Imaging Linear Polarimetry of Proto-planetary Nebulae: the Origins of Asymmetry
(Astronomical Society of the Pacific, 2000)
It now seems likely that asymmetries in the circumstellar envelope (CSE) of intermediate mass stars develop during the latter stages of mass outflow as a star approaches the tip of the AGB. These asymmetries in the CSE ...
Simultaneous light scattering and intrinsic fluorescence measurement for the classification of airborne particles
(2000)
We describe a prototype laboratory light-scattering instrument that integrates two approaches to airborne particle characterization: spatial light-scattering analysis and intrinsic fluorescence measurement, with the aim ...
Scalar field of non-paraxial Gaussian beams
(2000)
A family of closed form expressions for the scalar field of strongly focused Gaussian beams in oblate spheroidal coordinates is given. The solutions satisfy the wave equation and are free from singularities. The lowest ...
Making Sense of Information- A New Role for the Marketing Researcher
(2000)
The value of today's business is measured increasingly in terms of what it knows, rather than what it owns. Even so, whilst knowledge exists in most organisations it is regularly difficult to access. This paper addresses ...
A Bird's Eye View of Ocular Galaxies
(Astronomical Society of the Pacific, 2000)
Ocular galaxies are systems undergoing an in-plane, near grazing, prograde encounter. In addition to the interaction causing the formation of two long, symmetrically opposite tidal tails, during a short period after ...
The 'psychic pet' phenomenon: a reply to Rupert Sheldrake
(2000)
Rupert Sheldrake (1999a) has published a note in the previous issue of the Journal criticising our research into the ‘psychic pet’ phenomenon. Certain points arising from this criticism have also been included in his recent ...
The infrared jet in 3C 66B
(2000)
Analysis of human motion using snakes and neural networks
(2000)
A novel technique is described for analysing human movement in outdoor scenes. Following initial detection of the humans using active contour models, the contours are then re-represented as normalised axis crossover vectors. ...
Tidal dwarf candidates in a sample of interacting galaxies
(2000)
We present deep optical B,V,R images of a sample of 10 interacting systems which were selected for their resemblance to disturbed galaxies at high redshift. Photometry is performed on knots in the tidal features of the ...
