PLANAR GRAPHS, BIPLANAR GRAPHS AND GRAPH THICKNESS
… graphs that are not planar are K5 and K{3,3}. A biplanar graph is a graph whose edges can be colored using red and blue such that the red edges induce a planar subgraph and the blue edges induce a planar subgraph. In this thesis, we determine the smallest complete and complete bipartite graphs …

Rigid registration of MR and biplanar fluoroscopy
… the the rigid registration of MR data and biplanar, fluoroscopic radiographs of the head, by means of an intensity-based, measure of similarity. We investigate a number of similarity measures which have been applied in other multimodal registration contexts, including that of CT-fluoroscopy …

Reference Frame Regulation for a Biplanar Bicycle
The biplanar bicycle is an experimental vehicle configuration that has been the focus of recent autonomous vehicle research at Virginia Tech. Although the vehicle can be advantageous due to its zero-radius turning and ability to traverse discontinuous terrain, one key disadvantage of the …

Kinematics, Dynamics and Control of Single-Axle, Two-Wheel Vehicles (Biplanar Bicycles)
A two-wheeled, single-axle, differentially driven vehicle possesses many salient advantages when compared to traditional vehicle designs. In particular, high traction factor, zero turn radius, and inherent static and dynamic stability are characteristics of this configuration. Drive torque is …

The relationships among perceptual style, perceptual motor ability, and the acquisition of a complex biplanar motor skill
… blindforded, and the acquisition of a complex biplanar motor skill. The participants for this investigation were young (ages 9-17) female gymnasts (n = 17) who had all received at least one year of gymnastics training, and could perform the prerequisite skills required for this experiment. All …

A 3D neuromuscular model of the human ankle-foot complex based on multi-joint biplanar fluoroscopy gait analysis
… model of the human ankle-foot complex based on biplanar fluoroscopy gait analysis is presented. Biplanar fluoroscopy (BiFlo) enables three-dimensional bone kinematics analysis using x-ray videos and bone geometry from segmented CT. Hindered by a small capture volume relative to traditional …

MPM Modeling of the Impact of Compound Landslides on a Rigid Wall
… of different basal sliding characteristics of biplanar compound landslides on the post-failure mechanics and the interaction with rigid structures. The Material Point Method (MPM), an advanced numerical tool capable of simulating large deformations, captures the whole instability and the impact …

3D dynamic in vivo imaging of joint motion: application to measurement of anterior cruciate ligament function
… during dynamic activity in vivo using high-speed biplanar radiography in combination with magnetic resonance (MR) imaging was developed. In this technique, 3D surface models of the knee joint are created from MR images and registered to high-speed biplanar radiographs of knee motion. The use of MR …

The effects of rehabilitation interventions on hind limb kinematics in a rat model of osteoarthritis
… were applied to the MMT injury model. A custom biplanar high-speed video radiography system was chosen to measure the kinematics of the experimental rats and quantify the effects of the interventions. Prior to use, workflows needed to be developed for this system. Additionally, the system needed …

Mapping the relationship between morphology and function of the shoulder: implications for human evolution and musculoskeletal injury
… shoulder kinematics, my final study employed biplanar videoradiography to compare the motion of the scapula during two tasks imposing opposite loading profiles on the shoulder: a press-up and a pull-down. Scapula motion differed significantly between tasks, elucidating how the scapula may …

The Rise of Modern Avian Flight: Wing Movement and Joint Mobility Within Ornithurae
… bird cadavers representing nine species through biplanar fluoroscopy (XROMM) and quantified their *ex vivo* movement envelopes. I developed a new quantitative framework for joint mobility analyses in a phylogenetic context: the *EcoPhyloMobilitySpace*. This enabled me to investigate links between …
