REPORT ON THE CHATHAM ISLAND TAIKO AND CHATHAM ISLAND PETREL RECOVERY PROGRAMMES (1990/91) Published by: Department of Conservation

SUMMARY Two visits were made to the Chatham Islands in September 1990 and January 1991 to assist with the Chatham Island taiko and Chatham Island petrel recovery programmes. Four new CI taiko were caught and another was recaptured at the three main breeding burrows. A new CI taiko burrow was found this season. The nest chamber of burrow Tuku No. 10 was located and an adult CI taiko was found in...

Technical Note: The South Eastern and Chatham Railways Managing Committee

In 1898, two railways serving the south-east of England agreed to be managed by a joint committee. This paper finds clear statistical evidence of the negative impact this had on total economic costs, including opportunity costs of capital, as well as working expenditure. Thus, additional support was provided for the then British railway policy already strongly suspicious of railway mergers on c...

On measuring surface-wave phase velocity from station-station

7 We apply two different algorithms to measure surface-wave phase velocity, as a function of 8 frequency, from seismic ambient noise recorded at pairs of stations from a large European 9 network. The two methods are based on consistent theoretical formulations, but differ in the 10 implementation: one method involves the time-domain cross-correlation of signal recorded 11 at different stations;...

Robust Airline Fleet Assignment: Imposing Station Purity Using Station Decomposition

Fleet assignment models are used by many airlines to assign aircraft to flights in a schedule to maximize profit [Abara 1986, Hane et al 1995]. A major airline reported that the use of the fleet assignment model increased annual profits by more than USD100 million [www.informs.org, 2002] a year over three years. The results of fleet assignment models affect subsequent planning, marketing and op...
