The Kosair Children's Hospital, located in Louisville, Kentucky, is the only children's hospital in the state. Recently, the hospital's emergency department has developed concerns with patient satisfaction. Patients have experienced excessive...
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...
An investigation was made into the relative costs of excavation retention by two systems: conventional soldier pile-wale-tieback support, and support by soil nailing. The investigation included design of excavation supports by the two...
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...
Image processing; Computer vision; Pattern recognition systems
Image segmentation is one of the most important problems in image processing, object recognition, computer vision, medical imaging, etc. In general, the objective of the segmentation is to partition the image into the meaningful areas using the...
This thesis is based on work done as part of a bigger project supported by Naval Research Laboratories (NRL). A MOSIS fabricated micro hotplate is simulated using the CAD software CoventorWare. There are three different sized hotplates in one die;...
The airline regulatory communities are interested in methods that can access degradation in the polymer insulation of aging aircraft wiring. This study investigates the response of bulk polymer films and aircraft wiring under indentation; changes...
The properties of gold nanoparticles (GNP) holds promising potential for drug delivery, diagnostics, plasmonic photothermal therapy of diseases, electronics, catalysis, and photovoltaics (Liu et al., 2006; Huang et al., 2003; Thompson, 2007;...
The use of fiber reinforced polymer materials (composite FRP materials) to
strengthen existing concrete structures continues to expand as our current infrastructure
ages. However, one of the concerns when using FRP systems in this manner is...
Three lab concrete mixes and one field concrete mix were evaluated to establish
the Air Void Analyzer (AVA) as a means of real-time, ���In-the-Field��, Quality Control
testing method. In this study, both the Air Void Analyzer and...
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,...
Item response theory; Goodness-of-fit tests; Monte Carlo method
Item response theory (IRT) is expanding to diverse research settings, without accompanying access to easily implemented model fit methods. One simple model fit approach involves x2/df ratios. However, its utility is not known across several...
The Faroe Islands are a small archipelago in the North Atlantic. With a current population of approximately 49,000 individuals and evidence of high levels of genetic drift, the Faroese are thought to have remained highly homogeneous since their...
Mixed-effects model is an efficient tool for analyzing longitudinal data. The random effects in mixed-effects model can be used to capture the correlations among repeated measurements within a subject. The time points are not fixed and all...
This paper investigates the development and applications of the Black-Scholes
formula. This well-known formula is a continuous time model used primarily to price
European style options. However in recent decades, observations in financial market...
Acetone--Analysis; Air quality monitoring stations
Zinc oxide (ZnO) based gas sensors with sliver ion exchanged ZSM-5 (Ag+ZSM-5) zeolite overlayer were created and tested for detection of acetone vapor in air. The ZnO and Ag+ZSM-5 films were deposisted on 400µm by 400µm platinum interdigitated...
Nonparametric statistics; Estimation theory; Distribution (Probability theory)
Multistate models are a type of multi-variate survival data which provide a framework for describing a complex system where individuals transition through a series of distinct states. This research focuses on nonparametric inference for general...
The phase II clinical trial is a critical step in the drug development process. In the oncology setting, phase II studies typically evaluate one primary endpoint, which is efficacy. In practice, a binary measurement representing the response to the...
A blinded observational cross-sectional in vitro study was conducted to compare the diagnostic accuracy of observers viewing images made using cone beam computerized tomography (CBCT), panoramic radiography and linear tomography. The sample...
This study investigates the placebo effect in randomized controlled trials of low back pain. This effect has not been analyzed over time or in respect to low back pain. A meta-analysis was performed using the Pubmed/Medline database for low back...
