Frequency domain analysis of pre-stressed elastomeric vibration isolators

Defence Technology, 2023
Two types of elastomeric vibration isolators used for equipment vibration isolation in aerospace vehicles are considered for the present study. These isolators are constructed using elastomers mounted in steel encasings.

Time and Frequency Domain Dynamic Analysis of Offshore Mooring

Journal of Marine Science and Engineering, 2021
The numerical procedures for dynamic analysis of mooring lines in the time domain and frequency domain were developed in this work. The lumped mass method was used to model the mooring lines. In the time domain dynamic analysis, the modified Euler method

Frequency Domain Horizontal Cross Correlation Analysis of RSA

Advances in Electrical and Computer Engineering, 2022
This study shows that a previously published cross correlation based power analysis (CCPA) attack applied to the Montgomery Ladder exponentiation steps of a Rivest Shamir Adleman (RSA) implementation can be improved by working in frequency domain.

Time-Domain Implementation and Analyses of Multi-Motion Modes of Floating Structures

Journal of Marine Science and Engineering, 2022
The study of wave-structure interactions involving nonlinear forces would often make use of the popular hybrid frequency–time domain method. In the hybrid method, the frequency-domain analysis could firstly provide the reliable and accurate dynamic ...

Frequency-Domain Analysis of Linear Time-Periodic Systems [PDF]

, 2004
In this paper, we study convergence of truncated representations of the frequency-response operator of a linear time-periodic system. The frequency-response operator is frequently called the harmonic transfer function. We introduce the concepts of input,

Output frequency response function-based analysis for nonlinear Volterra systems [PDF]

, 2007
Analysis of nonlinear systems has been studied extensively. Based on some recently developed results, a new systematic approach to the analysis of nonlinear Volterra systems in the frequency domain is proposed in this paper, which provides a novel ...

Spectrum-Efficient Triple-Layer Hybrid Optical OFDM for IM/DD-Based Optical Wireless Communications [PDF]

, 2020
In this paper, a triple-layer hybrid optical orthogonal frequency division multiplexing (THO-OFDM) for intensity modulation with direct detection (IM/DD) systems with a high spectral efficiency is proposed.

Nonparametric frequency domain analysis of nonstationary multivariate time series [PDF]

, 2002
We analyse the properties of nonparametric spectral estimates when applied to long memory and trending nonstationary multiple time series. We show that they estimate consistently a generalized or pseudo-spectral density matrix at frequencies both close ...

Ultrasound Domain Adaptation Using Frequency Domain Analysis [PDF]

2021 IEEE International Ultrasonics Symposium (IUS), 2021
A common issue in exploiting simulated ultrasound data for training neural networks is the domain shift problem, where the trained models on synthetic data are not generalizable to clinical data. Recently, Fourier Domain Adaptation (FDA) has been proposed in the field of computer vision to tackle the domain shift problem by replacing the magnitude of ...
