Improving random number generators by chaotic iterations. Application in data hiding
, 2010 In this paper, a new pseudo-random number generator (PRNG) based on chaotic iterations is proposed. This method also combines the digits of two XORshifts PRNGs.

Quantization-Based Image Watermarking by Using a Normalization Scheme in the Wavelet Domain
Information, 2018 To improve the invisibility and robustness of quantization-based image watermarking algorithms, we developed an improved quantization image watermarking method based on the wavelet transform and normalization strategy used in this study.

A robust watermarking technique based on image normalization
Revista Facultad de Ingeniería Universidad de Antioquia, 2013 This paper presents a robust watermarking method against geometric distortions and several other signal processing schemes. In the proposed watermarking method, image normalization is used to get geometric invariant features. The watermark embedding and

Rice response as affected by various fertilizer‐P sources under contrasting irrigation methods
Agrosystems, Geosciences &Environment, Volume 9, Issue 1, March 2026.Abstract Alternative fertilizer‐phosphorus (P) sources created by recycling excess nutrients from waste sources, such as struvite (MgNH4PO4·6H2O), require further research to determine their niche in agriculture and potential environmental implications.
