Earth, Planets and Space, 2021 Taking into account the motional induction effect, in which the Earth crust that has finite electrical conductivity vibrates in the ambient geomagnetic field resulting in motionally induced electric current, we derive semi-analytical solutions of seismo ...

Physics‐Informed Neural Network‐Enabled Forward Prediction and Inverse Design of Ring Origami
Advanced Science, EarlyView.This work presents a KRT‐PINN framework that integrates Kirchhoff rod theory with physics‐informed neural networks for the forward prediction and inverse design of ring origami consisting of closed‐loop rods. The framework predicts stable states of segmented rings with prescribed natural‐curvature profiles and determines the natural‐curvature profiles ...

Robust Spectrum-Based Comparison of Multivariate Complex Random Signals
IEEE Access, 2019 We consider the problem of comparing two complex multivariate random signal realizations, possibly contaminated with additive outliers, to ascertain whether they have identical power spectral densities.

Generalization of the algebraic discrete fourier transform with application to fast convolutions
Linear Algebra and its Applications, 1990 The algebraic discrete Fourier transform (ADFT) over finite fields was introduced by \textit{T. Beth} [Verfahren der schnellen Fourier- Transformation (1984; Zbl 0536.65098)]. Now using the normal basis concept, the ADFT for finite commutative rings with identity is defined.

Inverse Discrete Fourier Transform-Discrete Fourier Transform Techniques for Generating and Receiving Spectrally Efficient Frequency Division Multiplexing Signals [PDF]
American Journal of Engineering and Applied Sciences, 2011 Problem statement: Spectrally Efficient Frequency Division Multiplexing (SEFDM) system promises bandwidth savings by multiplexing overlapped non-orthogonal sub-carriers. However, the loss of orthogonality results in increasing the complexity of generation and detection of the signal.

Spectrum analysis of digital UPWM signals generated from random modulating signals
Scientific ReportsThis work studies the spectrum of discrete-time Uniform-sampling pulse width modulation (UPWM) signals originating from stochastic input signals. It demonstrates that for ergodic input sequences of independent and identically distributed random variables,

The library of reference models of the physical layer signals
Наука. Инновации. Технологии, 2022 The wireless communication is very widely used information transmission systems. Wireless networks differ from cable networks on physical and partially on data link layer OSI in use of different methods of modulation.
