Time-Series Analysis Of Clusters In City Size Distributions, Ahjond S. Garmestani, Craig R. Allen, K. Michael Bessey

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Complex systems, such as urban systems, emerge unpredictably without the influence of central control as a result of adaptive behavior by their component, interacting agents. This paper analyses city size distributions, by decade, from the south-western region of the United States for the years 1890–1990. It determines if the distributions were clustered and documents changes in the pattern of clusters over time. Clusters were determined utilizing a kernel density estimator and cluster analysis. The data were clustered as determined by both methods. The analyses identified 4–7 clusters of cities in each of the decades analysed. Cities cluster into size classes, …

Visualizing Complexity : A Spatial Analysis Of Decorative Geometric Pattern In The Islamic World, 900-1400 Ad, Tracy Elizabeth Harrison

Dissertations and Theses

This study explores how the use of complex decorative geometric patterns in Islamic architecture spatially relates to advances in the fields of science and philosophy in the Islamic world between the ninth and fourteenth centuries. This project examines hypotheses developed by vario~s scholars on the forces that shaped the use of these patterns (known as the geometric mode) in Islamic architecture. The prevailing assumption that advances in mathematics contributed to the use of the geometric mode is used as a starting point for subsequent analysis.

For this study, two spatial databases were created. One contains over two hundred and twenty …

Citizen Based Public Health Surveillance, Monitoring And Post-Event Assessments, Thomas Lyons Carr Iii

Thomas Lyons (Thom) Carr III Appl.Sc., CEM

When a sudden on-set emergency or disaster affects a region or the whole country, communities and neighborhoods should plan for the possibility that emergency and other civic services will be disrupted and unavailable (District of Columbia 2003a, 2003b, 2004; Doyle 2004; Siskiyou County Public Health/NorCalBT.com 2004). The event may be severe enough that the routine public health surveillance and monitoring system will be disrupted or the system will not be able to provide data quickly enough to support state and local decisionmaking. A temporary post-disaster system should be planned for and implemented. The epidemiologist supporting the local decision makers must …
