Robustness

Stephan Morgenthaler

That the conclusion based on a data analysis be robust and stable is not merely a desirable feature, it is essential. To merit this quality label, a conclusion must be supported by strong data-based evidence and not simply be a discovery gleaned from a pre ...

A union of incoherent spaces model for classification

Pierre Vandergheynst, Karin Schnass

We present a new and computationally efficient scheme for classifying signals into a fixed number of known classes. We model classes as subspaces in which the corresponding data is well represented by a dictionary of features. In order to ensure low miscla ...

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 ...

On Data-Centric Trust Establishment in Ephemeral Ad Hoc Networks

Jean-Pierre Hubaux, Panagiotis Papadimitratos, Maxime Raya

We argue that the traditional notion of trust as a relation among entities, while useful, becomes insu±cient in ephemeral ad hoc networks. In this paper, we address the challenge of extending the traditional notion of trust to data-centric trust, that is, ...

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 ...

Comment on 'Critical behaviour in the relaminarization of localized turbulence in pipe flow'

Tobias Schneider, Jerry Westerweel

This is a comment on arXiv:physics/0608292, subsequently published in Phys Rev Lett, 98, 014501 (2007), in which Willis and Kerswell study in direct numerical simulations the statistics of turbulent lifetimes in pipe flow. They suggest that their data for ...

Pitfalls in Estimating the Returns to Corporate R&D Using Accounting Data

Dominique Foray

Does R&D have an impact on firm growth, profits, and value? To most observers, the obvious answer is yes. However, the recent report by Booz-Allen-Hamilton (BAH 2006) seems to conclude that the share of spending devoted to research has no relationship to t ...

Can we assess the model complexity for a bioprocess: theory and example of the anaerobic digestion process

Benoît Chachuat, Olivier Bernard

In this paper we propose a methodology to determine the structure of the pseudo-stoichiometric coefficient matrix K in a mass balance based model, i.e. the maximal number of biomasses that must be taken into account to reproduce an available data set. It c ...

Spreadsheet Framework for Visual Exploration of Biomedical Datasets

Daniel Thalmann, Ronan Boulic, Sofiane Sarni, Anderson Maciel

In this paper, we present our spreadsheet framework, which uses a spreadsheet-likeinterface for exploring biomedical datasets. The principles and advantages of this classof visualization systems are illustrated, and a case study for the analysis of hip joi ...
