Earthquake Dream Symbol â An earthquake is a disturbing symbol in a dream, denoting life changes that may be catastrophic. It represents very physical things. Everything that causes your sense of stability is or may soon be in jeopardy, as indicated by the literal ground beneath your feet giving way in your dream.
The wavelet analysis is done in a similar way to the STFT analysis, in the sense that the signal is multiplied with a function, {\it the wavelet}, similar to the window function in the STFT, and the transform is computed separately for different segments of the time-domain signal.
In the formalism of quantum mechanics, the state of a system at a given time is described by a complex wave function, also referred to as state vector in a complex vector space. This abstract mathematical object allows for the calculation of probabilities of outcomes of concrete experiments.or example, consider a free particle. In quantum mechanics, there is waveâparticle duality, so the properties of the particle can be described as the properties of a wave. Therefore, its quantum state can be represented as a wave of arbitrary shape and extending over space as a wave function.
