Underwater Image Enhancement Using An Integrated Colour Model. [PDF]

open access: yes, 2007
In underwater situations, clarity of images are degraded by light absorption and scattering. This causes one colour to dominate the image.

Blue Laser Underwater Optical Visible Light Communication Using Recursive OFDM

open access: yesWasit Journal of Engineering Sciences
Water covers more than 75% of the earth's surface in the form of the ocean. The ocean investigation is far-fetched because the underwater environment has distinct phenomenal activities.

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers

open access: yesLaser &Photonics Reviews, EarlyView.
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations

Can Environmental Markets Pay for More Sustainable Farm Dams? A Cost–Benefit Analysis

open access: yesSustainable Development, EarlyView.
ABSTRACT Farm dams are widespread artificial waterbodies that play a critical role in agricultural water security. Enhancing these systems through sustainable interventions such as fencing, hardened access points, and revegetation can improve water quality and deliver carbon and biodiversity co‐benefits.

Biomimetic and Gel‐Mediated Tissue Adhesive Structures for Skin Conformal and Multifunctional Bioelectronics

open access: yesSmall, EarlyView.
Inspired by octopus suction structures, a biomimetic epidermal electrode is developed as a durable, skin‐conformal platform for next‐generation wearable and therapeutic bioelectronics. The electrodes exhibit skin‐matching mechanical properties and achieve strong, reusable adhesion on wet skin, outperforming commercial electrodes by maintaining adhesion
