Fractional-order correntropy adaptive filters for distributed processing of alpha-stable signals
(Peer reviewed; Journal article, 2020)This work revisits the problem of distributed adaptive filtering in multi-agent sensor networks. In contrast to classical approaches, the formulation relaxes the Gaussian assumption on the signal and noise to the generalized ... -
Comparing sound emergence and sound pressure level as predictors of short-term annoyance from wind turbine noise
(Journal article, 2020)While most of the countries over the world rely on sound-pressure-level-based limit values to regulate wind energy development, sound emergence as defined in ISO 1996-1 is used in a few national legislations but also in ... -
Subsea Oil Spill Risk Management Based on Sensor Networks
(Peer reviewed; Journal article, 2020)The use of Wireless Sensor Networks (WSNs) in support of Dynamic Risk Assessment regarding oil spills still lacks a proper integration. WSNs enable prompt responses to such emergencies through an appropriate inspection, ... -
Optimal Scheduling Policy for Spatio-temporally Dependent Observations using Age-of-Information
(Chapter, 2020)This paper proposes an optimal scheduling policy for a remote estimation problem, where sensor observations of two spatio-temporally correlated processes are broadcasted to two remote estimators. At each time instant only ... -
