On the preservation of unitarity during black hole evolution and information extraction from its interior
For more than 30 years the discovery that black holes radiate like black
bodies of specific temperature has triggered a multitude of puzzling questions
concerning their nature and the fate of information that goes down the black
hole during its lifetime. The most tricky issue in what is known as information
loss paradox is the apparent violation of unitarity during the
formation/evaporation process of black holes. A new idea is proposed based on
the combination of our knowledge on Hawking radiation as well as the
Einstein-Podolsky-Rosen phenomenon, that could resolve the paradox and spare
physicists from the unpalatable idea that unitarity can ultimately be violated
even under special conditions.Comment: 8 pages, no figure
Performance Analysis of a System with Bursty Traffic and Adjustable Transmission Times
In this work, we consider the case where a source with bursty traffic can
adjust the transmission duration in order to increase the reliability. The
source is equipped with a queue in order to store the arriving packets. We
model the system with a discrete time Markov Chain, and we characterize the
performance in terms of service probability and average delay per packet. The
accuracy of the theoretical results is validated through simulations. This work
serves as an initial step in order to provide a framework for systems with
arbitrary arrivals and variable transmission durations and it can be utilized
for the derivation of the delay distribution and the delay violation
probability.Comment: ISWCS 201
