Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan

Limnology and Oceanography: Methods, EarlyView.
Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

From Planar to 3D Nanophotonic Lenses: Advancing Design, Fabrication, and Applications

Laser &Photonics Reviews, EarlyView.
Three‐dimensional nanophotonic lenses are enabled by an integrated workflow that links design parameterization, full‐wave electromagnetic simulation, computational optimization, and freeform fabrication. This Review summarizes how these tools expand optical design freedom beyond a single patterned plane by enriching the local meta‐atom response and ...

Stereo Calibration and Rectification for Omnidirectional Multi-Camera Systems

International Journal of Advanced Robotic Systems, 2012
Stereo vision has been studied for decades as a fundamental problem in the field of computer vision. In recent years, computer vision and image processing with a large field of view, especially using omnidirectional vision and panoramic images, has been ...

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel

Materials and Corrosion, EarlyView.
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Structural Performance of Hybrid Fiber–Metal Laminates Reinforced With Natural and Synthetic Fibers: Tensile, Dynamic–Mechanical, and Residual Stress Behavior

Polymer Composites, EarlyView.
Hybrid fiber‐metal laminates combining aluminum with carbon, glass, and sisal/epoxy layers. Sisal fibers maintained strength, improved strain and thermal stability, and reduced residual stresses with less synthetic fiber. ABSTRACT This work studied how hybridization between natural and synthetic fibers influences the structural tensile performance ...

String‐Stable Platooning Control of Connected Automated Vehicles Under Non‐Uniform Stochastic Communication Delays

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper is concerned with the platooning control problem of connected automated vehicles (CAVs) under non‐uniform stochastic vehicle‐to‐vehicle (V2V) communication delays. Most existing relevant studies assume uniform or deterministic or slowly varying delays, or design platoon controllers based on worst‐case delay bounds, resulting in ...

Linear System Identification and Control of a Low‐Cost High‐Performance Omnidirectional Marine Surface Vehicle for Swarming Applications

Journal of Field Robotics, EarlyView.
ABSTRACT Marine operations traditionally rely on human intervention, a costly and disruptive method. Autonomous surface vehicles (ASVs) offer a powerful alternative, capable of operating autonomously, for extended periods, and with various sensors for various missions.

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 ...
