Rateless Codes for AVC Models

Michael Christoph Gastpar

The arbitrarily varying channel (AVC) is a channel model whose state is selected maliciously by an adversary. Fixed-blocklength coding assumes a worst-case bound on the adversary's capabilities, which leads to pessimistic results. This paper defines a vari ...

Inferring activities from context measurements using Bayesian inference and random utility models

Michel Bierlaire, Gunnar Flötteröd, Ricardo Daniel Hurtubia González

Smartphones collect a wealth of information about their users. This includes GPS tracks and the MAC addresses of devices around the user, and it can go as far as taking visual and acoustic samples of the user's environment. We present a framework to identi ...

Utilisation de PLSI en recherche d'information

Jean-Cédric Chappelier, Emmanuel Eckard

The PLSI model (“Probabilistic Latent Semantic Indexing”) offers a document indexing scheme based on probabilistic latent category models. It entailed applications in diverse ﬁelds, notably in information retrieval (IR). Nevertheless, PLSI cannot process d ...

Register File Reliability Analysis Through Cycle-Accurate Thermal Emulation

David Atienza Alonso, José Luis Ayala Rodrigo, Pablo Garcia del Valle

Continuous transistor scaling due to improvements in CMOS devices and manufacturing technologies is increasing processor power densities and temperatures; thus, creating challenges when trying to maintain manufacturing yield rates and devices which will be ...

A Dynamically Constrained Genetic Algorithm For Hardware-software Partitioning

Guillaume Zufferey, Pierre-André Mudry

In this article, we describe the application of an enhanced genetic algorithm to the problem of hardware-software codesign. Starting from a source code written in a high-level language our algorithm determines, using a dynamically-weighted fitness function ...

Synthesis and structure of Mu-33, a new layered aluminophosphate

Philip Pattison

Mu-33, a new layered aluminophosphate with an Al/P ratio of 0.66, was obtained from a quasi non-aqueous synthesis in which tert-butylformamide (tBF) was the main solvent and only limited amounts of water were present. During the synthesis, tBF decomposed a ...

Spatio-Temporal Shadow Segmentation and Tracking

Touradj Ebrahimi, Elena Salvador

Shadow segmentation is a critical issue for systems aiming at extracting, tracking or recognizing objects in a given scene. Shadows can in fact modify the shape and colour of objects and therefore affect scene analysis and interpretation systems in many ap ...

Ferritic/martensitic steels - overview of recent results

Considerable research work has been conducted on the ferritic/martensitic steels since the last International Conference on Fusion Reactor Materials in 1999. Since only a limited amount of that work can be reviewed in this paper, four areas will be emphasi ...

Regulation of adipocyte differentiation

Johan Auwerx

Once multipotent mesenchymal cells become committed to the adipoblast lineage, adipogenesis, the process of preadipocytes differentiation into adipocytes is initiated. This process starts with a phase of exponential growth of adipoblasts. Following conflue ...

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 ...
