Using semi-open questions to integrate perceptions in choice models

Michel Bierlaire, Aurélie Glerum, Bilge Atasoy

This research investigates the measurement of perceptions by means of adjectives freely reported by respondents in semi-open questions. The objective of this work is to use these adjectives as indicators of perceptions in hybrid choice models (HCM) in orde ...

Cost-efficient and Differentiated Data Availability Guarantees in Data Clouds

Karl Aberer, Nicolas Bonvin

Failures of any type are common in current datacenters. As data scales up, its availability becomes more complex, while different availability levels per application or per data item may be required. In this paper, we propose a self- managed key-value stor ...

Effect of replica placement on the reliability of large scale data storage systems

Christina Fragouli, Vinodh Venkatesan, Xiao-Yu Hu, Robert Haas

Replication is a widely used method to protect large- scale data storage systems from data loss when storage nodes fail. It is well known that the placement of replicas of the different data blocks across the nodes affects the time to rebuild. Several syst ...

Phantm: PHP Analyzer for Type Mismatch

Viktor Kuncak, Etienne Kneuss, Philippe Paul Henri Suter

We present Phantm, a static analyzer that uses a flow-sensitive analysis to detect type errors in PHP applications. Phantm can infer types for nested arrays, and can leverage runtime information and procedure summaries for more precise results. Phantm foun ...

ELM filament interaction with the JET main chamber☆

Richard Pitts, Gilles Arnoux

This work constitutes the first extended analysis of the spatial structure of Type-I ELM filament footprints on the JET outer limiters and upper dump plates. The data is obtained using a wide angle infrared diagnostic (with time resolution of 125 Hz) and c ...

Hierarchical diffusion algorithms for distributed estimation

Ali H. Sayed

We study the problem of distributed estimation, where a set of nodes are required to collectively estimate some parameter of interest from their measurements. Distributed implementations avoid the use of a fusion center and distribute the processing and co ...

Dynamic Cost-Efficient Replication in Data Clouds

Karl Aberer, Nicolas Bonvin

Hardware failures in current data centers are common partly due to the higher data scales supported. Data replication is the common approach for improving availability. However, mostly static replication approaches have been proposed, i.e. the number of re ...

Culture and Development

Harry Gugger

Presentation at the International symposium on Museums of the Future, which was organized for the presentation of the first draft of KMoMA. The presentaiton outlined the approach that cultural institutions can be civic, social, and cultural cornerstones fo ...

An Economic Model for Self-tuned Cloud Caching

Anastasia Ailamaki, Debabrata Dash

Cloud computing, the new trend for service infrastructures requires user multi-tenancy as well as minimal capital expenditure. In a cloud that services large amounts of data that are massively collected and queried, such as scientific data, users typically ...
