Experiments with the site frequency spectrum
, 2010
"... Evaluating the likelihood function of parameters in highly-structured population genetic models from extant deoxyribonucleic acid (DNA) sequences is computationally prohibitive. In such cases, one may approximately infer the parameters from summary statistics of the data such as the site-frequency ..."

Measurements of the wavenumber-frequency spectrum
"... The prediction of the vibratory response of structures excited by turbulent flows im-plies a good knowledge of both aerodynamic and acoustic components of the wall pressure fluctuations. In the present work, experiments were aimed at measuring wall pressure fluctuations under turbulent flows, in ord ..."

the measurement of a complete map of cross-power spectral densities over a large area. A post-processing has been developed to transform the space-frequency data into wavenumber-frequency spec-tra. Results for the boundary layer are consistent with the Corcos model. Analysis of the spectra shows the presence
The site frequency spectrum of dispensable genes
, 2014
"... The differences between DNA-sequences within a population are the basis to infer the ancestral relationship of the individuals. Within the classical infinitely many sites model, it is possible to estimate the mutation rate based on the site frequency spectrum, which is comprised by the numbers C1,.. ..."

Fast estimation of the pattern frequency spectrum
"... Abstract. Both exact and approximate counting of the number of fre-quent patterns for a given frequency threshold are hard problems. Still, having even coarse prior estimates of the number of patterns is useful, as these can be used to appropriately set the threshold and avoid waiting endlessly for ..."

for an unmanageable number of patterns. Moreover, we argue that the number of patterns for different thresholds is an interesting summary statistic of the data: the pattern frequency spectrum. To enable fast estimation of the number of frequent patterns, we adapt the classical algorithm by Knuth for estimating
MANAGEMENT OF THE RADIO FREQUENCY SPECTRUM IN AUSTRALIA by
"... The electro-magnetic spectrum is a resource of crucial significance to communications and to the economy. Efficient economic management of the spectrum requires that it be allocated to users and uses so as to maximise the discounted net social benefit. The paper outlines the existing system of spect ..."

Non-equilibrium theory of the allele frequency spectrum
, 2006
"... A forward diffusion equation describing the evolution of the allele frequency spectrum is presented. The influx of mutations is accounted for by imposing a suitable boundary condition. For a Wright-Fisher diffusion with or without selection and varying population size, the boundary condition is li ..."

Comparison of parametric representations for monosyllabic word recognition in continuously spoken sentences
- ACOUSTICS, SPEECH AND SIGNAL PROCESSING, IEEE TRANSACTIONS ON
, 1980
"... Several parametric representations of the acoustic signal were compared as to word recognition performance in a syllable-oriented continuous speech recognition system. The vocabulary in-cluded many phonetically similar monosyllabic words, therefore the emphasis was on ability to retain phonetically ..."

phonetically significant acoustic information in the face of syntactic and duration variations. For each ~ arameter set (based on a mel-frequency cepstrum, a linear frequency cepstrum, a linear prediction cepstrum, a linear predic-tion spectrum, or a set of reflection coefficients), word templates were
Estimating the pattern frequency spectrum inside the browser
"... Abstract—We present a browser application for estimating the number of frequent patterns, in particular itemsets, as well as the pattern frequency spectrum. The pattern frequency spectrum is defined as the function that shows for every value of the frequency threshold σ the number of patterns that a ..."

A Practical Guide to Wavelet Analysis
, 1998
"... A practical step-by-step guide to wavelet analysis is given, with examples taken from time series of the El Nio-- Southern Oscillation (ENSO). The guide includes a comparison to the windowed Fourier transform, the choice of an appropriate wavelet basis function, edge effects due to finite-length t ..."
