azoxy (N --> O) group in different configurations (disorder). Th ...

Gracefully Degrading Fair Exchange with Security Modules

Rachid Guerraoui, Gildas Avoine

The fair exchange problem is key to trading electronic items in systems of mutually untrusted parties. In modern variants of such systems, each party is equipped with a tamper proof security module. The security modules trust each other but can only commun ...

Reliability and latency in binary communication

Emre Telatar, Aslan Tchamkerten

The transmission of one of two messages over a binary symmetric channels with perfect and instantaneous feedback is considered. We study the situation where transmitter and receiver want to communicated reliably and quickly. We propose a simple decoding ru ...

A Dynamic Analysis of Takeover Deals with Competition and Imperfect Information

Erwan Morellec

This article develops an equilibrium framework for the joint determination of the timing and the terms of takeovers in the presence of competition and imperfect information. The model analyzes takeovers as exchange options and derives equilibrium restructu ...

Rational Exchange -- A Formal Model Based on Game Theory

Jean-Pierre Hubaux, Levente Buttyan

We introduce game theory as a formal framework in which exchange protocols can be modeled and their properties can be studied. We use this framework to give a formal definition for rational exchange relating it to the concept of Nash equilibrium in games. ...

On Hack's law

Andrea Rinaldo, Amos Maritan

Hack's law is reviewed, emphasizing its implications for the elongation of river basins as well as its connections with their fractal characteristics. The relation between Hack's law and the internal structure of river basins is investigated experimentally ...
