Statistical Decision Making for Authentication and Intrusion Detection

Christos Dimitrakakis, Aikaterini Mitrokotsa

User authentication and intrusion detection differ from standard classification problems in that while we have data generated from legitimate users, impostor or intrusion data is scarce or non-existent. We review existing techniques for dealing with this p ...

Can bioactivity be tested in vitro with SBF solution ?

Jacques Lemaître

A large part of the scientiﬁc community has accepted the paradigm that a simulated body solution (SBF) can be used to test the bioactivity of a material. This is exempliﬁed by the rapidly increasing number of publications using this test. The aim of this d ...

Graphical display for annual climate-based daylight simulation

Marilyne Andersen, Magali Bodart

Due to daylight variability, a design cannot be thoroughly assessed using single-moment simulations, which is why we need dynamic performance metrics like Daylight Autonomy and Useful Daylight Illuminance. Going one step further, the annual variation in pe ...

Normalisation of Histogrammed List Mode Data

Many PET scanners nowadays have the possibility to record event-by-event information, known as list mode data. This has the advantage of keeping the data in the highest possible resolution (both temporal and spatial). In most cases, list mode data are then ...

Dynamic faceted search for discovery-driven analysis

Anastasia Ailamaki, Debabrata Dash

We propose a dynamic faceted search system for discovery-driven analysis on data with both textual content and structured attributes. From a keyword query, we want to dynamically select a small set of "interesting" attributes and present aggregates on them ...

Tools to evaluate future actions on the traffic in Lausanne

Michel Bierlaire

Lausanne-Morges agglomeration will experiment strong increases in the number of inhabitants and jobs until 2020. The additional trips generated by these increases will have to be carried out in a larger proportion by soft mobility and transit. There are ma ...

Adaptive processing over distributed networks

Ali H. Sayed

The article describes recent adaptive estimation algorithms over distributed networks. The algorithms rely on local collaborations and exploit the space-time structure of the data. Each node is allowed to communicate with its neighbors in order to exploit ...

Experiences with Reproducible Research in Various Facets of Signal Processing Research

Martin Vetterli, Andrea Ridolfi, Guillermo Barrenetxea Kobas, Ivana Jovanovic, Patrick Vandewalle

How often have you been able to implement an algorithm as it is described in a paper? And when you did, were you confident that you had exactly the same parameter values and results as the authors of the paper? All too often, articles do not describe all t ...

Solving Atomic Broadcast with Indirect Consensus

André Schiper, Nils Richard Ekwall

In previous work, it has been shown how to solve atomic broadcast by reduction to consensus on messages. While this solution is theoretically correct, it has its limitations in practice, since executing consensus on large messages can quickly saturate the ...
