Marginal inference for waiting times in multi-stage time-to-event models is complicated by right censoring of observations as well as the prior history of events in the model. In general, complications arise due to the evolution of the censoring...
In this dissertation research, we aim to solve problems of two types of survival data, clustered survival data with potentially informative cluster size and sojourn time data. The methods for these two types of data are different. However, both...
This dissertation is an examination of fire department response times in eight major cities of the United States including Houston, TX, Charlotte, NC, St. Paul, MN, Portland, OR, Seattle, WA, Louisville, KY, San Francisco, CA and Miami, FL. This...
Scheduling--Computer programs; Social work administration--Data processing; Public welfare administration--Data processing
The client flow of the Kentucky Cabinet for Health and Family Services is a complex process that deals with a high volume of clients on any given beginning half of the month. A simulation model of an average busy day in the system was built using...
A common research interest in medical, biological, and engineering research is determining whether certain independent variables are correlated with the survival or failure times. Standard statistical techniques cannot usually be applied for...
Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in half the time...
Protein C (PC) is an important anticoagulant, antithrombotic, and antiinflammatory in blood plasma. PC deficiency can lead to severe venous thrombotic events, including lung embolism, stroke, and heart attack. In the body, PC is activated only when...
Cumberland Falls State Park (Ky.); Historic preservation--Kentucky
This thesis is an examination of Louisville Times editor Tom Wallace's fight to prevent the construction of a hydroelectric dam at Cumberland Falls, Kentucky between 1926 and 1931. By mining Wallace's recently cataloged personal papers, this study...
DENIOS manufactures steel structures for the storage, handling and containment of chemicals. The company has recently relocated into a larger manufacturing facility. This move will allow the manufacturing capacity of the company to grow for the...
Hospital care--Computer simulation; Hospitals--Computer simulation; Medical appointments and schedules
With more and more attention surrounding healthcare, Industrial Engineers have championed the task to help hospitals and outpatient centers operate as efficiently as possible. Simulation is often used to analyze hospital performance measures. The...
Nanoparticles; Imaging systems in medicine; Imaging systems in biology
Gold nanoparticles (GNPs) have shown beneficial properties for biomedical use, e.g., their non-toxic nature and surface properties for easy modification. Upon receiving light, they generate a strong surface plasmon field, which can alter the...
Parasites; Medical parasitology; Parasitic diseases
This thesis investigated infection dynamics of parasitic nematodes at both the population
and individual levels by exploring evolutionary and historical aspects of infection as well
as how host-parasite interactions influence virulence. In...
Hospitals--Emergency services--Quality control; Time management surveys
Kosair Children’s Hospital Emergency Department in Louisville, KY has been
reporting low patient satisfaction, which could result in a decrease in revenue and patients
for the hospital. Patient throughput times in Kosair’s emergency room have a...
The motivation to determine a viable alternative to petroleum based energy has risen in recent years due to increased greenhouse gas emissions, environmental pollution, and the fear of exhausting oil and natural gas reserves. Biodiesel derived from...
Materials management--United States--Data processing; Production control--Data processing; Inventory control--Data processing
Material Requirements Planning (MRP) is one of the earliest production scheduling approaches that utilizes computers. MRP is still regarded as one of the most widely used systems for production scheduling. Even though MRP has made contributions,...
Rising concerns about dependency on fossil fuels in the 21st century has sparked a growth in research for renewable energy sources. One renewable energy production process of interest is the reduction of cellulose into fermentable sugars by means...
Liberty--Philosophy; Enlightenment--France; Désert de Retz (Chambourcy, France); Gardens, English--France--Chambourcy
Freedom is a critical concept that helps shape the discourse of modern society and corresponding thoughts about people's private, public, cultural and spiritual lives. Standing at the fountainhead of the modern era, the Enlightenment was a critical...
The role of mothers, the constitution of families, and the power of their stories are the bedrock of my thesis, which is the first 90 pages of a novel entitled Playing House . In it, I hope to investigate the denotation and connotation of the words...
Breast--Cancer--Diagnosis; Medical screening; Breast--Radiography; Mobile hospitals
This study used the de-identified breast cancer screen data which recorded the
information of 58231 screens and 22534 participants with different background. The
analysis of disparities on age, ethnic, health insurance and screen location has been...
The purpose of this project was to compare the accuracy and reliability of linear measurements made on 2D projections and 3D reconstructions using Dolphin 3D software (Chatsworth, CA) as compared to direct measurements made on human skulls. The...
