MilliKelvin resolution in cryogenic temperature distributed fibre sensing based on coherent Rayleigh scattering

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Xin Lu

The response of a distributed temperature sensor based on coherent Rayleigh scattering is experimentally studied in the temperature range from 77 K up to 300 K, using fibres with standard and ORMOCER coating. A precise and absolute frequency scan is perfor ...

Are ACT's scores increasing with better translation quality?

This paper gives a detailed description of the ACT (Accuracy of Connective Translation) metric, a reference-based metric that assesses only connective translations. ACT relies on automatic word-level alignment (using GIZA++) between a source sentence and r ...

Compressive-shear adhesion characterization of polyvinyl-butyral and ethylene-vinyl acetate at different curing times before and after exposure to damp-heat conditions

Christophe Ballif, Hengyu Li, Laure-Emmanuelle Perret Aebi, Valentin Chapuis

Photovoltaic (PV) module efficiency and reliability are two factors that have an important impact on the final cost of the PV electricity production. It is widely accepted that a good adhesion between the encapsulant and the different substrates of a PV mo ...

Reputation-based Estimation of Individual Performance in Collaborative and Competitive Grids

Hidden information is a critical issue for the successful delivery of services in grid systems. It arises when the agents (hardware and software resources) employed to serve a task belong to multiple administrative domains, thus rendering monitoring of rem ...

Solar Heat Surplus and Solar Heat Scarcity: the Inclusion of Solar Heat Gain in a Dynamic and Holistic Daylight Analysis

Marilyne Andersen

Solar heat gain is one of the tradeoffs associated with using natural light, and should be considered in any complete daylighting analysis. Because the non-spatial aspect of solar heat gain makes it more difficult to analyze along side illuminance or glare ...

Sparse Component Analysis for Speech Recognition in Multi-Speaker Environment

Hervé Bourlard, Philip Neil Garner, Afsaneh Asaei

Sparse Component Analysis is a relatively young technique that relies upon a representation of signal occupying only a small part of a larger space. Mixtures of sparse components are disjoint in that space. As a particular application of sparsity of speech ...

On the Optimal Placement of Mix Zones

Jean-Pierre Hubaux, Julien Freudiger, Reza Shokri

In mobile wireless networks, third parties can track the location of mobile nodes by monitoring the pseudonyms used for identification. A frequently proposed solution to protect the location privacy of mobile nodes suggests to change pseudonyms in regions ...

PathScore-Relevance: A Metric for Improving Test Quality

George Candea, Silviu Andrica

Reliability of today's software systems hinges on developers writing test cases that exercise as much of a program as possible. Writing and running such tests is inevitably subject to a time budget. This paper addresses the question of how to maximize qual ...

Deducing Ink Thickness Variations by a Spectral Prediction Model

Roger Hersch, Thomas Bugnon, Mathieu Brichon, Peter Amrhyn, Safer Mourad, Frédérique Crété

Most existing techniques for regulating the ink flow in offset presses rely oil density measurements carried out oil specially printed patches. In the present contribution. we develop a methodology to deduce ink thickness variations from spectral measureme ...

Toward Quantifying System Manageability

George Candea

Manageability directly influences a system's reliability, availability, security, and safety, thus being a key ingredient of system dependability. Alas, we do not have today a good way to measure manageability or reason quantitatively about it, and this is ...
