WitrynaAs a model for an orientational glass, we consider quadrupoles on a simple cubic lattice with random Gaussian bonds Jij. We treat the fully isotropic model described by the Hamiltonian, where Si is the μ-th component of a m-component vector (both m = 2 and m = 3 are treated) and the sum extends over all nearest-neighbour pairs once. Monte … Autocorrelation, sometimes known as serial correlation in the discrete time case, is the correlation of a signal with a delayed copy of itself as a function of delay. Informally, it is the similarity between observations of a random variable as a function of the time lag between them. The analysis of autocorrelation … Zobacz więcej In statistics, the autocorrelation of a real or complex random process is the Pearson correlation between values of the process at different times, as a function of the two times or of the time lag. Let where Zobacz więcej The (potentially time-dependent) auto-correlation matrix (also called second moment) of a (potentially time-dependent) random vector For a Zobacz więcej Multi-dimensional autocorrelation is defined similarly. For example, in three dimensions the autocorrelation of a square-summable Zobacz więcej For a discrete process with known mean and variance for which we observe $${\displaystyle n}$$ observations $${\displaystyle \{X_{1},\,X_{2},\,\ldots ,\,X_{n}\}}$$, … Zobacz więcej In signal processing, the above definition is often used without the normalization, that is, without subtracting the mean and dividing by the variance. When the autocorrelation … Zobacz więcej For data expressed as a discrete sequence, it is frequently necessary to compute the autocorrelation with high computational efficiency. A brute force method based … Zobacz więcej In regression analysis using time series data, autocorrelation in a variable of interest is typically modeled either with an In Zobacz więcej

INTRODUCTION The slow dynamics of supercooled liquids and glasses have been actively discussed for thirty years from the view point of both spatial distributions of heterogeneities and long time correlations.
