Following our recent idea of using plasmonic and nonplasmonic nanoparticles as nanoinductors and nanocapacitors in the infrared and optical domains [N. Engheta et al., Phys. Rev. Letts. 95, 095504 (2005)], in this work we analyze in detail some complex circuit configurations involving series and parallel combinations of these lumped nanocircuit elements at optical frequencies. Using numerical s...

Abstract: This paper focuses on the Fuzzy Frequency Response: Definition and Analysis for Uncertain Dynamic Systems. In terms of transfer function, the uncertain dynamic system is partitioned into several linear sub-models and it is organized into Takagi-Sugeno (TS) fuzzy structure. The main contribution of this approach is demonstrated, from a Theorem, that fuzzy frequency response is a bounda...

This paper presents a new method on the use of the gammachirp auditory filter based on a continuous wavelet analysis. The gammachirp auditory filter is designed to provide a spectrum reflecting the spectral properties of the cochlea, which is responsible for frequency analysis in the human auditory system. The impulse response of the theoretical gammachirp auditory filter that has been develope...

This paper analyzes the frequency response of a two-surface multipactor in a rf circuit. An equation for the frequency band in which steady state multipactor can occur is derived in terms of the secondary emission properties of the surface, the quality factor Q of the rf circuit, and the operating voltage. The steady-state multipactor current is also derived, and is shown to be in excellent agr...

Cardboard liners are often installed within automotive drive shafts to reduce radiated noise over a certain frequency range. However, the precise mechanisms that yield noise attenuation are not well understood. To overcome this void, a thin shell (under free boundaries) with different cardboard liner thicknesses is examined using analytical, computational and experimental methods. First, an exp...

In previous work we derived a mathematical model which allows the frequency response of a dendritic cell to be predicted. The model has three, key limitations: the model assumes that the intermediate co stimulatory molecule signal is constant; it is only possible to make predictions for a single cell and the model only takes into account the signal processing element of the dendritic cell algor...

The Modal Assurance Criterion (MAC) has been used for numerous years as a measure of correlation between test and analytical mode shapes. The fact that the MAC considers only mode shapes usually means that a separate frequency comparison must be used in conjunction with the MAC values to determine the correlated mode pairs. The mode shape correlation has generally been displayed as the MAC matr...

Original scientific paper This paper introduces a fuzzy logic system to analyse the frequency response of wind farms composed of variable speed wind turbine generators (WTGs). WTGs can provide frequency support by using their energy reserves. However, the frequency response of an individual WTG is different from that of other WTGs because of their respective actual wind speeds. The frequency re...

In this paper, frequency-domain analysis based on frequency sweep method is presented for a nonlinear double integrator and a new linear integrator. All the two types of integrators can estimate the onefold and double integrals of a signal synchronously. With respect to the linear double integrator, the nonlinear integrator has better estimation performance and stronger robustness. Importantly,...
