In two recent papers, a description is given of a means of obtaining an arbitrarily narrow peak in the calculation of the autocorrelation function [J. C. Brown, and M. S. Puckette, "Calculation of a narrowed autocorrelation function," J. Acoust. Sec. Am. 85, 1595-1601 (1989) ] or era narrow valley in the calculation of an inverse autocorrelation [J. C. Brown, and M. S. Puekette, "Musical inform...

Detection of sedimentary cycles is difficult in fine-grained or homogenous sediments but is a prerequisite for the interpretation of depositional environments. Here we use a new autocorrelation analysis to detect cycles in a homogenous sediment core, E602, from the northern shelf of the South China Sea. Autocorrelation coefficients were calculated for different mean grain sizes at various depth...

Tick-borne encephalitis (TBE) is one of natural foci diseases transmitted by ticks. Its distribution and transmission are closely related to geographic and environmental factors. Identification of environmental determinates of TBE is of great importance to understanding the general distribution of existing and potential TBE natural foci. Hulunbuir, one of the most severe endemic areas of the di...

Species distribution models are generic empirical techniques that have a number of applications. One these applications is to determine which environmental conditions most important for species. The calculation this variable importance depends on assumptions, including the observations used estimate independent each other. Spatial autocorrelation, common feature factors confounds assumption. Be...

Autocorrelation in animal movements can be both a serious nuisance to analysis and a source of valuable information about the scale and patterns of animal behavior, depending on the question and the techniques employed. In this paper we present an approach to analyzing the patterns of autocorrelation in animal movements that provides a detailed picture of seasonal variability in the scale and p...

BACKGROUND As a common infectious disease, hand, foot and mouth disease (HFMD) is affected by multiple environmental and socioeconomic factors, and its pathogenesis is complex. Furthermore, the transmission of HFMD is characterized by strong spatial clustering and autocorrelation, and the classical statistical approach may be biased without consideration of spatial autocorrelation. In this pape...

Abstract. In fully developed turbulence, the velocity field possesses long-range correlations, 10 denoted by a scaling power spectrum or structure functions. Here we consider the autocorrelation 11 function of velocity increment Δu`(t) at separation distance time `. Anselmet et al. [Anselmet 12 et al. J. Fluid Mech. 140, 63 (1984)] have found that the autocorrelation function of velocity 13 inc...

The contribution of this paper is the adaption of data driven methods for decomposition of tangent shape variability proposed in a probabilistic framework. By Bayesian model selection we compare two generative model representations derived by principal components analysis and by maximum autocorrelation factors analysis.
