The Asian Evolution Of High Speed Rail, Philip G. Laird Aug 2014

The Asian Evolution Of High Speed Rail, Philip G. Laird

Dr Philip Laird

In Australia, in 2001, the Howard government released an East Coast HSR Scoping Study. This followed two major investigations by the private sector into HSR options for Australia; the first being a Sydney Canberra Melbourne Very Fast Train as proposed in 1984 by CSIRO, and the second being the Sydney Canberra Speed HSR proposal.


High Speed Rail In Australia - Much Studied And Slow To Start, Philip Laird Aug 2014

High Speed Rail In Australia - Much Studied And Slow To Start, Philip Laird

Dr Philip Laird

High Speed Rail or HSR with electric passenger trains operating at speeds of 250km/h or more is now operational in 11 countries and has been under recent consideration in Australia for future operation between Melbourne, Canberra, Sydney and Brisbane. The paper outlines HSR studies in Australia and conditionally quantifies the potential reduction of aviation fuel use at up to 0.5m litres per annum from the introduction of HSR by 2020 in Australia with a reduction of external costs at $540m per annum by 2020. In addition, HSR in Eastern Australia by 2020 could allow for some 300 slots to be …

High dose rate (HDR) brachytherapy is a radiation treatment technique capable of delivering large dose rates to the tumor. Radiation is delivered using remote afterloaders to drive highly active sources (commonly 192Ir with an air KERMA strength range between 20 000 and 40 000 U, where 1 U = 1 uGy m2/h in air) through applicators directly into the patient's prescribed region of treatment. Due to the obvious ramifications of incorrect treatment while using such an active source, it is essential that there are methods for quality assurance (QA) that can directly and accurately verify the treatment plan and the …
