Exclusions Zones for Small Modular Reactors
The objective of this thesis is to estimate the size of the exclusion zone around a small modular reactor (SMR). The aim of such zone is to provide an atmospheric space sufficient to dilute any radioactive releases during an accident, to a level below the safe regulated radiation dose for the …

Optimized scheduling of highway work zones
Highway maintenance activities usually require lane closures and disrupt traffic operations. Because of budget constraints, project deadlines, and the resulting traffic impact, the objective of this dissertation is to improve the efficiencies of traffic operation and maintenance work, and minimize …

Halogens and trace elements in subduction zones
… elements in aqueous fluids in subduction zones was addressed by in-situ zircon solubility measurements in a hydrothermal diamond anvil cell. The zircon solubilities in aqueous fluids at 865-1025 oC and 6-20 kbar buffered by quartz are very low, ranging from 1.0 to 3.3 ppm Zr, and …

Crystallization of Isolated Amorphous Zones in Semiconductors
… detect, measure and track individual amorphous zones throughout a series of irradiation micrographs. Characteristic zone shrinkage behaviors were observed. A simple shrinkage model suggests that the defects responsible for regrowth are created very near the crystalline/amorphous interface. In …

Thermal Structure of Mid-Crustal Shear Zones
Analysis of quartz c-axis fabrics and microstructures from ductily deformed rocks allows for the examination of the kinematics associated with crustal deformation. This thesis expands on the current knowledge of the kinematic evolution of the Himalayas and Scottish Caledonides, by examining samples …

Mass transfer and chemical interactions in subduction zones
Subduction zones are important sites of material recycling on Earth, with volatiles playing key roles in mass transfer processes and magma formation. This thesis investigates outstanding questions associated with a continuum of interrelated processes that occur as oceanic plates descend in …

Assessing sentiment in conflict zones through social media
While it is widely accepted that polling can assess levels of popular support in a geographic area by surveying a cross-segment of its population, it is less well accepted that analysts can use social media analysis to assess sentiment or popular support within the same space. We examine this …

Transformational Learning Experiences: Changing Relationships and Comfort Zones
… and belonging; 3) stepping outside of comfort zones; and 4) challenging perspectives and avoiding confrontations. The participants noted there was a need to meet again as a group with the other adults from the course to discuss their experiences and reflections, as well as to have an …

Identification of Vulnerable Zones on Steel Railway Bridges
This research presents the static and dynamic analyses of steel railway bridges subjected to the action of moving trains on the Crocodile, Kalbaskraal, and Van Staden railway bridges located in the Western Cape. The parameters of the bridges were taken from the existing desktop information. …

Optimizing the construction planning of highway work zones
Highway work zones often cause traffic congestions and delays resulting in increased road user delay, traffic crashes, and vehicle emissions. The Federal Highway Administration (FHWA) and state DOTs are continuously seeking to improve work zone safety and mobility. To accomplish this, the layout of …

Context based detection of urban land use zones
This dissertation proposes an automated land-use zoning system based on the context of an urban scene. Automated zoning is an important step toward improving object extraction in an urban scene.

Grey zones: performances, perspectives, and possibilities in Kashmir
… Using Primo Levi's (1988) concept of "grey zones" to investigate how narratives from these spaces might be given theatrical form, this thesis utilised six concepts to frame the aesthetic, pedagogic, and ethical principles of a practice-based-research undertaking: Immersive Theatre, …

Aerial jurisdiction over safety zones surrounding maritime installations
… in relation to shipping and respect for safety zones, the concept of aerial jurisdiction over these legally unique areas still remains a controversial one. This despite the fact that overflight of these areas is both possible and likely by almost all aircraft, and that certain aircraft, …

Condensation Frosting: From Ice Bridges to Dry Zones
… we perform a systematic study of dry zones and derive a scaling law for dry zones that collapses all of our experimental data spanning a wide parameter space. We then show that almost always the underlying mechanism behind the formation of dry zones around any hygroscopic droplet is …

Imaging subduction zones: slab structure, fluids, and fault slip
… release, manifest at depth within subduction zones is currently poorly constrained, in part due to the sparsity of marine geophysical observations that cross from the incoming plate to the forearc at multiple locations along a subduction zone. To help address this gap, this thesis uses passive …
