An analysis of packet sampling in the frequency domain [PDF]

open access: yesProceedings of the 9th ACM SIGCOMM conference on Internet measurement, 2009
Packet sampling techniques introduce measurement errors that should be carefully handled in order to correctly characterize the network behavior. In the literature several works have studied the statistical properties of packet sampling and the way it should be inverted to recover the original network measurements.

Frequency domain analysis of pre-stressed elastomeric vibration isolators

open access: yesDefence 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.

Frequency Domain Horizontal Cross Correlation Analysis of RSA

open access: yesAdvances 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 and Frequency Domain Dynamic Analysis of Offshore Mooring

open access: yesJournal 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

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

open access: yesJournal 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 ...

Comparison of PSD Analysis Methods in Frequency Domain Fatigue Analysis [PDF]

open access: yes한국정밀공학회지, 2019
If fatigue failure occurs during aircraft operation, it can cause catastrophic injuries. So, it is necessary to study fatigue failure at the design stage. Frequency domain fatigue analysis is used to predict fatigue failure.

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]

open access: yes, 2009
At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

FLAME ANALYSIS BY SELECTED METHODS IN THE FREQUENCY DOMAIN

open access: yesInformatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2022
Diagnostics of pulverized coal combustion can be carried out in the field of process monitoring and analysis of measurement data. The information about changes in the flame is presented in the form of time series, which can be analyzed in the time and ...

Frequency Domain Analysis of Tractor Tyre Enveloping Properties

open access: yesInternational Journal of Engineering and Management Sciences, 2019
Main source of vibration excitation for off-road vehicles are ground profile undulations. Most unprepared terrains are characterized by wavelength of unevenness that is of the order of magnitude of the contact length between tire and ground, so that ...
