Publikováno v: Displays. 15:117-123

A high-resolution (1000 lines per inch) ferroelectric liquid crystal display operating at video rate has been demonstrated. The display uses the τ-V minimum mode of matrix addressing together with a Malvern drive scheme to give high speed and contra

The effect of an elastic basement in the interpretation of bottom loss data

Autor: N. R. Chapman, R. K. H. Falconer, R. W. Bannister

Publikováno v: The Journal of the Acoustical Society of America. 87:2044-2051

A bottom loss simulator has been developed to model low‐frequency bottom loss measurements obtained at sites in the SW Pacific around New Zealand. The data for frequencies below 100 Hz have been grouped into two types according to the bottom enviro

High-resolution ferroelectric liquid crystal display

Autor: R. W. Bannister, Jonathon R. Hughes, Damien Gerard Mcdonnell, C. J.T. Smith, A. Graham, H. A. Pedlingham, Dave C. Scattergood

Publikováno v: SPIE Proceedings.

A high resolution (near 1000 l.p.i.) ferroelectric liquid crystal display operating at video rate has been demonstrated. The display uses a novel mode of matrix addressing which together with an improved drive scheme gives high speed and contrast. De

The performance of ferroelectric liquid crysta displays are particularly sensitive to achieving the correct alignment conditions. Topographical studies of the surface layers of a colour FLCD have been made using tapping mode atomic force (AFM). The r

ATOC—New Zealand receiver site survey and acoustic test

Autor: K. M. Guthrie, Gary E. J. Bold, Murray D. Johns, Chris T. Tindle, J. S. Kay, R. W. Bannister, S. M. Tan

Publikováno v: The Journal of the Acoustical Society of America. 93:2380-2380

Possible New Zealand receiver sites for the ATOC experiment have been investigated. A suitable site requires a water depth of 2000 m at a distance of 30 nm or less from the coast and an unobstructed acoustic path to California. A detailed site survey

Some hydrological features of the South Fiji Basin

Autor: R. N. Denham, F. G. Crook, D. G. Browning, K. M. Guthrie, R. W. Bannister

Publikováno v: New Zealand Journal of Marine and Freshwater Research. 15:299-306

Expendable bathythermograph (XBT) and salinity observations were made along a north‐south section across the South Fiji Basin in March 1976, and XBT observations only were made in May 1976, January‐February 1977, and July 1978. The salinity secti

Deep sound channel noise from high‐latitude winds

Autor: R. W. Bannister

Publikováno v: The Journal of the Acoustical Society of America. 79:41-48

The contribution to underwater ambient noise from the persistent winds which blow at high latitude is discussed and estimated. Energy is ducted into low‐loss paths in the deep sound channel by favorable horizontal sound‐speed gradients. A concept

Low‐frequency surface interference effects in long‐range sound propagation

Autor: M. A. Pedersen, R. W. Bannister

Publikováno v: The Journal of the Acoustical Society of America. 69:76-83

Characteristics of surface decoupling loss are discussed for acoustic frequencies below 250 Hz. It is shown that large losses will occur at frequencies below 100 Hz and for source or receiver depths less than 25 m. A significant dependence of decoupl

Variability of low‐frequency ambient sea noise

Publikováno v: The Journal of the Acoustical Society of America. 65:1156-1163

In March 1976, measurements were made of the ambient sea noise in the South Fiji Basin to the northeast of New Zealand. As part of the analysis, the standard deviation of the noise in each 1/3‐ octave band between 10–500 Hz was computed. The effe
