Scanning diffractometer for the rapid analysis of microparticles and biological cells
Ludlow, I.K.; Kaye, Paul H. (1979-05-01)A laser diffractometer is described which employs a novel scanned array of optical light guides to record the angular intensity variation of light scattered radially by a particle throughout an arc of 180° in approximately ... -
Scattering of light from atmospheric ice analogues
Ulanowski, Z.; Hesse, E.; Kaye, Paul H.; Baran, A.J.; Chandrasekhar, R. (2003) -
Scattering of non-uniform incident fields by long cylinders
Ulanowski, Z.; Hesse, E.; Baran, A.J.; Kaye, Paul H.; Tongue, I. (University of Bremen, 2003)We investigate experimentally far-field scattering from cylinders with illumination non-uniform along the axis of the cylinder. Scattered intensity as a function of angle in two orthogonal directions is examined. Variation ... -
A silicon micromachined device for use in blood cell deformability studies
Tracey, M.C.; Greenaway, R. S.; Das, A.; Kaye, Paul H.; Barnes, A. J. (1995-08)An application of silicon micromachining to the analysis of blood cell theology is described. The system, based upon a micromachined flow cell, provides a specific measurement of each cell in a statistically significant ... -
Simultaneous light scattering and intrinsic fluorescence measurement for bioaerosol detection
Barton, J.E.; Hirst, Edwin; Kaye, Paul H.; Clark, J.M. (2000)Several workers have reported the development of systems which allow the measurement of intrinsic fluorescence from particles irradiated with ultra-violet radiation; see for example, Hairston et al (1997); Seaver et al. ... -
Simultaneous light scattering and intrinsic fluorescence measurement for the classification of airborne particles
Kaye, Paul H.; Barton, J.E.; Hirst, Edwin; Clark, J.M. (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 ... -
Simultaneous radar and aircraft observations of mixed-phase cloud at the 100m scale
Field, P.R.; Hogan, R.J.; Brown, P.R.A.; Illingworth, A.J.; Choularton, T.W.; Kaye, Paul H.; Hirst, Edwin; Greenaway, Richard (2004)Three UK C-130 aircraft flights performed in conjunction with the Chilbolton Advanced Meteorological Radar were carried out in mixed-phase clouds. The aircraft instrumentation included the Small Ice Detector (SID) and ... -
A single-particle multichannel bio-aerosol fluorescence sensor
Kaye, Paul H.; Stanley, W.; Hirst, E.; Foot, E. V.; Baxter, K.; Barrington, S.J. (2005)We describe a prototype low-cost multi-channel aerosol fluorescence sensor designed for unattended deployment in medium to large area bio-aerosol detection networks. Individual airborne particles down to ~1µm in size are ... -
Single-Particle Raman Spectrometer (SPaRS) for the non-destructive physico-chemical characterisation of aerosols
Greenaway, R.; Dalley, J.E.J.; Ulanowski, Z.; Hesse, E.; Kaye, Paul H. (2004)This project seeks to develop a prototype systems for the analysis of single levitated micrometre-sized particles captured from an ambient aerosol. The systems is designed to use Raman scattering to establish chemical ... -

Spatial light scattering analysis as a means of characterising and classifying non-spherical particles
Kaye, Paul H. (1998)The manner in which a particle scatters incident light is a function of the particle's shape, its size, its structure and its orientation with respect to the illumination direction, as well as to the wavelength and ... -
Stability characteristics of cylindrical fibres in an electrodynamic balance designed for single particle investigation
Hesse, Evelyn; Ulanowski, Zbigniew; Kaye, Paul H. (2002)An electrodynamic balance (EDB) of the double ring double disc type has been designed for studying single microparticles. It allows electrostatic particle injection and recovery as well as alignment of elongated particles. ... -
A test of cirrus ice crystal scattering phase functions
Field, P.R.; Baran, A.J.; Kaye, Paul H.; Hirst, E.; Greenaway, R. (2003)In-situ ice crystal scattering has been measured in cirrus cloud with the Small Ice Detector laser scattering probe. Using light scattered from single particles (maximum dimension ∼<100 μm) at 4–10° and 20–40° we have ... -
The Universal Cloud and Aerosol Sounding System (UCASS): a low-cost miniature optical particle counter for use in dropsonde or balloon-borne sounding systems

Using real-valued metaclassifiers to integrate binding site predictions
Sun, Yi; Robinson, M.; Adams, Roderick; Kaye, Paul H.; Rust, A.G.; Davey, N. (Institute of Electrical and Electronics Engineers (IEEE), 2005)Currently the best algorithms for transcription factor binding site prediction are severely limited in accuracy. There is good reason to believe that predictions from these different classes of algorithms could be used in ...
