The next step in the model is the consideration of the simultaneous usage of mobile services by mobile users. The simplest approach is used: the peak demand of users is built from adding the data rates required for each of the services, weighted by the penetration of each of them.
The Rosenbergs, former members of the American Communist Party, were implicated by Ethelâs brother-in-law, David Greenglass and a Philadelphia chemist, Harry Gold, who, after admitting to their own espionage activities, served as the primary witnesses in the trial.
The case against the Rosenbergs was circumstantial at best. At the beginning of the trial, the prosecution announced that it would call more than 100 witnesses, including prominent scientists, who would prove that Ethel and Julius Rosenberg were part of a plot to steal secrets for the Soviet Union. In the end, only 23 were actually called forward to testify.
