Influence of Nano Titanium Dioxide Coating on the Dust Accumulation Behavior of Polymethyl Methacrylate

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Polymethyl methacrylate (PMMA) has the advantages of excellent transmittance, light weight, high impact strength, good weather resistance, etc. and can be used as a substitute of glass in solar energy utilization technology. Difference in the roughness of materials can lead to the difference in the adhesion of dust to their surfaces. In this paper, 194

A Quantitative Descriptor for Chalky and Discoloration Damage in Rice Grains

Journal of Food Quality, Volume 2026, Issue 1, 2026.
The quality assessment of chalky and discolored rice grains is often limited to either subjective methods or single‐value metrics that fail to capture the finer details of these damages. Despite being detectable and rich in visual features, there is a lack of a quantitative framework for characterizing these damages within a single rice grain in terms ...

Image fragile watermarking algorithm based on deneighbourhood mapping

IET Image Processing, 2022
To address the security risk caused by fixed offset mapping and the limited recoverability of random mapping used in image watermarking, a self‐embedding fragile image watermarking algorithm based on deneighbourhood mapping are proposed. First, the image
