An in depth evaluation of internal criteria for determining the number of clusters in a data set
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Clustering procedures partition data sets into groups, minimizing the distance within clusters while maximizing the distance between clusters. Clustering can be a powerful tool...
Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases on the major road...
Watershed-level Analysis of Urban Raingarden Performance
(2013)
Urban flooding became to be a big issue for many cities in the world due to the urbanization. Best Management Practices (BMP) are considered to be an economically friendly solution for the urban storm water problem.

Cognitive load and time based forgetting
(University of Missouri--Columbia, 2009)
Recently, various researchers have claimed that time does not play a direct role in shortterm forgetting. Instead, they claim that time is only related to forgetting because it is correlated with other factors that cause ...
Soil testing in Missouri : a guide for conducting soil tests in Missouri

Effects of amending a gravel based growing medium with calcined clay on medium physical properties and growth of Gymnocladus dioicus seedlings
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Missouri Gravel Bed (MGB) is a system that uses pea gravel with 10% sand (v/v) as a root growth medium, allowing bare root plants to be removed from the gravel and planted...
Multi-objective network optimization: models, methods, and applications
(University of Missouri--Columbia, 2021)
to both managers and users of the system. While there can be an infinite number of feasible solutions to any multi-objective optimization problem in large networks (e.g., urban transportation systems), the efficient ones are usually more desirable...
Quantitative Characterization of Billowed Structures Along the Margins of Basaltic Intrusions to Determine Process and Timing of Formation: Case Studies from Big Bend National Park, Texas and 71 Gulch, Idaho
(2021)
By constraining the conditions in which billowed structures form, the conditions of explosive vs. non-explosive magma-water interaction can be further revealed, improving our understanding of how magma propagates and ...
Toward a common market in residency: international migration and regional integration
(University of Missouri--Columbia, 2005)
This paper further develops models of regional migration, particularly in continents integrating regionally as it magnifies the importance of immigrant behavior for economists and policy-makers. I outline the history of ...
