Normalized Study of Three-Parameter System in the Time Domain and Frequency Domain

open access: yesShock and Vibration, 2017
Three-parameter isolation system can be used to isolate microvibration for control moment gyroscopes. Normalized analytical model for three-parameter system in the time domain and frequency domain is proposed by using analytical method.

Wideband Channel Estimation and Prediction in Single-Carrier Wireless Systems

open access: yes, 2005
—In this contribution wideband channel estimation and prediction designed for single-carrier wideband wireless communications systems are investigated. Specifically, the single-carrier wideband pilot signal received by the receiver is first converted to ...

Characterization and computation of canonical tight windows for Gabor frames

open access: yes, 2000
Let $(g_{nm})_{n,m\in Z}$ be a Gabor frame for $L_2(R)$ for given window $g$. We show that the window $h^0=S^{-1/2} g$ that generates the canonically associated tight Gabor frame minimizes $\|g-h\|$ among all windows $h$ generating a normalized tight ...

Enhancing latent palmprints using frequency domain analysis

open access: yesIntelligent Systems with Applications
Latent palmprints are integral to crime scene investigations, constituting a significant portion of encountered prints. They often suffer from poor ridge impressions, noise, and pronounced creases, setting them apart from other palmprint types.

Comparison of Frequency Domain and Time-Domain Methods for Aeromechanical Analysis

open access: yesInternational Journal of Rotating Machinery, 2016
Unsteady flow around an oscillating plate cascade and that through a single compressor rotor subject to vibration have been computationally studied, aimed at examining the predictive ability of two low fidelity frequency methods compared with a high ...

Color vision in the comb frequency domain

open access: yesBiological Research, 2003
In 1982, Horace Barlow considered the question of human trichromacy in the context of information theory: according to the Sampling Theorem, three types of receptors covering the visible spectrum (400- -700 nm) might be sufficient to reconstruct the ...

Conversion of Dielectric Data from the Time Domain to the Frequency Domain

open access: yesAdvances in Electrical and Electronic Engineering, 2005
Polarisation and conduction processes in dielectric systems can be identified by the time domain or the frequency domain measurements. If the systems is a linear one, the results of the time domain measurements can be transformed into the frequency ...
