Solutions to RMO-2014 problems
... 3. Suppose for some positive integers r and s, the digits of 2r is obtained by permuting the digits of 2s in decimal expansion. Prove that r = s. Solution: Suppose s ≤ r. If s < r then 2s < 2r . Since the number of digits in 2s and 2r are the same, we have 2r < 10 × 2s < 2s+4 . Thus we have 2s < 2r ...

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.
