Investigating the Effects of Sparger Design in Column Photobioreactors
<p>This thesis consists of three different studies where designs of rectangular column photobioreactors (PBRs) are changed based on the sparger types, spacings, and positions. Computational Fluid Dynamics (CFD) is used to predict fluid flow patterns, thermal profiles and additional hydrodynamic and …

Lumped Parameter Model for a Self Powered Fontan Palliation of the Hypoplastic Left Heart Syndrome
<p>Out of all newborn infants with congenital heart disease (CHD), 8% have a single functioning ventricle. The Fontan surgical procedure, where the superior and inferior venous returns are connected directly to the pulmonary arteries to allow the single functioning ventricle to perfuse the systemic …

Prediction of Articular Cartilage Remodeling During Dynamic Compression with a Finite Element Model
<p>First, an in vitro growth experiment was performed to test the hypothesis that applying dynamic unconfined compression during culture produces het- erogeneous remodeling in newborn bovine articular cartilage explants. Het- erogeneous measures of cartilage microstructure were obtained by …

Finite Element Model of the Pediatric Hip Joint During the Barlow Maneuver
<p>Developmental Dysplasia of the Hip is the dysplasia or dislocation of an unstable femoral head in the acetabulum of the pelvis. This is a result of an abnormal or underdeveloped growth of the acetabulum and triradiate cartilages and/or an out of place and uncentered femoral head in the …

Assessment of force coordination and neuromuscular quickness in healthy adults
<p>Throughout daily life, it is necessary to handle and control innumerable objects. To do so, one’s hands must be precisely regulated. To ensure that an object is effectively manipulated, an individual must apply a grip force (GF) perpendicular to the object’s surface to overcome load force (LF), …

Knee Angles and Axes Crosstalk Correction in Gait, Cycling, and Elliptical Training Exercises
<p>When conducting motion analysis using 3-dimensional motion capture technology, errors in marker placement on the knee results in a widely observed phenomenon known as “crosstalk” [1-18] in calculated knee joint angles (i.e., flexion-extension (FE), adduction-abduction (AA), internal-external …

Subject-Specific Finite Element Predictions of Knee Cartilage Pressure and Investigation of Cartilage Material Models
<p>An estimated 27 million Americans suffer from osteoarthritis (OA). Symptomatic OA is often treated with total knee replacement, a procedure which is expected to increase in number by 673% from 2005 to 2030, and costs to perform total knee replacement surgeries exceeded $11 billion in 2005. …

Multi-Scale Fluid Flow Analysis of the Cardiovascular System
<p>The hypoplastic left heart syndrome (HLHS) is one of the rarest congenital heart diseases affecting infants. Out of 150 babies born, one baby suffers from congenital heart disease. Furthermore, nine percent out of those suffering from congenital heart disease specifically suffer from hypoplastic …
