From:Journal of Vibration and Control (Vol. 12, Issue 2) Peer-ReviewedAbstract: In this paper we aim to show the significance of spectral subtraction for the improvement of the sensitivity of scalar indicators (crest factor, kurtosis) within the application of conditional maintenance by...

From:Progress In Electromagnetics Research C (Vol. 38) Peer-ReviewedThis paper presents an effective weighted-[L.sub.1]-sparse representation of array covariance vectors (W-[L.sub.1]-SRACV) algorithm which exploits compressed sensing theory for direction-of-arrival (DOA) estimation of...

From:Journal of Speech, Language, and Hearing Research (Vol. 43, Issue 1) Peer-ReviewedAcoustic spectral analysis has been used to describe voice tremor with some success, but no feature distinguishing pathological from normal tremor has been clearly identified. To assist in monitoring voice tremor...

From:Journal of Research of the National Institute of Standards and Technology (Vol. 107, Issue 4) Peer-ReviewedA novel, spectrally tunable light-source utilizing light emitting diodes (LEDs) for radiometric, photometric, and colorimetric applications is described. The tunable source can simulate standard sources and can be used...

From:PLoS ONE (Vol. 11, Issue 7) Peer-ReviewedThe number of fluorescent labels that can unambiguously be distinguished in a single image when acquired through band pass filters is severely limited by the spectral overlap of available fluorophores. The recent...

From:Advances in Mathematical PhysicsPeer-ReviewedWe are concerned with the extension of a Legendre spectral method to the numerical solution of nonlinear systems of Volterra integral equations of the second kind. It is proved theoretically that the proposed method...

From:International Journal of OpticsPeer-ReviewedIt is proposed that a macroscopic theory of propagation and scattering of light through random media can be functional for the dye liquid flowing media in the microscopic levels too, with modest approximations....

From:Journal of Circadian Rhythms (Vol. 11) Peer-ReviewedAuthors: Antoni Díez-Noguera (corresponding author) [1] Background Virtually all living beings exhibit circadian rhythms that are manifested as oscillations with periods close to 24 hours in almost all their...

From:PLoS ONE (Vol. 15, Issue 5) Peer-ReviewedAuthor(s): Melisa Menceloglu 1, Marcia Grabowecky 1,2, Satoru Suzuki 1,2,* Introduction Because oscillatory dynamics are prevalent in the brain (e.g., [1]), many EEG, MEG, and Electrocorticography (ECoG) studies...

From:Journal of Voice (Vol. 19, Issue 3) Peer-ReviewedSummary: This study explored whether acoustic and perceptual features could distinguish comfortable from maximally projected acting voice. Thirteen professional male actors performed a passage from William Shakespeare's...

From:Construction and Building Materials (Vol. 63) Peer-ReviewedABSTRACT Bitumen characteristics are fundamental for the development of good performance in asphalt mixtures, particularly when the mix includes Reclaimed Asphalt (RA) as aged bitumen can strongly affect the...

From:Electronic Transactions on Numerical Analysis (Vol. 44) Peer-ReviewedA recycling Krylov subspace method for the solution of a sequence of self-adjoint linear systems is proposed. Such problems appear, for example, in the Newton process for solving nonlinear equations. Ritz vectors are...

From:Mathematics of Operations Research (Vol. 35, Issue 2) Peer-ReviewedThis paper studies the queue-length process in series Jackson networks with external input to the first station only. We show that its Markov transition probabilities can be written as a finite sum of noncrossing...

Spectral perspective on the stability of discrete-time Markov jump systems with multiplicative noise
We apply the spectrum analysis approach to address the stability of discrete- time Markov jump systems with state- multiplicative noise. In terms of the spectral distribution of a generalized Lyapunov operator, spectral... -
From:INFORMS Journal on Computing (Vol. 19, Issue 2) Peer-ReviewedA summary and an analysis are given for an experimental performance evaluation of WASSP, an automated wavelet-based spectral method for constructing an approximate confidence interval on the steady-state mean of a...

From:BMC Research Notes (Vol. 15, Issue 1) Peer-ReviewedObjectives Remotely sensed hyperspectral data are increasingly being used to assess crop development and growth throughout the growing season. Large datasets capturing key growth stages can be useful to researchers...
-
From:Mathematics of Operations Research (Vol. 33, Issue 2) Peer-ReviewedWe study analyticity, differentiability, and semismoothness of Lowner's operator and spectral functions under the framework of Euclidean Jordan algebras. In particular, we show that many optimization-related classical...
