... start with the same angle, that is δ(0) = 0, and in order to provide for the required active and reactive powers according to the corresponding reference values, at steady-state a nonzero angle difference is needed. Clearly, this depends also by the local loads. In Fig. 7 it is shown the time evolut ...

... All the numbers in the examples above are composite numbers because they have factors other than one and themselves. Said another way, each composite number contains 1 and itself as factors as well as at least one other number. In order to find all the prime factors of a composite number, we will u ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
