The time axis is common to the raw data and the wavelet map (background), for which the vertical axis is analogous to an inverse frequency (Section 10). The Mexican hat wavelet (Section 3) used for the background wavelet map (Section 5) measures the magnitudes of local maxima (blue-grey shades) and minima (yellow/red shades) as a function of time and duration. ...

Gradients in the Temperature of CMBR M. MELEK Cairo University, Egypt. A nonconventional approach is developed to nd the primordial angular gradient in the temperature of the Cosmic Microwave Background Radiation. It is found that it depends on the nowadays recent detected value of the angular gradient in the temperature of the CMBR, di erent rates of universe's expansion through its di erent phases and the cosmic time period of each phase. ...
