Addressed issues include estimation of time-frequency energy density (matching pursuit and spectrogram), choice of resampling statistics to test the hypothesis of change in one small region (resel), and correction for multiplicity (false discovery rate). Note that when ArchiMate talks about cardinality, UML (on the class level) talks about multiplicity. multiplicity and labeled in some arbitrary fashion), the empirical spectral distribution (ESD) is given by M n = 1 n Xn i=1 i: (1. Example: Description: A student has a unique student id and can enroll in any number of classes. It is used as a high-level logical data model, which is useful in developing a conceptual design for databases. In science and the humanities.
