Application of Artificial Neural Networks to Ship Detection from X-Band Kompsat-5 Imagery

Applied Sciences, 2017
For ship detection, X-band synthetic aperture radar (SAR) imagery provides very useful data, in that ship targets look much brighter than surrounding sea clutter due to the corner-reflection effect. However, there are many phenomena which bring out false

Low‐Dimensional MOF Nanoarchitectonics: Progress in MOF‐2D Material Hybrid Architectures for Energy Conversion and Storage

Advanced Materials, EarlyView.
This review highlights the integration of metal‐organic frameworks (MOFs) and two‐dimensional (2D) materials through dimensional interface engineering. By addressing intrinsic limitations like poor conductivity and agglomeration, these hybrid architectures optimize interfacial charge and mass transport.

Effect of Surface‐Lubricant Compatibility on Bubble Formation in Lubricant‐Infused Surfaces

Advanced Materials Interfaces, EarlyView.
Lubricant‐infused surfaces reduce drag partly through bubbles that form when lubricant depletes. Using laser‐textured steel infused with silicone oil, we show that microbubble nucleation occurs even on surfaces fully wetted by the lubricant, regardless of chemistry.

Ship-Fire Net: An Improved YOLOv8 Algorithm for Ship Fire Detection

Sensors
Ship fire may result in significant damage to its structure and large economic loss. Hence, the prompt identification of fires is essential in order to provide prompt reactions and effective mitigation strategies. However, conventional detection systems exhibit limited efficacy and accuracy in detecting targets, which has been mostly attributed to ...
