Stress autocorrelation function in liquid rubidium
Physical Review A, 1988A molecular-dynamics simulation of the stress autocorrelation function \ensuremath{\eta}(t) is reported for a dense-liquid-rubidium model. The data indicate a rapid decay of the correlation function for t\ensuremath{\lesssim}0.3 ps and a somewhat slower time dependence thereafter.

Speech processing by splicing of autocorrelation function
ICASSP '76. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005A speech processing system named SPAC (SPlicing of AutoCorrelation function) is proposed in order to compress or expand the speech spectrum, to prolong or shorten the duration of utterance, and to reduce the noise level in speech signal. A period of short-time autocorrelation function is sampled and spliced after change of the time scale.

Finding Autocorrelation Functions
IEEE Transactions on Education, 1968Finding autocorrelation functions for stochastic processes can be a complex and frustrating problem for the student. In this short paper we present a systematic approach to this problem that should reduce, or at least compartmentalize, this complexity.

Generalized autocorrelation functions
Annual Meeting Optical Society of America, 1988The autocorrelation function (ACF) a, of a realvalued function f(x, y) (e.g., a monochromatic image) is ordinarily defined as Recently it has been proposed that in the study of spatial phase discrimination it might be useful to consider a generalized ACF.1 Suppose the nth order ACF of f is defined as Clearly af,1 (the ordinary ACF) fixes the power ...

Autocorrelation function for PMD emulators with rotators
Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003Polarization mode dispersion (PMD) is an increasingly important limitation in long-haul optical fiber communication as the per channel data rate increases. Since recirculating loops are commonly used for long-haul system design and experimentation, PMD emulators that accurately reproduce the statistics of straight-line WDM systems are increasingly ...

A note on the bounds on autocorrelation functions (Corresp.)
IRE Transactions on Information Theory, 1955Recently, bounds were shown to exist on the transient response of networks whose system functions were appropriately restricted. Since the impulse response and real part, of the system function are Fourier cosine transforms of each other and the autocorrelation function and power spectrum for stationary processes are similarly related, many of these ...

Examples of Autocorrelation Functions
1997The principal instrument for the description of the fluctuations of spin interactions following from molecular dynamics is the autocorrelation function, which is preferably used in its reduced form. In the following sections, typical examples of correlation function formalisms will be delineated.

The autocorrelation function and binocular brightness mixing
Vision Research, 1969Abstract In this investigation a theoretical model of binocular brightness mixing is tested. According to the model, the brightness of the binocular combination of any pair of monocular brightnesses is equal to the vector sum of the monocular brightnesses, each monocular brightness being weighted in proportion to the contour and contrast properties ...
