Efficient Coding of the Embedded Signal in Steganographic Systems with Multiple Access [PDF]
Problems of the Regional Energetics, 2021 Today, steganographic systems with multiple access are of considerable importance. In such sys-tems, the orthogonal Walsh-Hadamard transform is most often used for multiplexing and divid-ing channels, which leads to the need for efficient coding of the ...

Block subsampled randomized Hadamard transform for low-rank approximation on distributed architectures [PDF]
International Conference on Machine Learning, 2022 This article introduces a novel structured random matrix composed blockwise from subsampled randomized Hadamard transforms (SRHTs). The block SRHT is expected to outperform well-known dimension reduction maps, including SRHT and Gaussian matrices, on ...

Lyapunov Direct Method for Nonlinear Hadamard-Type Fractional Order Systems
Fractal and Fractional, 2022 In this paper, a rigorous Lyapunov direct method (LDM) is proposed to analyze the stability of fractional non-linear systems involving Hadamard or Caputo–Hadamard derivatives.

Reversible Hadamard transforms [PDF]
Facta universitatis - series: Electronics and Energetics, 2007 A coding method which reconstruct an original digital image without distortion is called "reversible coding". In case of the classical block transform coding (Cosine, Hadamard, Haar and etc) we have to make the number of levels of the transform coefficient very large in order to reconstruct the input signal with no distortion.

Deep Neural Network with Walsh-Hadamard Transform Layer For Ember Detection during a Wildfire
2022 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW), 2022 In this article, we describe an ember detection method in infrared (IR) video. Embers, also called firebrands, can act as wildfire super-spreaders. We develop a novel neural network with a Walsh-Hadamard Transform (WHT) layer to process the IR video. The

Design of Grover’s Algorithm over 2, 3 and 4-Qubit Systems in Quantum Programming Studio [PDF]
International Journal of Electronics and Telecommunications, 2022 In this paper, we design and analyse the Circuit for Grover’s Quantum Search Algorithm on 2, 3 and 4-qubit systems, in terms of number of gates, representation of state vectors and measurement probability for the state vectors.
