... As noted above, periodic signals are best analysed in the frequency domain while stochastic signals are usually more profitably analysed in the time domain. The analysis in the time domain often involves the comparison of two different signals while in the frequency domain analyses usually concern only one signal. The expectation value of the covariance function of uncorrelated signals is zero. ... In particular the ACF of a function with period P has the same value, P . ...

... Comparative study of Tl-2201 single crystals with different temperatures of superconducting transition by means of specific heat method. Abstract: . The comparison studies of the specific heat of Tl-2201 single crystals with the different oxygen concentration have led to the conclusion that the doping by oxygen, resulting in lowering of T c and increasing of number of paramagnetic centers, leads to diminishing of antiferromagnetic correlations contribution to the specific heat. ...

... There are several classifications of the exact methods. ... A more physical classification is that of Th.Wriedt (1998) where he devides the methods in 3 groups: Mie theory expansions (SVM), surface-based (PMM, EBCM, GMT, MoM) and volume-based (FDTDM, TLMM, FEM and various volume IEMs - CDM, DDA, etc.) methods.

... A detector map is used to provide a grid of positions over which to calculate and flux weight the ARF. The default detector map is 'flat' which has a weighting of 1.0 for each detector map pixel and is rectangular having sides which just encompass the region specified in the DSS. Only detector map pixels falling within the source region are included in the ARF calculation, e.g. for a circular source box, the pixels in the corners of the detector map will be ignored. ... flat : . ...
