Wideband beam domain sparse Bayesian learning passive focusing localisation algorithm

IET Radar, Sonar & Navigation
To address the challenges of large‐aperture sonar systems passive localisation, this paper proposes the application of sparse Bayesian learning (SBL) for passive target localisation in the wideband beam domain. The proposed algorithm aims to overcome the

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Bionic covert anti-reverberation active sonar detection method based on imitating whale whistles

Journal of Measurement Science and Instrumentation, 2022
The disguised covert detection method that imitates whale calls has received great attention in recent years because it can solve the traditional problem of the trade-off between long-range detection and covert detection.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

Sonar, Acoustic Wave Propagation, and Signal Processing

, 2022
Sonar systems are the primary means by which we image or gain understanding of underwater environments. In contrast to more familiar remote sensing apparatuses such as radar or cameras, sonar systems rely on the propagation of mechanical, pressure waves ...

Diffusion Coefficient and Viscosity of Methyl Viologen Electrolyte Estimation Based on a Kinetic Monte Carlo Computational Approach Coupled with the Mean Square Displacement Method

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A novel and comprehensive 3D‐resolved kinetic Monte Carlo model coupled with mean square displacement analysis is introduced. This computational approach allows to explore, for the first time, the concentration and the state of charge effects on ionic diffusion coefficient and viscosity in methyl viologen‐based electrolytes used in organic redox flow ...

The Multifaceted Role of Trust in Circular Ecosystems: A Systematic Literature Review and Research Agenda

Business Strategy and the Environment, EarlyView.
ABSTRACT Circular ecosystems connect diverse actors who collaborate to close resource loops and pursue sustainable goals without centralized control. Such arrangements entail heightened interdependence and uncertainty, making trust, understood as the willingness to accept vulnerability based on positive expectations of others' behavior, a critical ...
