Automatic detection for bioacoustic research: a practical guide from and for biologists and computer scientists

open access: yesBiological Reviews, Volume 100, Issue 2, Page 620-646, April 2025.
ABSTRACT Recent years have seen a dramatic rise in the use of passive acoustic monitoring (PAM) for biological and ecological applications, and a corresponding increase in the volume of data generated. However, data sets are often becoming so sizable that analysing them manually is increasingly burdensome and unrealistic. Fortunately, we have also seen

Customer Segmentation through Path Reconstruction

open access: yesSensors, 2021
This paper deals with the automatic classification of customers on the basis of their movements around a sports shop center. We start by collecting coordinates from customers while they visit the store.

Multi-mode Tracking of a Group of Mobile Agents

open access: yes, 2017
We consider the problem of tracking a group of mobile nodes with limited available computational and energy resources given noisy RSSI measurements and position estimates from group members.

Separation of SSR signals by array processing in multilateration systems [PDF]

open access: yes, 2009
Location and identification of cooperating aircraft in the airport area (and beyond) may be implemented by multilateration (MLAT) systems using the secondary surveillance radar (SSR) mode S signals.

Movement in 3D: Novel Opportunities for Understanding Animal Behaviour and Space Use

open access: yesEthology, Volume 131, Issue 3, March 2025.
ABSTRACT Animals move in three spatial dimensions, but many animal movement tools have only focused on the use of 2D coordinates for modelling space use, habitat selection, behavioural classification, social interactions and movement. Here, we submit that many common movement ecology analyses can and should be extended to consider all three spatial ...

Modified Bancroft Algorithm for Multilateration Systems

open access: yesИзвестия высших учебных заведений России: Радиоэлектроника, 2018
In multilateration systems, Bancroft algorithm is often used to estimate the location of objects. This algorithm is synthesized for satellite navigation systems.

Access Point Selection and Localization for Cluster‐Based Realization of a Device‐to‐Device Cell‐Free 6G Communications Network

open access: yesIET Communications, Volume 19, Issue 1, January/December 2025.
We introduce a fully distributed framework that leverages belief‐desire‐intention extended (BDIx) agents on user devices to perform dynamic clustering and access‐point selection in a cell‐free 6G network, using both classical and deep‐learning methods for deterministic, scalable AP grouping.

Underwater Localization via Wideband Direction-of-Arrival Estimation Using Acoustic Arrays of Arbitrary Shape

open access: yesSensors, 2020
Underwater sensing and remote telemetry tasks necessitate the accurate geo-location of sensor data series, which often requires underwater acoustic arrays. These are ensembles of hydrophones that can be jointly operated in order to, e.g., direct acoustic

Underwater Positioning System Based on Drifting Buoys and Acoustic Modems

open access: yesJournal of Marine Science and Engineering, 2023
GNSS (Global Navigation Satellite System) positioning is not available underwater due to the very short range of electromagnetic waves in the sea water medium.

Aerial Anchors Positioning for Reliable RSS-Based Outdoor Localization in Urban Environments

open access: yes, 2017
In this letter, the localization of terrestrial nodes when unmanned aerial vehicles (UAVs) are used as base stations is investigated. Particularly, a novel localization scenario based on received signal strength (RSS) from terrestrial nodes is introduced.
