Development of FEA wide-base truck tire and soil interaction models
… a method to accurately construct a new virtual wide-base tire model, validate it, and then study rolling resistance of the tire on a hard surface. This thesis includes tire-soil interaction and effects of soil on tires rolling resistance. To accurately study rolling resistance on soft soil, …

Adjustment factors for MEPDG pavement responses considering three- dimensional analysis and wide-base tire
… this study suggests two adjustment factors based on FE analysis to bridge the gap between reality and MEPDG analysis. The first adjustment factor—developed utilizing 480 cases performed in ABAQUS and considering similar material properties and pavement structure—converts pavement responses …

Development and optimization of a wide base FEA truck tire model for prediction of tire-road interactions
… applications for a Finite Element Analysis (FEA) based tire model. Through the use of an Adaptive Response Surface Method (ARSM) optimization algorithm, the newly constructed wide base FEA truck tire model underwent a parameter-tuning procedure of its materials until the behaviour of the virtual …

Flexible Pavement Dynamic Response Analysis and Validation for Various Tire Configurations
… a dual-tire assembly (275/80R22.5) and a wide-base tire (455/55R22.5). To overcome the drawbacks in conventional pavement analyses, more advanced conditions such as the viscoelastic material characterization of HMA, the moving wheel load amplitude, surface tangential contact stresses, and …

Dogs and Technology: Our Most Beloved Companions in Twentieth and Twenty-First Century America
… theoretically diverse approaches. Drawing from a wide base of existing research and literature, both in the realm of human/technological and human/canine relationships, this paper seeks to draw new conclusions about how we interact with our devices and our dogs and what this might say about who we …

An Historical Inquiry into Thomas Jefferson's Influence on the American Educational System
… American Educational System. Jefferson had a wide base of ideas about various levels and aspects of education. Jefferson's diverse interests in different aspects of education had an influence on various facets of the American educational world. That interest therefore deserved a study to show …

The Skeletal Effects to the Maxilla after Rapid Maxillary Expansion using CBCT
… maxilla exhibits a triangular pattern with the wide base in the anterior, accounting for 55% of total expansion at PI, 45% at P2, and 38% at Ml. An additional alveolar bending/tipping component accounts for 6% of total expansion at PI, 9% at P2, and 13% at Ml. The remaining orthodontic (dental …

Oxford City PCG and PCT : a case study of collaboration
… study. The study demonstrated that the locality-wide base of PCG/Ts, their explicit health improvement remit, budgetary arrangements and the presence of clinicians on their governing bodies were aspects of their organisational forms which equipped them to facilitate collaboration. However, over …

Analysis of tire-pavement interaction and pavement responses using a decoupled modeling approach
… a linear viscoelastic material and the granular base layer is modeled as a nonlinear anisotropic material. The FE pavement model was used to analyze critical pavement responses in thin and thick asphalt pavements considering different damage mechanisms. This dissertation concludes that knowledge …

Genome-Wide Dynamics of Chromatin Maturation Following DNA Replication
… methods, while informative, lack the genome-wide base-pair resolution required to assess the dynamics of chromatin assembly and maturation in a spatial-temporal manner. To overcome the limitations of these studies, I have taken advantage of an epigenome mapping technique based on micrococcal …

Optimization of lateral position of autonomous truck platoons to improve roadway infrastructure sustainability
… wheel wander while comparing the effects of wide-base tires (WBT) and dual-tire assembly (DTA) on pavement life cycle costs. Historically, research has shown that WBT inflict greater damage on the pavement than do DTAs. However, these two tires have been assumed to have the same wheel wander …
