Robotics‐assisted acoustic surveys could deliver reliable, landscape‐level biodiversity insights

Remote Sensing in Ecology and Conservation, EarlyView.
Deploying and maintaining sensors is often a major bottleneck in collecting rapid biodiversity data. We tested whether autonomous hopping drones equipped with acoustic recorders could collect reliable biodiversity data in Costa Rica. Using 26,000+ hours of existing audio from 341 sites, with machine learning detections of 19 bird species and spider ...

Design of Unmanned Underwater Vehicle (UUV) For Precision Targeting Using Simple PID-Controler [PDF]

, 2009
A model of an Unmanned Underwater Vehicle (UUV) for precision targeting using simple PID controller has been designed. The system has been assumed to have two-dimensional character, such that the mechanical control mechanism would be performed solely by ...

Programmed unmanned aerial vehicles show great potential for monitoring marine megafauna in specific areas of interest

Remote Sensing in Ecology and Conservation, EarlyView.
Targeted conservation measures are contingent on robust knowledge of spatio‐temporal animal distribution in areas of interest. We explore unmanned aerial vehicle (UAV) transect monitoring as a novel method for standardized digital aerial surveys of marine megafauna by investigating the fine‐resolution spatio‐temporal distribution of harbour porpoises ...

Load-Reducing Characteristics of Gas Screen During Underwater Launch of the Vehicle

Shanghai Jiaotong Daxue xuebao
During the underwater launching process, a gas screen channel is formed near the opening of the cylinder, which can effectively reduce the high-frequency pulsation load on the surface of the vehicle exiting the cylinder. Based on the volume of fluid (VOF)

Organizational Soundscapes and the Sonicity of Voices: The Power of the ‘Sounds’ that Carry ‘Words’

Journal of Management Studies, EarlyView.
Abstract Organizations are soundscapes – they resonate with sounds and particularly the sounds of voices. Somehow however voice sonics, that is the sounds of voices and not the words carried on those sounds, have escaped attention in management studies. This absence of analysis is peculiar given voice sonics' undoubted influence on management (they may

Polar Grid Navigation Algorithm for Unmanned Underwater Vehicles

Sensors, 2017
To solve the unavailability of a traditional strapdown inertial navigation system (SINS) for unmanned underwater vehicles (UUVs) in the polar region, a polar grid navigation algorithm for UUVs is proposed in this paper. Precise navigation is the basis for UUVs to complete missions.
