The effect of compressibility on turbulent shear flow: a rapid-distortion-theory and direct-numerical-simulation study [PDF]

open access: yes, 1997
The influence of compressibility upon the structure of homogeneous sheared turbulence is investigated. For the case in which the rate of shear is much larger than the rate of nonlinear interactions of the turbulence, the modification caused by ...

Rate-Distortion Bounds for Kernel-Based Distortion Measures

open access: yesEntropy, 2017
Kernel methods have been used for turning linear learning algorithms into nonlinear ones. These nonlinear algorithms measure distances between data points by the distance in the kernel-induced feature space.

Hyperbolic splines and nonlinear distortion

open access: yesIEEE Transactions on Signal Processing, 2000
Using Mobius transformations, we consider how to interpolate a set of monotone increasing data points (x/sub k/, y/sub k/) so that the interpolant is a smooth invertible function and that the interpolant and its inverse have the same simple functional form. We use our method to cancel jammer-induced distortion in a nonlinear channel.

Effects of intermodulation distortion on the performance of a hybrid radio/fiber system employing a self-pulsating laser diode transmitter [PDF]

open access: yes, 2003
A self-pulsating laser is used to generate a multicarrier (five radio frequency (RF) channels) microwave optical signal for use in a hybrid radio/fiber system. The self-pulsation is achieved by external light injection into the laser diode.

Distortion mechanisms in varactor diode-tuned microwave filters

open access: yes, 2006
This paper examines the broadband distortion behavior in flexible filters employing varactor-diode tuning elements. Series- and parallel-resonant varactor-loaded transmission-lines, both commonly used in bandpass and bandstop microwave filters, are ...

Comparison of Assessment Methods for the Connection of Nonlinear Loads to HV-EHV Power Systems

open access: yesZhongguo dianli, 2021
With the "double-high" development of power systems, the capacity of nonlinear loads or equipment is becoming increasingly larger, and the demand for their connection to the HV-EHV power systems is getting increasingly higher.

An Adaptive Fuzzy Logic System for the Compensation of Nonlinear Distortion in Wireless Power Amplifiers [PDF]

open access: yes, 2018
Computational intelligent systems are becoming an increasingly attractive solution for power amplifier (PA) behavioural modelling, due to their excellent approximation capability.

Evaluation of nonlinear distortion in optically switchable UWB filters

open access: yes, 2014
This article provides a complete evaluation of nonlinear distortion for a switchable ultrawideband (UWB) filter. The proposed structure can provide a good performance with very little loss.

Nonlinearities of GaAlAs lasers - Harmonic distortion [PDF]

open access: yesIEEE Journal of Quantum Electronics, 1980
Narrow stripe lasers ( 2-6 \mu m) and transverse junction lasers exhibit excellent linearity. The dependence of relative second-and third-harmonic distortion is investigated as a function of modulation frequency and modulation current. Relative second- and third-harmonic distortion of -50 and -70 dB is observed for an optical signal of 4 mW p-p ( f_{m}
