Information security has been one of the most sensible issues when designing communications systems; especially when this information is cataloged as confidential. This paper deals with a secure system that let you get access to privileged data, when the medium access is a wireless network based on IEEE 802.11 standard. The system designed is conformed by(More)
We give an elementary exposition of the Lanczos technique to solve the matrix eigenvalue problem. This Lanczos procedure is one of the most frequently used numerical methods in matrix computations, and it is one of the 10 algorithms that exerted the greatest influence in the development and practice of science and engineering in the 20th century.

We show the usefulness of the hypervirial theorem to obtain the matrix elements au m e n γ − for the Morse potential. Besides, it is known that the hydrogenlike atom can be studied as a Morse oscillator, then here we prove that these fact leads to an interesting method to calculate 2 1 k nl r nl % for the Coulomb interaction. 1.
