Optical vortices in beam propagation through a self-defocussing medium (1992)
Journal Article
Mcdonald, G., Syed, K., & Firth, W. (1992). Optical vortices in beam propagation through a self-defocussing medium. Optics Communications, 94(5), 469-476. https://doi.org/10.1016/0030-4018%2892%2990589-J

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...

Narrative structures within architectural videos (1992)
Journal Article
Rhodes, P., McCartney, K., & Powell, J. (1992). Narrative structures within architectural videos. Design Studies, 13(4), 355-378. https://doi.org/10.1016/0142-694X%2892%2990131-S

This paper reports on a research programme concerning the communication of architectural information through the use of video. In recent years, the general public have become increasingly interested in and aware of architecture. This has been at leas... Read More about Narrative structures within architectural videos.

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.

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... Read More about Process improvement and automation in construction: Opposing or complementing approaches?.

Gas network optimisation using Nash equilibria derived from dynamic non-cooperative non-zero sum game theory (1992)
Thesis

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... Read More about Gas network optimisation using Nash equilibria derived from dynamic non-cooperative non-zero sum game theory.
