Optimistic atomic broadcast: a pragmatic viewpoint

André Schiper, Fernando Pedone

Optimistic atomic broadcast: a pragmatic viewpoint F.Pedone and A.Schiper This paper presents the Optimistic Atomic Broadcast algorithm (OPT-ABcast) which exploits the spontaneous total-order property experienced in local-area networks in order to allow fa ...

Fusion of competing features is not serial

Michael Herzog

How features of an object are bound into a unique percept is one of the puzzling problems in the cognitive and neuro-sciences. In order to investigate the spatio-temporal mechanisms of feature binding, we serially present two verniers with opposite offset ...

Extending Kubelka-Munk's Theory with Lateral Light Scattering

Roger Hersch, Patrick Emmel, Safer Mourad

Due to its simplicity, the theory of KUBELKA-MUNK [1] has found a wide acceptance for modeling the optical properties of light scattering materials. However, the concept is not explicitly adapted to predict halftone prints on paper. In this respect, a rece ...

Higher Order Autocorrelations for Pattern Classification

Jean-Philippe Thiran, Vlad Popovici

The use of higher-order local autocorrelations as features forpattern recognition has been acknowledge since many years, but their applicability was restricted to relatively low orders (2 or 3) and small local neighborhoods, due to combinatorial increase i ...

Mechanical properties of individual microtubules measured using atomic force microscopy

László Forró, Giovanni Dietler, Andras Kis, Andrzej Kulik, Sandor Kasas

Atomic force microscopy has been used to investigate the mechanical properties of microtubules. Method of Salvetat et al. [1], originally developed for measuring the Young's modulus of carbon nanotubes, has been extended to a biological system of similar g ...

Adaptation robuste de modeles HMM pour la verification du locuteur dependante du texte

When deploying a secure system based on speaker verification, the limited amount of training data is usually critical. Indeed, the enrollment procedure must be fast and user-friendly. An incremental training of HMM speaker models, based on a MAP (Maximum A ...

Topology of the Fittest Transportation Network

Andrea Rinaldo, Amos Maritan

The presence or absence of loops in the emergent transportation networks, that are characterized by a minimum overall cost, is shown to depend on the convexity of the cost function for the local transportation of material. Our results are directly applicab ...

Geometrical Behaviours: An Architectural Mise-en-scène for a Reenactment of Lewis Carroll's Alice's Adventures in Wonderland

Caroline Dionne

The content of this thesis is two-fold. The first part takes the form of an essay while the second part presents a theoretical project for an architectural installation. Using these two modes as different ways to address similar issues, the present work pr ...

Direct 3D interaction with Smart Objects

Daniel Thalmann

Performing 3D interactions with virtual objects easily becomes a complex task, limiting the implementation of larger applications. In order to overcome some of these limitations, the paper describes a framework where the virtual object aids the user to acc ...

Introducing Trusted Third Parties to the Mobile Agent Paradigm

Uwe Wilhelm

Systems that support mobile agents are increasingly being used on the global Internet. An important application that is considered for these agents is electronic commerce, where agents roam the World Wide Web in search of goods for their owners. In these a ...
