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...
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...
Radio frequency allocation; Wireless communication systems
Recently, the need for wireless and mobile communications has grown tremendously and it is expected that the number of users to be supported will increase with high rates in the next few years. Not only the number of users, but also the required...
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...
Xenoestrogens are spread throughout the environment affecting our daily
lives and may produce potential toxic effects on human health. The purpose of
this study was to develop a mechanistically reliable model capable of identifying
xenoestrogens....
Recent advances in high throughput methodologies offer researchers the ability to understand complex systems via high dimensional and multi-relational data. One example is the realm of molecular biology where disparate data (such as gene sequence,...
This dissertation is comprised of three essays that address the question: what
specific cognitions lead to the formation of entrepreneurial intentions?
Essay 1, "Explaining and Predicting Entrepreneurial Intentions,"...
Ozone forecast models using nonlinear regression (NLR) have been successfully applied to daily ozone forecast for seven metro areas in Kentucky, including Ashland, Bowling Green, Covington, Lexington, Louisville, Owensboro, and Paducah. In this...
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...
Public health surveillance; Social networks--Health aspects; Information storage and retrieval systems--Public health
Early information is crucial for policy makers and public health officials responsible for protecting the public from the virulent spread of contagious diseases. Current indicators of the spread of contagious outbreaks lag behind the actual spread...
Micro air vehicles (MAVs) are type of unmanned aircraft with a maximum length of 150 mm (6 in.) and flight speed of less than 10 m/s. Because their flight speed is comparable to the environmental wind speed coupled with their small size and low...
Intelligent transportation systems; Air quality; Air--Pollution
Environmental or air quality impacts of Intelligent Transportation Systems (ITS)
are very difficult to measure. Some researchers have attempted to quantify the effects of
individual ITS application on emissions; yet, the effects of ITS as a whole...
Practical nursing--Examinations, questions, etc.; Practical nursing--Study and teaching; Nursing students; Prediction of scholastic success
Nursing is one of the most frequently chosen programs by those entering postsecondary institutions in preparation for a career. This is in part due to the job opportunities available, interest in healthcare, and a pending shortage of nurses in...
This study focuses on the variation in structural response to synthetic ground motions derived from the latest attenuation models developed for the Central Eastern United States (CEUS) and used by the USGS to develop the latest edition (2008) of...
This study compared brief, single sessions of physical activity (PA, self-paced treadmill walking) and relaxation/meditation (R/M, the "Body Scan") on positive and negative affect and anxiety measures in female undergraduates. Both were...
Human exposure to mercury has been shown to cause a number of adverse health outcomes, predominantly neurological effects. The developing fetus is most susceptible, and even low levels of exposure have been shown to produce nervous system deficits....
Radio frequency allocation--Mathematics; Wireless communication systems--Mathematical models; Frequency spectra--Mathematical models
Multidimensional frequency estimation is a classic signal processing problem that has versatile applications in sensor array processing and wireless communications. Eigenvalue-based two-dimensional (2-D) and N -dimensional ( N -D) frequency...
Anxiety in adolescence; Parent and teenager; Parenting
This dissertation examined the prediction of anxiety symptoms over time during
developmentally significant periods - the transition to middle school (12 years old) and
the transition to high school (15 years old). Specifically, relationships...
Internet in education; Universities and colleges--Faculty--Attitudes; Education, Higher--Computer network resources; Education, Higher--Effect of technological innovations on
This study examined faculty levels of implementation of Web-based instructional technology (WBIT) and computer self-efficacy beliefs (CSE) as factors associated to faculty perception of institutional mechanisms and its relative importance as...
Electronic commerce--Corrupt practices--Prevention; Internet advertising--Corrupt practices; Internet fraud
Online search advertising is currently the greatest source of revenue for many Internet giants such as Google™, Yahoo!™, and Bing™. The increased number of specialized websites and modern profiling techniques have all contributed to an...
