Fractal modes in unstable resonators (1999)
Journal Article
Karman, G., Mcdonald, G., New, G., & Woerdman, J. (1999). Fractal modes in unstable resonators. Nature, 402, 138. https://doi.org/10.1038/45960

One of the simplest optical systems, consisting of two mirrors facing each other to form a resonator, turns out to have a surprising property. Here we show that the peculiar eigenmodes of unstable resonators are fractals, a finding that may lead to... Read More about Fractal modes in unstable resonators.

Integrated delivery systems for sustainable construction (1999)
Journal Article
Barrett, P., Sexton, M., & Green, L. (1999). Integrated delivery systems for sustainable construction. Building Research and Information, 27(6), 397-404

This study, based on a Delphi exercise and further analysis, provides a consensus view on sustainable development in relation to the construction industry, together with a broad improvement-oriented model. A pressure-state-response model has been inf... Read More about Integrated delivery systems for sustainable construction.

The relevance of GIS in the evaluation of vernacular architecture (1999)
Journal Article
Ford, M., Elkadi, H., & Watson, L. (1999). The relevance of GIS in the evaluation of vernacular architecture. Journal of Architectural Conservation, 5(3), 64-75. https://doi.org/10.1080/13556207.1999.10785252

In the present climate of financial restrictions, the importance of identifying those buildings that are of greatest value has increased. Identification necessitates knowledge, not only of the architectural and historic worth of a building, but also... Read More about The relevance of GIS in the evaluation of vernacular architecture.

A study into on-street parking: effects on traffic congestion (1999)
Journal Article
Yousif, S., & Purnawan. (1999). A study into on-street parking: effects on traffic congestion. Traffic engineering & control, 40(9), 424-427

This paper describes the characteristics of vehicle manoeuvres when entering or leaving on-street parking. Those manoeuvres are often ignored by traffic engineers in the design process and the evaluation of traffic management schemes. However, they...

Mapping and scheduling for heterogeneous architectures (1999)
Journal Article
Ramos-Hernandez, D., Tokhi, M., & Bass, J. (1999). Mapping and scheduling for heterogeneous architectures. Microprocessors and Microsystems, 23(1), 7-23. https://doi.org/10.1016/S0141-9331%2899%2900009-5

Extensive and computationally complex signal processing and control applications are commonly constructed from small computational blocks where the load decomposition and balance may not be easily achieved. This requires the development of mapping an... Read More about Mapping and scheduling for heterogeneous architectures.

Excess noise in low Fresnel number unstable resonators (1999)

A numerical algorithm is proposed for computing the eigenvalues of the linear scattering problem associated with the nonlinear Schrodinger equation. The numerical method allows a fast calculation of the dynamical evolution of the properties of optica...

History of sleeping sickness in East Africa. (1999)
Journal Article
G, H. (1999). History of sleeping sickness in East Africa. Clinical Microbiology Reviews, 12, 112-25. https://doi.org/10.1128/CMR.12.1.112

The history of human sleeping sickness in East Africa is characterized by the appearance of disease epidemics interspersed by long periods of endemicity. Despite the presence of the tsetse fly in large areas of East Africa, these epidemics tend to oc... Read More about History of sleeping sickness in East Africa..

Excess-noise dependence on intracavity aperture shape (1999)
Journal Article

In lasers with nonorthogonal eigenmodes the excess-noise factor K can be large, especially in unstable-cavity lasers with hard-edged intracavity apertures. To the best of our knowledge, we report the first detailed study of the dependence of K on ape... Read More about Excess-noise dependence on intracavity aperture shape.
