Remote Sensing in Ecology and Conservation, EarlyView.This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Experimental Verification of a Depth Controller using Model Predictive Control with Constraints onboard a Thruster Actuated AUV [PDF]
, 2012 In this work a depth and pitch controller for an autonomous underwater vehicle (AUV) is developed. This controller uses the model predictive control method to manoeuvre the vehicle whilst operating within the defined constraints of the AUV actuators ...

Multi‐Platform Deployments of Low‐Cost Devices for Cetacean Passive Acoustic Monitoring
Remote Sensing in Ecology and Conservation, EarlyView.Recent advances in affordable, user‐friendly devices offer new opportunities to overcome cost constraints of underwater passive acoustic monitoring (PAM) and expand acoustic data collection. In this study, we deployed low‐cost acoustic recorders and underwater cameras across a range of platforms in the Western Mediterranean, including fishing gear ...

Science Education, EarlyView.ABSTRACT This study examines how integrating sustainability through socio‐scientific issue (SSI) in secondary chemistry teaching shapes epistemic openness and closure from a decolonial perspective, as mediated through classroom discourse. Drawing on a co‐planned lesson on copper mining in Chile – a scientifically rich yet ethically and politically ...

Small, EarlyView.ABSTRACT The rapid expansion of the Internet of Things (IoT) and wearable electronics necessitates sustainable power sources to replace the limited electrochemical battery. While mechanical energy harvesting offers a promising solution, traditional harvesters face challenges of irregular and low−frequency environmental sources. This review presents the

Geometric bounding techniques for underwater localisation using range-only sensors
This paper describes the application of geometric bounding techniques to range-only navigation of an underwater vehicle. A geometric technique is defined to obtain a position fix of an underwater vehicle using a combination of dead-reckoning navigation ...
