GPU Accelerated Refined Tensor Voting
Gathering and extracting meaningful and reliable information from visual data can be challenging, especially when dealing with noisy or incomplete data. Edge detection algorithms such as the Canny edge detector or the Sobel operator attempt to solve this issue by detecting and isolating image …

Evaluation of a refined lattice dome model
A general review of lattice dome geometry and connection details, leads to a modeling approach, which introduces intermediate elements to represent connections. The method provides improved modeling of joint behavior and flexibility for comparative studies. The discussion of lattice domes is …

A Refined Methodology for Calibrating Premium Connection Make-ups
Digital Image Correlation is used to generate high-spatial-density full-field displacement<br />and strain data of a connection box outer diameter for use in the calibration of finite element<br />make-up models. Image acquisition and data processing techniques are discussed and best<br />practice …

Refined Evaluation of Effective Prestress in the Varina-Enon Bridge
The Varina-Enon Bridge is a cable-stayed, post-tensioned segmental box girder bridge in Richmond, Virginia. A large flexural crack was noted by inspectors in July 2012 which prompted a number of investigations into the current condition of the bridge. Particular focus has been put on prestress …

Refined and advanced shell models for the analysis of advanced structures.
… to a significant increase in the development of refined theories for the modelling of shells. Classical two-dimensional models, which were frequently used in the past, are inappropriate for the analysis of these new structures: their modelling involves complicated effects that are not considered …

Closing the fibre gap in refined cereal product – quality and health
This thesis explores the incorporation of refined and chemically modified dietary fibres (DF) into widely consumed cereal products—pasta, cake, and bread—as a strategy to help close the fibre intake gap. Despite recommendations of 25–38 g/day, actual intake remains low, partly due to the dominance …

An evaluation of classical and refined equivalent-single-layer laminate theories
In this thesis, we study the static and free vibration response of symmetric and antisymmetric cross-ply laminated plates using different plate theories. Governing equations for two displacement-based third-order equivalent-single-layer theories have been developed. The first one is called the …

The photodissociation of small Aldehydes: a refined understanding of prototypical dynamical systems
H2CO is photolysed between 30000 cm-1 to 37500 cm-1 ascertaining the individual quantum yield of all five radical, molecular and triple fragmentation channels. Branching fractions are extracted from H atom velocity mapped ion (VMI) images and speed correlated REMPI spectra of CO(v = 0, 1). The …

Refined design expressions for in-plane girder stiffness and system buckling capacity
Lateral-torsional buckling at the system level (global buckling) has been the subject of several research studies over the past 20 years. This buckling mode often controls over conventional lateral-torsional buckling (buckling between braces points) when the girder system is long and narrow. One of …

Geometrically nonlinear analysis of composite laminates using a refined shear deformation shell theory
The theory is based on an assumed displacement field, in which the surface displacements are expanded in powers of the thickness coordinate up to the third order. The theory allows parabolic description of the transverse shear stresses, and therefore the shear correction factors of the usual shear …

Sociotechnical systems in campus stormwater management: impediments and driving forces for refined sustainable systems
Throughout the United States, stormwater runoff from streets and similar hardscapes has had detrimental effects, often resulting in flooding, erosion, and health concerns. This thesis focuses on stormwater management as it relates to university campuses and the benefits of having formal stormwater …
