His
Dissertation analyzed the stop-and-wait retransmission
protocol for data integrity where the error environment
is highly correlated.
The
Dissertation was published as a monograph in the "Research
Notes in Mathematics" series of Pitman Books Limited
, London, 1982.
The
Dissertation contained the first general proof that
the key transform matrix involved in solving stochastic
models of the "M/G/1 Type" was the unique minimal solution
to a non-linear matrix functional equation.
