Nosocomial infections; Catheterization--Complications; Drug resistance in microorganisms
Catheters represent an essential part of the management of critically and chronically ill patients. However, their use is often plagued by catheter related blood stream infections (CRBSIs), which are associated with increased morbidity, hospital...
Wind energy conversion systems; Wind power--Technological innovations; Wind power--Research
This thesis proposes a new Maximum Power Point Tracking (MPPT) algorithm employed in Wind Energy Conversion Systems (WECS). One of the major issues discussed in the literature concerning HCS is its inefficiency in detecting the peak power when...
New products--Management; Consumer satisfaction; Marketing--Management
A constant flow of innovative products which meets the needs of customers and therefore is a monetary success for the inventing organization is important for the long term success of organizations, especially in modem dynamic markets. As resources...
The main purpose of this research is to make a comparative study of the physical mechanisms related to highway noise barrier insertion loss and to evaluate and improve the accuracy of insertion loss of FHWA Traffic Noise Model (TNM) 2.5 comparedw...
The complexity of high-dimensional data creates a number of concerns when trying to analyze it. This data often consists of a response or survival time and potentially thousands of predictors. These predictors can be highly correlated, and the...
Computer vision; Pattern recognition systems; Human face recognition (Computer science)
Humans have the uncanny ability to perceive the world in three dimensions (3D), otherwise known as depth perception. The amazing thing about this ability to determine distances is that it depends only on a simple two-dimensional (2D) image in the...
In order to satisfy customer expectations, a ground vehicle must be designed to meet a broad range of performance requirements. A satisfactory vehicle design process implements a set of requirements reflecting necessary, but perhaps not sufficient...
United Parcel Service; Aeronautics, Commercial--Freight--Data processing; Forecasting--Data processing
This thesis develops a forecasting model to predict six different volume measures on a weekly and daily basis for UPS-Supply Chain Solutions (UPS-SCS). The volume measures are used by UPS-SCS to develop business plans, operation plans, and staffing...
Missing data is very common in survey research. However, currently few guidelines exist with regard to the diagnosis and remedy to missing data in survey research. The goal of this thesis was to investigate properties and effects of three selected...
This dissertation addresses two different problems: 1) coronal loop detection from solar images: and 2) salient contour group extraction from cluttered images. In the first part, we propose two different solutions to the coronal loop detection...
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...
We have measured the temperature-dependent thermal conductivity, K(T) of single walled carbon nanotubes from 300 K to 8 K by 3w methods. K(T) exhibits linear temperature dependence in the entire temperature range. Our results are in good agreement...
Nuclear magnetic resonance spectroscopy; Spectrum analysis--Data processing
Since its development, nuclear magnetic resonance (NMR) has become one of the primary methods of chemists for structure elucidation, which is the determination of a compound's molecular structure. Current software packages enable scientists to...
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...
Urbanization disrupts natural soil profiles and as watersheds are
urbanized, their surfaces become impervious and this will result in
reduction of infiltration. For this reason, many cities are facing problems
with treating runoff water. Best...
Computer-aided minimally invasive surgery (MIS) has progressed significantly in the last decade and it has great potential in surgical planning and operations. To limit the damage to nearby healthy tissue, accurate modeling is required of the...
Crossover design is a type of longitudinal study with each subject receiving different treatments in different time periods. It has been used frequently in the pharmaceutical industry and other medical fields to investigate the safety and efficacy...
Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system. Preventive maintenance involves a basic trade-off between the costs of conducting...
Heuristic; Production management; Personnel management--Data processing
The Naval Surface Warfare Center wishes to create a task assignment schedule
with a minimal training cost for workers to raise their skills to the required levels. As the
number of workers, skills, and tasks increase, the problem quickly becomes...
In recent years, a number of computational and statistical problems for identifying SNP-SNP interactions in high dimensional survival data have been studied, and several data mining approaches have been proposed. However, the relative performance...
