We present numerical simulations and analysis of optical vortex propagation in a 3D self-defocussing medium. On plane wave background initial conditions composed of points and lines of phase discontinuity are shown, in some cases, to evolve towards a...

Hexagon patterns in optical bistability (1992)
Journal Article
Firth, W., Scroggie, A., McDonald, G., & Lugiato, L. (1992). Hexagon patterns in optical bistability. Physical Review A, 46(7), R3609-R3612. https://doi.org/10.1103/PhysRevA.46.R3609

The mean-field model of optical bistability in a ring cavity is extended to include diffraction in two transverse dimensions. Nonlinear analysis in the neighborhood of the instability of the homogeneous solution indicates the formation of stable hexa... Read More about Hexagon patterns in optical bistability.

Objective and subjective evaluation of reflecting and diffusing surfaces in auditoria (1992)
Thesis
Cox, T. Objective and subjective evaluation of reflecting and diffusing surfaces in auditoria. (Thesis). University of Salford

The performance of reflectors and diffusers used in auditoria have been
evaluated both objectively and subjectively.
Two accurate systems have been developed to measure the scattering
from surfaces via the cross correlation function. These have be... Read More about Objective and subjective evaluation of reflecting and diffusing surfaces in auditoria.

Lateral-torsional buckling of haunched members in portal frames : an assessment of BS 5950 : part 1 (1992)
Thesis
Junid, S. Lateral-torsional buckling of haunched members in portal frames : an assessment of BS 5950 : part 1. (Thesis). University of Salford

The research described in this thesis, relates mainly to the
current method of design of steel portal frame structures.
The study is divided into two major parts, first being the
full-scale test on a 24 metre span frame and the second
deals with... Read More about Lateral-torsional buckling of haunched members in portal frames : an assessment of BS 5950 : part 1.

The effects of seating on the acoustics of auditoria (1992)
Thesis
Davies, W. The effects of seating on the acoustics of auditoria. (Thesis). University of Salford

The two main attributes of seating in auditoria have been investigated. Tle first
is random incidence absorption. The second is the low-frequency selective
attenuation which seating can impart to sound travelling over it at grazing
incidence: the... Read More about The effects of seating on the acoustics of auditoria.

Developments in sandwich construction (1992)
Thesis
Tajbakhsh, S. Developments in sandwich construction. (Thesis). University of Salford

The research is divided into two parts. In the first
part the structural behaviour of sandwich beams using
timber-based facings and foamed plastic cores was
studied. Various available theories were examined and
the most appropriate theory for thi... Read More about Developments in sandwich construction.
