This book presents a comprehensive review of the subject of gravitational effects in quantum field theory. Although the treatment is general, special emphasis is given to the Hawking black hole… Expand

The choices facing the system developer and the software development process are explained and systems design and production techniques are explained.Expand

An automatic repeat request (ARQ) scheme which pre-empts the need for the retransmission of data is described and numerical results show that, under a wide range of high error rate and/or long propagation delay conditions, considerable improvements in performance can be achieved with the scheme.Expand

Using a perturbation expansion to second order in a quantity determining deviation from conformal invariance the authors obtain general expressions for the number and energy densities at late times… Expand

AMONG the exact solutions to Einstein's field equations of general relativity are those describing black holes which rotate and/or carry electric charge. These solutions are novel in that they may be… Expand

It is shown that the method of adiabatic regularization, proposed by Parker & Fulling for the removal of divergences in the vacuum expectation value of the stress tensor of a quantized field… Expand

We show that creation of field quanta can occur even in conformally trivial situations, contrary to popular belief. This conformal-symmetry breaking owes its existence to the so-called conformal… Expand
