Modelling natural disturbances in forest ecosystems: a review

Natural disturbances play a key role in ecosystem dynamics and are important factors for sustainable forest ecosystem management. Quantitative models are frequently employed to tackle the complexities associated with disturbance processes. Here we review t ...

Rate-Distortion Curve Evaluation for Cross-Layer Optimization in Progressive Video Transmission

Laura Toni

Robust streaming of video over wireless networks poses many challenges, as coping with bandwidth variations, data losses, and heterogeneity of the receivers. Rate-distortion (RD) optimization studies are aimed at increasing the reliability of received bits ...

Towards an improved understanding of farmers' behaviour: The integrative agent-centred (IAC) framework

Claudia Rebeca Binder Signer

An effective approach to research on farmers' behaviour is based on: i) an explicit and well-motivated behavioural theory; ii) an integrative approach; and iii) understanding feedback processes and dynamics. While current approaches may effectively tackle ...

Label-free Sorting and Counting of Yeast Cells for Viability Studies

Philippe Renaud, Niccolo Piacentini, Raphaël Tornay, Nina Buffi

This paper reports the new combination of cell sorting and counting capabilities on a single device. Most state-of-the-art devices combining these technologies use optical techniques requiring complicate experimental setups and labeled samples. The use of ...

Activity Level of an Atrial Ectopic Focus Observed Through the Equivalent Dipole: a Biophysical Model

Jean-Marc Vesin, Mathieu Lemay, Cédric Duchene, Vincent Jacquemet

Quantifying the role of atrial ectopic foci in the initiation and the maintenance of atrial fibrillation (AF) is a relevant clinical problem. This study aims at assessing the relation between the activity level of an ectopic focus and the complexity of the ...

Identity Aware Sensor Networks

Christina Fragouli, Suhas Diggavi, Lorenzo Keller, Mahdi Jafari Siavoshani

In a significant class of sensor-network applications, the identities of the reporting sensors are an essential part of the reported information. For instance, in environmental monitoring, the goal is to reconstruct physical quantities over space and time; ...

SimFlex: Statistical Sampling of Computer System Simulation

Anastasia Ailamaki, Babak Falsafi, Michael Ferdman

Timing-accurate full-system multiprocessor simulations can take years because of architecture and application complexity. Statistical sampling makes simulation-based studies feasible by providing ten-thousand-fold reductions in simulation runtime and enabl ...

Juicer: A Weighted Finite-State Transducer speech decoder

John David Scott Dines, Darren Moore

A major component in the development of any speech recognition system is the decoder. As task complexities and, consequently, system complexities have continued to increase the decoding problem has become an increasingly significant component in the overal ...
