ChoiWiliams time frequency analysis of a three degree freedom nonlinear system
(Katholieke Universiteit Leuven, 2006)The response of a nonlinear mechanical oscillator, depending on the type of nonlinearity, to an excitation of particular harmonic might contain sub and superharmonics, transients and chaotic components. The conventional ...

Article
A compact multiband monopole antenna with a defected ground plane
(2008)A compact multiband antenna is proposed that consists of a printed circular disc monopole antenna with an Lshaped slot cut out of the ground, forming a defected ground plane. Analysis of the current distribution on the ...

Article
Estimation of rotational frequency responses
(2003)Rotational frequency response functions are potentially valuable for structural damage detection but are difficult to obtain because of the practical problems of applying a pure moment. In the literature various indirect ...

Frequencydomain characterization of Singular Spectrum Analysis eigenvectors
(Institute of Electrical and Electronics Engineers Inc., 2017)Singular Spectrum Analysis (SSA) is a nonparametric approach used to decompose a time series into meaningful components, related to trends, oscillations and noise. SSA can be seen as a spectral decomposition, where each ...

Information theoretic bounds for compound MIMO Gaussian channels
(2009)In this paper, achievable rates for compound Gaussian multipleinputmultipleoutput (MIMO) channels are derived. Two types of channels, modeled in the frequency domain, are considered when: 1) the channel frequency response ...

Minimum relative entropy criterion for damage detection and location
(2007)Relative entropy has been employed, as an alternative to other regularization methods, in solving illconditioned linear inverse problems. Damage detection when treated as structural modification imparted by the damage ...

Robust capacity of a Gaussian noise channel with channel and noise uncertainty
(2005)This paper is concerned with the problem of defining, and computing the capacity of a continuoustime additive Gaussian noise communication channel when the true frequency response of the channel, and the power spectral ...

Robust capacity of white Gaussian noise channels with uncertainty
(2004)This paper concerns the problem of defining, and computing the channel capacity of a continuous time additive white Gaussian noise channel when the true frequency response of the channel is not completely known to the ...
