Subsurface Parameter Estimation In Oilfield Modeling, Fatin Alawam Jan 2015

Subsurface Parameter Estimation In Oilfield Modeling, Fatin Alawam

All ETDs from UAB

Inverse problems involving partial differential equations have many physical applica- tions. One of the most important applications is in petroleum reservoir modeling. The estimation of petroleum reservoir properties is an essential component in predicting reservoir behavior. Generally, oil and water are present together in petroleum reservoirs and the resulting reservoir model consists of two nonlinear partial differential equations. Much research deals with two phase flow in porous media assuming incompressibility, but a few researchers consider the weakly compressible case which generally applies when the reservoir model does not include a gas phase. In this thesis we assume the weakly compressible …

Role Of Macrophages In The Cardiomyopathy Associated With Obesity And Type 2 Diabetes, Mehak Goel

All ETDs from UAB

Obesity is a state of chronic low-grade systemic inflammation that, along with type 2 diabetes (T2D), increases the risk of developing cardiovascular disease (CVD). Despite the wealth of information on the link between macrophages and cytokines in adipose tissue and peripheral insulin resistance, their role in the pathogenesis of diabetic cardiomyopathy and cardiac diastolic dysfunction is unclear. We hypothesized that activated immune cell mediators, in particular monocytes and macrophages, are fundamental drivers of diet-induced obesity and diabetic cardiomyopathy. Herein, firstly, a diet-induced model of diabetic cardiomyopathy was developed in C57BL/6 mice by feeding a high fat diet (HFD, 45% kcal …


Novel Non-Invasive Assessment Of Pulmonary Arterial Impedance Using Velocity Transfer Function And Its Relation With Right Ventricular Remodeling, Ankur Gupta Jan 2015

Novel Non-Invasive Assessment Of Pulmonary Arterial Impedance Using Velocity Transfer Function And Its Relation With Right Ventricular Remodeling, Ankur Gupta

All ETDs from UAB

Pulmonary arterial (PA) impedance takes in to account pulsatile blood flow through elastic pulmonary arteries as compared to static pulmonary vascular resistance. Increased PA impedance is an early physiological manifestation of PA remodeling. Currently PA impedance can only be detected invasively, is expensive and cumbersome to calculate and thus not done in routine clinical practice. The ability to assess PA impedance non-invasively can provide fundamental insights in evaluation of patients with normal PA pressures or mild pulmonary hypertension such as in patients with chronic obstructive lung disease. Non-invasive evaluation of right ventricular (RV)-PA axis to detect patients who could develop …

Practical Extensions Of The Continual Reassessment Method, Amber Salter Jan 2015

Practical Extensions Of The Continual Reassessment Method, Amber Salter

All ETDs from UAB

This dissertation considers the presence of patient heterogeneity in dose finding studies using the likelihood-based time to event continual reassessment method (TITE-CRM). First, assuming group membership is known and the groups share some information regarding their maximum tolerated dose (MTD), we extend the two-group two-parameter CRM to the TITE-CRM. We examine the performance of the two-group two-parameter TITE-CRM for various scenarios where the true MTD for each group is different. We also consider the situation where the groups are truly homogeneous but a heterogeneous model is employed. Our simulations show that the method has some loss in accuracy compared to …
