PhD University of New South Wales (1980)

Awarded PhD degree for thesis “A Study of Teletraffic Measurement and Other Estimation Problems”, which combined theoretical modelling of Bayesian estimators as finite-state dynamical systems with a practical method for quantifying and managing the errors of measuring and forecasting telecommunications network traffic.

Photo Album

Snapped while on a break from INET '98. (See an interesting paper.) Genevois trams have an excellent ticketing system. The vending machine prints a ticket that tells you which tram to catch and where to change. Right are some street acrobats, with the "jet d'eau" in the background.

Visit to Cisco was very stimulating, even though the headquarters building looks plain from the outside. Different sort of charge comes from Electric Vehicle Charger in the parking lot at Fry's Electronics. No-one was using it that day (or maybe ever?).

The scuba diving took place on the Great Barrier Reef, while the boardwalk is at Santa Cruz. I put the two photos together because they both have something to do with salt water.

On the left, me visiting with a friendly resident by the beautiful 17 Mile Drive near Monterey. On the right, a picture of me outside Santa Clara Marriott, returning from visit with Network Appliance.

Of the many sights along 17 Mile Drive, this lone cypress tree, growing on an unprotected rocky headland, was one that caught my eye. It was a beautiful sight in the setting sun. A few other people have thought so too, for example: here, here, here, and here.

Syndicate group working hard on an e-business assignment, and me relaxing (syndicate group on the left and me relaxing on the right, of course).

Taking in the local sights during a break in the QoS Development Group Meeting in Chester, UK. And, on the right, taking in some delicious coconut milk in Malaysia 1990 with my family.
