A robust underwater image enhancement algorithm

The Journal of Supercomputing
Abstract Capturing clear images in underwater environments is a major challenge in marine engineering. There are many issues to consider in obtaining clear underwater images. Such as climate, environment and human factors. The most important reasons are the atomization effect caused by dispersion and the color cast caused by inconsistent energy

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

Advanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

The Impact of the Latest 3D Technologies on the Documentation of Underwater Heritage Sites [PDF]

, 2013
Documenting underwater cultural heritage is a challenging undertaking. Underwater environment is not a man’s natural habitat and special equipment and devices had to be invented so that he could enter and study this environment.
