Fall 2013
There are many design methodologies and philosophies intended to provide structural integrity or increase structural robustness, thereby making structures resistant to progressive collapse. However, there is little information that reveals sources and levels of inherent robustness in structural...

Optimal Design of Coke Drum Skirt Slots and Analysis of Alternative Skirt Support Structures for Thermal-Mechanical Cyclic Loading
DownloadFall 2017
The skirt-to-shell attachment weld on coke drums is susceptible to low-cycle fatigue failure due to severe thermal-mechanical cyclic stresses. Therefore, various skirt attachment designs have been proposed and implemented to reduce stress and thus improve reliability. The most common skirt design...

Physiological responses of glycophytic and halophytic grasses Poa pratensis, Poa juncifolia, and Puccinellia nuttalliana to salt stress
DownloadFall 2017
Responses of two halophytic grasses Puccinellia nuttalliana and Poa juncifolia to treatments with NaCl were compared with the glycophytic grass Poa pratensis to better understand salt tolerance mechanisms in these plants. The experiments were carried out under controlled-environment conditions...

Posterior Cranial Base Growth and Development Changes as Assessed Through CBCT Imaging in Adolescents
DownloadFall 2017
Introduction: Understanding craniofacial growth and development is important for accurate diagnosis, treatment planning and post treatment evaluation of orthodontic cases. Paramount to this is knowledge of the cranial base growth and development, since it is the foundation upon which the...

Relationship of human tongue volume with inter-dental maxillary and mandibular arch width, palatal axial cross-sectional perimeter, palatal index and root axial inclination
DownloadFall 2010
Objective : To determine the relationship of tongue volume as determined from Cone Beam Computed Tomography (CBCT) scan reconstructions with maxillary and mandibular arch width, axial cross-sectional palatal perimeter, palatal index and axial inclination of upper and lower first premolars and...

Buried steel pipelines are widely used in transportation and distribution of oil/gas products over long distance. The changing geo-environmental conditions over the line may subject the pipelines to unforeseen load combinations and prompt the failure and loss of containment of the pipelines that...

Spring 2018
Modern effort in radiotherapy to address the challenges of tumor localization and motion has led to the development of MRI guided radiotherapy technologies. Accurate dose calculations must properly account for the effects of the MRI magnetic fields. St-Aubin et al. (2015, 2016) have investigated...

Spring 2010
This thesis investigates stray losses in AC machines using the time-stepped finite element technique. Two aspects of this topic are involved in this thesis. The first aspect is to construct a finite element model for AC machine systems and develop an efficient numerical solution for the system...

The development and biomechanics of theropod teeth and comparisons with other reptiles: a functional analysis
DownloadSpring 2012
Teeth are important for taxonomic studies. They are often the only remains found of certain vertebrates in the fossil record. This is because they are more resistant to weathering than most bones, they are small, and they are generally abundant. Most reptiles have homodont dentition, and the...

The effects of defoliation on growth, reproduction and pollination of a non-native legume (Astragalus cicer) in the mixedgrass prairie
DownloadSpring 2017
Herbivory can lead to trade-offs between plant growth and reproduction as defoliated plants lose initial resource investments and have reduced photosynthetic capacity. This trade-off can lead to reduced investment into reproductive structures and have repercussions for floral traits, pollinator...
