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...
Neutron diffraction studies on ABO₃ (A=La, Sr, B=Fe, Co, Ni, Cu, Mn, Ti) perovskite used in solid oxide fuel cell (SOFC) and double perovskite Ba₂YRu[0.85-subscript]Cu[0.15-subscript]O₆ superconductor

Pluton source varition over two magmatic pulses in the white-inyo range, central-eastern California : implications for paleozoic and mesozoic tectonic reconstructions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation uses compositions of plutons in the White-Inyo Range (WIR) of central-eastern California, which is an important tectonic boundary as it is the easternmost...
Rheological and morphological evolution of basaltic lava flows
(University of Missouri--Columbia, 2018)
the following research questions: (1) How does the rheology of active flows evolve during emplacement; and (2) How can we use flow morphology to infer the rheology of inactive flows? ... At Piton de La Fournaise (La R�union, FR DOM), I addressed the longstanding...
Biogeochemistry and inorganic geochemistry as indicators of the paleoenvironment and paleohydrology of the Al-Azraq Basin, Jordan
(2013)
This study investigates the biogeochemical and inorganic geochemical
indicators for past environments and paleohydrology of a high resolution sediment record
from the Al-Azraq Basin, Jordan. The second largest basin in ...
Mesoporous iron oxide energetic composites with slow burn rate, sustained pressure and reduced ESD sensitivity for propellant applications
(University of Missouri--Columbia, 2006)
because of its redox reaction with Al-particles. We have attempted to reduce the combustion wave velocity by infiltrating polymers inside porous Fe₂O₃ and combining it with Al-nanoparticles. Furthermore, modifications with the polymers can reduce...
Decadal mass balance of the Antarctic ice sheet from satellite radar altimetry and its contribution to global sea level change
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In this research, we estimated the decadal mass balance of the Antarctic ice sheet using the European Space Agency's ERS-1 and ERS-2 satellite radar altimeter data over the time...
The kinetics of non-catalyzed supercritical water reforming of ethanol
(University of Missouri--Columbia, 2008)
point, 374[degrees]C and 22.1 MPa, and exhibits both liquid and gas-like properties and acts a non-polar solvent. Since supercritical water is denser than steam, supercritical water reactors have the potential of being smaller than their catalytic...
Comparing the diversity, geographic distribution, and intraspecific variation of subterranean termites (Reticulitermes: Isoptera: Rhinotermitidae) occuring in woodlands and urban environments of Missouri using morphology and 16s mtDNA
(University of Missouri--Columbia, 2007)
. In urban environments they feed upon dead wood, and therefore infest and destroy man-made wooden structures. Missouri is considered to have a moderate risk for termite infestations when compared with the states of the southeast part of the country. Despite...
