The influences of environmental conditions on source localisation using a single vertical array and their exploitation through ground effect inversion [PDF]

, 2010
The performance of microphone arrays outdoors is influenced by the environmental conditions. Numerical simulations indicate that, while horizontal arrays are hardly affected, direction-of-arrival (DOA) estimation with vertical arrays becomes biased in ...

Early detection and location of unexpected events in buried pipelines under unseen conditions using the two‐stream global fusion classifier model

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 21, Page 3295-3315, 29 August 2025.
Abstract Failure of buried pipelines can result in serious impacts, such as explosions, environmental contamination, and economic losses. Early detection and location of unexpected events is crucial to prevent such events. However, conventional monitoring methods exhibit limited generalization performance under varying environmental and operational ...

Leveraging Whole Genomes, Mitochondrial DNA and Haploblocks to Decipher Complex Demographic Histories: An Example From a Broadly Admixed Arctic Fish

Molecular Ecology, Volume 34, Issue 10, May 2025.
ABSTRACT The study of phylogeography has transitioned from mitochondrial haplotypes to genome‐wide analyses, borrowing from population genomics methods along the way. Whole‐genome sequencing allows the study of both mitochondrial and nuclear DNA and provides the density of markers to investigate recombination along the genome.

An experimental proof of concept of time‐reversal single‐sensor acoustic source localisation: Application to partial discharges

High Voltage, Volume 10, Issue 2, Page 351-361, April 2025.
Abstract In this paper, for the first time, an experimental proof of concept for utilising time reversal (TR) in the acoustic regime to localise partial discharge (PD) sources was presented using a single sensor. To achieve this, an experimental setup comprising a water tank, acoustic transducers for signal transmission and reception, and 2D scanners ...

A population Monte Carlo model for underwater acoustic telemetry positioning in reflective environments

Methods in Ecology and Evolution, Volume 16, Issue 4, Page 775-785, April 2025.
Abstract Underwater acoustic telemetry positioning is widely used to track the fine‐scale movements of aquatic animals. In study areas near acoustically reflective surfaces, reflected transmissions may cause large detection outliers that can severely reduce the accuracy of positioning models.

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

Biological 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

Reflection-Aware Sound Source Localization

, 2017
We present a novel, reflection-aware method for 3D sound localization in indoor environments. Unlike prior approaches, which are mainly based on continuous sound signals from a stationary source, our formulation is designed to localize the position ...

Emitter Location Finding using Particle Swarm Optimization [PDF]

, 2014
Using several spatially separated receivers, nowadays positioning techniques, which are implemented to determine the location of the transmitter, are often required for several important disciplines such as military, security, medical, and commercial ...
