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.

Voting Software for Fault-Tolerant Aircraft Flight Control Systems (1992)
Conference Proceeding
M. Bass, J., & J. Fleming, P. (1992). Voting Software for Fault-Tolerant Aircraft Flight Control Systems. . https://doi.org/10.1016/b978-0-08-042050-9.50018-x

An intelligent and robust voting service is proposed. The novel voting service, is capable of forming a consensus based on performance of redundant applications in the value, time and reliability domains. The voter is distributed using a hot backup a...

Process improvement and automation in construction: Opposing or complementing approaches? (1992)
Presentation / Conference
Koskela, L. (1992, June). Process improvement and automation in construction: Opposing or complementing approaches?. Presented at The 9th International Symposium on Automation and Robotics in Construction, Tokyo, Japan

It is widely recognized that there must be wide-ranging changes in construction before automation can be implemented in practice. On the other hand, the innovation rate of construction is rather low, and thus it is unclear, how the steps necessary...

Iterative learning control of multivariable plants (1992)
Thesis
Mohamed, S. Iterative learning control of multivariable plants. (Thesis). University of Salford, UK

In recent years, many researchers have proposed different iterative learning controllers, which unfortunately mostly require that the plants under control be regular. Therefore, in order to remove this limitation, various analogue and digital iter... Read More about Iterative learning control of multivariable plants.

Molecular characterisation and functional properties of gum arabic (1992)
Thesis
Randall, R. Molecular characterisation and functional properties of gum arabic. (Thesis). University of Salford

Semi-PreParative gel permeation chromatography (gpc) was used to isolate several molecular mass components of gum arabic. The u. v. (218 nm) gpc elution profile showed the presence of several prominent peaks; however, only one major peak (FAw 3.8 x 1...

Gas network optimisation using Nash equilibria derived from dynamic non-cooperative non-zero sum game theory (1992)
Thesis
Ramchandani, N. Gas network optimisation using Nash equilibria derived from dynamic non-cooperative non-zero sum game theory. (Thesis). University of Salford

Efficient management of the national gas grid in Great Britain involves a complex optimisation task to resolve the sometimes conflicting requirements of security of supplies to customers, contractual obligation to suppliers and the cost of transmis...

An experimental study of heat driven absorption cooling systems (1992)
Thesis
Delgado, R. An experimental study of heat driven absorption cooling systems. (Dissertation). University of Salford

The great need for cooling combined with Mexico's large availability of low enthalpy geothermal energy, makes it very attractive to utilize this resource for cooling using heat driven absorption systems. Mexico posseses large amounts of brine at t... Read More about An experimental study of heat driven absorption cooling systems.

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...

An in-situ combustion simulator for enhanced oil recovery (1992)
Thesis
Oklany, J. An in-situ combustion simulator for enhanced oil recovery. (Thesis). University of Salford

A multi-dimensional three phase flow simulator is written to simulate the process of in-situ combustion. It has six components (oxygen, inert gas, a light oil, a heavy oil, water, and coke). The inert gas consists of all the noncondensible gases o... Read More about An in-situ combustion simulator for enhanced oil recovery.

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...
