Traffic Fractal Analysis and the Determine the Probability Call Blocking in Cellular Mobile Networks
The purpose of this article is analysis of fractal properties of traffic and its influence on the characteristics of telecommunication systems for a given quality of service (QoS) as invariant to scale throbbing traffic structure can significantly influence the network performance. Analysis of the causes and consequences of fractal in traffic, and to identify areas handover is an important task in the modeling of radio coverage in the environment base stations Radio Mobile [1]. The numerical analysis model is incomplete two streams available system of mass service (SMS) with expectations calling for the handover and determine the probability of each new call blocking, call handover-and-multiple-call handover in a mobile network cell
Observation of superluminal geometrical resonances in Bi2Sr2CaCu2O8+x intrinsic Josephson junctions
We study Fiske steps in small Bi2Sr2CaCu2O8+x mesa structures, containing
only few stacked intrinsic Josephson junctions. Careful alignment of magnetic
field prevents penetration of Abrikosov vortices and facilitates observation of
a large variety of high quality geometrical resonances, including superluminal
with velocities larger than the slowest velocity of electromagnetic waves. A
small number of junctions limits the number of resonant modes and allows
accurate identification of modes and velocities. It is shown that superluminal
geometrical resonances can be excited by subluminal fluxon motion and that
flux-flow itself becomes superluminal at high magnetic fields. We argue that
observation of high-quality superluminal geometrical resonances is crucial for
realization of the coherent flux-flow oscillator in the THz frequency range
