New Difference Triangle Sets by a Field‐Programmable Gate Array‐Based Search Technique

Journal of Combinatorial Designs, Volume 34, Issue 1, Page 37-50, January 2026.
ABSTRACT We provide some difference triangle sets with scopes that improve upon the best known values. These are found with purpose‐built digital circuits realized with field‐programmable gate arrays (FPGAs) rather than software algorithms running on general‐purpose processors.

FPGA Realization of a Novel Hyperchaos Augmented Image Encryption Algorithm

IET Computers &Digital Techniques, Volume 2026, Issue 1, 2026.
With the rapid growth of multimedia communication, protecting image data has become increasingly critical. This article proposes a novel 3‐stage hyperchaos‐based augmented image encryption technique (3SHAIET) that utilizes a three‐stage process with chaotic systems of increasing dimensionality (e.g., six‐dimensional [6D], 8D, and 9D) to enhance ...

A Novel Image Steganographic Method Based on Enhanced PIWT and Modified Optimal Pixel Adjustment Process

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel image steganographic method based on an enhanced Pyramid Integer Wavelet Transform (PIWT) combined with a Modified Optimal Pixel Adjustment Process (MOPAP). The PIWT enables integer‐to‐integer transformation, avoiding floating‐point computations and improving its suitability for efficient implementation.

Design a Third‐Order DDSM With Effective Random Dither in Fractional Frequency Synthesizers to Reduce Fractional Spurs

Journal of Electrical and Computer Engineering, Volume 2026, Issue 1, 2026.
In this paper, a new method for multistage digital sigma–delta modulators (DDSMs) is presented to increase the output sequence period and reduce fractional spurs. The output of a DDSM is always a periodic signal when the input is constant. A hybrid DDSM is premiere to its conventional counterpart for having a potential speed, by the choice of its ...

Hardware Implementation of Bayesian Decision‐Making with Memristors

Advanced Electronic Materials, Volume 11, Issue 16, October 6, 2025.
Lightweight Bayesian operators, implemented by integrating memristors with Boolean logics, exploit the switching stochasticity of the memristors to perform probabilistic data encoding and logic operations that are essential for Bayesian inference and fusion.
