The use of active sonar to study cetaceans [PDF]
, 2012 Cetacean species face serious challenges worldwide due to the increasing noise pollution brought to their environment by human activities such as seismic exploration. Regulation of these activities is vaguely defined and uncoordinated.

International Journal of Naval Architecture and Ocean Engineering, 2017 Naval ships are assigned many and varied missions. Their performance is critical for mission success, and depends on the specifications of the components. This is why performance analyses of naval ships are required at the initial design stage. Since the

Photonic Neuromorphic Processing With Coupled Spiking Silicon Microrings
Laser &Photonics Reviews, EarlyView.A neuromorphic photonic core composed of three self‐pulsing silicon microring resonators is experimentally demonstrated for analogue and digital processing. Richer computational capabilities emerge under injection conditions where the dynamics are nonlinear and coupled, yet remain reproducible, opening novel strategies for future on‐chip training and ...

FLSea: Underwater Visual–Inertial and Stereovision Forward‐Looking Data Sets
Journal of Field Robotics, EarlyView.ABSTRACT Visibility underwater is challenging and degrades as the distance between the subject and the camera increases. That is why forward‐looking underwater computer vision tasks are difficult. We have collected underwater forward‐looking stereovision and visual–inertial image sets using two underwater imaging platforms, a stereo camera rig, and an ...

Tonal signal detection in passive sonar systems using atomic norm minimization [PDF]
EURASIP Journal on Advances in Signal Processing, 2019 Abstract Frequency estimation of a tonal signal in passive sonar systems is crucial to the identification of the marine object. In the conventional techniques, a basis mismatch error caused by the discretization of the frequency domain is unavoidable, resulting in a severe degradation of the object detection quality. To overcome the basis
